Restoring Zim’s Economy through embracing the transition of a Renewable Clean Energy Era

Restoring Zim’s Economy through embracing the transition of a Renewable Clean Energy Era

Zimbabwe still has a chance to restore its economy in the Renewable Clean energy Era.Renewable energy resources will support our economy, create jobs for the citizens and move Zimbabwe towards a cleaner and more reliable energy future.

 

By Tinashe Masimbe

As most Zimbabweans are losing their jobs each day because of the current economy stress and the unemployment rate of the country standing at 80%. The numbers of those in formal employment are steadily decreasing, as an economic squeeze tightens. More than 6000 people were reported officially retrenched in 2014.

The use of modern renewable energy technologies produces less pollution than burning fossil fuels especially with respect to net emissions of greenhouse gases, and the world coming together to achieve a legally binding and universal agreement on climate, with the aim of keeping global warming below 2°C . Local renewable energy resources also represent a secure and stable source of energy for our country and a potential source of jobs, economic development and improve gross domestic product.

Government of Zimbabwe is in the process of developing a renewable energy policy, according to ZERA in 2014. However, there is need for Zimbabwe to move at a faster pace. In 2009, the Union of Concerned Scientists conducted an analysis of the economic benefits of a 25 percent renewable energy standard by 2025; it found that such a policy would create more than three times as many jobs as producing an equivalent amount of electricity from fossil fuels resulting in a benefit of 202,000 new jobs in 2025.

Jobs directly created in the renewable energy industry and growth in renewable energy creates positive economic “ripple” effects. For example, industries in the renewable energy supply chain will benefit, and unrelated local businesses will benefit from increased household and business incomes (EPA,2010).

According to the Union Scientists increasing our use of renewable energy offers other important economic development benefits. The government can collect property and income taxes and other payments from renewable energy project owners. These revenues can help support vital public services, especially in rural communities where projects are often located.

Renewable energy can provide an affordable and consistent electricity supply across the country and solve the issue of serious power cuts. Total electricity generation in 2009 stood at 7,900 GWh, of which 53.3% or 4,303 GWh was produced from renewable sources. Electricity consumption per capita in 2009 stood at 1,022 kWh (REEEP,2012). Renewables can help stabilize power supply and energy prices in the future.

Renewable energy sources are more resilient than fossil fuels in times of recurring droughts and flooding extreme weather events. Solar PV is less prone to large scale failure because of Zimbabwe’s abundance of sunshine throughout the year.

Investment in locally available renewable energy generates more jobs, greater earnings, and higher output. Climate communicators say, “Renewable energy investment is paying off and those countries failing to embrace the transition are missing out. Countries are reaping the benefits of renewables, including home grown jobs, cleaner air, energy security and safer investments.”

IRENA Director-General Adnan Z. Amin mentions, “As many economies are still recovering from the global financial crisis, renewable energy offers an opportunity to grow economies, improve energy security, enhance energy access, and mitigate climate change,”.

According to IRENA, in 2014 an estimated 7.7 million people in the world worked directly or indirectly in the energy sector, with an additional 1.5 million in large-scale hydropower.Solar PV is the largest employer, with 2.5 million jobs.

As Zimbabwe’s average solar insolation stands at 5.7 kWh/ m2/day. The potential for renewable energy, especially from solar PV and solar water heaters, is enormous but thus far hasn’t been sufficiently exploited. Solar PV has a technical potential of over 300 MW, whilst only 1% of the technical potential for water heaters is being exploited (REEEP, 2012). All these statistics prove Zimbabwe can still rebuild its economy profitably through embracing the transition of a renewable energy era.

Another Mini-Hydro Plant For Manicaland Next Year

Another Mini-Hydro Plant For Manicaland Next Year

15 Jul 2015

hydroplant

NYANGANI Renewable Energy (NRE), an independent power producer (IPP) says it has started construction of its $7 million, 2.72 MW mini hydro plant in Manicaland which is expected to be complete by January 2016.

In an interview, managing director Ian Mckersie said the new mini hydro will add to the existing three stations known as Duru, Nyamhingura and Pungwe Hydro Power plants in the same province.

“We have now started constructing the new mini-hydro power station known as Pungwe C and we hope to commission it by January 2016,”he said.

Mckersie said the project will be completed at a cost of $7 million.

NRE was licensed by the Zimbabwe Energy Regulatory Authority (ZERA) early this year to construct, own, operate and maintain a 2,72 MW mini-hydro power known as Pungwe C Power Plant at Chiteme River in Manicaland Province.

According to ZERA about 18 IPPs have been licensed and to date, seven are now operational producing a total of around 103MW for own use and exportation to the national grid.

Of the 18, 11 are still at various stages of development and are expected to be wholly operational in the next three years. All the licensed IPPs have the capacity to generate about 5 365 MW.

Zimbabwe is currently producing about 1 200 MW against demand of 2 200 MW with the deficit however being complemented through imports.

Energy experts contend that the Southern African region requires massive investments in power sector and more independent power producers (IPPs) to ease electricity challenges currently bedeviling the region’s economic progression.

In Zimbabwe some of these projects include the coal fired China Africa Sunlight Energy operating as Gwayi Power Station (600 MW) based in Matabeleland North Province, hydro powered Manako Power (2, 5 MW) operating in Manicaland Province, Great Zimbabwe Hydro (5 MW) based in Masvingo Province, Geobase Gwanda Solar Plant (250 MW) based in Matabeleland South Province and the thermal Sengwa Power Station (1200MW) based in the Midlands Province among others. -FinX

Vandalism, theft cost ZESA $30m

Vandalism, theft cost ZESA $30m

Power lineGolden Sibanda Senior Business Reporter
POWER utility Zesa Holdings lost about $30 million worth of equipment due to vandalism and theft in the last 18 months, resulting in interruption of power supply in a country already grappling with power shortages.

Zimbabwe Electricity Transmission and Distribution Company managing director Engineer Julian Chinembiri said about $15 million equipment was vandalised. An equivalent value in potential revenue was also lost as a result.

“We lost about $10 million worth of equipment last year and so far we have lost about $5 million worth of equipment this year,” the ZETDC boss said, adding “the moment they vandalise infrastructure, supply of power to the industry and domestic customers is interrupted”.

The managing director made the remarks in an interview on the sidelines of a workshop to explore effective ways to stem the tide of theft and vandalism to power infrastructure.

Eng Chinembiri said a total of $10 million in potential revenue was lost last year and in the half-year to June half of that amount is believed to have been lost due to the interruptions caused by vandalism and theft.

“For example, we gave an idea (of estimated revenue lost). As a utility, we lost close to $10 million and if we compare with last year, it means, roughly we have lost close to $5 million in revenue from January to June,” he said.

The problem was most prevalent in power infrastructure such as transformers, where oil is drained and copper components stripped, overhead wire transmission lines, which are stolen and sold locally or exported.

This comes against the backdrop where the utility is battling to raise financial resources required to maintain transmission infrastructure and finance daily operations, as it is owed about $900 million by its customers.

ZETDC is due to present a new strategy targeting $80 million collections for the billion dollars owed by customers in unpaid power bills. He said theft and vandalism was seriously affecting supply to customers.

“We know that we are load-shedding, but each time power goes off our customers think that it is load-shedding and they see that power cut is prolonged. At the end of the day, they discover that its vandalised equipment. As such, this affects power supply to our customers,” he said.

Eng Chinembiri said the power tariff levied to customers did not provide for vandalism or theft of equipment, which sees the utility diverting funds for expansion and maintenance to replacing stolen equipment.

The discussions around ways and means to curb vandalism and theft of power infrastructure comes amid concerns about the extent to which the laws provided deterrent punishment on anyone caught tampering with equipment.

Head of legal services in the Prosecutor- General’s Office Mr Admire Munowenyu said challenges arise when incorrect laws are cited when compiling charges for prosecution, affecting chances for the maximum possible sentence.

“If the mandatory sentence is five years just for possession, the law should say so, I think if we do so we would have made more progress.”

This view was shared by Superintendent Sibangilizwe Mukwena who said maximum conviction was sometimes not secured due to reference to laws that did not prescribe most deterrent sentences to convicted criminals.

He said since January, police had handled 31 serious cases of vandalism and theft of power infrastructure and were doing a lot to deter, investigate and prevent recurrence of such in collaboration with other parties.

Chief magistrate Mishrod Guvamombe said the courts of law followed due process and justice delivery process and required sufficient evidence during prosecution and if that is availed conviction could be secured.

Solar Expo set for Bulawayo

Solar Expo set for Bulawayo

Brighton Gumbo Business Reporter
BULAWAYO will host an inaugural expo on solar energy this weekend to deliberate on the development of renewable energy opportunities in solar power.

The expo is being organised by SNV Netherlands, a non-governmental organisation in partnership with council, solar companies and the provincial leadership.

More than 25 major solar companies are expected to participate at the expo.

SNV Head of renewable energy sector Chandi Makuyana said: “The solar fairs will create marketing spaces for SNV trained youth entrepreneurs in partnership with the central distributors to engage the market and showcase the wide variety of holistic, quality solar products and solutions that are available and affordable”.

He said their initiative has received support from big corporates such as Total Zimbabwe, Solar Shack, Samansco, Gemwitts and GreenDot.

Makuyana revealed that Total Zimbabwe, in partnership with SNV, have already trained 360 youth entrepreneurs drawn from rural and peri-urban communities in marketing of its new brand of lights and lanterns.

A financial advisory support has been set up for the project by different financial institutions such as FBC through its micro plan programme.

The expo will explain how customers who wish to install solar home systems can access finance as part of awareness campaigns under the theme, “Solar Kumusha/ISolar Ekhaya’ and ‘Zvirikufaya ne/Ziyakhipha nge solar’.

“We’ve indeed seen the lives of communities in rural areas transformed by the use of solar products and every rural household deserves to have solar solutions for power and lights,” said Makuyana.

He said similar expos will be held in Lupane, Karoi, Mutare, Mt Darwin, Masvingo and Mutoko.

SNV Zimbabwe has been in Zimbabwe since 1983 contributing to poverty reduction and economic growth in line with the country’s medium-term plan and the global millennium development goals.

$3bn Lusulu power plant construction expected to begin next year

$3bn Lusulu power plant construction expected to begin next year

THE construction of independent power producer, Pan-African Energy Resources (PER)’s proposed 2,000 MW Lusulu Coal Power Plant in Binga should commence in the first half of 2016 if the Zimbabwe Energy Regulatory Authority (Zera) approves the company’s proposedamendments to its generation licence.

The investor is seeking to have its licence amended after failing to initiate its proposed $3 billion project within the set timelines.

PER Lusulu Power was granted a generation licence in October 2010, with one of the key conditions of being given the licence being that the independent power producer should have commenced work on site within one year of receiving the licence.

However, since the issuance of the licence in the last quarter of 2010, the proposed 2,000 MW coal fired-power plant is yet to get off the ground.

Indications from the company are that it now finally wants to commence the process of establishing the power plant by submitting a Grid Impact Assessment study from the Zimbabwe Electricity Transmission and Distribution Company (ZETDC) by the end of October this year.

PER Lusulu Power has finally engaged investors willing to fund the project.

In December last year, Zera chief executive Gloria Magombo — while acknowledging the project had overrun the initial implementation plan by two years — noted some progress the company had achieved.

“A preliminary feasibility study report has been submitted and a new lead financier has been identified. The promoter has identified various contracting companies relevant to the project and MoUs have been signed,” said Magombo at the time.

In a statement last week Zera said it had “received an application for amendment of generation Licence number GC0016 issued on 26th October, 2010 to PER Group Ventures (Pvt) Ltd trading as PER Lusulu Power to construct, own, operate and maintain a 2,000MW thermal power station for the purpose of generation and supply of electricity in Zimbabwe. PER Lusulu is seeking to amend . . . conditions of the licence, which are linked to the implementation time frame of the project”.

The application for amendment of the licence by PER Lusulu is being done in terms of Section 49 (1) (b) of the Electricity Act (Chapter 13:19) of 2009.

In terms of the new conditions requested by the IPP, Phase I of the project (that is, construction of 500MW should begin 30 days after all the project and financing agreements have been signed and all the required conditions contained in them have been met, whose date has been provisionally fixed as March 31, 2016.

According to PER Lusulu — to the extent that the licence amendments are approved by Zera — the four phase construction project will now be expected to be completed and fully operational by the second half of 2021.

The PER Lusulu Power station, to be sited on the southern side of Lake Kariba, is within Binga’s Lusulu coalfields, with an estimated resource of 1.2 billion tonnes.

Earlier in March, Engineer Magombo told the Parliamentary Portfolio Committee on Mines and Energy larger IPPs — whose capital requirements are huge — were struggling to get off the ground.

She hastened to add that some IPPs had since approached Zera requesting for changes in the parameters of their licences due to “circumstances beyond their control”.

According to data provided by Zera, four mini-hydro projects by Nyangani Renewable Energy (Pvt) Ltd are currently operational, namely Duru, Pungwe A, Pungwe B and Nyamingura with total output of 21MW.

Other operational IPPs include Chisumbanje which currently supplies up to 4MW to the national grid, and Hippo Valley and Triangle Estates co-generation at a total 78MW. — BH24

The Zambezi River Authority has engaged Ernst & Young as financial and legal transaction advisors for the development of the Batoka Gorge Hydro Electric Scheme.

Addressing an inception workshop in Livingstone recently, ZRA chief executive Engineer Munyaradzi Munodawafa said the Financial and Legal Transaction Advisory Services Contract sat on the critical path of the Batoka Gorge Hydro Electric Scheme development plan as the consultant is expected to analyse the different transaction structures, including options for Public Private Partnerships, or Build, Operate, Transfer or Engineering Procurement and Construction.

“The advisors would recommend the most optimum and bankable structure that takes into consideration the prevailing market conditions, priorities of the stakeholders involved and the technical parameters and development schedule resulting from the updated feasibility study

The advisory services team comprises international experts in finance and legal services.

Participants were drawn from the Batoka Gorge Hydro Electric Scheme Project Steering Committee and the Project Management Unit appointed by the Governments of Zambia and Zimbabwe.

The financial and legal advisors component completes the list of the vital project preparatory works which have taken three years to be concluded.

Eng Munodawafa commended the World Bank for financing the preparatory studies of the Batoka Gorge Hydro Electric Scheme through a grant under the Co-operation in International Waters in Africa.

According to ZRA, these preparatory studies consist of: updating of the engineering feasibility studies, updating of environmental and social impact assessment studies as well as the financial and legal transaction advisory services.

Eng Munyaradzi also assured the stakeholders and the consultants that the two governments were committed to making timely decisions necessary for the services to be completed as planned.

“The Governments of Zambia and Zimbabwe are aware that the success and speedy implementation of the assignment will depend on decisions to be made by the two Governments.”

Ernst & Young presented the scope of their work in the infrastructure and project finance for the Batoka Gorge Hydro Electric Scheme which included the relevant steps required from their advisory services.

They clarified the role of project finance in infrastructure development and the requirement for due diligence in such processes for effective implementation of the project.

It is against this background that the team brings on board technical, financial as well as legal expertise for carrying out the exercise.

Eng Munodawafa urged the three consultants Studio Pietrangeli, Environmental Resource Management and Ernst & Young to work closely as their processes and outputs were interrelated and the results thereof are critical to effective and timeous execution of the Batoka Hydro Electric Scheme.

Zim power projects on course

EXPANSION of Kariba South Power Station to add an additional 300MW to the national grid is on schedule, with the project forecast for completion within set timeframes.

The project dovetails with regional pursuits meant to pull Sadc out of the electricity deficit position it is presently in.

Indications are that by 2018 the power supply situation in Zimbabwe and the region would have improved significantly.

Zimbabwe Power Company MD Engineer Noah Gwariro told The Sunday Mail Business that although there were some hiccups, the project would be concluded by December 2017 as planned.

ZPC is a unit of the Zimbabwe Electricity Supply Authority.

The injection of 300MW into the local power pool will help alleviate shortages blighting domestic and industrial users.

Already, drilling of four of the six access tunnels has been completed, with the rest on course for completion in the “next few weeks”.

“Drilling and blasting is in progress to carve out the underground powerhouse and the head race tunnels which will direct water from the lake to the turbines.

“We are also working on the excavation of the intake and outlet areas. Manufacturing and procurement of the electromechanical equipment has started in China, and these will monitored and reviewed until completion.

“We are on schedule and we anticipate that the first generation unit will be commissioned in December 2017, and the second in March 2018,” said Eng Gwariro.

He said they had put in place a recovery plan for the two remaining access tunnels.

The project is being undertaken by Sino Hydro Corporation largely via a US$533 million China Exim Bank loan. Sino Hydro owns about 70 percent of China’s thermal power stations.

On completion, Kariba South Power Station’s generation capacity will grow from of 750MW to 1 050MW.

There are, however, lingering concerns over the project cost after Sino Hydro quoted Zambia’s government US$421,1 million for a bigger project – the Kariba North Bank project in Siavonga to generate 360MW.

Kariba North Bank extension began in 2008 and was completed on August 20, 2014 with the commissioning of the second and final 180MW generator.

Meanwhile, Eng Gwariro said expansion of Hwange Thermal Power Station had also started and preliminary geotechnical and topographical studies were complete.

“Upon finalisation of financial closure, it is expected that the first unit will be commissioned after 36 months,” he said.

It is estimated that expansion of the thermal power plant, which will feed 600MW to the grid, will gobble more than US$1,1 billion. Government’s power projects will augment similar efforts across Sadc.

According to Southern African Power Pool (SAPP), a grouping of power utilities, Zimbabwe has an installed capacity of 2 045MW. However, as at last Thursday, the country was generating 1 349MW, with Kariba and Hwange producing a combined 1 270MW.

The two have installed capacity of 1 670MW. On completion, the country’s two marquee projects will bring an additional 900MW to the national grid and catapult installed generation capacity to 2 945MW.

The Zimbabwe Energy Regulatory Authority has licensed 22 power projects, 19 of them private and three State-owned. Only four private producers, all in the Eastern Highlands are feeding the national power grid. These are Duru (2,2MW), Nyamingura (1,1MW), Pungwe A (2,75MW) and Chisumbanje Power Plant (8MW).

Triangle Limited, which has an installed capacity of 45MW and Hippo Valley (33MW), are generating power for own consumption using bagasse.

Chisumbanje is consuming about 4MW at its ethanol project.

Pungwe B is expected to be commissioned this year and will contribute 15MW to the grid.

Eng Gwariro also said the tender for the 30MW Gairezi hydroelectric project, also in the Eastern Highlands, closed on June 9, 2015; while adjudication of the commercial envelope for 300MW solar projects concluded and documents were with the State Procurement Board.

The Zimbabwe Power Company, a Zesa subsidiary, is also fulfilling conditions for funding of Harare Power Station repowering project while tenders for Bulawayo and Munyati power stations ran until June 16, 2015.

A revised project schedule released by Zera last Wednesday showed that Pan-African Energy Resource, the French developers of the 2 000MW coal-fired plant in Binga, plan to commission the first phase of the project by mid-2019.

Overall, Sadc has reduced the power deficit by 3 000MW over the last year and is expected to add another 27 000MW by 2018 as Zimbabwe, Zambia, Botswana, DRC, Angola and South Africa ramp up generation.

The region has peak demand of 54 000MW against generation capacity of 51 000 MW.

Since the last major electricity crisis in the region in 2008, power demand has increased and power projects generating 1 100MW are commissioned annually. But until 2018, load shedding is expected to continue.

South Africa is enduring electricity blackouts but has some five projects targeted for commissioning this year, producing an additional 1 828MW.

Coal will contribute the largest share of the new generation capacity in South Africa, with the coal-fired Medupi Power Station expected to have additional capacity of 738MW by the end of this year. The country is also expected to contribute 435MW from co-generation capacity between national power utility Eskom and an IPP.

Botswana recently announced it would load shed this winter. That country has peak demand of 600MW and relies on imports from Mozambique, Namibia, South Africa and Zambia.

Shumba Coal, a Botswana company, announced Tuesday that it plans to develop a solar power station to generate up to 200MW of electricity.

The Zambia Power Rehabilitation Project has so far rehabilitated and upgraded the Kafue Gorge Power Station from 900MW to 990MW, reinstated the Victoria Falls Power Station to its full generating capacity of 108MW and up-rated the Kariba North Bank power station from 600MW to 720MW.

Kariba North Bank Extension (360MW) was completed last year while the Kafue Gorge Lower Hydro Project (750MW) is set for completion in 2017. Itezhi-Tezhi Hydro Power Project (120MW) was completed in February 2015.

Construction of the 14,8MW Lunzua hydro power plant has also been completed at a cost of US$51,6 million.

An estimated 80 percent of Malawians live in rural areas and the bulk of them use paraffin burners locally known as “kaliboyi” or “nyale” for lighting due to the country’s low power capacity.

Malawi has installed capacity of 351MW against demand of 360MW.

Estimates show country will require not less than 1 000MW by 2018.

Angola plans to spend US$23,3 billion on 65 water and electricity projects over the next two years, while the DRC is due to add 430MW this year.

Eskom eyes 2,400MW Sengwa power project

Eskom eyes 2,400MW Sengwa power project

Prosper Ndlovu Business Editor
SOUTH African power utility, Eskom, has expressed interest in bankrolling implementation of the long awaited 2,400MW Sengwa Power Project, which has been in limbo for the past two decades.

Given the widening power supply gap in the region, experts have urged regional joint venture investments to boost power production — a key ingredient for investment and economic growth.

The project, then named Gokwe North Power Station, was mooted in the 1990s jointly by Zesa, the National Power of the United Kingdom and Rio Zim.

It was developed to feasibility stage but has failed to move beyond that stage.

The government, under the then Zimbabwe Electricity Regulatory Commission, granted Rio Zimbabwe Limited an independent producer licence in 2010 to establish a power plant in the coal-rich Sengwa area in Gokwe North.

Nothing has happened to date.

Parliamentarians expressed disquiet over the project last week when they asked Energy and Power Development Minister Samuel Undenge to clarify the status of the project and the duration of validity of the licence.

“Currently, Sengwa Power Station is negotiating for possible off-take agreements anchored by Eskom of South Africa and other regional utilities, to guarantee bankability of the project,” Minister Undenge responded.

“It’s important to note that due to its size, the project can’t be supported by the Zimbabwe market alone and it requires other regional markets as off-takers to make it bankable. The current efforts to raise funds are based on the original 1,200MW capacity the Gokwe North Plant had envisaged.”

RioZim, which has announced plans to exit Zimbabwe by selling its stake in Murowa Diamonds and Sengwa coalfields, has said it needed about $2.1 billion to build power plants that would produce up to 1,400 megawatts of electricity.

The company’s chief executive officer Noah Matimba recently said they were in talks with regional power trading firm, Southern African Power Pool and big Zimbabwean electricity users about an agreement to sell electricity to them.

“We do need a power purchase agreement in order that we can attract investors or attract those lenders that can give us (money),” Matimba said.

“We’ve signed an MoU with the Southern African Power Pool in the hope that we can begin to discuss a power purchase agreement with them and be able to create the necessary demand to attract investors.”

The power station project is capable of generating up to 2,000MW of power, almost as much as Zimbabwe’s demand. The proposed project envisages the construction of a number of smaller power plants over the next ten years.

The minister said the government was disturbed by the tendency by some operators who hold on to their licences for speculative purposes.

“To avoid this, the regulator, Zera, is now issuing conditional licences outlining the milestones to be accomplished to the point of project commissioning,” he said.

Minister Undenge warned that if the current efforts by Sengwa Power Company, which are expected to be finalised before end of 2015, fail to materialise, “Zera may be left with no option but to cancel the licence as the promoter would have failed to fulfil the licence conditions”.

He said the regulator will continue reviewing all licensed IPPs to ensure timely implementation of proposed projects.

ZESA to import Zambian power

ZESA to import Zambian power

Lunsemfwa-Diversion-DamMartin Kadzere Senior Business Reporter
ZESA Holdings is in talks with Lunsemfwa Hydro Power Company of Zambia to import electricity to boost domestic supply, officials from both companies said yesterday.

Zimbabwe’s power plants produce an average 1 200 megawatts, about half of its peak demand. The country is minimising power shortages through imports from the region. A delegation from Lunsemfwa is in Zimbabwe for negotiations, which, if successfully concluded would see Zimbabwe importing 50 megawatts from Zambia, Zesa chief executive Engineer Josh Chifamba said.

“This is part of our efforts to boost local supply through importing electricity from other sources in the region and we are negotiating for a power purchase agreement with Lunsemfwa,” Eng Chifamba told The Herald Business, adding that this was critical in terms of supporting Zim-Asset, the country’s economic blueprint.

Lunsemfwa Hydro is the first independent power producer in Zambia. It operates two hydropower plants with a total installed capacity of 56MW. LHPC is currently undertaking feasibility studies and has a strategic plan to increase the installed capacity to 500MW by 2020. LHPC is a subsidiary of Agua Imara, an SN Power Group company.

Eng Chifamba said he was confident negotiations would be concluded by mid next year.

Lunsemfwa Hydro chief executive Mr Katai Kachasa said if the current negotiations were successfully concluded, there was potential to gradually increase electricity supplies to Zimbabwe since it is planning to increase its generation capacity.

“We will soon be embarking on projects to increase our generation capacity,” said Mr Kachasa.

Eng Chifamba said the power purchase agreement would be on a pre-paid basis and Zesa would “continuously move all our customers” to pre-paid electricity meters to generate enough income to meet its import obligations. About 42 percent of Zesa’s income comes from customers on pre-paid meters and plans to grow it to 70 percent in first half of 2016.

“We need to get power challenges out of our way by growing prepaid revenue to 70 percent (of Zesa’s total revenue). This will not only improve revenue inflows, but will also enhance creditworthiness and capacity of the company to reinvest in critical capital projects,” said Eng Chifamba.

He added that Zesa recently reached an agreement with ferrochrome producers to go on prepaid metres. Zesa has also gone on prepaid arrangement for power imports from Mozambique where it is purchasing about 50 megawatts. As such, economic analysts say it was time Zesa grow its prepaid revenue considering that it is also paying for imports in advance.

“Despite increased revenues inflows from domestic customers, it is critical that all customers, domestic and commercial are put on prepaid metres. This will help guarantee imports while at the same time ensure that the company generates enough revenue for its capital projects as well as putting the company in a stronger position to attract debt capital from local, regional and international markets,” said one analyst.

On the back of prepaid income, Eng Chifamba said the power utility has successfully raised substantial money from a regional financial institution against its debtors’ book.

Ntabazinduna to get power station

Ntabazinduna to get power station

 

AN independent power producer, Yellow Africa (Pvt) Ltd, has been awarded an operating licence by Zimbabwe Energy Regulatory Authority (Zera) to establish a 100 megawatt (MW) solar plant in Ntabazinduna, Matabeleland North province.

BY NQOBILE BHEBHE

The proposed plant will generate electricity using solar radiation at Ntabazinduna or Mbembesi communal lands under Umguza Rural District Council.

According to a notice, the licence was issued in May and Yellow Africa could supply power to any distribution network.

“The generation licence is hereby granted to Yellow Africa (Pvt) Ltd (the licensee) in terms of Section 42 of the Act to construct, own, operate and maintain Ntabazinduna Solar Power Station for purposes of generation and supply of electricity,” the regulatory authority said.

“Subject to the Act and the terms and conditions of its licence, the holder of this generation licence may supply to any transmission distribution or supply licensee who purchases electricity for resale and with the approval of the Zimbabwe Energy Regulatory Authority (hereinafter referred to as the Authority) to any one or more consumers.”

The government has over the years licensed scores of independent renewable power producers, some of which were already operational while others were working on starting up.

Three small hydro plants presently operational were Nyamigura (1,1MW), Pungwe A (2,7MW) Duru (2,2MW) and Pungwe B (15MW) in Manicaland province.

The Great Zimbabwe Hydro (5MW), Kupinga Station (1,5MW) in Chipinge, Osborne Dam plant (2,5MW) and Rusitu Plant were set to open soon.

On biomass energy, Tongaat Hullet is operating Triangle Sugar Mill (45MW) and Chiredzi Sugar Mill (33MW).

In the pipeline would be the exploitation of massive gas reserves in Lupane and plans to set up a gas-fired power plant to contribute 300MW to the national grid.

SADC In Energy Crisis

SADC In Energy Crisis

Some of the SADC head of states

WITH climate change posing one of the major threats to humanity’s shared interests in southern Africa, the region has been plunged into a dilemma as to how it could wiggle out of an impending energy crisis as it seeks to address the global warming phenomenon.
Nations in the Southern African Development Community (SADC) depend on fossil fuels such as oil and coal that are being condemned, globally, for their high pollution levels.
They are also reliant on hydro-electricity, which is under threat from drying rivers as the regional climate gets warmer.
While hydro-electricity is a clean and renewable source of energy, the increasingly irregular rainfall patterns have made river water no longer a sustainable source of energy.
And already feeling the heat are Zambia and Zimbabwe. The two countries share part of the Zambezi River and exclusively own the massive water body, Lake Kariba, which is a critical source of power for the two countries.
The Zambezi River Authority, responsible for the management of the basin from which the two neighbours draw water for hydro-electricity, has been forced to reduce water allocation for electricity generation from 45 billion cubic metres per annum to 33 billion cubic metres due to dwindling supplies as the mighty Zambezi River’s major tributaries, upstream of Kariba, dry up.
The poor inflows have triggered a record drop in the 280km-long lake’s level following a prolonged drought in southern Africa, resulting in a 400 megawatt (MW) plunge in electricity supplies from Kariba Power Station.
Zambia has already cut generation by 300MW and has warned its citizens that this could further go down by as much as 600MW as the Kariba water situation gets worse in the next months.
By August the situation will have worsened when most of Zambezi River’s tributaries run completely dry.
Regional economic powerhouse, South Africa, has not been spared by the power crisis.
Thus, coal and oil, roundly condemned for high carbon emission which is a major catalyst for warming global temperatures, are now the only available alternatives.
With projections of a future global economy likely to consume more energy, especially with the rising energy demand by developing countries, the effects of fossil fuels on climate change is increasingly becoming a major talking point among environmentalists, energy experts and even governments.
Never before has the costs and consequences of climate change become so topical an issue in the underdeveloped world, where the delicate adjustment to the use of cleaner sources of energy, other than hydro-electricity, has never been an issue.
With the developed world fast promoting renewable energy from water, wind, waves, solar and biomass, developing countries, such as those in SADC, are now caught up in a complex energy crisis because they are unable to exploit the new sources of energy.
But many argue that southern Africa is capable of harnessing these clean energy sources and gradually phase out fossils.
What lacks, they say, is political will.
“For the first time in history we face an energy crisis not because we might run out of energy, but because we are using it in the wrong way. Up to now the energy industry was judged by two metrics: Its contribution to energy security and the cost of energy delivered to the consumer. To this we must now add a third: Its success in reducing the emission of ecologically harmful gases, chiefly carbon dioxide, into the atmosphere,” said energy expert Panganai Sithole, director of the Zimbabwe Energy Council.
“We need to address this crisis in two dimensions, demand management of power and ensuring energy efficiency, through a well coordinated energy policy. For example, it has been established that in Zimbabwe, 40 percent of domestic power consumption is by geysers that can be easily replaced by solar water heaters, although mainly rich families can afford it.
“In the energy policy, we can simply make it mandatory that all low density houses should have solar water heaters and help them by removing import duty on the alternative energy sources. It does not take any money for government to implement this. Imagine the amount of power we could save with this policy,” he added, while encouraging the Zimbabwe government to court investments in renewable energy and allow independent power producers the opportunity to easily get into the power production business.
“We are not even harnessing solar as a source of power despite the amount of sun we get. There has been endless talk of a solar power plant in Gwanda but we haven’t seen its progress years after it was launched. Gas, for example, attracts serious investment everywhere in the world. Mozambique is realising the benefit of its investment policies and we are importing supplementary power from there,” Sithole said.
However, other energy experts think differently, arguing that the environmental concerns around power generation were being pushed by rich countries at the expense of developing countries.
Founder of Harare-based energy firm, Energy and Information Logistics, Francis Masawi, noted: “Rich countries complain about it yet they managed to achieve their development using coal and oil and they can now afford the expensive alternative sources.
“True, solar is available but the technology is not sufficient here. We must be allowed to utilise the resources we have and when we have developed to their levels, we can start talking the same language and start thinking about the expensive clean energy they are talking about.”
The great divide among imperative dynamic forces behind climate alleviation is very precarious and threatens the collective global climate action around the world.
And despite what many climate action groups advocate for, energy experts looking at capacities of all technologies seem not to see a realistic possibility for a rapid shift into 100 percent renewable energy any time soon.
They have several scenarios for the future of energy production in light of climate change mitigation, and they all include increasing nuclear power as a renewable energy source, something which has already sharply divided opinion as some feel the answer to climate change is not nuclear power.
There are worries peculiar to uranium such as its radiation problems and its capacity to make nuclear weapons that make it a major source of global conflict.

Zim Faces Unprecedented Power Crisis

Zim Faces Unprecedented Power Crisis
Phillimon Mhlanga 4 Jun 2015
Hwange-Thermal-Power-Plant

Zimbabwe has been experiencing crippling power shortages for a long time now because available generation of about 1 000MW has been unable to meet demand of over 2 000MW.

ZIMBABWE plunged into an unprecedented electricity supply crisis this week after the country’s power supply company intensified load-shedding due to worsening generation capacity, caused in part by a technical fault at Hwange Power Station.
Consequently, the country will endure its darkest winter season in history, as it would be unable to augment domestic electricity supplies with imports.
To worsen matters, ZESA Holdings is already faced with a 400 megawatts (MW) plunge in generation capacity at Kariba Power Station occasioned by the fall in water supplies in Kariba Dam.
The power utility this week warned “customers countrywide” to brace for “an increase in load shedding outside the publicised schedule due to a technical fault at Hwange Power Station”.
Although ZESA, an integrated power generation and distribution company, said it was working to restore generation at the plant, this is not the first time problems have occurred at Hwange Power Station, whose plant is aged and desperate for refurbishment.
A source indicated that supplies would be assured, but not guaranteed, for major referral hospitals, water and sewer installations, national security establishments, airports and broadcasting stations and central business districts.
“The rest of the country will receive power for between seven and 17 hours a day,” the source said.
Even before ZESA’s warning, households and industries have been subjected to load shedding of between three to five hours daily.
The vulnerable and constrained power generation system is, however, likely to lead to extended periods of programmed blackouts triggered by insufficient electricity generation.
But there were fears that unexpected disruptions caused by plant breakdowns due to old age would also worsen during this period.
Two weeks ago, the Financial Gazette reported that water levels in Kariba Dam had dropped to record lows following a prolonged drought in southern Africa.
As a result, electricity supplies from Kariba Power Station, Zimbabwe’s biggest electricity generator, are likely to plunge by 400MW.
Zambia, which shares the same water resource for its electricity production, has already cut generation by 300MW and warned last week that this could further go down by as much as 600MW due to the water situation in Kariba Dam.
The Zambezi River Authority, responsible for the management of water in the Zambezi River basin from which both Zimbabwe and Zambia draw their water for hydroelectricity, has been forced to reduce water allocation for electricity generation from 45 billion cubic metres per annum to 33 billion cubic metres due to dwindling water supplies.
The situation is likely to get worse after this winter season as rivers feeding into the Zambezi River, upstream of Kariba Dam, dry around August or September.
Zimbabwe has been experiencing crippling power shortages for a long time now because available generation of about 1 000MW has been unable to meet demand of over 2 000MW.
Industry players and lobby groups warned the situation would have grave consequences on industry, already grappling with low capacity utilisation due to power shortages, among other problems.
A report by the Chamber of Mines said mines were already “battling with reliability of electricity supply”.
It said power outages caused by faults and load shedding had resulted in a loss of production time by as much as 10 percent.
There was no immediate comment from mining industry executives over the threat of increased power outages, but analysts contend this would be dire.
“Power is one of the many infrastructural utilities which are supposed to play an enabling role in the economy,” said Dephine Mazambani-Mutafera, chief economist at the Confederation of Zimbabwe Industries (CZI).
She said the 2014 CZI Manufacturing Sector Survey had highlighted that electricity shortages were on top of five identified constraints to capacity utilisation in industry.
“Power cuts and shortages were recorded as the most problematic infrastructure factors by companies. Eight percent of respondents indicated they had to reduce the number of working hours due to power cuts,” said Mazambani-Mutafera.
“Given the production processes, sometimes it’s difficult to stop a process when it has commenced hence companies have a backup system which can be in the form of a generator. This is an expensive system to maintain compared to electricity.”
But she said they had observed that many companies did not have power supply backup, resulting in increased redundancies and production decline.
“But earnings per worker do not decline as our wages and salaries are not related to productivity. A company will have to incur labour costs regardless of not producing,” she said.
Mazambani-Mutafera said foreign investors were shunning Zimbabwe because of the electricity supply situation.
“Investors look at the assurance that they will have sufficient reliable power supply. So, given the anticipated crisis, we expect few investors to consider Zimbabwe as an investment destination,” she said.
The recovery of the productive sectors, such as manufacturing, agriculture, mining and tourism, which government hopes to underpin revival of the country’s comatose economy, is likely to suffer a huge blow due to the worsening power supply situation, she said.
thers contended that the cost of load shedding on the environment is also too ghastly to contemplate at a time when the country is losing 300 000 hectares of forests to both domestic and industrial users desperate for power.
Unstable power supplies are causing companies to incur heavy losses as some processes are interrupted thereby affecting the quality of products.
Some processes are also delayed or aborted resulting in failure to meet deadlines and targets for many companies.
The situation is invariably scuttling away potential investors.
The prevailing electricity shortages will see the country revising downwards its projected 3,2 percent economic growth and more of the suffering industries will shut down units, exacerbating the already unstable unemployment situation.

Thumbs-up for Mutirikwi mini-hydro power plant

Thumbs-up for Mutirikwi mini-hydro power plant

George Maponga Masvingo Bureau
Work on a $13,5 million mini-hydro power plant on Lake Mutirikwi Dam is set to begin soon after Masvingo Rural District Council gave the green light.

Great Zimbabwe Hydro Power Company – a joint venture between a Zimbabwean firm ZOL and New Planet of South Africa -recently got permission from the Masvingo RDC to go ahead with the project that will generate five megawatts upon completion.

Masvingo RDC acting chief executive Mr Martin Mubviro last week said they were jointly managing the power generation project with the Zimbabwe National Water Authority (Zinwa).

Mr Mubviro said his council passed a resolution giving Great Zimbabwe Power Company permission to start work on the power plant.

“Zinwa will deal with the remaining issues that need to be sorted out before work on the plant can begin because we recently established that the land where the investors want to build their plant belongs to the water regulatory authority,’’ he said.

“As Masvingo RDC, we finished our part when we gave Great Zimbabwe Power Company permission to start work and we hope the project will kick off soon once the investors have reached an agreement with Zinwa.

Great Zimbabwe Power Company initially applied to the Masvingo RDC for one hectare of land at Lake Mutirikwi to build their power plant, but the firm has since been directed to forward the application to Zinwa, which owns the land.

Power produced at the plant will be fed into the national grid and is expected to ease electricity shortages in Masvi- ngo.

The project will be done in phases and will take up to two years to complete.

This will be the second plant in Masvingo, with a similar project being planned at Tokwe-Mukosi Dam in Chivi South to generate about 15 megawatts.

Reprieve for wheat farmers

Reprieve for wheat farmers

 

Zimbabwe Electricity Transmission and Distribution Company (ZETDC) will give additional support to wheat farmers this winter to ensure a successful season, the power utility has said.

BY SILENCE CHARUMBIRA

ZETDC said it would channel additional support to the farmers and a number of other key institutions like hospitals, national security establishments, airports and broadcasting stations and major central business districts.

“In addition, winter wheat irrigation will receive additional support in the 2015 season in order to ensure the success of the crop,” said the power utility in a statement on Thursday.

Farmers yesterday welcomed the move saying they had engaged the power utility last season and it delivered.

Zimbabwe Commercial Farmers’ Union president Wonder Chabikwa said there were challenges at the beginning of May but the problems at Hwange had since been rectified.

“We clustered our wheat farming areas and came up with a plan to have four days of uninterrupted supply per week. Last year they agreed to our request and we are confident they will do the same this year,” said Chabikwa.

He said planting was underway and indications from millers were that they needed up to 90 000 metric tonnes of the grain this season.
Farmer Godfrey Chingwe said GMB should increase the producer price of wheat to at least $580 per tonne to ensure viability.

“It will help us to pay for our overheads and acquire inputs for the following season. The other issue is it is important that the GMB pays farmers on time to ensure viability.

That way we will not have to wait to produce more crops as the finances will be readily available,” he said.

Winter power demand triggers increased outages

THE Zimbabwe Electricity Transmission and Distribution Company (ZETDC) has warned consumers of increased power cuts of up to nine hours twice per day during the winter season after demand for electricity rose to 1,800 MW against average output of 1,300MW.The power utility has crafted a schedule in which consumers countrywide will be put under load shedding at morning peak (5AM to 1PM) and evening peak (1PM to 10PM).

It, however, gave reprieve to essential services that include major referral hospitals, water and sewer installations, national security establishments, major airports and broadcasting stations and central business districts.

In the load shedding schedule issued yesterday, ZETDC pledged additional support to winter wheat irrigation for the 2015 season.

Zimbabwe’s seasonal peak power demand occurs during the winter months of June and July with the power utility saying it expects maximum demand to average 1,800MW.

ZETDC would not rule out interruption of supplies due to suppressed generation capacity by local plants and general deficit in the entire region.

“To this end, Zesa is putting in place measures to boost power generation and reduce consumption in order to minimise load shedding. All non-essential loads and appliances should be switched off at all times. Non-essential lights and office equipment should be switched off overnight. Accordingly load shedding will be carried out . . . consumers are being called upon to play their part in reducing demand by using the available power sparingly,” said ZETDC.

As of Thursday, Zimbabwe Power Company (ZPC) was producing 1,301MW, with the hydroelectric Kariba Power Station generating 662MW against an installed capacity of 750MW while Hwange thermal power station was producing 546MW against installed capacity of 920MW.

The utility’s small thermal power stations — Bulawayo, Harare and Munyati — are producing 35MW, 30MW and 28MW, respectively, against installed capacity of 75MW, 90MW and 100MW.

Zimbabwe also imports power from Hydro Caborra Bassa of Mozambique but supply remains too low to meet demand.

Of late, winter wheat farming has been hampered by intermittent and expensive power supplies to the farms and lack of subsidies from government to support wheat farming.

The Zimbabwe Commercial Farmers’ Union president, Wonder Chabikwa, said due to lack of subsidies on electricity for winter wheat farming, the farmers were paying 0,166 cents per kilowatt hour, a figure that he said was uncompetitive compared to 0,004 cents per Kw/h paid by consumers in other countries in the region such as Zambia.

Zimbabwe, which requires between 200,000 tonnes and 350,000 tonnes of wheat annually has of late been forced to import the crop due to low production.

New Hwange power plant takes shape

New Hwange power plant takes shape

 

INDEPENDENT power producer, Co-Ash Resources, is undertaking an environment assessment in Matabeleland North Province ahead of the construction of a thermal power plant in Hwange.

BY NQOBANI NDLOVU

Co-Ash Resources plans to set up a 250-megawatt (MW) waste coal-fired thermal plant that will have a double role of cleaning up the environment as well as supplying electricity.

The independent power producer said the 250MW integrated gasification combined cycle (IGCC) will be expanded to one gigawatt (GW) in 10 years.

An IGCC is a technology that uses a gasifier to turn coal and other carbon-based fuels into electricity.

“The main objective of the project is to construct a combined cycle environmentally friendly, highly efficient advanced plasma- fired thermal power plant that will supply significant amount of power to Zimbabwe utilising waste coal fires that have been and are a continuous environmental hazard in the coal mining operations in the Hwange district,” a notice of the environmental and social impact assessment read in part.

“The project, however, falls in volume six of the Environmental Impact Assessment guidelines of Zimbabwe. Volume six covers all projects relating to the energy sector in which the thermal power plant falls.

“In compliance with the Environmental Management Act (Chapter 20:27), Co-Ash resources is required to prepare an environmental and social impact assessment report for the said project.”

The country faces electricity shortages as Zesa Holdings is currently generating just over 1 000MW of the 2 200MW national requirement, resulting in incessant power cuts.

Although Zimbabwe Energy Regulatory Authority has licensed over 15 independent power producers, very few have implemented projects that are actually feeding into the electricity national grid to eliminate energy shortages.

Minister Undenge explains power cuts

Minister Undenge explains power cuts

Electricity cuts affecting many parts of Zimbabwe are being caused by technical faults in power generation plants across the Southern Africa region, Energy and Power Development Minister Dr Samuel Undenge has explained.

 

Dr Undenge told The Sunday Mail that due to its central geographical location, Zimbabwe was the hardest hit since the electricity interruptions were emanating from Zambia, Mozambique and South Africa.

“Our grid system is connected . . . in other words we are connected to Zambia, Malawi, South Africa, Botswana and all the electricity traffic passes through Zimbabwe because we are at the centre.

“Our six units at Kariba and four units at Hwange power station were down and this emanated from the Zambia’s Copperbelt. They had a loss of 600MW.

“So, if there is a severe power loss like the one that happened in Zambia, this will automatically affect power distribution in Zimbabwe. The recent one that happened a week ago, again the source was external; it originated from Mozambique. There was a fault at Hydro Carbora Bassa; there was a loss of load, resulting in an automatic shut down.

“Zimbabwe also encountered two power systems disturbances from South Africa and it resulted disconnection of the rest of our network save for Bulawayo Metropolitan province.

“Electricity generation at Hwange Power Station has been restored and as at today, (Friday) 397MW are generated from four units with the other remaining two units expected to be back soon.”

National energy demand stands at about 2 200MW during peak hours against installed generation capacity of 1 400MW.

Out of 1 400MW, Zesa exports 224MW to NamPower and Snel, the power utilities of Namibia and the DRC, respectively.

Like any other Sadc country, Zimbabwe is experiencing severe power shortages due to increased demand against depressed electricity generation.

Zesa’s power generation plants —Hwange, Kariba, Harare, Munyati and Bulawayo – are constantly breaking down because the equipment has outlived its lifespan.

However, load-shedding is higher in winter owing to increased electricity demand as consumers turn to gadgets such as heaters and geysers.

With biogas,nothing goes to waste

With biogas,nothing goes to waste

INSIDE the Zimbabwe Domestic Biogas Programme (ZDBP) information trailer, the flame on the biogas stove suddenly flares and flickers as if blown by the wind. The mobile information trailer, designed to resemble a kitchen, is connected to a biogas digester built underground, which converts cow dung into biogas that can be used for cooking, heating and lighting.

 

BY MASIMBA BIRIWASHA

Upon seeing the dancing flames, Sibongile Mandarira (35), a teacher based in Masvingo, lights up.

“Until today, I had only read about biogas technology, but this experience is a real eye opener. I saw how it actually works. I’ve already made my mind up to install a digester at my rural home because it is smart,” she said, the brightness of her eyes betraying her curiosity.

“I will use biogas for breeding chickens and lighting chicken runs. I will also use it for cooking and refrigeration.”

Mandarira said that prior to visiting the information trailer, which was stationed at the Rural Electrification Agency (REA) exhibition stand at the recently-ended Zimbabwe International Trade Fair (ZITF) she did not know much about biogas technology. Despite that biogas has great potential to increase access to clean, reliable and affordable energy in Zimbabwe, particularly in rural areas, the technology remains novel to many people.

Against this background, the domestic biogas programme, a five-year initiative involving the Ministry of Energy and Power Development, Ministry of Agriculture, Mechanisation and Irrigation Development, Rural Electrification Agency, Netherlands Development Organisation (SNV) and Humanist Institute for Co-operation (Hivos) is employing the information trailer to demonstrate the efficiency of biogas in order to encourage uptake of the technology.

“Biogas is a very technical concept. Many people are not familiar with it despite its immense potential to provide energy for cooking, heating and lighting at domestic level. Merely talking about biogas without demonstrating how it works is not effective in encouraging people to take up the technology,” SNV’s renewable energy advisor Chandi Mutubuki-Makuyana, said.
The domestic biogas programme is aimed at increasing access to sustainable, clean and reliable energy sources for domestic households and establishing a vibrant biogas sector that will benefit more than
67 000 households.
The project follows a market-driven approach in promoting the dissemination of biogas technology.
Biogas is a gas mixture that is predominantly made up of methane and carbon dioxide. It is created as a by-product when organic material decomposes in airless conditions. When the decomposition process occurs in an enclosed environment, it can be captured and used as a natural fuel source. The slurry left over from this process is an excellent organic fertiliser.

The use of biogas can be especially beneficial in rural areas, where there is no access to any other energy source and deforestation and indoor pollution are an issue. For people in rural areas, biogas is a much cleaner and environmentally-friendly alternative fuel source.

It burns with minimal carbon dioxide output and uses products that are readily available.

Potential environmental benefits include reduction of local pollutants, reduced deforestation due to logging for fuel and increased sequestration of carbon in soils.

With a minimum of five cows, it is possible to generate enough cow dung to feed a small sized digester. It costs approximately between $800 and $2 000 to construct a biogas digester.

“People are not so much interested in the digester itself in as much as what the gas can do. What the gas does is what excites people. We want to show people that with biogas nothing goes to waste. You get the gas from waste and you get slurry which is equivalent to Compound D fertiliser,” Mutubuki-Makuyana said.

A basic biogas digester consists of a tank in which the organic material is digested, combined with a system to collect and store the biogas produced.

The slurry of dung and water ferments in the tank and the pressure of the biogas produced pushes the slurry out of one end.
The gas is piped from the top of the tank to a biogas cooking stove and biogas lights.

“Biogas changes people’s lives. Our outreach with the information trailer has been good because we are not talking about biogas theoretically. Most people cannot visualise it if you just tell them, but with the trailer we are conducting demonstrations. We hope to take the trailer from district to district and show people the advantages of biogas,” Mutubuki-Makuyana, adding that they would target households with cattle said.

According to Hivos Southern Africa Hub’s energy programme manager Soneni Ncube, the purpose of the information trailer is to inform the public about biogas as a cheap and modern form of energy.

“Biogas is clean, it produces no smoke, it is healthy and reduces the drudgery of labour faced by women and girls in looking for firewood. One can produce it from their own livestock and the slurry that comes out after manure is digested to produce biogas is a good fertiliser and is even better than raw manure,” Ncube said.

“Once people learn and see what they can do with biogas, it is hoped that this will increase the adoption rate of this form of energy as an alternative energy source for rural and peri-urban households instead of wood, thus reducing deforestation and reduction of carbon emissions into the atmosphere. This way it reduces the effects of climate change.”

Hwange resumes power generation

Hwange resumes power generation

Business Reporter
HWANGE Thermal Power Station is back on line after a weeklong shutdown due to a technical glitch that saw the country’s total power output drop to 801MW from about 1,200MW.

According to the Zimbabwe Power Company (ZPC)’s power generation report yesterday, Hwange was generating 294MW from zero in the last few days.

The station is the largest power plant in the country with a generation capacity of 920 megawatts followed by Kariba Hydro Power Station at 750 megawatts.

The ZPC report indicated that total power output had increased to 1,081MW with Kariba generating 717MW.

Small thermal stations — Bulawayo, Harare and Munyati — were producing 24MW, 30MW and 16MW respectively.

The temporary shutdown at Hwange had worsened power outages and crippled operations in productive sectors of the economy.

Zimbabwe has an average national demand of 2,200 megawatts that it cannot meet due to obsolete equipment at its five existing power stations.

ZPC says repair works are being undertaken on the steam pipe hangers, turbine thrust pads as well as other opportunistic maintenance jobs.

The government has embarked on massive power generation projects that will see the country generate more than 3,500 megawatts in the next five to six years.

Hwange shutdown to worsen power outages

Hwange shutdown to worsen power outages

POWER generation at the Hwange Thermal Station has ground to halt due to a technical glitch resulting in the country’s electricity generation going down to 801 megawatts from about 1,200 megawatts.

Hwange Thermal is the largest power plant in the country with a generation capacity of 920 megawatts followed by Kariba Hydro Power Station at 750 megawatts.

The temporary shutdown at Hwange is set to worsen power outages and cripple operations in productive sectors of the economy.

Zimbabwe has an average national demand of 2,200 megawatts that it cannot meet due to obsolete equipment at its five existing power stations.

As at April 27, Bulawayo and Munyati Thermal Power Stations were producing 24 megawatts each while Harare Thermal Power Station and Kariba Hydro Power Station produced 30 megawatts and 723 megawatts respectively.

According to the Zimbabwe Power Company (ZPC), the giant power plant has been shut down following the loss of a T1A transformer after backup protection.

“This led to loss of auxiliary supplies on units 2 and 3 that were in service and subsequently took them out. Unit 1 was taken out of service on April 23 at 19.59HRS following a fire incident on BC2 burner. Inspections are in progress to identify damaged cables,” said ZPC in its daily power update.

“Unit 4 was taken out of service on April 25 at 17.08HRS due to LP front shaft vibrations and boiler tube leaks. Works are still in progress.”

The power utility said unit 5 had been down due to poor vacuum since February 5, 2015 at 12.31HRS and “on attempting to return to service, it developed governor challenges”.

Repair works were being undertaken on the steam pipe hangers, turbine thrust pads as well as other opportunistic maintenance jobs, it said adding, unit 6 was taken out of service on April 24 due to a boiler tube leak.

“Works have been completed and preparations to bring the unit back . . . are in progress,” said ZPC.

The thermal power stations — Harare, Bulawayo and Munyati are currently producing 30MW 24MW and 24MW respectively. This is against installed capacity of 75MW, 90MW and 100MW.

ZPC director Noah Gwariro has said power generation at Harare Power Station will double from 30MW to 60MW by the end of this month on expected completion of repairs to one of its turbo alternators.

Last year, the government contracted Sino-Hydro to build two units at the country’s largest power plant at a cost of $1.5 billion.

The project will add 600MW onto the national grid.

The expansion project at Hwange is expected to be completed in 42 months from commencement date, according to the contractor.

Under the deal, ZPC will get $1.17 billion or 80 percent of the funds for the plant through concessionary funding from China Exim Bank while the same institution will provide the balance at commercial rates.

he government has embarked on massive power generation projects that will see the country generate more than 3,500MW in the next five to six years.

The 300MW Kariba South expansion is already underway at a cost of more than $500 million to be completed in 2018.

Some of the projects in the pipeline include the 600MW power plant to be constructed by China Africa Sunlight Energy in the Gwayi area of Lupane, the 800MW Batoka Gorge hydro power project as well as renewable projects in solar and gas.
