    MIGA backs development of 420 MW Nachtigal hydropower in Cameroon

    MIGA, a member of the World Bank Group, has issued EUR 164.5 million (USD 188 million) in guarantees to two investors in the Nachtigal Hydropower Company. The agency has provided breach of contract cover for up to 15 years to French power developer and operator EDF International, as well as STOA, a French infrastructure investment vehicle that focuses primarily on Africa.

    MIGA guarantees have been provided alongside payment and loan guarantees from the IBRD, and an investment, loan and risk management swaps by IFC.

    The 420 MW Nachtigal Hydropower Project on the Sanaga River, about 65 km northeast of Yaounde, will contribute an additional 30% of installed generation capacity in Cameroon, along with significant climate co-benefits.

    The project is being developed on a build, own, operate and transfer basis under a 35-year concession agreement between the project company and the Republic of Cameroon, and a power purchase agreement exists between the company and Energy of Cameroon a privately-owned electricity distribution company. One of few hydropower public-private partnerships in Sub-Saharan Africa, the project will sell power to ENEO at a rate of EUR 0.061/kWh (USD 0.070) among the lowest tariffs for a hydropower plant.

    Nachtigal will be connected to the Southern interconnected grid, which represents about 94% of Cameroon’s national electricity consumption.

    MIGA Executive Vice President and Chief Operating Officer Keiko Honda said that “As a project in an IDA-eligible country, as well as one with significant climate change mitigation benefits, the Nachtigal Hydropower Project is a high priority for MIGA. Equally importantly, I am pleased this project has mechanisms to help address environmental and social concerns, which are of utmost importance to MIGA.”

    As of 2015, total power generation in Cameroon reached 6,426 GWh, with a total installed capacity of 1,286 MW of which hydropower accounts for about 60% of total installed capacity.

    Six out of 10 of Cameroonians have access to electricity, and peak demand is expected to quadruple by 2035. The country has the third largest hydropower development potential in Sub-Saharan Africa, and forecasts estimate that hydropower will represent about 75% of the energy mix by 2023.

    A comprehensive environmental and social management plan has been prepared and addresses environmental impacts, health and safety, labor influx, and organizational capacity. An integrity due diligence review was undertaken by IFC.

    The project was originally developed through the IFC Infraventures program.

    Commenting on the transaction, Ms Marie-Laure Mazaud, deputy chief executive officer of STOA, added that "The Nachtigal Dam provides a concrete response to the significant demand for electricity in Cameroon, and is a reference project for the development of similar hydro projects in Africa in the near term. We are pleased to collaborate with the Republic of Cameroon, EDF, IFC and Africa50 to provide sustainable and accessible energy for the Cameroonian population. The social economic impact of Nachtigal project will be huge in terms of local employment and economic growth."

    RusHydro to add solar to Nizhne-Bureyskaya hydropower plant'

    Water Power Magazine reported that Russian energy firm RusHydro is to develop a pilot solar project on the Nizhne-Bureyskaya hydroelectric plant, helping to unlock additional output at the 320MW plant. The 1.275MW solar plant will feature PV modules manufactured by Hevel with overall area of 6700m2. It will have an expected annual production of 1.4GWh and is expected to reduce cost of electricity for the hydro plant’s own needs thus unlocking additional output.

    The Amur region where the hydro plant is located is ideal for the development of PV generation with 240 sunny days in a year, says RusHydro. The ground-filled dam of Nizhne-Bureyskaya has 30,000m2 of open unshadowed space and the tailrace slope of the dam is facing South-West, making it an optimal location for capturing solar energy.

    The plant will use heterojunction solar modules manufactured in Russia with unit capacity of 370W. The new generation PV panels have an efficiency rating of over 23%, or 20% more efficient than traditional polysilicon panels and are equally operational under both, low and high outdoor temperatures.

    Nizhne-Bureyskaya is the second plant of the Bureysky hydropower complex and acts as counter-regulator for Bureyskaya hydropower plant.

    The solar plant is expected to be commissioned at the end of 2019.

    Polavaram to add 980 megawatts of hydel power to state grid

    Times Of India reported that Polavaram project, considered the lifeline of Andhra Pradesh, will also make the state surplus in power generation. It will add about 980 megawatts of hydel power to the state grid. At present, the state has an installed capacity of 2,336 megawatts of hydel energy. Once Polavaram and other projects are completed, the total hydel power generation in AP will touch 4,600 megawatts.

    Chief minister N Chandrababu Naidu, who reviewed developments in the energy sector with senior officials on Sunday, said the Polavaram dam, when completed, will help stabilisation of power grid in the state. By the time the dam is ready, there will also be integration of solar (2,840 megawatts) and wind (4,061 megawatts) power. Officials told the chief minister that engineering works of Polavaram hydel project are progressing as per schedule, with excavation work of power house scheduled to be completed by June.

    The APGenco has planned to complete the project within five years at an estimated cost of INR 5,339 crore. Officials told the chief minister that the project will be ready before the 2022 deadline.

    Mr Naidu directed officials to complete the Polavaram hydel plant (12 hydel units each with a capacity of 80 megawatts) at least six months ahead of the schedule, on a mission mode. He also emphasised the need on generating clean and green power. Mr Naidu said that “The state government is making efforts to supply the highest quality power to consumers without increasing power tariffs. The demand for electricity would increase due to the rapid economic growth in the state.”

    Stating that there is a strong correlation between GDP growth and increase in power generation capacity, Mr Naidu said several global entities had showed interest to set up their business establishments in AP only because of the measures the state government has taken to provide water and energy security.

    He said the second phase of reforms introduced by the state government led AP to bag many awards in power sector. The CM added that “The government has provided relief to 18 lakh farmers by supplying nine hours of free power per day. Polavaram will herald a unified development of irrigation, water supply to industries and providing drinking water apart from bulk hydro power generation.”

    Tanzania launches Africa’s 4th largest hydropower project

    CGTN Africa reported that government of Tanzania has unveiled a USD 3 billion hydropower project, that upon completion, will be Africa’s fourth largest hydropower station. The contract has been awarded to a consortium of two Egyptian companies led by Arab Contractors.

    Speaking during an official ceremony to officially hand over the site to contractors, the Tanzanian Minister of Energy, Merdad Kaleman, said Tanzania is committed to delivering the project through its own government funding. He said that “We want to deliver this project as a way to honour our Father of the Nation Mwalimu Nyerere who wanted to deliver the Rufiji Hydro Dam project but could not make it in 1980s, due to costs.”

    According to Kaleman, the government of President Magufuli is committed to transforming the country from one ridden by power woes to an industrialized one, despite concerns voiced by some environmentalists.

    The project output is almost double all current power sources combined.

    He added the economic advantage of the project to the industrialising economy of Tanzania Taenergy outweighs the challenges. The minister said that “Apart from 2,115 MW electricity output, the project will unleash fishing tourism potentials and flood control mechanisms in the reservoir area.”

    The project is expected to be completed in 3 years.

    17 Tanzanian firms win tenders for logging in hydropower project area in game reserve

    Xinhua reported that Tanzania's forest watchdog said 17 local companies have won tenders for logging in an area earmarked for the Stiegler's Gorge hydropower project in the Selous Game Reserve. Mr Dos Santos Silayo, Chief Executive of the Tanzania Forest Services Agency, said the firms started logging in the area in December last year. Mr Silayo in an interview with Xinhua said that "We expect that the logging process will take one and a half years beginning December last year.”

    He said since the forest agency announced the logging tenders in May last year, no international company applied until the tenders were closed.

    TFS said last year its intention was to clear the project area before implementation of the project started.

    Mr Silayo said that "We opened the tenders for cutting down the trees so that they can be used for various purposes rather than destroying them.”

    However, Mr Silayo said the successful tenderers will not be allowed to export the logs, according to the Forest Regulations of 2004 unless otherwise permitted by the minister responsible for natural resources and tourism.

    Major boost for 4 hydro projects worth INR 45,000 crore

    Economic Times reported that government expects a big push to hydropower sector having received clearances for four projects worth about INR 45,000 crore. Last week, the project investment board (PIB) of finance ministry recommended NHPC’s INR 28,000 crore Dibang project and a proposal to acquire and complete Lanco Infratech’s Teesta VI project worth nearly INR 5,400 crore.

    NHPC bagged the 500-mw Teesta hydro power plant under insolvency proceedings for INR 907 crore. The project will require further investments of about INR 4,500 crore for completion and will now be put before the Union cabinet for approval. NHPC has installed generation capacity of 7071 mw and another 3800 mw under construction.

    “The hydropower sector was almost written off due to the delays and languishing of the projects. The recent developments will revive investments in the sector.

    While bigger PSUs are shying away from bidding in insolvency court, NHPC, a miniratna company with limited financial autonomy, has set precedence,” said a government official.

    The National Green Tribunal had in its judgment on November 13 dismissed an appeal filed by appellant Pradip Kumar Bhuyan against the government for granting environment clearance to the project.

    Danfoss Editron to double lifespan of Siikakoski hydro plant

    Danfoss Editron is demonstrating how electrification technology can extend the life of hydropower plants by providing two electric generators to Finnish energy group KSS Energia. The generators will play a key role in doubling the operational lifespan of the Siikakoski hydro plant in Kouvola, Finland. The Siikakoski plant, which has been in operation since the early 1960s, was taken over by KSS Energia in 1976 when it was connected to the company’s energy network that provides power to customers in the Kouvola region. Its existing machinery dates back to the 1960s and needs to be fully replaced in order to keep the plant running and capable of providing power to the local area.

    Danfoss Editron is delivering a full generating system, including two 1300kW, 125rpm electric generators and two 600kVAr reactive power compensation units, as part of the plant’s upgrade. The new generators, which feature direct drive permanent magnet technology, are more compact and 20-30% lighter than traditional synchronous machinery. As well as offering very high efficiency, the generator’s permanent magnet technology also means that extremely low maintenance is required once the plant is operational. Danfoss Drives is providing the project’s state-of-art reactive power compensation system, which is based on the company’s active front end technology.

    The first 1.3MW generator was successfully installed at Siikakoski at the end of 2018, with another 1.3MW unit expected to be commissioned by the end of 2019. Once fully operational, the 2.6MW plant will power approximately 500 homes in the local region annually for the next 50-60 years.

    The Siikakoski project forms part of Danfoss Editron’s new renewables market offering. This service began with Danfoss’ acquisition of AXCO-Motors late last year, which boosted AXCO-Motors’ existing hydro offering with the diverse product portfolio of Danfoss Editron and Danfoss Drives. By coming together, Danfoss Editron can help provide renewable energy to rural areas via its sophisticated EDITRON system.

    Vattenfall to add 600 MW more output from hydro power by 2023

    Hydro power has enormous reservoirs, and is a huge 'green battery' that balances the energy system throughout the entire Nordic Region. More solar and wind in the energy system create a need for even greater flexibility, so that generation can be quickly sped up or slowed down. Consequently, hydro power plants need to be adapted to these new circumstances. Vattenfall invests SEK 1 billion per year in hydro power maintenance. A major project has been under way since 2015 to upgrade the power plants and raise their output and flexibility. By 2023, hydro power will have been expanded by 600 MW without a single new dam being built. This is equivalent to the output of half a nuclear power plant, or roughly 100 modern wind turbines, and is a significant contribution to Sweden's climate goals and Vattenfall's goal of enabling fossil-free living within one generation.

    However, the primary purpose is to improve the ability to respond faster to changes in the need for generation, rather than to generate more electrical power.

    Around 20 power plants have already been upgraded in various ways, increasing the available output by around 450 MW.

    Mr Tord Eriksson, Head of Production, Vattenfall Vattenkraft said that "In most cases the efficiency and output of the plants is improved after the renovation, as new turbines, generators and transformers are more efficient than the ones being replaced. In other cases, other measures are being taken, such as reviewing the Land & Environment Court rulings and obtaining new ones.”
