Small Hydro

Significant small hydro activity in Uganda

In Uganda, one small hydro project has begun operating and two are on the verge of being developed.

The 6.5 MW Ishasha plant began operating in November 2011 in the Kigezi Sub-Region. Operation of this US$15 million facility should help reduce the country’s power outages, government officials say.

The facility, on the Ishasha River in Kyeijura Kanyantorogo Sub-county, will not only provide power to the Kanungu district, but also nearby Rukungiri, Ntungamo, Kabale and Kisoro districts.

Ishasha was built by ECO Power IT under a memorandum of understanding that says the Sri Lanka-based company will operate the station and sell its power to the government for 30 years.

The project was funded by three Sri Lankan financial institutions — the National Development Bank of Sri Lanka, Hatton National Bank and Commercial Bank of Sri Lanka.

In development news, the Netherlands Development Finance Company (FMO) has arranged a US$24 million senior loan for financing of the 14 MW Kilembe run-of-river plant in Uganda.

Of the $24 million, FMO will provide $12 million, the Emerging Africa Infrastructure Fund will provide $6 million, DEG $4 million and Finnfund $2 million. DEG is the investment arm of Germany’s government, and Finnfund is a development finance company that provides long-term risk capital for projects in developing countries.

The 6.5 MW Ishasha powerhouse on the Ishasha River in Uganda began operating in November 2011, providing expected annual power generation of 28 GWh.

The project is being developed by South Asia Energy Management Systems LLC (SAEMS) and will be located in the village of Kilembe, in the Kasese district of Uganda.

The Kilembe project — along with SAEMS’ earlier 19 MW Mpanga project — are part of an overall plan to develop 13 small hydro projects in Uganda.

And international consulting firm Royal Haskoning will soon begin work on a project that will provide electricity to 350,000 people in Uganda’s rural western region.

A press release says Royal Haskoning has already arranged a public-private partnership that includes a US$15.5 million Dutch ORIO subsidy, $16.8 million from the Uganda Ministry of Energy and Mineral Development, and $9 million from private investors in a plan being called the “Western Uganda Mini-Hydropower & Rural Electrification Project”.

Under the plan, a cluster of 10 small hydropower units with capacities of 7 to 10 MW will be installed alongside a transmission and distribution system. Royal Haskoning says this will increase the percentage of Uganda’s rural population connected to the grid from less than 6% to 7.5%.

Vallibel Power begins project operations in Sri Lanka

Vallibel Power Erathna, a Sri Lankan firm, began commercial operations at the 4.65 MW Kiriwaneliya project in December 2011.

The project, which uses the potential of the Maskeli Oya and the flow of several other feeder streams, is in the Ginigathhena Divisional Secretariat Division of the Nuwaraeliya District. The powerhouse is expected to generate about 16 GWh annually, which will be fed to the national grid.

Swiss utility BKW acquires Italian hydro facilities

BKW FMB Energy Ltd. is acquiring five run-of-river hydropower plants from Italian energy utility Sorgenia.

Financial details of the agreement have not been disclosed.

The five facilities have a collective installed capacity of nearly 8 MW and are in the Aosta Valley in northern Italy. Annual production from these five plants is about 30 GWh

Switzerland-based BKW already owns and operates eight hydropower plants in Italy in the Lago di Iseo region with a total capacity of 42 MW. The company acquired these plants in 2006.

Developer wins loans to build 8.6 MW San Lorenzo in Panama

A unit of Spanish developer Grupo Cuerva Espana has received US$21 million in loans to construct the 8.6 MW San Lorenzo project on Panama’s Fonseca River.

Cuerva subsidiary Hidroelectrica San Lorenzo S.A. signed a loan agreement in December 2011 for the financing, of which US$10.5 million is coming from the Inter-American Investment Corp., a unit of the Inter-American Development Bank. Cuerva Chairman Ignacio Cuerva Valdivia says other financing is coming from Banco Internacional de Costa Rica S.A. and Compania Espanola de Financiacion del Desarrollo.

San Lorenzo is a run-of-river project in Chiriqui Province that includes a concrete dike with five gates located along the Fonseca, a short canal from the river, and a powerhouse containing two 4.35 MW Kaplan turbine-generators. It is expected to produce 40 GWh annually, delivered to Panama’s grid by a 12 km-long transmission line.

Spanish firm Balino S.A. de Espana is to supply and install equipment, while Saret de Costa Rica is handling construction of the project.

New bill could increase small hydropower in Poland

Poland is looking to increase the share of renewable electricity within its energy mix from 10% to 15.5% over the next decade, and this would include investment in small hydro plants.

A new draft bill would help Poland, which generates more than 90% of its electricity with coal, meet the EU’s renewable production standards by 2020. A 2010 EU directive says members will reach a 20% share of energy from renewable soruces by the end of the decade.

“Our goal is to simplify, optimize and improve the support mechanism for renewables,” says Deputy Economic Minister Mievczslaw Kasprzak. According to Kasprzak, the country’s annual spending on renewables could increase from less than US$1 billion in 2012 to $2.46 billion in 2020.

Poland’s hydroelectric output accounts for less than 2% of the country’s overall output, according to a study performed by Coalition Clean Baltic. CCB’s report also says almost 90% of Poland’s hydro potential remains untapped, meaning there is significant room for growth.

The proposed bill would divert investment to solar, biogas, offshore wind and small hydro. It would cut support for biomass, old hydro facilities and on-shore wind farms.

European bank funds 5.1 MW Cerruje 1, 2 in Albania

The European Bank for Reconstruction and Development (EBRD) has approved a €3 million (US$3.9 million) loan to finance construction of the 5.1 MW Cerruje 1 and 2 projects on Albania’s Benji River.

EBRD made the loan in December 2011 to an Albanian private developer, Energy Partners, under the bank’s Western Balkans Sustainable Energy Direct Financing Facility.

Energy Partners is to build the two hydro plants 140 km northeast of Tirana. They are to generate up to 14.7 GWh annually, helping to offset production of 9,500 tons of carbon dioxide by other power plants.

Energy Partners plans to develop a total of five hydro plants on the Benji, for which the company received a 35-year concession.

Guyana, EU teaming up for Chiung River Falls project

The European Union (EU) will provide funding for a new 330 kW hydroelectric plant along Guyana’s Chiung River, with the stipulation that the country construct a new secondary school first.

The anticipated cost of the new Kato facility is US$3.11 million. Of that, the EU has said it will contribute about $2.39 million under the 10th European Development Fund (EDF), while the Guyana government will contribute the remainder.

The EU says construction of the school is essential before finalizing its investment because the school is anticipated to be the new plant’s primary beneficiary. “The secondary school is foreseen to be the main electricity consumer, and therefore as such forms the basis for feasibility of the investment,” an EU release says.

Officials hope that construction on the Kato plant can begin by February 2013, with completion scheduled for February 2015.

Ecuadorian utility names supplier for small hydro project

Ecuadorian utility Empresa Electrica Quito (EEQ) has awarded a US$6.53 million contract to Ensilectric to manufacture and install electromechanical equipment for the 10 MW Victoria hydro plant in Napo Province.

Ensilectric will have 21 months to install the equipment for the Victoria hydro facility.

Scottish utility exploring benefits of small hydro network

Scottish Water has revealed that they will soon embark on a US$31 million plan that will see the utility’s existing water treatment plants partially converted to produce hydroelectric power.

According to a company release, Scottish Water will use the flow in its large water supply pipes to generate power for its treatment plants, resulting in a treatment cost reduction of 10%.

The conversion plan is made possible by legislation introduced in 2010 by First Minister and Scottish National Party leader Alex Salmond.

More than 30 potential sites have been identified in areas including Lanarkshire, the Borders, Stirlingshire, Angus and Fife. Many of the proposed schemes make use of Scottish Water’s existing buildings, although the company might need to construct additional buildings and electrical infrastructure in some areas, the release says.

In addition to this project, Scottish Water’s commercial arm, Scottish Water Horizons, has recently installed a microturbine at the Touch water treatment works in Stirling.
