Ghana’s 399 MW Bui plant completed
A ceremony that included Ghanaian president John Dramani Mahama marked the official commissioning of the country’s 399 MW Bui project in mid-December.
The US$800 million project was constructed by China’s Sinohydro Corporation on the Black Volta River, with funding provided by the governments of Ghana and China. The project is intended to help alleviate some of Ghana’s energy deficiencies, with Mahama earlier saying he hoped the country can increase its overall energy capacity to 6,000 MW by 2015.
Project developer the Bui Power Authority (BPA) received the first of three 133 MW turbine-generator units in January 2012, and it began generating power at the site in May 2013.

Scotland plans to develop Choire Ghlais project
Plans for the 600 MW Choire Ghlais pumped-storage project have been given the go-ahead by Scottish Minister of Energy Fergus Ewing, opening the door for a plant that could eventually supply as much as 10% of the country’s peak electricity demand.
Developer Scottish and Southern Energy (SSE) Renewables gained unanimous support for Choire Ghlais (also called “Coire Glas”) from the Scottish Highland Council in November 2012 after filing an application in February of that year.
Ewing’s approval gives SSE planning permission. Work on the project is expected to take up to six years and will create a projected 150 jobs.
Eighth unit operating at RusHydro’s Boguchanskaya

Work moving forward on projects in Peru
The Bank of New York Mellon has appointed Mott MacDonald as independent engineer to monitor construction of the 406 MW Chaglla project. The US$1.2 billion plant is being developed on the Huallaga River by Empresa de Generacion Huallaga S.A., a subsidiary of Brazil’s Odebrecht Group.
The Chaglla complex, to be completed by 2016, includes a 400 MW main power and a 6 MW auxiliary plant, in addition to a 202 meter-long concrete-faced rockfill dam that will form a 466 hectare reservoir. A surface powerhouse and diversion, spillway and headrace tunnels are also included.
“This nationally significant project will impact Peru’s economic development considerably by creating thousands of jobs and increasing its electric generation capacity to meet the needs of the country’s rapidly growing economy,” Mott MacDonald project director Clare Rhodes-James said. “Once completed, this project will be Peru’s third-largest hydropower facility, providing approximately 13% of the country’s installed hydropower.”
In other news, Peru’s Ministry of Energy and Mines has granted temporary concessions for a pair of hydropower project proposals in the country’s Cusco department.
Included in the recent resolution are an unnamed 49.7 MW plant being developed by Empresa de Generacion Electrica Ccollpani and the 62.1 MW Vilcanota 4 being developed by Empresa de Generacion Electrica Santa Maria. The companies filed their concession requests in March and July of 2013, respectively, and now have 24 months to carry out feasibility studies.
China’s Xiangjiaba awarded Project of the Year
China’s 6,400 MW Xiangjiaba plant was recognized by the editors of Power Engineering and RenewableEnergyWorld.com as the 2013 Hydro Project of the Year during the recent Power Generation Week conference and exhibition held in Orlando.
Work on the US$6.3 billion project, on the Jinshajiang River between Tibin and Shifu counties in the Yunnan Province, began in November 2006. Xiangjiaba was developed by China Three Gorges Corporation and outfitted by Alstom, which was awarded the contract in 2008. The first unit went into commercial operation in November 2012, with the last being commissioned in July.
Xiangjiaba is the third largest hydroelectric facility in China, trailing only 22,500 MW Three Gorges and 13,860 MW Xiluodu. (For more information on Xiangjiaba, look for an article in the March-April issue of HRW-Hydro Review Worldwide.)
