Report: Large hydro still dominant among renewables
Large hydropower projects remain the world’s dominant source of renewable electricity, according to the Renewable Energy Network for the 21st Century (REN21).
REN21’s Renewables 2007 Global Status Report, released to coincide with the Washington International Renewable Energy Conference (WIREC), found large hydropower provided 15 percent of the world’s power generation in 2007.
Other renewables, such as small hydropower, wind, biomass, and solar power, provided 3.4 percent of generation, while fossil fuels provided 67 percent and nuclear added 14 percent.
REN21, which was created at a 2004 international renewables conference in Bonn, Germany, defines small hydropower as projects of less than 10 mw, 30 mw, or 50 mw, depending on which country is providing the statistics.
The report said “new” renewables capacity, including small hydro, totaled 240,000 mw in 2007, while large hydro capacity totaled 770,000 mw. Investment in new renewables in 2007 totaled US$71 billion, while investment in large hydropower totaled US$15 billion to US$20 billion.
The report said new renewables grew at rates of 15 to 30 percent annually from 2002 to 2006, while other technologies, including large hydropower, grew at rates from 3 to 5 percent.
“For the power generation sector, large hydropower remains one of the lowest-cost energy technologies, although environmental constraints, resettlement impacts, and the availability of sites have limited further growth in many countries,” the report said. “Large hydro supplied 15 percent of global electricity production in 2006, down from 19 percent a decade ago.”
Large hydro grew during 2002-2006 at a global average of 3 percent per year, but less than 1 percent in developed countries. China saw the highest growth, at more than 8 percent per year during the period. China added about 6,000 mw of large hydro, plus 6,000 mw of small hydro in 2006.
The top five hydro producers in 2006 were China with 14 percent of world production, Canada and Brazil with 12 percent each, the United States with 10 percent, and Russia with 6 percent.

South Africa nears contracts for 1,332-mw Ingula
South African utility Eskom Holdings Ltd. said it is finalizing major construction and equipment contracts for the 1,332-mw Ingula pumped-storage project in South Africa.
Eskom is developing Ingula, formerly called Braamhoek, in the Little Drakensberg Mountains near Ladysmith, on the border between Free State and KwaZulu-Natal. Completion is scheduled for mid-2013.
The project is to feature two dams, one atop the Drakensberg escarpment and the other at the bottom, with water tunnels, an underground powerhouse complex with four turbine-generators, access tunnels, and access roads.
Eskom said in February it is finalizing contracts for upper and lower dam construction, main underground works, and the hydro-mechanical plant.
Contracts already awarded include: access roads, Grinaker/ LTA; main access tunnel, CMC Mavundla; infrastructure, Afriscan; aggregate quarry, B&E Quanza Group; supervision, BCJV, and design monitoring, BCJV.
Excavation on a 6-by-6-meter construction access tunnel had advanced to 1.3 kilometers, the utility said. A 9-by-9-meter main access tunnel also has been started. Access roads to the site offices and upper dam are close to completion.
Eskom said a team of horticulturalists from the Bloemfontein Botanical Gardens has been working on the upper dam site, removing plants prior to dam wall construction. The team is assessing all species in the area and removing a number of plants for replanting at gardens in Bloemfontein.
Last year, Murray & Roberts, a South Africa construction and engineering group, completed construction of a 1,050-meter exploration tunnel. The tunnel will carry all high-tension cables from the powerhouse complex and is fitted with instrumentation to verify geotechnical information.

Bosnia names Statkraft to build Vrbas projects
Bosnia’s Serb Republic government named Norwegian utility Statkraft its partner in the construction of hydropower plants on the Vrbas River that could cost up to 100 million euros (US$147.8 million).
Statkraft, which had already been cleared by the energy ministry and the concessions commission, wants to build several small hydro plants on the Vrbas in northwestern Bosnia, Prime Minister Milorad Dodik said.
Dodik said Statkraft would conduct analysis and a feasibility study to determine the number of plants, their capacity, and the total value of the project.
Bosnia’s Federal News Agency said the proposed project area, where the Vrbas joins the Sava River, is the site of four possible projects.

European bank funds Austria’s 480-mw Limberg 2
The European Investment Bank (EIB) approved an additional 40 million euros (US$62.1 million) in funding for the 480-mw Limberg 2 pumped-storage project being built by Verbund Austrian Hydro Power near Kaprun, Austria.
Verbund is building an underground powerhouse containing two pump-turbines as part of the Glockner Kaprun scheme, near the 240-mw Kaprun project. Limberg 2 is to employ the existing storage reservoirs of Mooserboden and Wasserfallboden. In February, Verbund received for bids for electrical distribution and control equipment for the project.
EIB reported a finance contract for the 40 million euros was signed in March. The bank approved financing of 200 million euros (US$310.8 million) for the project a year earlier. The latest approval brings total bank funding to 240 million euros (US$372.9 million).
In late 2007, Verbund awarded a contract to Hans Kunz GmbH of Austria to supply safety shut-off valves and slidegate valve chamber equipment and another contract to WPK Werkstoff-Planung-Kontroll Ges.m.b.H of Austria for oversight of equipment installation.
In April 2007, Voith Siemens Hydro Power Generation reported the successful model testing for two 240-mw pump-turbines it is to supply. In 2006, Verbund awarded contracts to Andritz VA Tech Hydro to supply two motor-generators, excitation systems, and steel tunnel linings of the pressure shaft and the high-head manifold.
Commissioning of Limberg 2’s first 240-mw unit is scheduled for autumn 2011, with full commercial operation in March 2012.
n CONTRACT AWARD:
India firm to build Nepal’s 300-mw Upper Karnali
Nepal awarded a contract to a consortium led by India’s GMR Group to build the 300-mw Upper Karnali project on the Karnali River.
GMR announced its units and partner Italian-Thai Development Project Co. signed a memorandum with the government of Nepal. The build-own-operate-transfer award was made as the result of Nepal’s first international competitive bidding process for a large hydro project.
The consortium agreed to provide 12 percent of the project’s power free to the government and to give Nepal Electricity Authority a free 27 percent equity in the company formed to develop Upper Karnali. Most power generated by the project is to be exported to India’s grid.
Nepal announced bidding in December 2006 for Upper Karnali and the 402-mw Arun 3 and 600-mw Budhi Gandaki hydroelectric projects. GMR said an evaluation committee awarded it top ranking for both Upper Karnali and Arun 3. However, GMR said, the government decided to allocate only one project per developer, resulting in the Upper Karnali award to the GMR-led group.
Romanian utility Hidroelectrica SA awarded a 9.58 million lei (US$3.94 million) contract to S.C. UCM Resita SA of Romania for rehabilitation of a generating unit of the 38-mw Arcesti hydro project on the Olt River. S.C. UCM Resita was the sole bidder for the contract.
Philippines power producer First Gen Hydro Power Corp. said it commissioned VA Tech Hydro GmbH of Austria to perform major refurbishment and upgrade work at the 100-mw Pantabangan hydroelectric project to increase capacity initially by 18 mw. VA Tech Hydro is to refurbish two turbine-generators. First Gen Corp. acquired the project in a 2006 privatization auction.
Finland utility Kemijoki Oy awarded a contract to Alstom Hydro Sweden AB to uprate two generators of the 110-mw Pirttikoski hydroelectric project on Finland’s Kemijoki River.
