India’s NTPC eyeing 9,750 MW hydropower project
India’s NTPC power company has submitted a pre-feasibility report for a 9,750 MW project on the Brahmaputra River in Arunachal Pradesh.
The Siang Upper facility would be the second largest in Asia after China’s Three Gorges and would increase the state-owned utility’s overall production by more than a quarter.
Sources say NTPC’s filing was partially prompted by reports of Chinese plans to construct a hydro project upstream on the Brahmaputra (called Yarlung Tsangpo in China). The countries have a doctrine of prior appropriation, which says the river’s rights of first appropriation belong to whoever utilizes it first.
Work on Upper Kotmale in Sri Lanka nearing completion
Construction of Sri Lanka’s controversial Upper Kotmale plant is nearing completion, according to Sri Lankan news sources.
The 150 MW project was first proposed in 1968 but was stymied for decades due to concerns about its environmental impact. A favorable court ruling and a US$270 million loan from the Japan Bank for International Cooperation (JBIC) in 2006 allowed construction to begin.
The project was “92% complete” in January 2012, says Sri Lankan Power and Energy Minister Patali Champika Ranawaka. When finished, it will be Sri Lanka’s largest hydro facility and should alleviate the country’s energy shortfall.
Ranawaka said he expected the first of two 75 MW generating units to be operating by the end of January, with the second coming online by April.

Activity at RusHydro facilities
The continued investigation of events leading to the deaths of 75 people at Russia’s 6,400 MW Sayano-Shushenskaya plant led to a new round of charges for seven defendants in February 2012, sources report.
An explosion at this plant in early August 2009 killed 75 people and destroyed three of the station’s 10 turbine-generator units, according to plant owner RusHydro.
A report released in October 2009 assigned blame for the failure to several people. An investigation into the accident ordered by then Russian Prime Minister Vladimir Putin was completed in March 2011 and resulted in charges against seven people for safety breaches.
The seven chief executives and officials were charged with violation of labor safety rules (Article 143, Pt. 2 of Russia’s Criminal Code) in 2010, but those cases were only valid for two years given the country’s statute of limitations and included a maximum four-year prison sentence. The new charges could carry up to seven years.
“The defendants will face a new charge under Article 216 for violation of safety rules in mining, construction and other types of operations that entailed the death of two and more people through negligence,” says investigation committee spokesman Vladimir Markin.
Meanwhile, restoration work on the plant continues. RusHydro launched the facility’s fifth hydropower unit in December 2011. This is the first unit to be put on line that is not restored but instead entirely new. RusHydro says it plans to launch three new units annually (including replacements for the four refurbished units) until 2014, at which point the facility’s capacity will have increased from 2,600 MW to 6,400 MW.
Also in December, the European Bank for Reconstruction and Development agreed to provide a long-term loan of RUB8 billion (US$256 million) to fund balance sheet optimization of RusHydro’s subsidiary in Russia’s Far East region.
RusHydro is the world’s second-largest hydropower generator and has signed memorandums of understanding with several developers to expand that capacity even further.
The loan was agreed upon after maturities on local capital markets shrank dramatically due to financial turbulence, according to an EBRD release. The funding will enable RusHydro to go ahead with a planned restructuring of recently-acquired subsidiary OJSC Energy Systems of the Far East, the release said.
Mexico revises law to include large hydro plants
A modification to Mexico’s renewable energy law will broaden the country’s definition of “renewable” to include some of its larger hydroelectric facilities, sources report.
The revised law has been signed by Mexican president Felipe Calderon and amends portions of Mexico’s 2008 energy reform law (LAERFTE). Under the original law, hydropower projects with capacities greater than 30 MW were set apart from other renewables given their larger environmental footprint.
The changed definition means facilities greater than 30 MW will be considered renewable if they have reservoirs with less than 50,000 m3 of water or that occupy less than 1 hectare of surface area.
According to state utility Comision Federal de Electricidad, hydroelectric power accounts for 12.8% of Mexico’s total production, including 41 plants of 30 MW or less for a combined capacity of about 300 MW.
Haiti’s Peligre plant receives IDB grant
Alstom-Comelex has signed a three-year, US$48.4 million contract with the government of Haiti to restore the 54 MW Peligre plant, according to the Inter-American Development Bank.
Peligre’s operator, Electricite d’Haiti, received a $20 million grant from IDB for the project in December 2011.
IDB says the facility operates at a fraction of its potential, forcing Haiti to rely on thermal generators and imported fossil fuels. Restoration of Peligre to its full 54 MW of capacity includes overhauling three turbines and modernizing electromechanical equipment and control systems.
EDH will also upgrade power transmission lines between Peligre and Port-au-Prince using $32 million in IDB grants.
