Hydropower dams in Myanmar

Salween River downstream of Weigyi Dam site

Salween River and watershed

Seven dams have been proposed for the Salween River. The largest of these hydro power projects is the 7,100 megawatts (9,500,000 hp) Tasang Dam on the Salween River, which is to be integrated into the Asian Development Bank's Greater Mekong Sub-region Power Grid. A groundbreaking ceremony for the Tasang Dam was held in March 2007, and China Gezhouba Group Co. (CGGC) started preliminary construction shortly after. China's involvement in the damming of the Salween River is not limited to the Tasang project.

In 2006, the government signed a Memorandum of Understanding (MoU) with Sinohydro for the US$1 billion, 1,200 MW Hat Gyi Dam along the Thai border. In April 2007, Farsighted Group (now known as Hanergy) and China Gold Water Resources Co. signed MoUs for an additional 2,400 MW hydropower project on the upper Salween, an area which Yunnan Power Grid Co. reportedly surveyed in 2006.

In April 2008, Sinohydro, China Southern Power Grid Co., and China Three Gorges Project Co. signed a strategic cooperation framework agreement for the development of the hydro power potential of the Salween River. Despite China's involvement in these large-scale dams on the Salween, most of the electricity is destined for export to neighboring Thailand.

However, In May 2009, Chinese Premier Wen Jiabao halted the construction of the Liuku dam on the Salween River in China's Yunnan province, calling for more thorough impact assessments.[10]

The 1,420 megawatts (1,900,000 hp) Shweli I, II, III Cascade, in Shan State near the Chinese border, has also received significant Chinese support. Yunnan Machinery and Equipment Import and Export Co. (YMEC) began work on the Shweli I Hydropower Plant in February 2004 and, following the government's inability to secure funding, joined with Yunnan Huaneng Lancang River Hydropower Development Co. and Yunnan Power Grid Co. to create the Yunnan Joint Power Development Company (YUPD) in August 2006. For more information regarding the Salween River, see [A 1].

A few months later, YUPD assumed an 80% share in the project after creating the Shweli River I Power Station Co. together with Myanmar, turned the Shweli I dam into a Build-Operate-Transfer (BOT) project, and increased the installed capacity from 400 to 600 MW. At least two Sinohydro subsidiaries have provided construction services for the project, and Sichuan Machinery & Equipment Import & Export Co. and Ningbo Huyong Electric Power Material Co. have signed US$ multimillion contracts for electricity transmission cables and towers. The Shweli I Hydropower Plant is slated for completion by June 2009, and was half complete as of May 2007.

In Kachin State, several Chinese MNCs are involved in the construction of seven large dams along the N'Mai Hka, Mali Hka, and Irrawaddy River, with a combined installed capacity of 13,360 megawatts (17,920,000 hp) In 2007, China Power Investment Co. signed agreements with Burmese authorities to finance all seven dams, as well as with China Southern Power Grid Co. Yunnan Machinery & Equipment Import & Export Co. (YMEC) signed an MoU with Myanmar's Ministry of Electric Power in 2006 to develop the hydropower potential of the N'Mai Hka. However, details of this arrangement remain unclear. Changjiang Institute of Surveying, Planning, Design & Research has also completed a feasibility study at the confluence of the N'Mai Hka and Mali Hka.

In western Myanmar, just inside the Indian border, runs the Chindwin River, where several potential dam sites have been identified that are likely to service export-oriented hydro-power plants. The sites include Thamanthi, Mawlaik, Homalin, and Shwezaye.[11]

In August 2001, the Kansai Electric Power Company, or KEPCO, contracted with Myanmar to provide technical assistance for developing 12 hydro-power plants, including at least five sites on the Sittang River Yenwe, Khabaung, Pyu, Bogata and Shwe Gin.[6]

China CAMC Engineering Co. has been involved in the surveying and implementation of hydropower projects in the region. The 790 MW Yeywa Dam in Mandalay Region, which began construction in 2006, is also being financed and constructed by several Chinese MNCs, including China Gezhouba Group Co., Sinohydro, China International Trust and Investment Co. (CITIC) Technology Co., ChinaNational Electric Equipment Co., China National Heavy Machinery Co., and Hunan Savoo Oversea Water and Electric Engineering Co. Additional financial backing for the project is being provided by the China EXIM Bank.

In addition to the Yeywa, Shweli and Hat Gyi projects, Sinohydro China's largest dam company and its subsidiaries have been involved in the Kun Creek-2, Kyauk, Monechaung, Nam Hkam Hka, Paunglaung (upper & lower), Tarpein I, Thapanseik I, II, III, and Zawgyi I Dams. As with the Yeywa project, both CITIC and China EXIM Bank provided investment and financial backing for the Thapanseik Dam.

The Yunnan Machinery & Equipment Import & Export Co. (YMEC) has been one of the most active Chinese companies in Myanmar's hydropower sector. Since the 1990s, YMEC has been involved in more than 25 projects of varying size, including the Ching Hkran, Chinshwehaw, Dattawgyaing, Hopin, Kunhein, Kunlon, Kyaing Ton, Kyaukme, Laiva, Mepan, Nam Hkam Hka, Nam Myaw, Nam Wop, Nancho, Paunglaung, Upper Paunglaung, Shweli I, II, III Cascade, Watwon, Zaungtu, Zawgyi I and II, Zichaung, and N'Mai Hka River hydropower projects, as well as the Rangoon Dagon Substation. The extent of YMEC involvement in these projects, several of which are completed, is unclear, but appears to involve construction and some financing.[A 2]

In addition there were at least 10 major irrigation dams completed during the period between 1962 and 1988.[2]
