The Lower Sre Pok 2 scheme is located in Cambodia on the Tonle Sre Pok some 2km upstream of its confluence with the Se San, and about 37km upstream of the confluence of the combined Sre Pok, Se San and Se Kong rivers with the Mekong mainstream. Prefeasibility Study, the project aims to construct and operate an installed capacity 222 MW low head hydroelectric generating facility on the Sre Pok River, generating Annual Energy 1060 GW, Run-of –River dam, reservoir 120km2 Main components include construction of a concrete gravity dam, the powerhouse and generating equipment, environmental and social mitigation measures, and the 220-kV transmission line to Stung Treng and onwards to the Vietnamese border to interconnect with the Vietnamese grid backbone.
The scheme has a much smaller reservoir area (120km’) than the Lower Se San 2 site (355km’) and consequently a lesser environmental impact. The number of inhabitants in the reservoir area for resettlement is also significantly less. The dam is low in height, but could still have a significant impact on navigation and fish migration, which is a particular concern at all sites in this area. Allowances have been made in the scheme design and cost estimate for mitigation of these impacts, so far as is possible.
Per MIME report to RPTCC-4 meeting (Yangon, Sept. 2005), commissioning of 222 MW Lower Sre Pok HPP will be in 2017.
Impact: Up to 1000 people may rewire resettlement[3]
