India’s National Hydroelectric Power Corp. signed agreements March 1 to develop the 495-MW Teesta Stage 4 and 210-MW Lachen hydroelectric projects in North Sikkim District of India’s Sikkim State.
Secretary D.D. Pradhan of Sikkim’s Energy and Power Department signed agreements with NHPC Chairman S.K. Garg, providing for development of the projects on a build-own-operate-maintain basis.
Teesta 4, a run-of-river project proposed for the Teesta River, is to have three 165-MW units.
Lachen, which is to have three 70-MW units, was one of 162 projects whose preliminary feasibility reports were issued by India’s Central Electricity Authority in late 2004. NHPC performed the Lachen PFR along with 42 others.
NHPC already commissioned the 60-MW Rangit project in Sikkim and is building 510-MW Teesta Stage 5 in the state.
