The 390 MW Dulhasti hydro electric power project, which was hit by delays and cost escalation, will be dedicated to the nation by Prime Minister Manmohan Singh on Saturday.
The foundation stone of the project was laid down by then Prime Minister Indira Gandhi in 1983.
The three-turbine 130 MW project started commercial generation of electricity from March 31, 2007 and is producing electricity more than the expected target, top National Hydroelectric Power Corporation (NHPC) officials told PTI.
The first unit of 130 MWs was successfully synchronised on 28 February, 2007, followed by Unit second of 130 MWs on March 18, 2007 and third unit of 130 MWs on March 26 last year and the project is fully operation since last year.
"It is the most successful unit. Against a target of 1907 Mega Units of power generation, it generated 2210 MUS till March 31st, 2008 from March 31st, 2007 thereby creating a record of 116 per cent achievement", they said.
The project was sanctioned at a cost of Rs 183 crore in 1983 but till now, Rs 5228 crores have been spent on the project, which was undertaken in collaboration with five French partners in 1985.
