The second phase of impounding at the Koldam, started in November last year has successfully raised the level of the water from 510 to 595 metres till January 3, official sources said.
The current hydro level will be maintained for a month and will be raised only after taking into account various factors, sources said, adding that the dam would be able to generate power by April this year.
It is also one of the initial projects proposed by NTPC when it diversified into hydro power generation. The project was earlier slated for commissioning in 2009.
On reports of the purported leakage at the dam site, PRO of Koldam Parveen Bharti today said that "there was nothing to worry".
"Since the water level has gone up and flow was observed due to recharging of area which would stop shortly," she said.
