NHPC to complete Teesta VI hydropower project in Sikkim

SILIGURI: State-owned NHPC Limited has bagged the responsibility to complete Teesta VI hydropower project years after the initial builder – Lanco Teesta Hydro Power Ltd (LTHPL) – went into insolvency and the 500 mw project hit a roadblock.

The Cabinet Committee on Economic Affairs (CCEA) headed by the Prime Minister has approved the investment sanction for acquisition of LTHPL and execution of the remaining work by NHPC.

“It is a big responsibility that we are happy to shoulder. With only around 30 per cent job done, the project will now require new planning and execution including situation analysis and fresh tendering,” said Debajit Chattopadhyay, executive director, NHPC.

According to officials, the project will be implemented at an estimated cost of Rs 5,748.04 crore, which includes the bid amount of Rs 907 crore for acquisition of LTHPL.

The run of the river project in Sirwani village is aimed at utilising the power potential of Teesta river basin. It envisages construction of a 26.5 metre high barrage across the river, two horse shoe shape head race tunnels of 9.8 metre diameter and 13.76 km length, and an underground power house with four generation units of 125 mw each.

The project is expected to generate 2,400 million units of power in a year when the annual generation has the probability of being equal to or exceed 90 per cent of the time on annual basis during the expected period of operation of the scheme. While 12 per cent of this output will go to the host state Sikkim as royalty, the rest will be taken to the national power field.

NHPC has set a deadline of five years for the completion of project. “We do not apprehend any chance of cost or time overrun on this. But geological surprises and natural calamities may alter the scenario,” said Chattopadhyay.
