TN to strengthen power infrastructure with Japanese aid

Electricity transmission and distribution infrastructure in Tamil Nadu will be strengthened at a cost of Rs 8,000 crore with 56 more sub-stations being set up this year, Chief Minister J. Jayalalithaa announced in the Assembly today.

The sub-stations will improve the quality of power in Chennai, industrial hubs in the State and south Tamil Nadu. Wind power evacuation capacity will also be increased.

She also said the State will enter into long-term, 15-year power purchase agreements through the Case-1 bidding route to bridge electricity shortfall.

Stored hydel power

A 2,000 MW pumped storage hydro power project will be established at a cost of Rs 7,000 crore in the Nilgiris, she said. The Sillahalla hydroelectric project will be established in stages over the next 8-10 years.

In the first stage, a 91-metre high reservoir will be created across the Sillahalla, a tributary of Kundah, and linked to the Avalanche-Emerald reservoirs. In the next stage a 2,000-MW underground power station will be set up between the proposed Sillahalla reservoir and Pillur reservoir 1,500 metres below. The power will be generated when the water flows through an underground tailrace tunnel.
