Lake-tapping at Koyna to beef up power supply


An indigenous lake tapping aimed at providing uninterrupted water supply was carried out at the Koyna hydro- electric project in Satara district on Wednesday at the hands of Chief Minister Prithviraj Chav


The tapping is aimed at generating an additional 1,185 million units of electricity every year and will ensure that the fourth stage of the Koyna project continues to operate uninterrupted.

This will also help to supply water to drought- hit areas of Satara. The State aims to be free of power outages by the end of 2012.

Though the first such tapping was done with the help of foreign experts, the second experiment on Wednesday was fully designed and implemented by engineers of state governments Water Resource Department. The second such procedure was after a gap of 13 years.

The Koyna project generates 1960 MW of power and the lake- tapping will provide additional 15 TMC water to the Krishna Valley projects.

Chavan, who hails from Satara district, Deputy Chief Minister Ajit Pawar and Water Resources minister Sunil Tatkare witnessed the event.

Deputy Chief Minister Ajit Pawar said that this was a major step towards making Maharashtra selfsufficent in energy.

” By December ( 2012), Maharashtra will be totally free of load- shedding,” Pawar assured.

The first lake tapping was conducted on March 13, 1999 during the Shiv Sena- BJP regime in the state.

Chavan pressed a button which blasted the rock cover of tunnel and a wave of water in Shivsagar lake was created. This water entered into the tunnel.

” Now, the additional water stored in Koyna dam could be utilised as the second lake tapping was conducted at a depth which was 12 metres lower than the first lake tapping,” Chief Engineer ( Civil- Hydro Projects), Deepak Modak said.

” The first lake tapping was done with the help of Norwegian technology, while this one was carried out by experts of the state Irrigation Department,” he said.

The Koyna Dam was commissioned in the year 1962 and is the main supplier of electricity to the state.

Will help additional power generation and water supply for drought- affected areas
