Discoms have not yet sourced power from the plant this season. But with the temperature rising, they may be left with no choice. The peak demand this year is expected to be about 6200MW.
Currently, discoms are able to source power from other places at a cheaper cost. "The plant functions irregularly because of gas shortage. This raises the cost of power generation. Regular gas supply would bring down the costs substantially. However, the government doesn't run the plant to full capacity and that deters us from sourcing power from it,'' said a discom official.
It is not just the Bawana plant which is suffering because of the gas crisis, Tata Power's 108MW plant in Rithala has become almost redundant because of no gas availability. "We try to source the cheapest power available. If the power produced from Bawana costs about Rs 5-6 per unit, even DERC will ask why we are sourcing power from there when economically viable options are available. Power from Bawana will not become affordable till they have a regular supply of gas,'' said an official. At present, the Bawana plant is in shutdown mode because of which discoms have not sought power from it yet.
The Bawana power project, built at a cost of Rs 4,500 crore, could produce at least 750MW from the first cycle if it had enough gas. But it has barely managed to produce 250 MW since the first cycle was commissioned. Similarly, the proposed power plant at Bamnauli is also stuck as the government has been unable to arrange any gas for the plant, an official said.
Out of the six power stations that supply electricity only to Delhi, four are dependent on gas. Coal-based Indraprastha power station had shut in 2010 and another thermal station-Rajghat powerhouse-with an installed capacity of 135MW is also due to close operations soon. There are also plans to convert three out of five units at NTPC's coal-based Badarpur power station to gas.
"The government is phasing out coal-based power stations for Delhi due to environment concerns. But with gas shortage looming large, production by gas stations is severely limited. There is hardly any gas available in the country and the cost of producing power from imported gas will make it too expensive," said a senior official.
