KPCL mulls super critical thermal power plant

Karnataka Power Corporation Limited (KPCL), which is facing frequent shutdowns at the first two units of Raichur Thermal Power Station (RTPS), is looking to set up a 600-800 Mw super critical thermal power station instead of renovating them. The Unit 1 and 2 of RTPS are 26 years old and generate power below their capacity. At present, they together generate around 230 Mw as against 420 Mw.

S M Jamdar, managing director, KPCL, said the cost of renovation of these two units will be close to Rs 400 crore and the setting up of an altogether new unit using super critical thermal technology will cost around Rs 3,000 crore for a 600 Mw unit.

A super-critical plant has a thermal efficiency of 45 per cent, as compared with a sub-critical plant’s efficiency level of 30-38 per cent.

“We had commissioned Bharat Heavy Electricals Ltd (BHEL) to study the health of Unit 1 & 2 of RTPS. BHEL has recommended for renovation and modernisation of these two units to increase their life for further 15 years or go in for a new unit using super-critical technology and set up a 600-Mw project. We are examining both the options and will take a decision within three months,” Jamdar told reporters, here on Thursday. BHEL had supplied the equipment for the first two units of the RTPS.

He said within the existing land in Raichur, the company could set up a bigger project instead of repairing Unit 1 and 2. However, this will result in the closure of both the units for at least two years.

“Given the present power scenario in the state can we afford to shut down these two units, which yield around 230 Mw of power every day?” he pointed out.

KPCL is aware of the present situation and has put off a decision in this regard for the time being and will decide later, he said.
