Power producers National Thermal Power Corporation and National Hydel Power Corporation, power trader Power Trading Corporation and the state electricity boards of Himachal Pradesh and Uttaranchal are among the utilities that have evinced interest in supplying power to the Reliance-controlled BSES Ltd.
BSES had invited responses from various utilities having surplus power to cater to demand in the Mumbai area.
The company planned to source around 600 MW of additional power and it had received expressions of interest (EoIs) from over 50 power utilities, sources said.
At present, BSES meets its peak demand of 1,150 MW through its own 500 MW thermal generating station in Dahanu. Around 600 MW is purchased by the company from Tata Power.
The company is the distribution licencee for supplying power to the suburban areas of Mumbai and caters to about 2.23 million consumers at present.
The need for extra power also comes in the wake of BSES having applied to the Maharashtra Electricity Regulatory Commission (MERC) for supplying power to five new distribution zones
