The BSES Delhi distribution companies have signed power sale agreements for 25 years with Solar Energy Corporation of India (SECI) to procure 510 MW of solar and hybrid power. Of the total capacity, 300 MW is solar power and 210 MW is wind-solar hybrid power. Further, BSES Rajdhani will be signing the agreement to procure 210 MW of solar and 110 MW of hybrid power while BSES Yamuna will be procuring 90 MW of solar and 100 MW of hybrid power. The power will be available to distribution companies 18 months after signing the agreement at Rs 2.44 per kWh for solar and Rs 2.48 per kWh for hybrid power. The tariff includes SECI’s trading margin of Rs 0.07 per kWh.
The mix of wind and solar is expected to meet Delhi’s power demand, which experiences peak demand twice in 24 hours. The BSES distribution companies expect to use solar power to meet the day peak, while the wind power sourced from the coastal areas is expected to meet the peak demand at night. The agreement will also help the distribution companiesfulfill their Renewable Purchase Obligations (RPO).
