New Delhi: Public sector construction major, the Central Public Works Department (CPWD), will generate 42.50 MW of solar energy across the country besides replacing energy inefficient electrical fittings in 20 government buildings in Delhi by September and in the rest of the country subsequently. These initiatives of CPWD are estimated to result in a total saving of Rs 115 crore per year.
Efforts of the CPWD and the consequent gains in terms of savings in energy consumption were reviewed today by Madhusudhan Prasad, secretary at the Urban Development Ministry.
The CPWD had earlier signed a Memorandum of Understanding (MoU) with the Solar Energy Corporation of India (SECI) for generation of solar power for installation of grid connected rooftop solar photo-voltaic panels in all government buildings maintained by CPWD across the country. Consequently, SECI awarded works to 14 bidders for undertaking works in 16 States.
Solar power of 10 MW will be generated by May in Phase I covering Delhi (3 MW), Uttar Pradesh (2 MW), Northeast and Union Territories (2 MW) and 1 MW each in Andhra Pradesh, Karnataka and Maharashtra.
In Delhi, Solar panels have already been installed for a total capacity of 1.50 MW over 6 government buildings namely Nirman Bhawan, Shastri Bhawan, East Block and Sewa Bhawan (RK Puram), Pushpa Bhawan near Sheik Sarai and CGO Complex, Lodhi Road. During the last 3 months, a total of 2,86,100 units of power has been generated from these installations resulting in a saving of Rs.11.50 lakhs in energy cost. Generation of 42.50 MW of solar power is estimated to result in a saving of Rs.13 cr per year.
Prasad has directed CPWD and SECI to ensure net metering at all the 200 buildings in the country to ensure proper monitoring of net energy consumption by government buildings.
As part of measures to promote efficient use of energy in all the government buildings, CPWD has begun to replace energy inefficient fittings with LED bulbs and 5-star air conditioning systems approved by the Bureau of Energy Efficiency. This will be completed in 20 buildings in Delhi by September.
These measures are estimated to result in a total saving of 11.41 crore units of power and Rs 103 crore in energy cost per year.
In Delhi, 16,613 LED lamps have so far been installed in 261 of 268 government bungalows and 408 of 546 flats of MPs. The remaining will be done so during the Budget session of Parliament.
