DJB looks at harnessing solar energy potential for running its installations

In order to reduce expenditure on account of electricity bills, the Delhi Jal Board (DJB) is looking at solar power as an alternate source of power for running its installations.

The DJB proposes to install Grid Connected Roof top Solar PV system at its different installations and use the generated electricity for running the installations.

A Solar photovoltaic system is a power system designed to supply usable solar power by means of photovoltaics. It consists of a parallel arrangement of solar panels to absorb and convert the sunlight into electricity.

The proposed capacity of the Solar PV on the rooftops of available areas at various installations of the water sector of DJB is 16,000 Kilowatts peak. It is estimated to generate 2.1 Crore units annually which will eventually lead to an annual saving of Rs. 3 Crores on DJB's budget.

The phase-I of the project includes the installation of grid connecting rooftop Solar PV at the Haiderpur Water Treatment Plant (WTP), Sonia Vihar WTP, Bhagirathi WTP, Bawana WTP, Iradat Nagar Raw Water Pump House (RWPH), Bawana RWPH & RWPH at Yamuna for Bhagirathi, Sonia Vihar WTP and various Booster Pumping Stations.

The focus on harnessing the potential of solar energy is estimated to cut down DJB's O & M costs for a period of 25 years .

The phase - II of the implementation of Grid Connected Roof top Solar Photo Voltaic (PV) system is proposed to extending the project includes 25 years of comprehensive operation and maintenance at various Sewage Treatment Plants and Booster Pumping Stations.

While in phase-III, the project will be extended to include the installation of the grid connected rooftop solar PV system at various unused open land of Sonia Vihar WTP, Iradat Nagar Raw Water Pump House and Dwarka WTP and other vacant lands of DJB. Comprehensive operation and maintenance for 25 years will also be part of the project.
