Similar grids are planned for the south and west Delhi, which are under the jurisdiction of BSES Rajdhani Power Ltd (BRPL).
In a major push to clean energy in the national capital, Delhi distribution company (discom) BSES, on Tuesday, announced launch of a pilot project to set up solar micro grids in the east and central Delhi under the jurisdiction of BSES Yamuna Power Ltd (BYPL).
According to a release, similar grids are planned for the south and west Delhi, which are under the jurisdiction of BSES Rajdhani Power Ltd (BRPL).
Micro grids and it’s usage
“These micro grids will combine rooftop solar plants with lithium-ion-based battery energy storage systems. As a technology demonstrator, four such micro grids have been set up at BYPL offices in east Delhi,” the release said.
While the energy generated through rooftop solar plants is being used for catering to the internal power requirements of office loads and to charge batteries, the surplus is fed into the grid, “which has the potential to reduce the electricity bills,” it added.
Noting the multiple benefits of such micro grids, the BSES said the initial results of the pilot project at four BYPL locations have been encouraging. The discom has installed rooftop solar plants, varying between 5 kilowatt (kW) and 7 kW and energy battery storage between 7 kilowatt-hour (kWhr) and 10 kWhr.
“They show that over this period only 8 per cent of grid power (net of exports) was used. The balance 92 per cent was generated and met through the solar plant coupled with the energy battery storage,” the release said.
