Indian power distributor BSES Yamuna is to partner Panasonic in rolling out pilot solar power microgrids with battery storage at four separate locations in East Delhi.
Each microgrid will comprise 5-7kW of rooftop solar generation and 7-10kWh of lithium-ion battery storage.
The pilot plants set up at BSES offices in East Delhi reported that, following installation, locations sourced 92% of their power from the microgrid, and only 8% from the grid itself.
BSES said this results in an annual consumption reduction of ~1,245 litres of diesel and ~240,000 units of electricity, together amounting to savings around Rs 20 lakh (US$29,000).
Extrapolated over 1,000 installations, this means that a wide rollout of microgrids has the “potential to save up to 62 million units of electricity and 51,000 tonnes of carbon dioxide”.
BSES Yamuna Power was formed in 2002 as a joint venture between Reliance Infrastructure and the government of the National Capital Territory of Delhi.
A BSES spokesperson said: “The installation of microgrid applications as part of the [the company’s] green division initiative would act as a showcase for customers to adopt and help in preserving (the) environment through a reduction in carbon footprint.”
Last month, “India’s first grid-scale battery-based storage system” was inaugurated by AES and Mitsubishi in Rohini, Delhi.
