BEST Signs 25-Year Solar Power Deal With SECI

Mumbai's Brihanmumbai Electric Supply and Transport (BEST) undertaking has signed a 25-year power purchase agreement with the Solar Energy Corporation of India (SECI) for 220 MW of solar power. The agreement, signed on August 31, will provide BEST with solar power at Rs 2.87 per unit.

The deal includes a 110 MW/440 MWh Energy Storage System (ESS), which will help store electricity and make it available during periods of high demand. BEST General Manager Dr Sonia Sethi signed the agreement along with SECI Executive Director Atulya Naik and Deputy General Manager Sanjeev Singh.

The renewable energy will be sourced from various renewable energy project developers in Maharashtra. This agreement is part of BEST's efforts to meet its Renewable Purchase Obligation (RPO) targets and reduce its dependence on conventional sources of power.

At present, BEST meets around 33 per cent of its total electricity requirement of nearly 1,000 MW through renewable sources. With the addition of the new solar power capacity, the share of green energy in its overall power mix is expected to increase to 43 per cent.

The project is also expected to help BEST manage its electricity costs during the evening peak, when demand in Maharashtra is at its highest. The energy storage system will allow power to be stored and supplied during these peak hours, helping the undertaking access electricity at comparatively lower rates.

The move is expected to lower carbon emissions and strengthen BEST's long-term transition towards cleaner energy sources. This deal is a significant step towards expanding BEST's green energy portfolio and reducing its dependence on conventional power sources.

The agreement will provide numerous benefits to BEST, including reduced power procurement costs and lower carbon emissions. The energy storage system will also help manage peak demand, ensuring a stable and reliable power supply to consumers.

In addition to the environmental benefits, the deal will also contribute to Maharashtra's renewable energy goals. The state has set ambitious targets for renewable energy, and this agreement will help BEST play a significant role in achieving these goals.

Overall, the 25-year solar power deal between BEST and SECI is a major step towards a sustainable and environmentally friendly future for Mumbai. It will not only reduce BEST's dependence on conventional power sources but also contribute to a cleaner and healthier environment for the city's residents.

The deal is expected to have a positive impact on Mumbai's environment and economy, and it will be interesting to see how it unfolds in the coming years. With this agreement, BEST is taking a significant step towards a greener and more sustainable future, and it is likely to set an example for other cities to follow.

In conclusion, the 25-year solar power deal between BEST and SECI is a major milestone in Mumbai's transition towards renewable energy. It will provide numerous benefits, including reduced power procurement costs, lower carbon emissions, and a more stable and reliable power supply. The deal is a significant step towards a sustainable and environmentally friendly future for Mumbai, and it is likely to have a positive impact on the city's environment and economy.
