Tata Power to install 100 MW BESS in Mumbai

These will be located in 10 sites.

Tata Power has received approval from the Maharashtra Electricity Regulatory Commission (MERC) to install a 100 MW battery energy storage system (BESS) in Mumbai over the next two years.

In a statement, Tata Power said the system will be installed across 10 sites, especially near load centres across Mumbai Distribution, centrally monitored and controlled from Tata Power’s Power System Control Center.

The BESS will facilitate peak load management to ensure power supply even during high-demand periods. It will also help reduce power purchase costs by storing energy during low-cost periods and utilising it during high-cost peak hours

The facility will also offer ancillary services, including frequency regulation and voltage support, further strengthening grid stability. It will also better utilise solar energy by storing surplus daytime power and making it available during peak demand.

Tata Power said the BESS will be integrated into the Distributed Energy Resource Management System to enhance operational efficiency.
