Tata Power has signed a series of long-term power purchase agreements (PPAs) to strengthen Mumbai’s renewable energy supply. The move follows a sharp rise in electricity demand, with Mumbai and its suburbs recording a peak load of 1,000 MW on October 17 amid soaring temperatures and heavy power use.
25-year PPA with Acme Solar On
On October 16, Tata Power signed a 25-year PPA with Acme Solar Holdings for a 50 MW Firm and Dispatchable Renewable Energy (FDRE) project. The project, combining solar generation with Battery Energy Storage Systems (BESS), will deliver power at a tariff of ₹4.43 per unit.
The agreement includes a commitment to supply four hours of peak-hour power to Mumbai each month, with 90% availability.
Partnership with Juniper Green Energy
In another deal, Tata Power partnered with Juniper Green Energy Limited through its subsidiary, Juniper Green Sigma Eight, for a 70 MW FDRE project in Maharashtra. The facility will integrate 180 MWp of solar and wind capacity with a 280 MWh battery storage system.
Collaboration with Tata Power Renewables
A third agreement, signed with Tata Power Renewables, covers an 80 MW FDRE project combining solar, wind, and advanced battery systems. Expected to generate 315 million units of electricity annually, it will help reduce over 0.25 million tonnes of CO₂ emissions each year.
Tata Power Renewables Signs PPA
Once operational, these projects will allow Tata Power to meet peak-hour demand in Mumbai using firm and dispatchable renewable energy. The initiative will also help the utility meet its Renewable Purchase Obligation, as mandated by the Maharashtra Electricity Regulatory Commission.
