ACME Solar signs PPAs for 450 MW/1,800 MWh assured peak power project

Under the PPAs, ACME Solar Holdings will supply 1,800 MWh of assured peak power (450 MW × 4 hours) during non-solar hours from interstate transmission system (ISTS)-connected renewable energy projects in India, with 90% availability on both a monthly and annual basis.

ACME Solar Holdings has signed two long-term power purchase agreements (PPAs) with SJVN for 450 MW/1,800 MWh of assured peak power projects. The agreements were signed through ACME’s subsidiary ACME Greentech Seventh for a period of 25 years.

ACME secured the capacity through tariff-based competitive bidding followed by an e-reverse auction under SJVN’s tender for 6 GWh of assured peak supply (1.5 GW × 4 hours) from renewable energy projects backed by energy storage systems.

The projects will be connected to interstate transmission system (ISTS) substations and will utilize night-time connectivity available with ACME Solar at high irradiation zones in Rajasthan.

Under the PPAs, ACME Solar will supply four hours of assured peak power during non-solar hours, with 90% availability on both a monthly and annual basis.

With these agreements, ACME Solar has signed PPAs for 1,690 MW capacity in the current financial year, taking its total PPA-signed capacity to 6,270 MW.

ACME Solar currently has a diversified renewable energy portfolio of 8,071 MW across solar, wind, storage, firm and dispatchable renewable energy (FDRE), and hybrid projects. Of this, 2,966 MW is operational and 5,105 MW is under construction, along with 17 GWh of battery energy storage system (BESS) capacity. The under-construction PPA-signed portfolio stands at 3,304 MW.
