ACME Solar Signs 300MW Peak Power PPA With SECI

ACME Solar has signed a power purchase agreement with the Solar Energy Corporation of India for 300MW of peak power capacity, the company said. Energy Monitor reported the signing on 19 October 2026.

The agreement is for peak power, a category SECI has been tendering separately from plain round-the-clock or daytime solar contracts. Peak power typically means supply during the evening hours when demand climbs and solar output falls away.

ACME did not disclose the tariff, the location of the project, or the expected commissioning date in the announcement. SECI has not published the signed agreement either.

Why peak power is a different contract

Most Indian solar PPAs are built around daytime generation. Peak contracts ask for power at hours when the sun isn't doing the work, which usually means pairing solar with storage or another source. That pushes up cost, and it changes how a developer designs the plant.

SECI has run several peak and round-the-clock tenders over the past few years. Developers have been cautious. Storage remains expensive, and tariffs discovered in some of these auctions have come in higher than plain solar.

ACME Solar is one of the larger independent renewable players in the country, with operating and under-construction capacity spread across several states. The company listed on the exchanges in 2024. Its order book has leaned on SECI contracts before.

What the deal doesn't say

Three things a reader would want are missing. The tariff. The battery capacity, if any. The site.

Those gaps matter. A 300MW peak contract without storage is hard to serve. With storage, the economics depend heavily on what SECI agreed to pay per unit and how the capacity is charged.

SECI signs PPAs on behalf of discoms, which then buy the power. A signed PPA is a step, not a finished project. Financial closure, land, transmission connectivity and module supply all still have to fall into place.

The announcement lands in a busy stretch for Indian solar. Installations have been climbing, module prices have stayed soft, and the government has kept pushing storage-linked tenders. Peak power sits at the centre of that push.

ACME's shares have been volatile since listing. Analysts have flagged execution and use as things to watch. A 300MW peak contract adds to the pipeline, but the market will want the tariff before it can judge whether the deal makes money.

GreenEarth News has asked ACME Solar and SECI for the tariff and project details. Neither had responded at the time of writing.
