ACME Solar Signs 450 MW Assured Peak PPAs in 2026

ACME Solar Holdings has reported fresh progress in its assured peak power and renewable-energy project pipeline during 2026. The company said in a March 12, 2026 press release that it signed power purchase agreements, or PPAs, for a 450 MW and 1,800 MWh ISTS-connected assured peak power project. Earlier, on February 6, it announced that it had secured a 301 MW and 1,204 MWh assured peak supply project from SECI.

The announcements add to ACME Solar's stated pipeline of solar, hybrid and firm dispatchable renewable energy, or FDRE, assets. The projects are relevant for India's electricity system because they combine renewable generation with storage or other arrangements intended to supply power during specified peak-demand periods.

Latest PPA announcements

The March 12 disclosure refers to PPAs for 450 MW and 1,800 MWh of ISTS-connected assured peak power. ISTS refers to the interstate transmission system, which allows electricity to be delivered across state boundaries through the national transmission network. The supplied material does not specify the tariff, commissioning schedule, project location or offtaker for this 450 MW project.

ACME Solar's February 6 release described a SECI FDRE project with 301 MW of capacity and 1,204 MWh of energy storage or supply duration. A separate company-news item describes a PPA for 300 MW and 1,200 MWh of assured peak supply with SECI at a tariff of Rs 6 per unit. The source material presents slightly different capacity and storage figures for the SECI award, so the figures should be read in the context of their respective disclosures.

What assured peak supply means

Assured peak power projects are designed to provide renewable electricity when demand is relatively high, rather than only when solar or wind resources are available. Solar generation is generally strongest during daylight hours, while battery storage can shift a portion of that electricity to later periods.

For ACME Solar, such projects broaden the portfolio beyond conventional solar PPAs. The company has also disclosed FDRE projects involving counterparties including SECI, NHPC and SJVN, as well as a hybrid project contracted with NTPC. The mix reflects the growing use of tender structures that seek more dependable clean-power delivery.

Reported PPA-signed capacity reaches 5,380 MW

ACME Solar said its total PPA-signed capacity had reached 5,380 MW following the addition of a 200 MW solar-plus-battery storage project. The supplied material does not provide a date, tariff or offtaker for that particular 200 MW addition.

The company's investor presentation also stated that cumulative FY26 PPA-signed capacity stood at 3,280 MW. Its total under-construction portfolio was stated at 5,081 MW. These figures indicate that a substantial share of the construction portfolio had contracted offtake, although the provided information does not state the commissioning dates for every project.

Andhra Pradesh project advances

ACME Group is also progressing a 400 MW solar and battery storage project in Anantapur, Andhra Pradesh. The project is described as a Rs 3,000 crore initiative intended to provide round-the-clock renewable power. Commissioning is planned for 2026.

The project is expected to support grid stability by pairing renewable generation with battery storage. Andhra Pradesh has indicated its commitment to fast-tracking green projects, according to the supplied project update. No further construction milestones, contracted tariff or offtake details were provided for the Anantapur facility.

Rajasthan hybrid project commissioning

On September 16, 2026, ACME Solar said its subsidiary ACME Renewtech Private Limited commissioned the first phase of a hybrid project at Kelan Village in Bikaner, Rajasthan. Phase I consists of 66.68 MW of solar capacity from a planned 300 MW solar component.

The wider project combines 300 MW of solar power with 100 MW of wind power. ACME Solar said the PPA has been signed with NTPC Limited and long-term project financing has been arranged with PFC. The company described this as its first hybrid renewable-energy project.

Earlier SECI capacity in Jaisalmer

ACME Solar also reported that it commissioned four ISTS-connected SECI projects aggregating 1,023 MW in Jaisalmer, Rajasthan, on December 18, 2024. This earlier commissioning establishes a significant operating base for the company in Rajasthan.

The new PPA announcements are therefore part of a larger expansion across solar, hybrid and FDRE formats. Rajasthan remains an important location in the company's disclosed portfolio, while the Andhra Pradesh project extends its project activity into another major renewable-energy state.

FDRE project pipeline

The investor presentation lists several FDRE projects at different stages. ACME Venus Urja Private Limited has a 400 MW FDRE project with NHPC at Rs 4.64 per unit, with a PPA signed and tariff adoption indicated. ACME Hybrid Urja Private Limited has a 280 MW FDRE project with NHPC at the same stated tariff and PPA status.

Other listed projects include ACME Sun Power's 320 MW FDRE project with SJVN and ACME Urja One's 380 MW FDRE project with SECI, for which the presentation states a PPA for 190 MW. The presentation also shows that regulatory, tariff-adoption and transmission-connectivity processes remain relevant steps for several projects.

Relevance for investors and the power sector

PPAs are central to renewable project development because they establish a contracted offtake arrangement before or alongside construction and financing. The reported additions raise the visibility of ACME Solar's contracted pipeline, but project execution remains dependent on commissioning, transmission connectivity and regulatory processes where applicable.

The Rs 6 per unit tariff cited in the separate 300 MW and 1,200 MWh SECI item is higher than the Rs 4.64 per unit tariff shown for the two 400 MW and 280 MW NHPC FDRE projects in the supplied presentation. However, the projects differ in capacity, tender structure and reported storage obligations, so the figures are not directly comparable.

What to watch next

ACME Solar's next disclosed steps will include progress on the 2026 commissioning plan for the Anantapur project and further execution of its PPA-signed portfolio. Investors will also watch for tariff adoption, connectivity approvals and commissioning updates for the FDRE projects listed in the investor presentation.

The company has reported a larger contracted base and additional assured peak supply agreements in 2026. The available disclosures show continued movement toward solar, hybrid and storage-linked power projects, with future milestones depending on project-level implementation and approvals.
