ACME Solar Unit Signs 130 MW PPA with Northeast Frontier Railway

GURUGRAM, India — ACME Solar Holdings Limited announced on Wednesday, August 26, 2026, that its wholly owned subsidiary, ACME Marigold Urja Private Limited, has executed a Power Purchase Agreement (PPA) with Northeast Frontier Railway (NFR). The regulatory disclosure submitted to Indian stock exchanges specifies the development of a 130 megawatt (MW) Round the Clock (RTC) renewable energy power project.

The contract was formally awarded by REMC Limited, a joint venture of Indian Railways and RITES Limited, to supply firm, continuous clean electricity across the regional rail network. The development is a major milestone in Indian Railways' strategic program to decarbonize train operations and transition away from fossil-fuel-based grid supply.

Technical Specifications and Financial Framework

Under the terms detailed in the corporate regulatory filing, ACME Marigold Urja Private Limited will construct, operate, and maintain the 130 MW RTC renewable facility for a quarter-century duration. The tariff structure is fixed at ₹4.35 per kilowatt-hour (kWh) for the entire 25-year operational lifecycle.

The primary commercial terms of the Power Purchase Agreement include:

• Project Capacity: 130 MW Round the Clock (RTC) renewable energy supply.

• Awarding Entity: REMC Limited.

• Offtaker Entity: Northeast Frontier Railway (NFR).

• Fixed Tariff Rate: ₹4.35 per kWh applicable across each year of the PPA tenure.

• Commercial Operation Timeline: Scheduled Commencement of Supply Date (SCSD) set for February 25, 2029.

• Operational Duration: 25 years from the official SCSD date.

• Transaction Nature: Domestic corporate contract executed at arm's length, with no promoter group interest involved.

Accelerating Railway Decarbonization and Energy Security

The 130 MW RTC project design ensures continuous clean power supply by integrating solar, wind, or energy storage technologies, avoiding the intermittency limitations of single-source renewable installations. Round-the-clock power supply contracts are critical for traction power demands, where continuous energy availability is essential for daily train schedules across the Northeast region.

By securing a long-term fixed rate of ₹4.35 per kWh, Northeast Frontier Railway insulates its operating budget against volatile fossil fuel pricing and shifting market tariffs. The initiative supports the broader mission of Indian Railways to achieve net-zero carbon emissions, serving as a template for state-owned transport networks seeking large-scale clean energy adoption.

For ACME Solar Holdings Limited, the project execution strengthens its institutional portfolio of long-term utility-scale PPAs, providing clear revenue predictability through early 2054.
