Solarium Green Energy Scales Utility Footprint with ₹186.53 Cr MahaGenco BoS Award

Solarium Green Energy Limited has reached a critical inflection point in its transition toward utility-scale infrastructure, securing a Letter of Award (LoA) from the Maharashtra State Power Generation Company Limited (MahaGenco) on June 22, 2026. The contract, valued at ₹186.525 Crore (excluding GST), appoints Solarium as the subcontractor for a ground-mounted solar PV project with a capacity of 50 MW AC (65 MW DC). This engagement signifies Solarium’s successful entry into the MahaGenco ecosystem, marking a strategic pivot from its established leadership in the residential rooftop segment toward complex state-utility mandates.

Project Specifications and Financial Parameters

The project is situated at a brownfield site—the Parli Thermal Power Station (TPS) Old Units 1-5—and involves sophisticated integration with the state’s high-voltage transmission network.

Technical Scope and Maintenance Mandate

While the contract is framed within the broader Engineering, Procurement, and Construction (EPC) framework, the technical specifications of the MahaGenco tender define the work as a Balance of System (BoS) package.

• BoS Execution Scope: The mandate encompasses end-to-end engineering, procurement, inspection, erection, construction, and commissioning. Crucially, as a BoS contract, the scope excludes the supply of PV modules, IDTs, and central inverters, focusing instead on the heavy infrastructure and power evacuation systems.
• Power Evacuation: Solarium is responsible for the associated power evacuation system up to the MSETCL STU Substation at 33 kV or above.
• Operations & Maintenance (O&M): The LoA specifies a 36-month (3-year) O&M period following commissioning. While this reflects the immediate contract obligation, it sits within a utility landscape where MahaGenco traditionally seeks 7-year maintenance cycles, providing potential for future service extensions.
• Commercial Viability: The contract value is optimized by the recent reduction in GST rates on solar components from 12.5% to 5%, improving the project’s overall commercial footprint.

Corporate Context and Market Synthesis

This award represents a transformative expansion for Solarium Green Energy. The contract value of ₹186.53 Crore constitutes approximately 50% of the company’s reported FY26 revenue of ₹368 Crore. Prior to this win, Solarium’s unexecuted order book stood at over ₹300 Crore; this award bolsters that total to an estimated ₹480+ Crore, providing robust revenue visibility through FY28.

Solarium is leveraging an “asset-light” execution model typical of high-growth specialized EPC players, allowing for rapid scaling without the balance-sheet burden of long-term Power Purchase Agreements (PPAs). Though this specific project excludes module supply, Solarium’s 1.2 GW automated module manufacturing capacity in Ahmedabad provides a strategic buffer. This vertical integration likely enhanced the company’s bidding competitiveness and reinforces its standing as India’s second-largest residential solarisation vendor—a reputation now being utilized to capture high-margin utility-scale construction mandates.

Compliance and Execution Timeline

In accordance with Regulation 30 of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015, the company has formally notified the Bombay Stock Exchange (BSE) of the award.

The project is slated for a 24-month execution window from the date of the LoA. Given the June 2026 award date, the project secures steady earnings conversion through the mid-term, aligning with Maharashtra’s aggressive renewable energy deployment targets and the company’s stated objective of diversifying its project mix toward large-scale government infrastructure.
