BHEL Hyderabad Issues Tender for Integrated Rooftop Solar and BESS Project

Bharat Heavy Electricals Limited (BHEL) issued a tender on May 4, 2026, for the development of a 1.13 MW grid-connected rooftop solar PV system paired with a 4.52 MWh Battery Energy Storage System (BESS) at its Ramachandrapuram facility in Hyderabad. The project is to be executed by a Solar Project Developer (SPD) under a 25-year Build-Own-Operate-Maintain (BOOM) model, providing BHEL with fixed-tariff clean power. This initiative represents a strategic move to integrate large-scale storage with industrial rooftop assets to manage peak demand more effectively.

Technical and Commercial Specifications

• Project Capacity: Installation of an 1130 kWp grid-connected rooftop solar PV system integrated with a 4520 kWh Battery Energy Storage System (BESS).
• Execution Model: Build-Own-Operate-Maintain (BOOM) with a 25-year Power Purchase Agreement (PPA) at a fixed tariff.
• Charging Mandate: The BESS must be charged exclusively via solar power; grid charging is strictly prohibited under any circumstances.
• Operational Requirements: The storage system must be capable of discharging for up to four hours daily during peak demand with a minimum round-trip efficiency of 85% (AC-to-AC).
• Financial Commitments: Bidders must submit an Earnest Money Deposit (EMD) of Rs. 20 lakh and a Performance Bank Guarantee (PBG) of Rs. 60 lakh.
• MSME Benefits: Registered MSMEs under NSIC or Udyog Aadhar are exempt from the requirement to submit the Rs. 20 lakh EMD.
• Selection Mechanism: BHEL will utilize a two-bid system (Techno-commercial and Price) followed by an e-reverse auction to finalize the lowest tariff.

To ensure project viability, BHEL has established rigorous qualification and delivery benchmarks:

• Developer Qualifications: Bidders must demonstrate prior experience with at least 3 MWp in solar projects and 24 MWh in battery storage systems.
• Financial Standing: For the 2024-25 financial year, the developer must have a minimum net worth of Rs. 100 lakh and an annual turnover of Rs. 500 lakh.
• Financial Closure: The successful bidder is required to achieve financial closure within three months from the effective date of the PPA.
• Commissioning Timeline: Full project commissioning must be completed within six months of the PPA effective date.
