Waaree Renewable Technologies Ltd Signs Major 350MW BESS EPC Contract

Waaree Renewable Technologies Ltd has secured a significant turnkey EPC contract for a 350MW/1400MWh Battery Energy Storage System (BESS) project. The deal includes two years of operation and maintenance (O&M) services, with completion targeted by FY 2026-27.
Reader Takeaway: Large BESS order boosts portfolio; related-party risk needs careful management.

What just happened (today’s filing)

Waaree Renewable Technologies Limited (WAAREERTL) announced on May 18, 2026, that it has signed a turnkey contract for a substantial 350MW/1400MWh Battery Energy Storage System (BESS) project.

The contract encompasses the full spectrum of Engineering, Procurement, and Construction (EPC) works.

It also includes a two-year operation and maintenance (O&M) services component.

The project is being executed in collaboration with Waaree Forever Energies Private Limited (WFEPL), a subsidiary of WAAREERTL, and is slated for completion by the Financial Year 2026-27.

Why this matters

This development marks a significant stride for WAAREERTL in the rapidly growing energy storage sector, a critical component for grid stability and renewable energy integration.

Securing such a large BESS EPC contract underscores the company's expanding capabilities beyond traditional solar EPC.

It diversifies their order book and positions them to capitalize on India's increasing demand for energy storage solutions.

The backstory (grounded)

WAAREERTL has established itself as a key player in India's renewable energy landscape, primarily through large-scale solar EPC projects.

The company has been strategically broadening its expertise to include advanced energy storage systems like BESS, recognizing its growing importance.

Waaree Forever Energies Private Limited (WFEPL) is an internal subsidiary, enabling WAAREERTL to leverage group synergies and streamline project execution.

What changes now

• Expansion of WAAREERTL's project portfolio into a high-growth BESS segment.
• Potential for increased revenue streams from both EPC execution and O&M services.
• Strengthened position in the Indian energy storage market.
• Demonstration of execution capability for significant BESS projects.

Risks to watch

• The contract involves a related party, WFEPL. While stated to be at 'arm's length,' ongoing vigilance to ensure all terms and execution remain at arm's length is crucial.

Peer comparison

WAAREERTL competes in a space with established players like Sterling and Wilson Renewable Energy Ltd and Larsen & Toubro Ltd, both of whom are also active in renewable EPC and energy storage solutions.

These peers also possess significant capabilities, highlighting the competitive nature of securing and executing large infrastructure projects in the energy sector.
