NTPC REL Floats 2.1 GW Solar Inverter BoS Tender in Andhra

NTPC Renewable Energy Limited (NTPC REL) has floated two major tenders seeking bids for Balance-of-System (BoS) supply across 2,100 MW of grid-connected solar projects in Andhra Pradesh — creating a massive near-term procurement opportunity for solar inverter OEMs, EPC contractors and component suppliers across India.

The bid submission deadline is June 5, 2026 — giving inverter companies and BoS suppliers roughly four weeks to prepare competitive proposals for one of the largest single-entity solar procurement tenders of the year.

The India Angle: Why This Matters for the Inverter Industry

Balance-of-System is the backbone of every solar installation — and for utility-scale projects, it encompasses the single largest share of inverter procurement in the country. A BoS tender from NTPC REL covering 2,100 MW is effectively a direct order signal for high-capacity string inverters (100 kW+) and central inverters (1 MW+), along with DC/AC cabling, mounting structures, SCADA monitoring systems, and grid integration equipment.

With India targeting 500 GW of renewable energy by 2030, NTPC REL's aggressive tender pipeline shows that the PSU solar buildout has entered high gear. For Indian inverter manufacturers operating under the PLI scheme, this is the kind of demand visibility that justifies capacity expansion.

Key Highlights

• Procuring Entity: NTPC Renewable Energy Limited (NTPC REL) — subsidiary of NTPC, India's largest power utility
• Tender Scope: Two separate tenders for Balance-of-System (BoS) supply
• Total Capacity: 2,100 MW (2.1 GW) of grid-connected solar projects
• Project Location: Andhra Pradesh
• Bid Submission Deadline: June 5, 2026
• BoS Components Include: Solar inverters, mounting structures, DC/AC cables, junction boxes, SCADA/monitoring, grid integration systems
• India Context: Solar now represents 55% of India's total renewable energy capacity as of Q1 2026

What This Means for Inverter Suppliers

This tender directly creates demand for utility-grade inverter solutions. Indian and global manufacturers — including Sungrow, ABB, SMA, Delta Electronics, Growatt, and Waaree — will be targeting this procurement. Domestically-made inverters under PLI will have a preferential edge in public sector procurement.

For inverter dealers and distributors in the Andhra Pradesh region, this signals a major project pipeline coming into construction phase over the next 12-18 months, driving demand for O&M services and spare parts too.

Bidding Opportunity — Act Before June 5

Companies interested must register on the NTPC tender portal. Given the scale (2.1 GW across two packages), early preparation of technical documentation and pricing is essential.
