Solar Power Plants Tenders in India 2026: Market Opportunities, Key Buyers & How to Win

Solar power plants tenders India 2026 — EPC procurement from SECI, NTPC and Railways for contractors and MSME installers

India is the world's third-largest solar market and the fastest-growing, adding a record 44.6 GW of solar capacity in FY 2025–26 alone, according to IndexBox (2026 data). The country's installed solar capacity stood at 143.6 GW as of February 2026, with 42.5 GW of new capacity expected to be added in 2026, driven by government auctions, CPSE-led projects, and PM Surya Ghar rooftop mandates. For EPC contractors, equipment suppliers, O&M service providers, and solar developers, this pipeline translates into a continuous and high-value stream of government procurement tenders. TenderDekho currently lists 26 active solar power plants tenders, spanning ground-mounted utility-scale plants, rooftop systems on government buildings, and hybrid solar-plus-storage projects across India.

Current Landscape

India's solar energy installed capacity reached 122.5 GW in 2025 and is projected to grow to 348.57 GW by 2031, at a compound annual growth rate of 19.05%, according to Mordor Intelligence (2026 data). The ground-mounted solar EPC market alone is valued at USD 8–12 billion (approximately ₹67,000–1,00,000 crores) in 2026, growing at 12–16% CAGR through 2035, per IndexBox (2026 data). Total EPC prices for ground-mounted solar have compressed to approximately ₹3.5–4.5 crore per MW in 2026, driven by record-low module prices and competitive bidding, making projects more financially viable than ever for developers and contractors.

Government agencies issued nearly 6 GW of solar tenders in Q1 2026, almost double the capacity issued in Q4 2025, according to Mercom India (2026 data). The PM Surya Ghar Muft Bijli Yojana has disbursed ₹17,967.53 crore in Central Financial Assistance as of March 2026, targeting rooftop solar installations in one crore households by 2026–27, according to IBEF (2026 data). This creates a parallel procurement stream for smaller EPC contractors and MSME vendors alongside the large utility-scale auction market.

Key Growth Drivers

1. India's 500 GW Renewable Energy Target by 2030

  • What it means: India must add approximately 250 GW of additional capacity from the current 520 GW total installed capacity — the bulk of it solar — to meet its 2030 renewable target, ensuring a decade-long procurement pipeline.
  • Data point: India's total installed power capacity reached 520.51 GW as of January 2026, with non-fossil fuel sources already exceeding 51.93% of the total mix, according to IBEF (2026 data).

2. PM Surya Ghar & Government Building Solarisation

  • What it means: Every government building, institution, and PSU is under mandate to solarise — CPWD, Indian Railways, Defence, and municipal bodies are all issuing tenders for rooftop solar plants ranging from 50 kWp to several MWp.
  • Data point: Over 9.56 GW of rooftop solar capacity was installed under PM Surya Ghar as of March 2026, with 26.19 lakh systems commissioned as of March 19, 2026, according to IBEF (2026 data).

3. PLI Scheme & Domestic Manufacturing Push (ALMM)

  • What it means: The Approved List of Models and Manufacturers (ALMM) mandates the use of domestically listed solar modules in government tenders, creating a parallel supply-chain procurement opportunity for ALMM-compliant module manufacturers.
  • Data point: Two PLI tranches are underwriting more than 48 GW of integrated cell-to-module capacity scheduled to come online by 2026, according to Mordor Intelligence (2026 data).

4. Solar + Storage (Hybrid & FDRE) Tenders

  • What it means: Round-the-clock (RTC) and firm dispatchable renewable energy (FDRE) tenders now require co-located battery energy storage systems (BESS), opening a new high-value EPC segment.
  • Data point: Hybrid solar + storage EPC projects represent 8–12% of the market in 2026, driven by tenders requiring 4–6 hours of battery storage for peak evening demand, according to IndexBox (2026 data).

Year-on-Year Market Projection

Year Installed Solar Capacity (GW) Ground-Mounted EPC (₹ Crores est.) YoY Growth
2024 90 (Est.) 45,000
2025 122.5 67,000 36%
2026 (Est.) 145.8 75,000 12%
2028 (Proj.) 200 95,000 15%
2031 (Proj.) 348.6 1,40,000 19%
