Discuss the role of repowering and hybrid or round-the-clock renewable models in making the best use of India's wind resources.

India has a gross wind potential of 1,163.9 GW at 150 m [2]. Yet installed capacity was only 59.20 GW in September 2026 [1]. Reaching 100 GW by 2030 therefore depends on two things: building new farms, and getting more energy from existing sites and grid lines. Repowering and hybrid/RTC models do the second.

Repowering: more energy from the same land

• The oldest turbines are small and short. They stand on the best wind sites in Gujarat (16,086 MW) and Tamil Nadu (12,273 MW) [3].
• The Repowering Policy, 2023 lets developers replace them with modern turbines. This raises energy output per sq km [4].
• Taller hubs capture more wind. Assessed potential rises from 695.5 GW at 120 m to 1,163.9 GW at 150 m [2].
• Repowered sites already have land and grid lines, so they avoid fresh land and Right-of-Way disputes. Tamil Nadu highlighted its state repowering policy at Windergy 2026 [1].

Hybrid and RTC models: steadier supply

• Wind and solar complement each other. Solar produces only by day, while wind is productive at night [5]. About 45% of wind generation comes during peak-demand hours [2].
• The National Wind-Solar Hybrid Policy, 2018 lets both share land and transmission lines, so each line carries more power [4].
• Storage-linked RTC projects and AI-based forecasting give DISCOMs firm power they can schedule [2]. This reduces the need for coal to cover evening peaks.
• These models also use India's own factories: about 24 GW of turbine capacity, with 70–80% indigenisation in key components [2].

Constraints

• Projects are awarded but not built. Of 4,250 MW of hybrid projects awarded, only 201 MW was running by February 2022 [5].
• Weak RPO enforcement and DISCOM dues of ₹14,247 crore (2022) make projects harder to finance [5].
• Repowering faces fragmented ownership of old sites and a lack of rules for recycling old turbine blades [5].

Way forward

• Penalise developers who walk away from bids, and enforce the separate wind RPO [5][2].
• Extend the 500 MW Contracts-for-Difference pilot to hybrid and RTC projects [2].
• Give repowering an incentive and issue recycling guidelines, as the Standing Committee recommended [5].

Repowering gets more out of existing wind sites, and hybrid/RTC models make wind power steady enough to rely on. Using both lets India reach 100 GW with less new land and a stronger grid. Backed by enforced RPOs and assured payments, they can advance India's net-zero goal and SDG-7 (clean, affordable energy).
