Insurance Challenges for India's Renewable Energy Sector

India has set a target of 500 GW of non-fossil fuel electricity capacity by 2030, up from approximately 190 GW of installed renewable capacity as of mid-2025. Solar and wind energy dominate, with solar alone targeted at 280 GW. Massive solar parks in Rajasthan (Bhadla), Gujarat (Khavda), and Ladakh, along with offshore wind projects off the coasts of Gujarat and Tamil Nadu, represent billions of dollars in insurable assets.

Every megawatt of installed capacity requires insurance — from construction-phase coverage through operational property and liability policies to performance guarantee instruments. The renewable energy insurance market in India is estimated at over INR 2,000 crore in annual premiums and growing rapidly. However, the sector presents underwriting challenges that differ fundamentally from conventional power generation.

Solar photovoltaic installations face a distinctive risk profile. Physical damage risks include hailstorms (a single severe hailstorm in Rajasthan in 2023 damaged panels across multiple solar parks, generating claims exceeding INR 300 crore), wind damage during cyclones, flooding in low-lying installations, and theft of panels and copper cabling in remote locations.

Technology risk centres on panel degradation, inverter failures, and performance shortfalls relative to warranted output levels. The emergence of newer technologies — bifacial panels, trackers, floating solar — introduces performance uncertainty that historical loss data may not capture. Underwriters must evaluate equipment manufacturer warranties, O&M contractor quality, and site-specific meteorological data when assessing solar risks.

India's wind energy capacity is concentrated in Tamil Nadu, Gujarat, Karnataka, Rajasthan, and Maharashtra — regions that also experience cyclones, high wind events, and monsoon-related flooding. Cyclone Tauktae (2021) and Cyclone Biparjoy (2023) demonstrated the vulnerability of coastal wind installations in Gujarat.

Mechanical failures — gearbox breakdowns, blade damage, generator faults, and tower structural failures — drive the majority of operational period claims. A single wind turbine generator (WTG) gearbox replacement can cost INR 1-2 crore, and blade repair for a 2 MW+ turbine ranges from INR 50 lakh to INR 1.5 crore. Offshore wind projects planned in the Gulf of Khambhat and Palk Strait will introduce marine construction risk, subsea cable exposure, and vessel collision liability — categories of risk with limited domestic underwriting experience.

Renewable energy projects during construction require Erection All Risks (EAR) insurance covering equipment, civil works, and testing/commissioning. The construction phase for a 500 MW solar park in Rajasthan may span 18-24 months with a project value of INR 2,500-3,000 crore.

Key construction-phase risks include: inland transit damage to panels and WTG components (often transported over long distances from ports to project sites in remote areas); storage risks at site during phased installation; testing and commissioning failures; and delay in start-up (DSU) covering revenue loss from construction delays. Lenders — particularly international DFIs and Indian renewable energy-focused NBFCs — mandate comprehensive EAR cover with DSU as a financing condition.

Once commissioned, renewable energy projects require property insurance covering physical damage from natural perils, theft, and accidental damage; machinery breakdown insurance for turbines, inverters, and transformers; business interruption covering loss of revenue from feed-in-tariff or PPA-based power sales; and third-party liability.

Performance risk — the gap between actual generation and projected output — is a critical concern for project lenders and equity investors. Weather index-based parametric insurance products are emerging to cover irradiance shortfall (solar) and wind speed deficit (wind), complementing traditional indemnity-based coverage. These parametric products settle claims based on independently measured weather data, eliminating the need for traditional loss adjustment.

India's renewable energy sector operates within a regulatory framework involving MNRE (Ministry of New and Renewable Energy), CERC and state ERCs (electricity regulatory commissions), and SECI (Solar Energy Corporation of India). Policy risks include tariff renegotiation by state DISCOMs, curtailment of renewable generation, and changes in accelerated depreciation or tax benefits.

While regulatory and political risk insurance is available from multilateral insurers (MIGA) and specialist markets, domestic insurance options for these exposures remain limited. Underwriters should be aware that regulatory actions — such as DISCOM payment defaults or forced curtailment — can create de facto business interruption that falls outside standard policy triggers.

India's energy transition is expanding beyond solar and wind into battery energy storage systems (BESS) and green hydrogen production. The National Green Hydrogen Mission targets 5 million tonnes of annual production by 2030. These emerging technologies introduce new risk categories.

Lithium-ion battery storage facilities face thermal runaway and fire risks that are not well understood by traditional fire underwriters. Green hydrogen production involves electrolysis, hydrogen storage, and transportation — each carrying explosion and process safety hazards. Insurance capacity for these emerging risks is currently limited and expensive. Early movers who develop underwriting expertise in BESS and hydrogen risks will capture a rapidly growing market segment.
