India renewables: Moody's, ICRA see 38% power by FY30

India’s FY30 renewables projection, and why it matters

Moody’s Ratings and ICRA expect India’s renewable energy share in power generation to rise sharply by FY30, with the agencies pointing to a level of about 38%. ICRA has also referenced renewables surpassing 35% of generation by FY2030, underlining the same directional shift. The core message is that demand and policy support remain strong, but the next leg of growth depends on grid readiness. Transmission constraints, rising grid stress and the execution risk around storage projects are emerging as key friction points. For investors, the story is shifting from only adding capacity to integrating that capacity reliably into the national grid.

Expansion continues, but the bottleneck has moved to infrastructure

India is targeting 500 GW of renewable capacity by 2030, and sector participants expect annual capacity additions of 40-45 GW. As some earlier constraints such as land and financing hurdles ease, grid connectivity and transmission evacuation are becoming the most material constraints. ICRA noted that bidding activity for renewable projects has slowed this fiscal, reflecting execution concerns. It also linked delays in signing power purchase agreements (PPAs) and fewer new bids to worries about available transmission connectivity. This matters because signed PPAs and assured evacuation determine whether commissioned assets can generate stable cash flows.

Grid curtailment is already visible in key states

ICRA highlighted reported grid curtailment in Rajasthan, particularly affecting solar assets during peak generation hours. Girishkumar Kadam, Senior Vice President and Group Head, Corporate Ratings at ICRA, said these events underscore rising strain on existing grid infrastructure as renewable penetration increases. He also pointed to curtailment issues linked to intermittency in states such as Rajasthan and Gujarat. ICRA flagged that curtailment can become more problematic when PPAs do not include compensation clauses. The immediate takeaway is that plant load factors and revenue certainty can be influenced by grid stability actions, even when assets are commissioned.

Stranded capacity and curtailment numbers highlighted by the agencies

Moody’s and ICRA pointed to a growing pool of renewable assets facing offtake and evacuation issues. One cited concern was nearly 44 GW of commissioned renewable capacity that is stuck without formal power purchase or sale agreements. Alongside this, grid constraints were linked to 5-10% curtailment of renewable power during peak hours due to inadequate transmission infrastructure. These figures indicate that the challenge is not only building generation but also ensuring timely contracting and evacuation. They also frame why lenders and rating agencies are closely tracking counterparty strength, contract structures, and grid availability.

Storage is the critical missing layer in the transition

As the renewable share rises, intermittency becomes a grid management issue that requires flexible resources. ICRA and Moody’s emphasised the need to enhance storage capacity and strengthen the grid at both state and inter-state levels. Storage remains a weak link by the numbers cited in the article: battery energy storage capacity is about 0.8 GWh versus a requirement of 236 GWh. That gap illustrates why storage tenders, execution capability, and operating performance are now central to the sector’s next phase. It also explains why curtailment and grid stability actions are being discussed more frequently in ratings commentary.

BESS economics are improving, but execution risk remains

ICRA noted a sharp decline in global battery prices over the past decade, improving storage economics. It cited the current levelised cost of BESS for 2-4 hours of storage at ₹4.0-₹7.0 per unit. ICRA also estimated average battery costs of about USD 70/kWh in 2025, with total project capex at USD 120-150/kWh. On financial metrics, standalone BESS projects were cited as showing a debt service coverage ratio (DSCR) of 1.15-1.25x under current assumptions. Even with improving costs, ICRA flagged that BESS viability remains closely linked to capital costs and that India’s limited operational track record makes performance delivery a key monitorable.

What can go wrong in BESS implementation

ICRA flagged execution and performance risks in the emerging storage segment, including the sector’s limited track record of successful large-scale delivery in India. It also pointed to minimal domestic manufacturing capacity and a shortage of large-scale engineering, procurement and construction (EPC) players, increasing dependence on overseas vendors. Heavy reliance on imported lithium-ion components raises exposure to supply disruptions and potential cost escalation. During operations, ICRA highlighted the risk of failing to meet stringent performance benchmarks, including availability, round-trip efficiency and degradation, alongside strict penalties for delays or underperformance. These are practical risks that can influence project timelines, costs, and long-term cash generation.

Policy support and sector outlook signals

ICRA maintained a ‘Stable’ outlook for India’s renewable energy sector, supported by strong policy backing, competitive tariffs, and rising demand from commercial and industrial consumers. It also referenced government steps such as viability gap funding for storage and extension of transmission charge waivers for such projects till 2028. At the same time, the agency listed persistent challenges including land acquisition hurdles, transmission bottlenecks, delays in PPA signing, volatile equipment costs, and weakened financials of distribution companies. The combined picture is supportive policy intent with execution challenges that can vary by state, offtaker, and technology.

Supply-chain and geopolitical exposure, with China dependency highlighted

The agencies also warned that geopolitical risks continue to matter for India’s clean energy ambitions. ICRA noted that India remains heavily dependent on China for critical solar equipment and battery storage components. This dependence leaves projects exposed to supply disruptions if bilateral tensions escalate. For developers and investors, this risk shows up through lead times, procurement costs, and the ability to commission on schedule. It also reinforces why domestic supply chains and diversified sourcing are strategic issues for the sector.

Market impact: who is affected and what to watch

For renewable developers, transmission availability, PPA timelines, and curtailment clauses become critical drivers of project returns. For transmission and grid-linked companies, the discussion reinforces the need for accelerated evacuation build-outs and grid strengthening at state and inter-state levels. For storage developers and equipment suppliers, the opportunity is growing, but ICRA’s emphasis on performance benchmarks and execution capability raises the bar on delivery and operations. For investors and lenders, the cited stranded capacity, curtailment levels, and dependence on imported components add specific risks to diligence checklists. The near-term theme is not a demand slowdown, but the ability to integrate variable generation reliably.

Conclusion

Moody’s and ICRA see India moving toward renewables contributing around 38% of power generation by FY30, but the path depends on solving grid and storage constraints. ICRA’s commentary on Rajasthan curtailment, transmission bottlenecks, and the large storage gap shows where execution pressure is building. Falling battery prices and policy support such as viability gap funding and transmission charge waivers till 2028 improve the investment case for storage, but performance and supply-chain risks remain central. The next milestones to watch are progress on transmission connectivity, the pace of PPA signings, and the commissioning and operating performance of early large-scale BESS projects.
