India's C&I Renewable Energy Capacity Poised for Significant Growth Amidst Policy Tensions
India's commercial and industrial (C&I) sector is on track to significantly expand its renewable energy (RE) capacity, with projections indicating a rise to 57 gigawatts (GW) by fiscal year 2028, a substantial increase from the estimated 40 GW by the end of FY26. This aggressive growth trajectory, an addition of 17 GW in just two years, is primarily propelled by corporate decarbonization mandates and the pursuit of tariff arbitrage opportunities. The implementation of the Green Energy Open Access (GEOA) Rules, 2022, has been a critical enabler, empowering industrial and commercial entities to directly source renewable power through existing grid infrastructure.
The Dual-Edged Sword of Open Access Incentives
The expansion is largely anchored by favorable long-term Power Purchase Agreement (PPA) tariffs compared to grid tariffs, corporate net-zero commitments, and renewable purchase obligations (RPOs). Gautam Shahi, Director at Crisil Ratings, highlights that states are actively offering incentives such as rebates on cross-subsidy, wheeling, and state transmission utility charges for intra-state power procurement. These measures can reduce the landed cost of power by 25-30% relative to on-grid tariffs, thereby driving capacity additions. Energy-intensive sectors, including steel, cement, and data centers, are at the forefront, aligning their operations with net-zero targets and RPO compliance. Private equity-backed developers are expected to lead incremental additions, attracted by higher return on equity in C&I projects compared to utility-scale endeavors, supported by better tariffs and robust counterparties. Dushyant Chauhan, Associate Director at Crisil Ratings, notes the strong credit profile of the C&I portfolio, characterized by attractive tariffs and an average PPA tenure of around 15 years, ensuring stable revenue visibility, with 65% of rated capacity tied to high-credit-profile counterparties.
The Looming Threat of Policy Recalibration and DISCOM Finances
Despite the optimistic outlook, significant risks cloud the sector's future. Infrastructure limitations, particularly constrained intra-state transmission capacity and right-of-way issues, have emerged as critical bottlenecks impacting project timelines. More fundamentally, states face a delicate balancing act. The incentives designed to promote open access renewable energy can directly reduce the revenue streams for distribution utilities (DISCOMs), which rely on high-paying C&I consumers for profitability. As of FY25, DISCOMs have reported a positive Profit After Tax of ₹2,701 crore, a turnaround from substantial previous losses, due to factors including reduced losses, automatic cost adjustments, and a revamped distribution sector scheme. However, the financial health of DISCOMs, while improving, remains vulnerable, withAggregate Technical and Commercial (AT&C) losses still significantly higher than global averages. Any recalibration of open access incentives, potentially driven by the need to protect DISCOM finances, could lead to increased landed power costs for end-users, though tariffs are expected to remain competitive against grid supply. The regulatory landscape also presents challenges, with slow adoption of Green Open Access Rules at the state level and varying open access charges, making project approvals and operationalization complex.
Sectoral Dynamics and Future Projections
The C&I segment is a cornerstone of India's ambitious target of achieving 500 GW of non-fossil fuel-based capacity by 2030. Analysts project significant investment, estimated at $350 billion over five years for renewable energy and infrastructure to reach the 500 GW target. The growth is underpinned by falling RE costs, with solar tariffs dropping to approximately ₹2.50 per unit from ₹11-12 a decade ago. Average grid tariffs for industrial consumers range from ₹6 to ₹8 per unit, while renewable energy through open access or PPAs can be secured at ₹3-4.5 per unit, creating a substantial arbitrage. The open access market's share in solar and wind installations grew from 5% in 2019 to 34% by 2024. India's total installed capacity of renewable energy reached approximately 242.63 GW by August 2025, with solar leading at 123 GW. The government's commitment is further evidenced by a significant increase in budgetary allocations for the Ministry of New and Renewable Energy. Storage-backed renewable energy capacity is also projected to expand significantly, reaching 25-30 GW by FY28, playing a crucial role in addressing intermittency.
