India's Energy Transition: Strategic Reallocation and the Rise of Renewables

India's energy landscape is undergoing a seismic shift. By 2025, solar power has surged to 10% of the country's electricity generation, with renewables accounting for 23.3% of total output. This marks a pivotal moment in the nation's energy transition, as coal—once the backbone of India's power grid—faces declining demand. For investors, this transformation presents both opportunities and risks. Energy utilities and coal suppliers are reallocating assets to renewable infrastructure, but the long-term viability of coal-dependent firms remains uncertain.

The Shifting Energy Mix

India's coal dependency has long been a cornerstone of its energy strategy, with coal accounting for 75% of electricity generation in 2025. However, the rapid expansion of solar and wind power is reshaping this dynamic. Solar generation alone grew by 32.4% in the first four months of 2025 compared to 2024, driven by a 30% increase in installed capacity. Clean energy now meets 23% of India's electricity needs, a record high. This shift is not just environmental—it's economic. Renewable energy is now cheaper than new coal power, with solar and wind projects offering electricity at 3.5–4.5 rupees per kWh, compared to 6–7 rupees for coal.

The government's policy push is accelerating this transition. Initiatives like the PM Surya Ghar Yojana (rooftop solar) and the Production-Linked Incentive (PLI) scheme for solar manufacturing are creating a fertile ground for investment. By 2030, India aims to achieve 500 GW of non-fossil fuel capacity, with renewables expected to grow at 10% annually.

Strategic Reallocation: Winners and Losers

Energy utilities and coal suppliers are pivoting to renewables, but the pace and scale of reallocation vary. NTPC Green Energy, a subsidiary of India's largest coal-fired utility, NTPC, has committed $9.59 billion to green hydrogen, ammonia, and solar projects in Maharashtra. This aligns with NTPC's goal of building 60 GW of renewable capacity by 2032—a stark departure from its coal-centric legacy.

Similarly, Tata Power is investing $8.42 billion to develop 10 GW of solar and wind projects in Tamil Nadu, aiming for 70% clean energy by 2030. Torrent Power, Gujarat's major utility, has pledged $5.7 billion to renewable energy and green hydrogen, while BPCL is targeting 10 GW of renewables by 2035. These moves reflect a broader trend: utilities are repurposing coal sites for solar, wind, and hydrogen projects, leveraging existing infrastructure to reduce costs.

However, not all firms are adapting swiftly. Coal-dependent utilities and suppliers face mounting financial risks. Stranded coal assets could reach $96.5 billion by 2047, as renewables outpace demand growth. Banks, too, are exposed, with 25–35% of loan books still tied to coal projects. The Reserve Bank of India's potential intervention—mandating coal phase-out plans and green investment incentives—could further pressure laggards.

Investment Opportunities in Renewable Infrastructure

The transition to renewables is creating compelling investment avenues. Solar and wind projects, green hydrogen, and energy storage are attracting capital at unprecedented rates. In Q1 2025, renewable investments in India hit $9.84 billion, a 7.7-fold increase from Q1 2024.

Key players like Adani Green Energy, Renew Power, and Ayana Renewable Power are scaling solar and wind capacity, while firms like Maruti Suzuki and Reliance are diversifying into biogas and hydrogen. The National Green Hydrogen Mission and PLI schemes are further catalyzing growth. Investors should also consider infrastructure enablers, such as grid modernization and EV charging networks, which are critical for integrating renewables.

Risks for Coal-Dependent Firms

Despite the momentum in renewables, coal remains a significant part of India's energy mix. Utilities that fail to pivot risk asset write-downs and regulatory penalties. For example, state-owned DISCOMs face financial strain due to cross-subsidies and rising debt, complicating the shift to renewables. Additionally, global investors are increasingly wary of coal exposure, with ESG funds divesting from high-emission sectors.

The financial risks are not limited to utilities. Banks with large coal portfolios could face balance sheet stress as stranded assets lose value. The RBI's potential mandates for coal phase-out and green finance could accelerate this transition but may also create short-term volatility.

Strategic Recommendations for Investors

1. Prioritize Renewable Infrastructure: Allocate capital to solar, wind, and green hydrogen projects, particularly in states like Gujarat, Tamil Nadu, and Maharashtra, which are leading the transition.
2. Support Energy Transition Playbooks: Invest in firms repurposing coal sites for renewables or developing advanced technologies like small modular reactors (SMRs).
3. Diversify Energy Portfolios: Avoid overexposure to coal-dependent utilities. Instead, target companies with clear decarbonization strategies and government-backed incentives.
4. Monitor Policy and Regulatory Shifts: Track the RBI's green finance initiatives and the National Electricity Plan 2023, which outline the roadmap for phasing out coal.

India's energy transition is not without challenges, but the rewards for investors who align with the shift to renewables are substantial. As the monsoon season boosts hydroelectric output and solar capacity surges, the stage is set for a cleaner, more sustainable energy future. The question for investors is not whether to participate—but how quickly.
