Budgeting for Net Zero: Powering India's reliable clean energy future
An assessment of firm and dispatchable renewable energy (FDRE) competitiveness to 2050
India needs clean, reliable, affordable power. This study assesses the cost competitiveness of firm and dispatchable renewable energy (FDRE)—solar, wind, and storage systems delivering 24-7 clean energy. FDRE is fast to build, can compete with coal, creates net jobs, and cuts emissions, but could be costlier than standalone solar, wind, or storage and should be used where demand profiles require firmness.
Key Messages
-
Ensuring 24-7 power from FDRE requires developers to oversize the amount of solar and wind, resulting in surplus power generation. Selling 50% of surplus makes FDRE cheaper than new coal by 2030, selling 30% delays parity to 2048, and selling 100% (optimistic scenario) makes FDRE already cheaper.
-
Including mortality, morbidity, and carbon costs raises coal's price from INR 4.65/kWh to INR 13.19/kWh, making FDRE competitive in all scenarios. This shows the need for current power procurement frameworks to reflect pollution and climate costs in pricing.
-
FDRE raises GDP by 0.5% in 2032, 1% by 2038, and 1.8% by 2050 on an annual basis and creates 64,000 net jobs by 2050 (after accounting for coal job losses), compared to our baseline scenario (no FDRE). Gains come from lower air pollution, higher productivity, and investment in clean energy.
-
Coal-based power plants take 5–7 years to commission, while FDRE projects can be built in 2–2.5 years, even with storage included. Long lead times for coal increase cost uncertainty, fuel supply risks, fixed capacity charges, and expose discoms to stranded-asset risks as renewables become cheaper.
India's electricity system is evolving rapidly in response to rising demand, a changing resource mix, and the need for round-the-clock clean power. While coal remains the dominant source of reliable electricity, the declining costs of solar, wind, and battery storage are opening realistic alternatives. FDRE projects deliver clean power in line with specific demand profiles, shifting India from generation-based procurement to demand-based renewable solutions. However, uptake has been slow and questions remain around cost competitiveness, revenue certainty, and investment risk for developers and distribution companies.
This study evaluates three core questions: whether FDRE can match or undercut new thermal power on cost; what kind of government support (if any) would be required to close any cost gap; and how FDRE deployment affects economic growth, employment, air pollution, and climate outcomes. Using scenario modelling, externality assessments, and stakeholder consultations, we compare FDRE cost trajectories with new pithead coal plants, estimate cost gaps to 2050, and explore the broader economic benefits of scaling FDRE.
Our findings suggest that FDRE can provide reliable clean power at competitive prices, but that market design and tender structure will determine the pace and scale of deployment. The recommendations focus on practical changes that improve developer certainty, reveal true resource costs, and align energy procurement with long-term national priorities.
