India's renewable energy generation has grown substantially, yet coal remains dominant in its overall energy mix. Identify the structural barriers and suggest a roadmap to bridge this gap.

Q. India's renewable energy generation has grown substantially, yet coal remains dominant in its overall energy mix. Identify the structural barriers and suggest a roadmap to bridge this gap. (15 marks, 250-350 words)

Globally, renewables overtook coal in the electricity mix for the first time in a century in 2025 [1], and India added a record 48.4 GW of renewable capacity, crossing 50% non-fossil installed capacity five years ahead of its NDC deadline [2]. Yet coal still supplies about 55% of the national energy mix and nearly three-fourths of power generation [3] — the persistence is structural, not merely a shortfall of ambition.

Structural barriers - Capacity–generation mismatch: solar's low capacity utilisation means a 50% capacity share translates into a far smaller generation share; coal still carries baseload and evening peaks [3]. - Storage and intermittency deficit: without large-scale batteries and pumped hydro, renewable power cannot be firmed, forcing coal plants to run as backup. - Grid and transmission bottlenecks: renewable-rich states are geographically concentrated, straining inter-state evacuation corridors. - Discom financial distress: state-owned discoms remain loss-making with AT&C losses around 16% [4], weakening their ability to sign new renewable purchase agreements. - Fossil lock-in beyond electricity: transport, steel and cement depend on oil and coking coal; India imports close to 88% of its crude [5], where renewables cannot substitute directly.

Roadmap - Scale battery storage and pumped hydro through viability gap funding, and mandate storage-linked renewable tenders. - Accelerate Green Energy Corridors and inter-state transmission to match generation growth [2]. - Deepen discom reform under the Revamped Distribution Sector Scheme — smart prepaid metering, tariff rationalisation, loss reduction to 12–15% [4]. - Use the National Green Hydrogen Mission to decarbonise hard-to-abate industry, extending the transition beyond the power sector. - Ensure a just transition: reskilling and revenue diversification for coal-bearing districts, so retirement of ageing plants is socially sustainable.

India's renewable achievement is real but confined largely to installed capacity; the harder task is displacing coal in actual generation and in non-electricity energy use. A sequenced push on storage, transmission and distribution finance can convert capacity into dependable clean supply, aligning energy security with the Paris Agreement and SDG-7.
