Nearly 75 Percent of Energy Professionals Expect Renewables to Surpass Coal by 2035: ENCIS Survey

India has crossed the first great threshold of its electricity transition: non-fossil sources now constitute more than half of installed capacity. The harder threshold, producing more electricity from renewables than from coal, reliably and across every hour, remains ahead. A new survey by The Energy and Climate Initiatives Society (ENCIS) finds that nearly 75 percent of the 250 professionals surveyed across Delhi NCR, Mumbai, Pune, Bangalore and Chennai

expect renewables to surpass coal as India’s primary source of electricity by 2035. Significantly, 28 percent anticipate the crossover by 2030, signalling confidence that the transition could advance faster than current planning assumptions.

The findings will inform deliberations at Bharat Electricity, POWERGEN India and Indian Utility Week 2026, from September 01-03, 2026 at Yashobhoomi, IICC, New Delhi. The event will unite over 15,000 energy professionals, 250 plus exhibitors, and 150 plus industry leaders on a single, integrated platform. Featuring a high-level summit, exhibition and awards programme, the event will showcase India’s clean energy transition, spotlight innovations in smart energy and connect attendees with key buyers and thought leaders from India and the ASEAN region. These landmark events will set new benchmarks for sustainability and innovation, shaping the next phase of India’s energy leadership.

Bhupinder Singh Bhalla, IAS (Retd.), Honorary Chairman, Bharat Electricity Council, and Former Secretary, Ministry of New and Renewable Energy, Government of India, said, “Renewables are already the dominant destination for new investment. The defining question is whether India can convert variable capacity into dependable, affordable electricity when required. That demands storage, transmission, flexible generation, responsive demand and sophisticated markets operating as one system. The transition will be won not by megawatts alone, but by the firmness and intelligence of every megawatt-hour delivered.”

As of July  31, 2026, India had 291.7 GW of renewable capacity and 300.5 GW of total non-fossil capacity. Yet during FY2025-26, thermal sources generated approximately 1,307 billion units, against about 478 billion units from large hydro and other renewables combined. India has transformed its capacity base; its operating power system remains substantially thermal-dependent.

P. K. Pujari, IAS (Retd.), Honorary Chairman, ENCIS; Former Secretary, Ministry of Power; and Former Chairperson, Central Electricity Regulatory Commission, said, “This must not become a binary contest between coal and renewables. Coal’s role will evolve before it declines, from the default source of energy towards a flexible provider of adequacy and strategic reliability. Renewables will become predominant only when the system can absorb, store, move and dispatch them without transferring unacceptable cost or risk to consumers.”

The industry is signaling a clear preference for solar energy, with 61 percent of respondents selecting it as the decisive growth choice. Wind energy follows, chosen by 14 percent of respondents, while green hydrogen and hydro/biomass are selected by 11 percent and approximately 12 percent, respectively. The main drivers of this transition are climate and Net Zero commitments, cited by 32 percent of participants, along with falling renewable costs, which account for 27 percent. However, significant barriers remain: grid integration and reliability are identified as the largest challenge by 29 percent of respondents, followed by financing gaps at 24 percent, and issues with land acquisition and permitting at 18 percent.

The survey presents an acceleration scenario, not a settled forecast. By 2035-36, the Central Electricity Authority projects 1,121 GW of capacity, with non-fossil sources at 70 percent. Still, coal will provide nearly half of electricity, while renewables contribute about 43 percent. This gap between industry ambition and planning highlights both opportunity and challenge. ENCIS calls for measuring reliable delivery, not just capacity, proactive grid investments, market reforms and upgrading thermal assets. The real test for India is no longer building renewables competitively, but creating the systems needed for dependable, large-scale clean power.
