India’s first geothermal milestone is real — but its weight on ONGC’s balance sheet is a separate question.
The ONGC geothermal project in Ladakh’s Puga valley has cleared a procedural hurdle, not an earnings one. Lieutenant Governor Vinai Kumar Saxena has approved a five-year extension of the tripartite memorandum of understanding with Oil and Natural Gas Corporation, keeping India’s first geothermal power effort alive.

For shareholders, the development is symbolically large and financially small — a distinction worth holding on to as headlines play up the “India’s first” framing.
What the ONGC geothermal project actually involves
The original agreement, signed in February 2021, lapsed in February 2026 before fieldwork was finished, with harsh high-altitude terrain repeatedly slowing progress. The scope is a one-megawatt pilot plant plus a detailed report for possible large-scale use. ONGC has so far drilled a single well to 405 metres, described in the official Ladakh administration release as its deepest in the region; the five-year window simply buys time to finish scientific exploration that weather kept interrupting.

Why the investor angle is scale, not steam
Set one megawatt against ONGC’s stated ambition of roughly 10 GW of renewables by 2030, and the pilot barely registers on capacity or profit. The company has separately approved a ₹4,963 crore, 0.6 GW solar-and-wind project targeted for 2028, with around ₹5,000 crore earmarked for renewables capex. ONGC also runs a 50:50 renewables joint venture with NTPC Green Energy, a vehicle far more relevant to its clean-power scale than the Ladakh pilot. (Source: TipRanks / ONGC earnings call)
Treated honestly, the ONGC geothermal project is a multi-year science programme, not a 2026 revenue driver.
Where the stock and the calendar stand
ONGC traded near ₹296–₹305 around 21 May 2026, close to its 52-week high, on a price-earnings ratio of about 12 and a dividend yield above 4%. The board meets on 26 May 2026 to approve FY26 audited results and consider a final dividend — a more direct near-term event for the stock than a remote pilot in Ladakh. Crude prices and gas realisations, not geothermal, remain the dominant swing factors for ONGC’s quarterly numbers. (Source: Tickertape / Screener)
What to verify before drawing conclusions
- ONGC’s FY26 results and the renewables capex line at the 26 May board meeting, for the real scale of green-energy spending.
- Whether the geothermal pilot carries any disclosed standalone cost or output in company filings, which would likely be immaterial.
- Progress against the 10 GW-by-2030 target, which moves the transition story far more than a one-megawatt well.
