Adani Green Energy misses its curtailment resolution timeline
Management had said prior-year EBITDA losses would not recur. Three months later, curtailment still impacts EBITDA by 5-7%, with relief now pushed to end of calendar year.
What's new
- AGEL crossed 20 GW of installed renewable capacity, India's largest greenfield addition.
- Q1 power-supply revenue ₹4,280 cr, up 29% YoY; EBITDA ₹4,122 cr, up 33%, margin 94%.
- Battery storage reached 3.5 GWh installed; separate reporting planned for tracking.
- ~4 GW of former merchant capacity moved to arm's-length C&I contracts with AESL, removing market-fluctuation risk.
Themes from the call
De-risking
Merchant capacity shifted to long-term fixed-price C&I contracts with AESL, removing spot-price exposure and aligning returns with hurdle IRR of 15-16%.
Curtailment
EBITDA continues to face 5-7% impact from grid constraints at Khavda; resolution expected by end of calendar year after 7 GW of evacuation capacity comes online.
Storage
Battery storage commissioned 3.5 GWh; management expects EBITDA contribution of ₹25-30 lakhs per MWh over the next nine months.
Guidance watch
- FY27 greenfield renewable capacity addition target: 5 GW (excluding BESS and pumped storage).
- BESS target: 10+ GWh by FY27, ~50 GWh by FY30.
- FY27-end operational EBITDA run-rate expected to reach ~₹21,000 cr from current ~₹17,000 cr.
- FY27 CapEx guidance: ~₹42,000 cr.
Risk flags
- Khavda curtailment remains unquantified in absolute terms; resolution timeline pushed to end of calendar year.
- BESS contribution requires successful capitalization and stabilization; quarterly phasing not provided.
- Pumped hydro projects (ex-Chitravathi) remain about two years away with no offtake decisions.
Key quotes
-
"We have taken off the risk of merchant capacities and the risk of market fluctuations."
— Ashish Khanna, management -
"Curtailment has an impact in the range of 5-7% on our EBITDA as we speak. Gradually, as and when more transmission lines come up, we do foresee these tendencies of curtailment phasing out."
— Management, July 2026 call
The brief
Adani Green Energy crossed 20 GW of installed renewable capacity this quarter, a milestone the company described as the fastest greenfield build in India. The numbers support the story: power-supply revenue rose 29% to ₹4,280 cr, EBITDA hit a 94% margin, and energy sales grew 30% to 13.7 billion units. But the one number that did not change is curtailment. Three months ago management told investors that prior-year EBITDA losses from grid constraints at Khavda — an estimated ₹1,300-1,500 cr — would not recur. This quarter curtailment still shaved 5-7% off EBITDA, and relief was pushed to the end of the calendar year. The inconsistency is not a blowup. The business is executing well. The 4 GW of former merchant capacity moved to long-term C&I contracts with AESL removes a major risk, and the battery storage rollout is visible: 3.5 GWh now installed, with separate reporting to follow. But the curtailment miss means management's timeline guidance is not yet reliable. The stock is pricing in a smooth transmission buildout. Any further delay would stress the narrative.
Adani Green is executing on the ground but missing on its own timeline. The curtailment flip makes its guidance a lagging, not leading, indicator.
