Adani Green Energy is an operating-leverage story built on a 20.8 GW renewable fleet and a rapidly scaling battery business. The company sells most output under long-term contracts, with AESL taking the C&I and battery offtake, and operates the Khavda park where 10.8 GW is already commissioned. The reported economics are strong: H1 FY27 revenue from power supply rose 36% to ₹8,299 crore, EBITDA rose 41% to ₹7,957 crore and margin was 93%; Q2 revenue rose 45% to ₹4,000.19 crore and EBITDA 51% to ₹3,835 crore. Total H1 EBITDA was ₹8,276 crore, and management said it would have been close to ₹9,000 crore without curtailment. Those are reported results, not annualised guidance.
The business economics are protected by long contracts and a low marginal cost of renewable generation. Management states a 13-14% ROA threshold on capacity tied to AA+ counterparties, with 25-year solar and wind contracts and 15-year battery contracts. About 72% of project loans are fixed for 3-5 years, and overall interest cost is 8.9%, down from 11.1% in 2019. AG23L, about 15% of EBITDA, became AAA at an 8.5% rate. The 13-14% ROA is a management target, not a reported outcome; it translates to a higher ROE because the model runs on roughly 75:25 leverage. The analyst inference is that the equity return is sensitive less to the nominal tariff than to commissioning delays and uncontracted capacity.
The near-term earnings path has three operating variables. First, FY27 renewable commissioning: the original target is 4.5-5 GW, but management now says Phase 3 evacuation is expected in Q4 FY27 and the second 7 GW line is further delayed. Balance-of-system is ready, so the constraint is the external corridor. Second, BESS: installed capacity reached 6.6 GWh after 3 GWh was added in Q2 FY27, more than half of India's operational base, and management expects to exceed 10 GWh in FY27. Third, contracting: only 3.5 GWh of the 6.6 GWh is tied to AESL, with 3.1 GWh in process. AESL pays for scheduled power if a procurer or the grid backs down, but unscheduled generation is not paid. That distinction matters for the merchant-to-C&I de-risking thesis.
The FY27 run-rate EBITDA target of ₹21,000 crore, up from about ₹17,000 crore, was given in Q1 FY27. Q2 did not update it; H1 total EBITDA of ₹8,276 crore leaves the target open. The reported margin and volume growth show operating leverage, but the conversion to full-year run-rate EBITDA depends on commissioning and curtailment. Management's FY30 programme is ₹2.4 lakh crore of capex through FY30, and it describes 45 GW renewable, 5 GW pumped storage and 40-50 GWh of batteries by 2029-30. Leverage is 5.6x; management expects 4.5-5x until FY28-29 and below 4x after FY29-30 as capex completes. That is guidance, not a reported deleveraging.
Capital allocation is the second leg of the thesis. Khavda has 10.8 GW commissioned, and the site supports co-located batteries that use otherwise curtailed power. Chitravathi, the maiden 500 MW pumped storage project, is progressing toward completion by year-end but remains uncontracted. The AESL contracts are 25 years for solar and wind and 15 years for batteries, with Q2 citing AESL solar at ₹2.70 per unit and wind at ₹3.93 per unit, against merchant solar at ₹2.4 versus about ₹2.1 last year. These contracts reduce merchant volatility, but they also cap upside and concentrate counterparty exposure in a related listed entity. The 13-14% ROA threshold is the test of whether the transfer price is adequate.
Management delivery is mixed. The FY26 capacity target was delivered at 5.1 GW, and BESS scaled from a late 3.5 GWh first tranche to 6.6 GWh. But the Khavda evacuation promise slipped repeatedly, from 4 GW by June 2025 and 7 GW by December 2025 to Phase 3 in Q4 FY27. That history argues for treating the FY27 4.5-5 GW target as conditional rather than assured. The BESS target has more company control, but 3.1 GWh of contracting is still open. Chitravathi has moved from calendar 2026 to year-end, with no offtake disclosed.
The falsifiers are specific. A Phase 3 slip beyond Q4 FY27 would leave the 4.5-5 GW renewable target and the 5.3 GW infirm-to-PPA conversion exposed. A failure to exceed 10 GWh of BESS, or a failure to contract the remaining 3.1 GWh on acceptable AESL terms, would weaken the storage thesis. Chitravathi not commissioning by year-end, or commissioning without a contract, would add uncontracted peak-risk capacity. Leverage failing to fall toward 4.5-5x by FY28-29 would show that capex is outrunning EBITDA. Conversely, delivery of Phase 3, 10+ GWh of BESS and the AESL contracts at the stated 13-14% ROA would validate the operating-leverage case without requiring a higher tariff. No price target or valuation judgment is implied.
