Adani Green Energy operates as a pure-play renewable power generator, developing, owning, and operating solar, wind, hybrid, and battery energy storage assets. The company sells electricity primarily through long-term power purchase agreements, sitting at the top of the power value chain as a capital-intensive producer. It holds a dominant scale position in India, surpassing 20 GW of greenfield capacity in mid-2026 and operating the world's largest single-location renewable installation at Khavda with over 10 GW. The economics of this business are exceptional, evidenced by a 94% EBITDA margin from power supply in the first quarter of fiscal 2027. This margin level reveals a structurally protected utility model where capital costs are recovered through fixed tariffs, leaving the residual cash flows highly insulated from input cost volatility.
The durability of these economics stems from specific, underappreciated barriers rather than commodity scale alone. The primary moat is the sheer replication time required to secure land, transmission rights, and equipment for double-digit gigawatt projects. While renewable generation is commoditized, Adani Green has integrated backward into a group-manufactured 5.2 MW wind turbine supply and executes module installations at 400 to 500 MW per month, mitigating supply risk. More critically, the company has structurally de-risked its offtake by contracting approximately 4 GW of generation capacity to Adani Energy Solutions on a 25-year fixed basis for solar and wind, and 15-year contracts for batteries. This internal transfer mechanism eliminates market vagaries for its merchant and infirm power, converting a historically volatile revenue stream into a predictable, investment-grade utility cash flow.
The inflection point driving the next 18 to 24 months is the resolution of transmission bottlenecks and the commercialization of battery storage. By the end of fiscal 2027, the company will commission over 10 GWh of battery energy storage systems at a capital cost of INR 1.5 crore per MWh, generating INR 25 to 30 lakh of EBITDA per MWh through peak pricing arbitrage. Concurrently, an additional 7 GW of evacuation capacity is expected by the end of calendar 2026, with the balance of 14 GW coming online shortly after. This transmission rollout will allow the conversion of 5.3 GW of infirm power into long-term PPAs by December 2026, eliminating the INR 1,300 to 1,500 crore annual EBITDA loss currently suffered from curtailment and merchant exposure. By fiscal 2028, the business will approach a run-rate EBITDA of INR 21,000 crore, driven entirely by these newly contracted assets and zero curtailment at Khavda.
Management's walk-talk shows a mixed but improving trajectory on capacity execution. They repeatedly guided 5 GW of new capacity for fiscal 2026 but delivered only 3.3 GW, a 34% shortfall blamed on extended monsoons and regulatory delays. However, operational targets like the Khavda capacity utilization factor of 32% were met exactly, and financial metrics tracked closely with guidance. For fiscal 2027, they have guided 4.5 to 5 GW of renewable additions and INR 42,000 crore in capex, with Q1 capex already surging 41% year-on-year to INR 8,800 crore. The balance sheet is leveraged for this growth, with operating debt to run-rate EBITDA at 4.6x and overall debt at 5.6x, but management expects this to remain stable before deleveraging sharply from fiscal 2029 as capex completes.
The quantified earnings path requires two specific conditions to hold: the timely completion of 14 to 15 GW of transmission lines by early fiscal 2028, and the successful stabilization of 10 GWh of battery storage without major operational disruptions. The single most important watchpoint is the execution of the external grid infrastructure. If the promised 7 GW of evacuation capacity by December 2026 slips due to Right of Way challenges or stringing delays, the company will be unable to convert its infirm power to PPAs, trapping capital in low-yielding merchant sales and invalidating the run-rate EBITDA target. The tension between high gross margins and delayed capacity additions is purely operational, tied entirely to transmission line completion.
