Adani Electricity Mumbai Ltd (AEML) has received a AAA credit rating from India Ratings, becoming the first privately owned power distribution company in India to achieve a rating equivalent to the sovereign. The upgrade underscores strong regulatory backing, improving financial fundamentals, and a sustained deleveraging profile under a stable cost-plus regulatory framework.
India Ratings said the rating reflects consistent regulatory support, steady cash flows, and enhanced credit metrics. The agency highlighted timely and cost-reflective tariff orders issued by the Maharashtra Electricity Regulatory Commission (MERC), which have enabled full recovery of past regulatory assets, including carrying costs. As a result, regulatory balances have moved into a surplus position in the first half of FY26.
The Mumbai utility, acquired by the Adani Group in 2018 from the Anil Dhirubhai Ambani Group, has undergone a significant turnaround. Since the acquisition, AEML has more than doubled its asset base to over ₹10,000 crore, driven by sustained capital expenditure to cater to rising electricity demand in the country’s financial capital.
Despite higher investments, consumer tariffs have largely remained stable. India Ratings attributed this to prudent financial management and the Adani Group’s integrated power model, which provides access to low-cost generation within the conglomerate and helps cushion input cost volatility.
The agency also pointed to AEML’s strengthening balance sheet and expanding regulated asset base (RAB). The RAB is expected to exceed ₹100 billion by the end of FY26, while gross adjusted debt-to-RAB is projected to decline below 1.0 times, supported by strong internal accruals and disciplined capital allocation.
Operational performance has improved alongside financial metrics. Distribution losses fell to 4.3 per cent in the first half of FY26, and collection efficiency remains around 99 per cent. India Ratings further noted that the utility’s entire long-term foreign currency debt is fully hedged, resulting in comfortable liquidity and low refinancing risk.
On the sustainability front, Adani Electricity Mumbai has significantly increased its renewable energy procurement. Renewables now account for about 40 per cent of total power sourced, up from less than 3 per cent in 2019. The company plans to raise this share to 60 per cent by 2027, a move that could position Mumbai as the first major global city with such a high proportion of green power in its electricity mix.
Most of the renewable supply is expected to come from Adani Green Energy Ltd, while thermal requirements will be met by Adani Power Ltd, both of which are among the lowest-cost producers in their respective segments.
