Adani Energy Solutions Ltd. (AESL) has won a major transmission project in Maharashtra with an estimated capital expenditure of around ₹4,700 crore, aimed at strengthening the evacuation of renewable energy generated in Karnataka and supporting the rapidly expanding pumped storage ecosystem across Satara, Pune and the Mumbai Metropolitan Region (MMR).
The project, formally titled “Network Expansion Scheme in Western Region to Cater to Pumped Storage Potential near Satara (up to 4500 MW) – Part A,” was awarded through the Tariff Based Competitive Bidding (TBCB) process, with AESL emerging as the lowest bidder. The project will be housed under the special purpose vehicle Satara Power Transmission Ltd.
AESL is expected to complete the project within 36 months. Once commissioned, it will add approximately 562 circuit kilometres of transmission lines and 9,000 MVA of transformation capacity to the company’s portfolio.
The project will include the development of a 765/400 kV substation at Satara, a Kolhapur–Satara 765 kV double-circuit transmission line, augmentation of the Kolhapur pooling station, and other associated transmission infrastructure.
With this project, AESL’s cumulative transmission network will increase to approximately 29,739 circuit kilometres, while its transformation capacity will rise to around 1,43,425 MVA.
The project is particularly significant as India expands its renewable energy and energy-storage capacity. Renewable sources such as solar and wind are inherently variable, making large-scale storage increasingly important for maintaining reliable electricity supply. Pumped storage projects can store electricity when generation is high and release it when demand rises, helping balance the grid and integrate larger volumes of renewable power.
According to Kandarp Patel, CEO of Adani Energy Solutions, the Satara transmission project will create an important transmission backbone for both renewable energy evacuation and energy-storage deployment. He highlighted the role of pumped storage in providing flexibility and reliability as India moves towards a larger clean-energy system.
The transmission infrastructure will also strengthen power flows between southern and western India, connecting renewable-energy generation and storage resources with major industrial and urban demand centres.
The project comes as India works towards its target of 500 GW of non-fossil energy capacity by 2030. As renewable generation expands, transmission networks capable of moving electricity from resource-rich regions to major consumption centres are becoming increasingly critical.
AESL said it continues to focus on specialised transmission projects designed to connect renewable-energy hubs—including solar, wind and pumped storage—with large load centres across the country.
The latest win further strengthens AESL’s position in India’s private transmission sector and highlights the growing importance of grid infrastructure alongside renewable generation and energy-storage investments in the country’s clean-energy transition.
