Adani Energy Solutions Ltd (AESL) has won a transmission project entailing an estimated capital expenditure of Rs 4,700 crore to evacuate renewable energy generated in Karnataka to major load centres in Maharashtra, the company said in a media release submitted to stock exchanges.
AESL, India’s largest private transmission and distribution company and part of the Adani portfolio, said the project would also support the growing pumped storage ecosystem in the Satara, Pune and Mumbai Metropolitan Region (MMR).
The project, titled “Network Expansion Scheme in Western Region to Cater to Pumped Storage Potential near Satara (up to 4,500 MW) – Part A”, was awarded through the Tariff Based Competitive Bidding (TBCB) process, in which AESL emerged as the lowest bidder.
The project will be housed under a special purpose vehicle, Satara Power Transmission Ltd, and is to be delivered within 36 months, according to the release. It will add 562 circuit kilometres (ckm) of transmission lines and 9,000 MVA of transformation capacity to AESL’s network, taking its cumulative transmission capacity to 29,739 ckm and 1,43,425 MVA.
Kandarp Patel, CEO of Adani Energy Solutions Ltd, said pumped storage projects were emerging as a critical enabler of India’s clean energy transition by providing the flexibility and reliability needed to integrate large-scale renewable energy into the grid. He said the Satara project would create a vital transmission backbone supporting both renewable energy evacuation and energy storage deployment, strengthening power flows between southern and western India, and added that AESL remained committed to building future-ready infrastructure that supports the country’s long-term decarbonisation goals.
According to the release, the project includes setting up a 765/400 kV substation at Satara, a Kolhapur-Satara 765 kV double-circuit transmission line, and augmentation of the Kolhapur pooling station along with associated transmission infrastructure.
The company said transmission infrastructure remained the backbone of India’s push to install 500 GW of non-fossil energy capacity by 2030, and that AESL continued to build specialised schemes linking resource-rich renewable energy zones such as solar, wind and pumped storage with major industrial and urban load centres. With this win, AESL’s transmission orderbook now stands at approximately Rs 85,000 crore.AESL serves about 13 million consumers in metropolitan Mumbai and the Mundra Special Economic Zone (SEZ) through its retail electricity distribution business and is also expanding its smart metering operations.
