The Ministry of Power is accelerating renewable energy integration through the development of Green Energy Corridors (GEC) and expansion of the Inter-State Transmission System (ISTS), aimed at supporting India’s growing clean energy capacity.
According to the government, the transmission infrastructure expansion is planned to integrate over 500 GW of non-fossil fuel capacity by 2030 and more than 600 GW by 2032, including projects under GEC-I and GEC-II.
Under the National Electricity Plan (NEP) Volume II – Transmission, the country’s transmission network of 220 kV and above is expected to expand to 6.48 lakh circuit kilometres, while transformation capacity is projected to reach 2,345 GVA by 2031–32. In addition, inter-regional transmission capacity is planned to increase from 120 GW as of January 2026 to 168 GW by 2032.
Transmission schemes linked to renewable energy generation projects are currently under various stages of phased implementation, aligned with the pace of renewable capacity additions.
The Ministry of New and Renewable Energy (MNRE) is implementing the Green Energy Corridor (GEC) intra-state transmission scheme across ten states — Rajasthan, Karnataka, Andhra Pradesh, Himachal Pradesh, Madhya Pradesh, Kerala, Gujarat, Uttar Pradesh, Maharashtra, and Tamil Nadu — in two phases, GEC-I and GEC-II, to facilitate evacuation of 44 GW of renewable energy capacity. So far, 26 GW has already been integrated, while GEC-III, aimed at large-scale renewable integration, is currently under consideration.
To address intermittency challenges associated with renewable energy sources, the government is promoting a combination of energy storage and hybrid solutions to maintain grid stability and ensure reliable power supply.
Under the NEP transmission plan, infrastructure has been mapped for 35.6 GW of Pumped Storage Projects (PSPs) by 2031–32, with plans to scale up transmission readiness for 100 GW of PSP capacity between 2025–26 and 2035–36. Additionally, 47 GW of Battery Energy Storage Systems (BESS) has been considered for grid integration by 2031–32.
To support energy storage deployment, the government has introduced two Viability Gap Funding (VGF) schemes for approximately 43.8 GWh of BESS capacity, launched in March 2024 and June 2025.
Meanwhile, the Ministry of Heavy Industries is implementing the National Programme on Advanced Chemistry Cell (ACC) Battery Storage with a ₹18,100 crore Production Linked Incentive (PLI) scheme to establish 50 GWh of ACC battery manufacturing capacity, including 10 GWh for grid-scale storage applications.
Further regulatory reforms have been introduced by the Central Electricity Regulatory Commission through the Connectivity and General Network Access to the Inter-State Transmission System (Third Amendment) Regulations, 2025. These regulations introduce solar-hour and non-solar-hour connectivity, enabling optimal utilization of transmission infrastructure and promoting hybrid renewable energy projects combining solar, wind, and battery storage.
In parallel, the government is supporting distributed renewable energy adoption through the PM Surya Ghar: Muft Bijli Yojana, launched in February 2024 by MNRE. The scheme aims to install rooftop solar systems in one crore households by FY 2026–27, with a total outlay of ₹75,021 crore.
The scheme simplifies rooftop solar adoption through an online national portal, enabling end-to-end application processing and direct subsidy disbursement to consumer bank accounts. It also provides collateral-free loans from nationalized banks with a tenure of up to 10 years, supported through integration with the JanSamarth portal. Regulatory processes have also been simplified, including waiver of technical feasibility requirements and automatic load enhancement up to 10 kW.
As of February 2026, 31.04 lakh households have installed rooftop solar systems under the programme.
Overall, the development of Green Energy Corridors and the expansion of the national transmission network are expected to provide the backbone for large-scale renewable energy integration. At the same time, the promotion of battery storage, pumped storage, and hybrid renewable projects is enhancing grid flexibility and enabling reliable supply of firm green power at competitive prices.
As of January 2026, India’s installed renewable energy capacity stands at around 263 GW. Transmission infrastructure is currently being implemented to integrate approximately 207 GW of upcoming wind and solar capacity, while 18 GW of renewable capacity is planned for integration through intra-state networks under the GEC scheme. In addition, about 19 GW of new hydropower capacity is expected to be added by 2030.
The information was shared by Shripad Yesso Naik, Minister of State in the Ministry of Power, in a written reply in the Rajya Sabha.
