Quick Revision: The Green Energy Corridor Phase-III scheme institutionalises Battery Energy Storage Systems (BESS) within intra-state transmission networks to enhance grid flexibility, support renewable energy integration, and ensure reliable power supply during peak demand.

Why is this in the news?

The Union Cabinet’s approval of the Green Energy Corridor Phase-III scheme marks a decisive institutional step toward integrating large-scale battery energy storage systems (BESS) into India’s intra-state transmission networks. This initiative directly advances the country’s renewable energy capacity addition targets by addressing the critical constraint of grid flexibility and energy dispatchability, thereby ensuring reliable integration of intermittent solar and wind power into the grid at the sub-national level.

Background

• India’s Nationally Determined Contributions (NDCs) under the Paris Agreement commit to achieving 50% cumulative electric power installed capacity from non-fossil fuel-based energy resources by 2030, with a target of 500 GW of renewable energy capacity by 2030.
• The Green Energy Corridor (GEC) initiative was first conceptualised under the National Mission on Power Sector Development in 2015 to facilitate the evacuation of large-scale renewable energy from solar and wind-rich states to load centres across India.
• Phase-I (2015–2020) focused on inter-state transmission corridors to connect renewable energy zones to the national grid, while Phase-II (2020–2025) expanded to include intra-state transmission systems in high renewable-potential states such as Gujarat, Rajasthan, Karnataka, and Tamil Nadu.
• Grid integration challenges have intensified with the rapid growth of variable renewable energy (VRE), necessitating storage solutions to manage diurnal and seasonal imbalances between generation and demand.
• The Union Budget 2023–24 allocated ₹3,000 crore for the viability gap funding (VGF) of battery energy storage projects, signalling a policy shift toward incentivising storage infrastructure at scale.

What is the Green Energy Corridor Phase-III scheme?

• The Green Energy Corridor Phase-III scheme is a centrally sponsored initiative aimed at developing intra-state transmission systems equipped with Battery Energy Storage Systems (BESS) to facilitate the seamless integration of renewable energy into state grids.
• The scheme is implemented by the Ministry of Power in collaboration with state transmission utilities (STUs) and the Power Grid Corporation of India Limited (PGCIL), ensuring alignment with the National Transmission System (NTS) and state-level renewable energy policies.
• BESS integration under this scheme will enable time-shifted energy dispatch, grid stabilisation during peak demand, and ancillary services such as frequency regulation and voltage support, thereby enhancing the reliability of renewable-rich states.
• The scheme is designed to address the technical and financial viability of storage deployment by providing central financial assistance (CFA) for capital expenditure (capex) and viability gap funding (VGF) for public-private partnerships (PPP) in storage projects.
• It complements the existing Green Energy Corridor infrastructure by expanding the scope from inter-state to intra-state transmission, ensuring that renewable energy generated within a state can be utilised locally without congestion in the national grid.
• The implementation framework includes detailed project reports (DPRs), techno-economic feasibility studies, and environmental and social impact assessments (ESIA) to ensure sustainable and inclusive development.
• The scheme is expected to catalyse investment in storage manufacturing, grid modernisation, and ancillary services, thereby creating employment opportunities in the renewable energy and power sector ecosystem.
