In a massive infrastructure milestone advancing India's clean energy transition and power grid modernization on October 24, 2026, the Union Cabinet officially approved the Green Energy Corridor Phase-III (GEC-III) scheme with an unprecedented financial outlay of ₹1,86,405 crore. The flagship central infrastructure initiative aims to facilitate the evacuation and grid integration of up to 135 gigawatts (GW) of renewable energy capacity into national power systems by the 2032–33 financial year. Designed to transform regional electricity distribution networks, the initiative allocates over ₹1.36 lakh crore toward developing high-capacity intra-state transmission systems (InSTS) across key renewable-rich states including Gujarat, Rajasthan, Tamil Nadu, Andhra Pradesh, and Karnataka. To tackle intermittency challenges inherent in large-scale solar and wind power generation, the approved framework includes a dedicated ₹50,000 crore sub-component specifically earmarked for deploying 50 gigawatt-hours (GWh) of utility-scale Battery Energy Storage Systems (BESS). Power sector analysts and environmental economists highlighted that the rollout of GEC-III forms the vital backbone for India’s long-term target of achieving 500 GW of non-fossil fuel capacity, ensuring that surplus green electricity generated in high-resource western and southern corridors is seamlessly transmitted to heavy industrial and urban demand centers nationwide while reinforcing grid reliability, lowering carbon emissions, and driving extensive domestic capital investment across green infrastructure engineering ecosystems.
Cabinet Clears Landmark Transmission Plan for 500 GW Clean Energy Goal
In a major initiative to modernize India's power transmission infrastructure and integrate non-fossil power into the national grid, the Union Cabinet approved Phase-III of the Green Energy Corridor (GEC-III) scheme with a total financial outlay of ₹1.86 lakh crore.
The approval represents the single largest transmission infrastructure package ever cleared by the Union Government. It addresses the evacuation bottleneck that has emerged as massive solar and hybrid utility parks come online in resource-dense corridors across the country. GEC-III focuses directly on bridging large-scale renewable generation hubs in western and southern regions with major consumption centers across northern and eastern industrial zones.

Bridging Resource-Rich Deserts with Industrial Load Centers
The technical framework of Phase-III builds upon the transmission foundations laid by GEC-I (concentrated on intrastate grids) and GEC-II (focused on interstate transmission lines).
Unlike earlier phases that handled scattered smaller plants, GEC-III is calibrated for ultra-mega scale developments:
High-Voltage Direct Current (HVDC) Corridors: Multi-terminal, multi-gigawatt HVDC links designed to transport bulk power over long distances with minimal transmission losses.
Desert & Offshore Evacuation: Dedicated high-capacity substations engineered to connect the vast Khavda Renewable Energy Park in Gujarat, solar-wind hybrid parks in western Rajasthan, and emerging offshore wind test projects off the coasts of Tamil Nadu and Gujarat.
Grid Balancing & Battery Energy Storage (BESS): Advanced dynamic reactive power compensation devices and grid-scale BESS integration to mitigate the intermittency of solar and wind generation.
The Central Government will extend Central Financial Assistance (CFA) covering a significant portion of intrastate infrastructure costs to ensure State Transmission Utilities (STUs) can expand their local feeder lines without straining debt profiles.
"To reach 500 GW of non-fossil capacity by 2030, generation capacity alone is insufficient without matching evacuation readiness. Green Energy Corridor Phase-III ensures that zero-carbon power produced in renewable-rich desert regions reaches industrial manufacturing centers reliably, cementing India’s grid resilience and clean energy transition." — Ministry of Power Official Statement
Economic Impact, Domestic Manufacturing, and Job Creation
Beyond energy transition targets, GEC-III provides a long-term capital boost to India's heavy electrical manufacturing sector.
Under the scheme's statutory guidelines, procurement of transformers, conductors, high-tension switchgears, and transmission towers must comply with domestic value-addition and Public Procurement (Preference to Make in India) mandates. The investment is projected to generate over 1.2 lakh direct and indirect jobs across engineering, procurement, construction (EPC), and maintenance services over the five-year rollout timeline.
