Read Original ArticleKey Points
The Union Cabinet's approval of the Green Energy Corridor Phase-III marks a significant step towards renewable energy integration in India. This initiative is crucial for UPSC aspirants, particularly for GS Paper 3, focusing on infrastructure and energy security. Last Updated: 01-10-2026
Key Facts About Green Energy Corridor Phase-III
- The Green Energy Corridor (GEC) is a national infrastructure initiative by the Ministry of New and Renewable Energy (MNRE).
- Launched in 2015 following a 2012 PGCIL study, it aims to integrate renewable energy with conventional power grids.
- Phase-III focuses on evacuating up to 135 GW of renewable energy across states and union territories.
- It includes 50 GWh of Battery Energy Storage Systems (BESS) to manage intermittency and congestion.
- Implemented through Tariff Based Competitive Bidding (TBCB) and Cost Plus Basis (CPB) methodologies.
- State Transmission Utilities (STUs) act as the nodal agencies for execution.
- Full commissioning is targeted by FY 2032–33.
- Aligns with India's goal of 900 GW non-fossil fuel capacity by 2035.
India's Renewable Energy Integration
The Green Energy Corridor is pivotal for India's strategic goal of enhancing energy security and reducing carbon emissions. By integrating renewable energy into the national grid, India aims to meet its international climate commitments and boost its global standing. The initiative supports economic growth by creating jobs and fostering technological advancements in the energy sector.
UPSC Relevance
- GS Paper 3: Infrastructure, Energy Security, Environmental Conservation.
- Prelims Angle: Questions on GEC's objectives, key features, and phases.

Frequently Asked Questions (FAQs)
- What is the Green Energy Corridor? The Green Energy Corridor (GEC) is a transmission infrastructure initiative aimed at integrating and evacuating large-scale renewable energy while maintaining grid stability.
- What is the key objective of GEC-III? GEC-III aims to strengthen the Intra-State Transmission System and facilitate evacuation of up to 135 GW of renewable energy by FY 2032–33.
- What is the role of BESS under GEC-III? GEC-III incorporates 50 GWh of Battery Energy Storage Systems to manage renewable intermittency, reduce congestion, and support power availability during non-solar hours.
- How does GEC improve grid stability? It uses Renewable Energy Management Centres, forecasting systems, reactive power compensation, and energy storage to manage fluctuations in solar and wind generation.
- How will GEC-III be implemented? State Transmission Utilities (STUs) are the principal implementing agencies. Greenfield projects will use Tariff Based Competitive Bidding, while brownfield strengthening will follow a Cost Plus Basis.
