How to structure your answer
Introduction: Define the Green Energy Corridor as a dedicated transmission network for renewable power.
Body: (1) Why it is needed — variability and grid-stress of clean power; (2) what it builds — intra-state and inter-state lines, substations, control centres; (3) how it eases conventional-energy problems — cuts coal dependence, emissions and import bills.
Conclusion: Position it as the backbone of the non-fossil transition.

Introduction: The Green Energy Corridor (GEC) is a dedicated transmission network, steered by the Ministry of New and Renewable Energy, built to carry power from large solar and wind zones into the national grid.
Why it is needed: Renewable output is variable and clustered in a few resource-rich states, while the older grid was designed around steady coal and hydro plants. Without firm evacuation lines, clean power gets curtailed and stranded.
What it builds: Intra-state and inter-state high-voltage lines, new substations and Renewable Energy Management Centres for forecasting and balancing. Phase-I and Phase-II together target thousands of circuit-kilometres and added transformation capacity, part-funded by central grants.
How it helps: By smoothly evacuating wind and solar, it lets fossil generation be backed down, trimming coal use, carbon emissions and fuel imports, and supporting the 500 GW non-fossil goal for 2030.
Conclusion: The corridor is the grid backbone that turns scattered renewable potential into reliable, low-carbon supply.
What an examiner expects to see
- GEC is implemented by MNRE to evacuate renewable power into the national grid
- Intra-State GEC Phase-I (2015): ~9,700 ckm of lines and ~22,600 MVA substations across resource-rich states
- Intra-State GEC Phase-II (approved 2022): ~10,750 ckm of lines and ~27,500 MVA substations
- Inter-State GEC component adds long-distance lines and HVDC terminals, including the Ladakh evacuation link
- Includes Renewable Energy Management Centres (REMCs) for forecasting and grid balancing
- Funded partly by central financial assistance plus low-cost loans (e.g. KfW)
- Reduces curtailment, lets coal plants be backed down, cutting emissions and fuel imports
- Supports the 500 GW non-fossil capacity target by 2030
Concrete cases, schemes and judgments
- Intra-State GEC Phase-I and Phase-II
- Ladakh inter-state transmission link with HVDC terminals
- Renewable Energy Management Centres (REMCs)
- Solar and wind resource-rich states: Rajasthan, Gujarat, Tamil Nadu, Karnataka, Andhra Pradesh
