Syllabus: GS3/Renewable Energy/Infrastructure Insufficient transmission lines have emerged as a major obstacle to India’s rapid expansion of renewable energy capacity. Close to 21 gigawatts (GW), that is about 9% of the country’s installed renewable energy capacity, is currently transferred from plants through temporary grid connections while awaiting dedicated transmission infrastructure.
Syllabus & Relevance
Prelims: Environment — institutions, terminology and factual features connected with the development.
Mains: GS-3 — contemporary application of the relevant syllabus theme.
Current–static link: Revise the underlying institution, policy or concept together with this development.
Why it matters for India
Insufficient transmission lines have emerged as a major obstacle to India’s rapid expansion of renewable energy capacity.
India’s solar and wind capacity has expanded rapidly, but transmission infrastructure in some renewable-rich regions has not kept pace.
This is particularly important because India’s major renewable-energy resources are concentrated in specific regions.
Delay in Renewable Targets: Transmission bottlenecks can slow the effective utilisation of India’s rapidly expanding renewable capacity, potentially affecting the achievement of its 2030 clean-energy and climate targets.
Static Foundation
Close to 21 gigawatts (GW), that is about 9% of the country’s installed renewable energy capacity, is currently transferred from plants through temporary grid connections while awaiting dedicated transmission infrastructure.
Of this, around 12 GW faces restrictions on “power evacuation” during periods of peak solar generation.
Power evacuation is the process of transferring electricity generated at a power plant to the consumption point.
During the financial year 2025-26 (FY26), around 6,900 gigawatt-hour (GWh) of clean electricity faced restrictions due to a mismatch between the rapid pace of renewable energy deployment and commissioning of associated transmission infrastructure.
Industry executives also cautioned that these projects could turn into non-performing assets (NPAs) if the government doesn’t address the issue.
Electricity generated at a power plant has to travel through transmission lines before reaching distribution networks and ultimately consumers.
The basic chain is: From Renewable Energy Project to Transmission Network to Distribution Network and ultimately to Consumers.

Mains Perspective
Background and key dimensions
- Power evacuation is the process of transferring electricity generated at a power plant to the consumption point.
- During the financial year 2025-26 (FY26), around 6,900 gigawatt-hour (GWh) of clean electricity faced restrictions due to a mismatch between the rapid pace of renewable energy deployment and commissioning of associated transmission infrastructure.
- Industry executives also cautioned that these projects could turn into non-performing assets (NPAs) if the government doesn’t address the issue.
- Electricity generated at a power plant has to travel through transmission lines before reaching distribution networks and ultimately consumers.
- The basic chain is: From Renewable Energy Project to Transmission Network to Distribution Network and ultimately to Consumers.
- India’s solar and wind capacity has expanded rapidly, but transmission infrastructure in some renewable-rich regions has not kept pace.
- This is particularly important because India’s major renewable-energy resources are concentrated in specific regions.
- Electricity generated in these regions may have to travel hundreds or thousands of kilometres to reach major demand centres.
- Current Infrastructure for Grid Transmission
- General Network Access (GNA) Framework: It is a temporary arrangement that allows renewable energy plants to use whatever spare transmission capacity is available while they wait for their permanent transmission connection.
- T-GNA projects, however, can schedule power only if spare transmission capacity is available.
- Concerns: During periods of network congestion, long-term GNA projects receive priority, often resulting in curtailment of generation from **T-GNA-**connected plants.
Analytical use
- Connect the development with its institutional, policy, economic, social, environmental or security implications only where supported above.
- In a Mains answer, separate the verified development from broader evaluation and use the named evidence precisely.
Way forward
