Transmission Bottlenecks Threaten India's Renewable Energy Growth
India is building a lot of solar and wind power, but the wires that carry the electricity to homes are not ready fast enough.
About 21 gigawatts of power can’t be sent out right now, and 12 gigawatts are especially stuck during sunny times.
This means plants can’t sell all the electricity they make, losing money.
The problem is worse for projects that are waiting for permanent connections, called T‑GNA.
Because of this, some developers are worried their projects might become bad loans, and they have asked the government for help.
21 GW of renewable capacity is limited by temporary grid connections.
12 GW faces power evacuation restrictions during peak solar, causing up to 70‑80% curtailment.
In FY26, 6,900 GWh of clean electricity was curtailed due to transmission mismatches.
T‑GNA projects are deprioritized, risking financial viability and potential NPAs.
SPDA has requested financial relief from MNRE, citing delays in transmission infrastructure.
