How transmission bottlenecks are threatening India’s renewable energy projects

India’s rapidly expanding renewable energy sector is grappling with a major challenge: transmission constraints. 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, exposing developers to revenue losses and raising concerns over the financial viability of several projects. 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 betw
