The Central Electricity Regulatory Commission (CERC) has issued the Connectivity and General Network Access (Third Amendment) Regulations, 2025, revising key aspects of the 2022 framework.

The amendment redefines critical terms such as cluster of ISTS substations and connectivity grantee, improving clarity and operational efficiency. It restructures bank guarantee requirements and introduces detailed compliance obligations for renewable generating stations and energy storage systems. The regulations also distinguish between solar and non-solar hours for injection scheduling, aligning transmission access with renewable energy variability.

These changes aim to streamline interstate transmission connectivity, enhance planning, and facilitate better integration of clean energy sources across India’s power grid. The move supports the evolving energy landscape by providing clearer regulatory mechanisms and improving scheduling flexibility for solar and non-solar generation.
