CEA (Technical Standards for Connectivity to the Grid) Regulations, 2026 — draft

Comments due: 2 September 2026

CEA proposes new grid connectivity standards for RE, hybrid and storage connecting at 33 kV and above, including ride-through, grid-forming and black-start requirements for large batteries.

Why it matters. Moves grid-support duties onto inverter-based plants as their share of the grid grows.

What changes

Covers renewable, hybrid and storage plants connecting at 33 kV and above; replaces the 2007 standards.
Low- and high-voltage ride-through required for all generating units.
Battery storage of 50 MW and above: automatic generation control, grid-forming and black-start capability, plus voltage and frequency response.
Every unit needs a Unique Registration Number from CEA's e-GEN portal before grid connection.
Non-compliance can lead to disconnection and action under Section 146 of the Electricity Act.

Who is affected

RE developers · BESS operators · Hybrid plants · HVDC and FACTS operators · Transmission licensees
