India’s power regulator has warned that several solar and wind projects could be disconnected from the national grid if they continue to violate key technical requirements meant to keep the system stable.

The Central Electricity Regulatory Commission (CERC) issued the caution after the Northern Regional Load Despatch Centre reported repeated breaches of ride-through norms — rules that require renewable plants to stay connected during sudden dips or surges in voltage. These standards are essential to prevent generation from dropping off during faults, which can trigger wider instability.

According to the regulator, only a small number of renewable projects have fully met the compliance requirements. Some plants have not submitted the mandatory self-audit reports, while others continue to trip during voltage disturbances despite earlier warnings and meetings held to correct the problem.

CERC has now directed the Northern RLDC and the Central Transmission Utility to establish a clear process for dealing with persistent offenders. The proposed measures include stricter monitoring, fresh compliance reviews and, if necessary, disconnecting plants that fail to follow the grid code.

The regulator said maintaining grid discipline is becoming increasingly important as India rapidly expands its renewable capacity to meet its 2030 clean-energy targets. Ensuring that solar and wind plants remain stable during grid fluctuations, it added, is crucial for protecting overall power system reliability.
