BERC (Electricity Grid Code) Regulations, 2023
The Transmission System frequency shall normally be 50.0 Hz and shall normally be controlled in the range 49.5 – 50.5 Hz (50 Hz ± 1%).
Voltage variation on the Transmission System shall normally be ±5% for 400 kV, ±6% for 230 kV and 132 kV buses during normal operations, and ±10 % at 400 kV, + 10%-15% for 230 kV and 132 kV buses during emergencies.
The procedure for International Connection to the Grid and the execution of agreement for the same shall be done by the Licensee in consultation with the Single Buyer and the Line Ministry

Grid Code Regulation 2024
The interconnection between a User’s system and the Transmission System at the Connection Site shall be controlled by the circuit breaker capable of interrupting within the short-circuit current range approved by the Transmission Licensee or System Operator.
Hydropower-generation units with Francis Turbines shall be capable of continuous stable operation at any Load between 50% and 100% MCR; while Pelton Turbines and Kaplan Turbine shall be capable of continuous stable operations at the Load between 30% and 100% MCR and 70% and 100% MCR respectively at normal operating head.
The Generating Units shall be capable to generate or absorb Reactive Power within their respective capability limit without compromising the active generation.
