Maximum Generation

The Maximum Generation (Max Gen) service allows access to capacity which is outside of the Generator’s normal operating range in emergency circumstances.

Main text

Max Gen is required to provide additional short term generation output during periods of system stress for system balancing. This service allows access to unused capacity outside of the Generator’s normal operating range. This service will be initiated by the issuing of an Emergency Instruction in accordance with the Grid Code BC2.9.2, Section 4 of the CUSC and the Maximum Generation Service Agreement.
