Generator configurations range from low to high resilience and the choice should follow the overall risk assessment and be consistent with the distribution strategy; they are guidance, not a restriction on innovation. The reliability of a duplicated DNO supply used as a secondary supply should be risk-assessed. Areas (or whole facilities) the risk assessment identifies as needing resilience will always need some form of secondary supply, and the Group should agree where secondary supplies are required. Making CHP or generation the prime source should be considered against the overall risk strategy; CHP is not to be the only secondary supply.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
