Supplementary notes

Positive values represent supplies to the GB system. This includes electricity produced by GB power stations and imports via interconnectors. Negative values represent supplies from the GB system (excluding end consumer demand). This includes power demanded by GB power stations and exports via interconnectors.

Pumped storage is expected to have a negative value since it does not generate electricity on its own, but rather stores electricity for use during high demand periods at the cost of using some energy itself.
