Aggregator

An aggregator is an organisation that combines many small energy assets into a single portfolio large enough to participate in electricity markets. Individual depots are usually too small to qualify on their own, so an aggregator is the normal route for a fleet to reach flexibility revenue. In Great Britain an aggregator taking assets into the Balancing Mechanism is registered as a Virtual Lead Party under the Balancing and Settlement Code, a route open since 2019; there is no aggregator licence.
