EV aggregators

Overview of the status and impact of the innovation

Innovation 2


Aggregators combine different DERs and operate them as a single entity, such as a virtual power plant. They can add multiple benefits to the grid through services such as load shifting, balancing for TSOs and local flexibility for DSOs. As digital intermediaries between a pool of EVs and the power system operator or electricity market, aggregators are fundamental for enabling EV participation in electricity and ancillary service markets. They may be owned by an independent company or an energy retailer.


A single EV cannot meaningfully participate in markets or provide grid services. But a pool of EVs can offer major benefits, while also enabling new business models. Aggregators can stack different services from EVs to extract more value from several possible revenue streams, or aggregate pools of EVs with other assets such as stationary batteries or controllable loads to yield even more value.

In the world’s largest residential V2G trial, Project Sciurus is aggregating 320 V2G charge points in the UK to support the grid and generate revenues. The V2G units are aggregated, optimised and scheduled via the Kaluza Intelligent Energy platform; they participate in the UK’s Piclo demand-response market. EV owners are paid for every kilowatt hour that is exported (UK Power Networks).
