Government and Ofgem to ensure that smart charging delivers benefits to consumers whilst ensuring electricity system security.
Smart charging systems can be complex with multiple parties, including the network and system operators, energy suppliers and aggregators, requiring the ability to modify the charging programme of an EV or groups of EVs. There is currently no industry code governing the order of precedence that would be applied in the event that more than one party requests control of an EV’s charging at the same time. Precedence could be governed by a market or by deterministic rules. It is also expected that consumers will expect clarity about which party has the ability to modify their EV’s charging programme and, in the event of the programme being modified, which party was responsible.
A lack of coordination and visibility in terms of which parties are exploiting flexibility from smart chargepoints, might lead not only to missed opportunities for electricity system efficiency and monetary benefits for EV drivers, but also risks to electricity system security and stability.
Ofgem and Government, should ensure that:
Government and Ofgem, through the electricity industry technical and market code governance frameworks, should ensure overall operational coordination of industry parties seeking to exploit EV flexibility through smart charging technologies and electricity market products by 2021. Clear visibility as to which market products are in play must be evident to both industry and users at any time, as well as which transactions have occurred over a settlement period. It must also ensure that the operation of smart charging does not present a risk to the stability of the electricity system.
