Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, what assessment he has made of the (a) frequency of power surges when Distribution Network Operators erroneously supply electricity outside the allowed fluctuations and (b) potential effect of those fluctuations on the safety of electric vehicle charging points; and if he will make a statement.

The Electricity System Operator is responsible for keeping the overall frequency and voltage of the GB electricity network within the statutory limits and publishes annual data on system excursions. Conditions on the electricity distribution network, or internal wiring at a premises, can alter the voltage at a specific Electric Vehicle (EV) charging point. EV charging points are designed to operate over wide voltage and frequency ranges. They are also fitted with internal protective devices to limit damage should excursions exceed safe limits. Should any customers have concerns about voltage management at their premises, they can raise them with their Distribution Network Operator for investigation.
