Unmanaged EV charging that occurs at network and system peaks could add unnecessary electricity infrastructure investment, increasing bills for all customers. Investment in our networks is scaled to meet peak demands and has the potential to significantly increase electricity bills over the coming decades. It is important we take action to shift demand, where it makes sense, to avoid peak demand increases. Rewiring Aotearoa is very supportive of the efforts the Ministry of Business Innovation and Employment is taking to consider options to deliver a more flexible electricity system that will lower system costs for all consumers. Uptake of smart EV chargers is one way to manage peak EV demand and support a lower system cost. However we do not think there is a strong enough case to mandate that all fixed EV charging units sold in New Zealand must be smart.
