Import limitation

Import limitation controls electrical demand so a site does not draw more power from the distribution network than its agreed limit permits. In EV charging, this can involve reducing charger power when the rest of the site's demand rises. Import limitation is particularly useful where the theoretical combined demand of the chargers and other equipment is higher than the capacity that can be imported at the connection point. The control system prevents that worst-case total from occurring in practice. Under G100, import limitation can form part of a Customer Limitation Scheme where the DNO has agreed that current at the connection point must be restricted.
