G100

Also called: EREC G100, Engineering Recommendation G100 G100 is an Energy Networks Association engineering recommendation for customer import and export limitation schemes connected to Great Britain's electricity distribution networks. It applies where there is an agreed need to restrict current at the connection point or prevent distribution-network voltage limits being exceeded. The current document is EREC G100 A2 Issue 2, published in April 2023. Its scope includes new load as well as generation, which makes it relevant to EV charging sites where additional demand would otherwise exceed an agreed connection limit. A G100 arrangement can use a Customer Limitation Scheme to monitor conditions at the connection point and control relevant equipment so the agreed import or export limit is maintained.
