The Single Electricity Market (SEM) is the wholesale electricity market for the island of Ireland, covering both Ireland and Northern Ireland. Established to create a single, integrated market across two jurisdictions, the SEM supports the secure and efficient supply of electricity to homes, businesses and public services across the island.
Our SEM at a Glance brochure provides an accessible introduction to the market, explaining its purpose, the benefits it delivers for consumers, and its role in supporting competition, security of supply and the transition to a lower-carbon energy system. It also outlines the role of the Single Electricity Market Committee (SEMC), the decision-making authority for all SEM matters, in overseeing and shaping the market for the benefit of consumers.
