European market integration

Changes to Single Electricity Market (SEM) designed to create a competitive market across Europe and ensure compliance with the European target model.

Integrated Single Electricity Market

A redesign of the current Single Electricity Market (SEM) is required because of changes to European legislation that are designed to harmonise cross border trading arrangements across all European electricity markets.

These changes are designed to create a competitive market across Europe and require compliance with a European ‘target model’ that will link the separate markets.

The new wholesale market will be known as the Integrated Single Electricity Market (I-SEM).

Compliance

Compliance with the European Target Model and development of new market arrangements are the responsibility of the member states.

The Department for the Economy and the Irish Department of Communications, Energy and Natural Resources (DCENR) have charged the SEM Committee with developing these new market arrangements.

The SEM Committee was created as the governing body of the current Single Electricity Market and its membership is drawn from the Utility Regulator (UR) in Northern Ireland, the Commission for Energy Regulation (CER) in Ireland and expert independent members.
