Imperfections Charge 2020/21 and Reforecast Report 2018/2019 Decision Paper

The Regulatory Authorities, in Northern Ireland and Ireland are today, 27 August 2020 publishing the Imperfections Charge decision paper.

SONI and Eirgrid, together the Transmission System Operators (TSOs) for the all island Single Electricity Market (SEM), control the transmission of electricity and the management of various network constraints. These network constraints create additional costs within the SEM, as the TSOs are required to allow for such constraints in real time and increase or decrease individual generator’s output of electricity to ensure the balance between supply and demand of electricity is maintained at all times.

Constraint costs are recovered through the Imperfections Charge and this Decision paper details the Imperfections tariff to be applied in the 2020/21 tariff year.

Responses to the Consultation paper (SEM-20-046) are attached as appendices and have been duly considered when making the decisions contained within this paper.
