2022-2023 Imperfections Mid-Year Report V3.0

EirGrid and SONI are Transmission System Operators (TSOs). In this role, we take actions to ensure supply of power and system security to customers across the system in real time. The cost of these actions is known as the imperfections costs. We pay for these via the revenue we get from suppliers through the Imperfections Charges. The purpose of this report is to describe the analysis undertaken by the TSOs mid-way though the 2022/23 Tariff Year, analysing the imperfections costs against the revenue recovered for same.
