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.
