Decision on SEM Testing Tariffs 2024

Decision on SEM Testing Tariffs 2024

Today, 27 September 2023, the SEM Committee publishes its Decision approving the SEM Testing Tariff rates that will apply to Generator Units Under Test (GUUT) from 1 January 2024.

The SEMC Decision is based on the TSOs’ Recommendation paper, which is published alongside this Decision.

The SEMC has decided to make no changes to the 2024 SEM Testing Tariff rates from the approved 2023 SEM Testing Tariff rates, other than to apply inflation.

The RAs are currently engaging with the TSOs on a more detailed review of the testing tariff methodology ahead of the consultation on the 2025 rates next year.
