Updated input data and assumptions for CBA LER according to art.156(11) SO GL for CE TSOs

Overview

The consultation is about the update of inputs for the Cost-Benefit Analysis (CBA) for the definition of a minimum activation time period for LER (TminLER) in Continental Europe Synchronous Area (Art.156(11) SO GL). This update is requested by CE NRAs to consider recent developments in Frequency Containment Reserves (FCR) costs and CE power system behaviour. The updated inputs will reflect the most recent frequency data, advancements in Limited Energy Reservoir (LER) technology, and changes in the CE power system. This will ensure a more accurate and up-to-date CBA, leading to a more effective Tmin LER definition that can better maintain steady-state frequency during alert states.

Why your views matter

Stakeholder feedback is crucial in updating the CBA's input for the definition of Tmin LER. Insights into recent developments on these topics can help ensure a more accurate and effective Tmin LER definition.

The Project Team will organize a workshop in ENTSO-E offices on 8 May 2024. The Project Team will present the proposal, and foresee time to answer questions of participants. Any stakeholder willing to attend the workshop physically or remotely can contact  FCRbyLER@terna.it to receive an invitation.
