[CWE FB MC DA] | SPAIC publication - Impact assessment for the planned outage of two Belgium-France 380 KV cross-border lines
Dear Market Participants,
RTE & Elia plan grid reinforcement on the two 380 kV cross-border lines between Avelgem (Elia) and Avelin (RTE) - Mastaing (RTE) substations. More specifically, the pylons of the lines are being replaced and the foundations reinforced, in anticipation of an upgrade of the AMS conductors with high-performance HTLS conductors that will be performed starting from 2020 and is expected to be finalized in 2022.
The simultaneous outage of the interconnectors is currently planned to start on 04/03/2019 and is expected to end on 29/03/2019. The most recent information regarding the outage period can be retrieved from the ENTSO-E Transparency website (https://transparency.entsoe.eu/).
Following the continuous effort for enhanced transparency at CWE, RTE and ELIA have performed a SPAIC analysis. SPAIC stands for Standard Procedure for Assessing the Impact of Changes and consists of a comparison of the CWE flow-based domains for typical “reference” days, commonly predefined by CWE TSOs, in order to estimate the impact of a change in grid topology or flow-based parameters in the CWE Area. Since the outage is only planned during winter and spring period, the impact was only assessed on a reduced number of typical days (8 out of a total of 12).
The enclosed documents provide the results of the performed SPAIC analysis for the reference period.
Best Regards,
RTE & Elia
