On May 14, 2024, EU ACER issued Decision 07/2024 dated May 13, 2024, on CSAM amendments and said TSOs are required to update their ordinary contingency lists.
Updates must specifically include the loss of a single busbar coupler, whether protected by an overcurrent protection device or by an over-/under-voltage protection device.
These must be made within a year after new CSAM adoption, i.e. by May 13, 2025.
On Nov. 24, EU ACER began coordination methodology review.
EU ACER announced that it will make a decision on amending the methodology for coordinating operational security analysis in the electricity systems by May 2024
Follows EU ACER Dec. 2020, proposed changes to CSAM methodology, see #94264.
Background
On Nov. 17, 2023, European Network of Transmission System Operators for Electricity (ENTSO-E) submitted proposed methodology for coordinating operational security analysis (CSAM) amendment, on behalf of transmission system operators (TSOs),
Following receipt EU ACER has initiated a procedure to decide on these amendments.
CSAM supports EU operational security via requirements for: transmission system coordination; effective operational planning; information transparency and reliability.
Proposed Amendments
Proposals cover observability area implementation - TSO real time system monitoring/ modelling for operational security as per the Incident classification expert panel report.
Amendments aim to align observability area reassessment period with one for external contingency list (simulated items to test compliance with operational security limits).
Plus include busbar couplers in contingency lists/TSO individual grid models (IGMs) to ensure power flows stay within operational security limits after a contingency occurs.
Next Steps
EU ACER will decide on the TSOs’ proposals by May 2024.
