ACER's 43rd REMIT Quarterly Outlines Cross-Border Investigation Rules and 2026 Compliance Priorities
SHERIDAN, WYOMING - April 13, 2026 - The Agency for the Cooperation of Energy Regulators (ACER) has published the 43rd edition of its REMIT Quarterly, centering on newly established Rules of Procedure that define the procedural framework for ACER's cross-border investigatory mandate under the EU's wholesale energy market integrity regulation. The publication follows a 2024 legislative update that granted ACER expanded authority, including direct power to investigate cross-border market manipulation cases. With 456 REMIT breach cases under review at the close of Q4 2025, the operational scale of enforcement has grown substantially, making the procedural ruleset a critical reference for compliance and legal teams across European energy markets.
