REMIT Article 4 Threshold Concerns for Energy Traders
Summary
Ofgem has published a policy position identifying concerns with the use of fixed thresholds (particularly 100MW) for determining whether outage and availability information constitutes inside information under REMIT Article 4. The regulator states that threshold-based approaches may fail to account for prevailing market conditions, cumulative impact of multiple smaller outages, or aggregation of information held by individual market participants. Ofgem clarifies expectations for all market participants, including Offshore Transmission Owners (OFTOs), and encourages review and updating of internal compliance procedures.
