EPDK mandates 1-hour reporting for grid capacity changes

The Energy Market Regulatory Authority (EPDK) in Türkiye has introduced a binding regulatory requirement governing capacity disclosures. Under the new ruling, any changes in capacity resulting from unexpected equipment faults or scheduled maintenance must be publicly disclosed within 1 hour of the event taking place. Furthermore, final annual outage schedules and planned maintenance windows must be communicated as quickly as possible to ensure operational transparency.

For engineers and control room staff managing substations, transformers, and large grid connections, this decision significantly compresses the time available to log and report forced outages. High-voltage transformer trips, bushing insulation breakdowns, or circuit breaker failures often require immediate diagnostic assessments. Under the updated EPDK rule, facility managers can no longer hold off on market notifications while technical teams determine the exact root cause or assess physical damage. The operational status change must be published within 1 hour.

This shift creates a direct link between physical asset monitoring and regulatory compliance. Control room operators must establish automated notification bridges so that relay trips or supervisory control system alarms translate instantly into operational status updates. Waiting for field crews to inspect remote switchgear before making a disclosure will lead to compliance failures.

What this means for asset owners in Türkiye: Substation managers in Türkiye must update their emergency response protocols so that supervisory control trip signals immediately trigger market notification procedures. Operators can no longer wait for field engineers to perform manual transformer testing or diagnostic procedures before declaring a forced capacity loss, meaning automated operational workflows are essential to ensure compliance within the mandatory 1-hour reporting window.
