Day-Ahead Market Transition to 15-Minute Time Unit Postponed
The transition of the day-ahead market to a 15-minute time unit, which was previously scheduled for June 11 this year, has been postponed to September 30. The postponement is due to shortcomings in the technical readiness of some parties to support the transition.
The proper functioning of day-ahead market processes is critically important for electricity market participants on a daily basis. Therefore, it is in the interest of all parties involved that all essential systems are fully prepared and thoroughly tested before the transition.
Elering’s systems are already fully ready to support the transition of the day-ahead market to a 15-minute time unit.
According to the rules of the Baltic capacity market for frequency reserves, the capacity market time unit must match the day-ahead market time unit. Consequently, the transition of the Baltic frequency reserve capacity market to a 15-minute time unit will also be postponed to September 30. Since the aFRR and mFRR energy markets already operate with a 15-minute resolution, this update does not affect them.
