The Nordic Transmission System Operations have decided to switch from 1 hour to 15 minutes imbalance settlement period.
The go-live date for the 15-minute imbalance settlement period (ISP) will be on Monday May 22, 2023 at 00.00 CET, at the beginning of an imbalance settlement period.
The transition to 15-minute imbalance settlement also means that it will be possible to trade with 15-minute products in the Nordic intraday and balancing markets. Energy metering will, to some extent, move to 15-minute intervals, based on local legislation/regulation.
Moving to higher time resolution in the Nordic imbalance settlement will mainly affect the following aspects of the imbalance settlement:
- Changes in data exchange ediel.org – quarterly resolution for reporting
- Calculation of imbalances will be done for each 15 min ISP
- Settlement data may be viewed additionally with 15-minute resolution
For additional information, please see the webinar on the impact on imbalance settlement and its processes and dataflows nordicbalancingmodel.net.
A commissioning plan for market participants will also be provided at the beginning of 2022.
