Based on the results of the user acceptance tests and testing experiences with selected testing partners the project has concluded that the new imbalance settlement system is not yet performing as well as expected. Therefore it is not possible to initiate the Operational Test Runs (OTR) within the whole Nordic Market as initially scheduled.  A new time schedule will be prepared to mitigate identified risks and to ensure the successful roll-out in involved countries. More information will follow during September.   


–We have also assessed the status and readiness of the NBS stakeholders and come to the conclusion that the delay of the launch is necessary. Many market participants have indicated a need for additional time for operative and IT related preparations, says Minnakaisa Ahonen.  


During autumn 2015 validation and preparation of market structure data will continue actively between market participants and eSett. The commissioning plan will be updated according to the new time schedule during September. The updated commissioning plan will be available on the website

About the Nordic Balance Settlement project

The Finnish, Norwegian and Swedish Transmission System Operators (TSOs) Fingrid , Statnett and Svenska kraftnät have decided to implement a common imbalance settlement service for the Nordic electricity market. For this purpose, the TSOs have developed a new harmonized imbalance settlement model and founded the jointly owned service company eSett Oy to run the common imbalance settlement.
