The Nordic Balancing Steering Committee (NBSC) has decided on a timetable for single balance - single imbalance price model. The model is proposed to be introduced in Q2/2021 (2 October 2019).
The implementation model is based on an assumption in which dual imbalance price model can be applied on imbalance settlement periods with divergent balancing directions. If the TSOs together with stakeholders cannot find a methodology with dual pricing in certain ISPs, the implementation of single pricing may be delayed until the introduction of 15 min ISP. The purpose with dual pricing on specific ISPs is to mitigate overreactions by self-balancing.
When making the decision NBSC took into consideration a strong stakeholder position, legal boundaries and operational concerns. The single balance - single imbalance price model is part of the Nordic Balancing Model (NBM) roadmap which is in progress and which aims to implement the project in stages.
The TSOs’ preparatory report on the single pricing reflects the different options, operational concerns and mitigation measures. The report has been used as background material for decision-making. We will continue discussing the issue at the next Nordic Stakeholder Reference Group meeting at the end of November, in particular the details and conditions for dual pricing on imbalance settlement periods with divergent balancing directions. High quality production plans are also important for TSOs, how the quality of these plans is ensured will be discussed with the stakeholders.
