All Nordic countries have data hubs in place by 2023

In three years’ time it is estimated that all Nordic countries have data hubs that will facilitate wholesale and retail market processes. The successful implementation of data hubs and the ability to centralize the handling of market processes is a key factor for the Nordic retail market to work effectively.

The governments and regulators in all the Nordic countries have given the transmission system operators (TSOs) the responsibility to develop and operate the data hubs in each respective market. Today, data hubs are up and running in Denmark and Norway and under development in Finland and Sweden, with a scheduled start around February 2022 in Finland and, depending on the legislation, 2022/2023 in Sweden.

In this year´s report, NordREG concludes that none of the Nordic data hubs are integrated with the national comparison tool (CT), but end-users can access their hourly consumption data in Denmark and Norway. This will also be possible in Finland and Sweden.

NordREG believes that enabling customers to access actual consumption data when searching for a new electricity contracts can reduce the barrier to switch supplier. However, none of the Nordic TSO’s have found the need for this integration and has therefore not developed an interface for sharing data between data hub and CT.

In the report, the TSO’s from Denmark and Norway share valuable insights from implementing their data hubs, which could be useful in the work to implement the Finnish and Swedish data hubs. One of the main findings in Denmark and Norway is that it’s important to maintain close cooperation with the necessary regulatory authorities as well as with the market actors.

Invitation to comment on NordREG’s proposal for “Methodology for assessment of the Nordic forward market”

NordREG has been preparing a common approach on how to perform the upcoming analysis of the cross-zonal hedging opportunities in line with Commission Regulation (EU) 2016/1719 of 26 September 2016 establishing a guideline on forward capacity allocation (FCA GL) article 30.

Below you will find a link to the draft methodology, based on which the regulators are planning to conduct the upcoming study. All Nordic market participants are hereby invited to comment on the draft “Methodology for assessment of the Nordic forward market”.

NordREG is especially interested in hearing the stakeholders views on how the approach could be improved to better analyse the hedging opportunities in the Nordic markets. The background for the assessment is in the requirements in FCA GL article 30. The previous assessment was conducted in 2016-2017, please see links below.

The end objective is for regulators to assess whether there are sufficient hedging opportunities in the Nordic electricity market. If the hedging opportunities in two adjacent bidding zones are deemed insufficient, the regulators on each side of the bidding zone border must, in a coordinated manner, make decisions targeted at the TSO’s on each side to introduce long term transmission rights (LTTRs) or other measures to improve hedging opportunities.

The timeline looks as follows:

  • This current consultation on proposed evaluation method (May-June 2020).
  • Internal regulator assessments and decision on way forward (summer 2020).
  • Data collection, calculations, assessments and draft decisions. (the timeline and exact approach varies per country).
  • Consultations on the assessments and the hedging needs of market participants according to FCA art. 30(3)(a) (circa winter 2020-2021).
  • National decisions on whether there are sufficient hedging opportunities and coordinated decisions per bidding zone border on introducing LTTRs or not (deadline April 2021)*.

Last day for replies – 2 June 2020

Please send your views, comments, considerations etc. in writing to with copy to Please mark your answers to the consultation with the following reference number 2020-100867.

Per default replies are public, but if you wish to be anonymous, please indicate this.

Deadline for replies: 2 June 2020 EOB.

*As Norway has not implemented the FCA GL in national legislation at this point, the deadline for Norwegian borders will depend on the implementation time.

Questionnaire to stakeholders on parallel runs of the Nordic Flowbased

In July 2018 the Nordic Regulators approved the Flowbased Capacity Calculation Methodology (“flowbased”) for the Nordic Capacity Calculation Region (“CCR Nordic”) in accordance with Article 20(2) of Commission Regulation (EU) 2015/1222 of 24 July 2015 establishing a Guideline on Capacity Allocation and Congestion Management.

An important part of the legislation and of the flowbased methodology is that “the TSOs concerned shall test the new approach alongside the existing approach and involve market participants for at least six months”. To Nordic Regulators’ understanding, testing the flowbased alongside the existing approach implies to have market coupling results each day with flowbased capacity input alongside the market coupling results with the current capacity input. This is referred to in the CCR Nordic methodology as “parallel runs”, and have been agreed to be performed for at least one year before flowbased can go live.

The NEMOs, which own the market coupling algorithm, have stated there are obstacles to perform the parallel runs on the same day as the market coupling, and therefore they want to do the parallel runs with a delay of 14 days. The Nordic Regulators assume that this is not in line with what everyone had in mind about parallel runs. Thus, the Nordic Regulators would welcome input from the stakeholders, and we hope you will take your time to answer the following and help us.

Question 1: How would it affect your assessment and understanding of the flowbased to have a 14-days delay on parallel runs compared to having the parallel run on the same day as the market coupling?

Question 2: Do you expect to be looking at the parallel run flowbased results every day, during the parallel runs? If not, with what frequency do you expect to assess the flowbased results?

Question 3: What kind of other problems, if any, would you foresee in running the parallel run with a delay of 14 days?

The Nordic Regulators appreciate your feedback by email before the end of 28 April 2020.

The Regulatory Authorities of CCR Nordic refer proposals for a Nordic aFRR capacity market to ACER

The Regulatory Authorities of Capacity Region Nordic (the Danish Utility Regulator, the Finnish Energy Authority and the Swedish Energy Market Inspectorate) have decided to refer proposals on the establishment of a Nordic Market for frequency restoration reserves with automatic reserves to the Agency for the Cooperation of Energy Regulators (ACER).

The proposals were submitted by the Nordic Transmission System Operators for regulatory approval in accordance with the EU Regulation Establishing a Guideline on Electricity Balancing (EB GL). The purpose of the regulatory approval is to ensure that the proposals are compliant with the EB GL and other relevant EU legislation.

The Norwegian Energy Regulatory Authority has participated in discussions with the CCR Nordic NRAs on an informal basis pending the implementation of EB GL in Norway.

None of the revised proposals were found approvable by all of the CCR Nordic Regulatory Authorities. A unanimous approval within the deadlines in the EB GL is a prerequisite for approval at regional level.

As a consequence of the referral, ACER will now have to decide on the revised proposals within six months in accordance with the decision-making procedure set out in the ACER Regulation.

The referral letter to ACER with an accompanying document explaining why the proposals were not found approvable can be accessed here:

NordREG publishes recommendations on a common Nordic regulatory framework for independent aggregators

NordREG believes that aggregators have the potential to be a key enabler of the green and consumer-led energy transition and that a coordinated approach to developing a harmonized framework for aggregators will bring further benefits for the Nordic countries.

Aggregation shows great potential for enabling a more efficient and sustainable energy system by allowing consumers to shift demand away from peak and constrained periods. Aggregators can empower consumers to engage in and benefit from electricity markets, enable wide-scale and localized flexibility as an alternative to costly investments in network expansions and upgrades to help accommodate new demand and renewable generation.

The Electricity Directive of the Clean Energy Package requires EU Member States to develop a framework for independent aggregators that enables them to operate in all electricity markets. The directive defines ‘independent aggregator’ as a market participant that combines multiple customer loads or generated electricity for sale, purchase or auction in any electricity market, and is not affiliated to the customer’s supplier. Customers must be able to choose an independent aggregator that operates concurrently with the customer’s existing supplier, without consent from the existing supplier.

NordREG’s overall recommendation is that the regulatory framework for independent aggregators should be adequately harmonized in the Nordic countries and not be limited to one country. This will maximize economies of scale and scope, enable more competition, and allow innovation in demand response to flow across borders. The work on harmonization should assess whether the potential benefits of harmonization are proportional to the perceived costs. In order to achieve a harmonized framework for aggregators, NordREG recommends that the Nordic ministries develop a joint road map to coordinate the work of the relevant authorities.

NordREG has a number of more detailed recommendations related to the following topics:

  1. General market access for independent aggregators
  2. Direct financial responsibilities for energy imbalances caused
  3.  Compensation for unmatched positions caused by independent aggregators, and
  4. Measurement of flexibility

NordREG’s role is to advise on the regulatory framework in which independent aggregators can operate in all markets. The recommendations therefore seek to increase the possibilities for different aggregator models and not to limit them, thereby allowing market driven solutions. NordREG encourages market actors to innovate in this area and to come forward with new models of aggregation where they are efficient.

Stakeholder workshop on Independent Aggregation

NordREG is gathering the views of stakeholders with experience of aggregation. The first and most pressing issue we are seeking to address, is the new requirement to allow for ‘independent aggregators’ (IA) under the new Electricity Directive. NordREG is aiming to align our approach to the regulatory framework around independent aggregation where possible to minimise cross-border barriers. This raises a lot of questions around metering, settlement, balance responsibility, market design and how such a system of aggregation could work in practice.

NordREG publishes recommendations for how to implement new EU-legislation

Today, NordREG publishes 21 recommendations on how to implement some of the retail market related articles in the Clean Energy Package into national legislation. NordREG believes that a coordinated implementation will have an important and positive impact on the Nordic retail markets.

– The recommendations support the functioning of the retail market and the integration of the Nordic markets which are important factors for efficient competitive markets to the benefit of the consumers, says Carsten Smidt, Director of The Danish Utility Regulator, DUR, and this year´s Chair of NordREG.

NordREG is an organization for the Nordic energy regulators that promotes a legal and institutional framework and conditions necessary for developing Nordic and European electricity markets.

With NordREG´s long-term ambition to work towards a harmonized Nordic retail market in mind, NordREG has selected four retail market related articles in the new electricity directive as particularly important to implement in a similar way. The articles regulate basic contractual rights, fees related to switching, comparison tools and billing information.

When these articles are implemented in national legislation, NordREG recommends that:

  • Termination fees for fixed term, fixed price contracts should still be permitted, as long as the fees do not exceed the supplier’s direct economic loss of losing a customer.
  • Nordic energy regulators do not issue trust-marks for all comparison tools on the market, but instead ensure the quality of publicly driven comparison tools, according to the standard set by the new directive.
  • Five key contractual conditions shall be highlighted in a prominent and easily readable way in the beginning of a supplier contract.
  • Customers are able to choose their prefferd direct channel for information on contractual changes during the contract period.
  • All customers should be able to receive bills and billing information free of charge. There should be no billing fees for paper bills, but discounts may be allowed for customers that choose electronic bills.

NordREG also publishes several recommendations for how suppliers should present mandatory information on bills.

The published recommendations represent the views of the Nordic energy regulators. However, it depends on the national legislators in each Nordic country how these recommendations will be implemented.

About NordREG

NordREG is an organization for the Nordic energy regulators. Our mission is to actively promote legal and institutional framework and conditions necessary for developing the Nordic and European electricity markets. The basis for the co-operation within NordREG is to identify areas of work where cooperation can take the following forms: exchange of views, working together to map and analyze energy market issues, producing reports and statements and taking common action to influence the development of the Nordic or the European energy markets.
