EC imposes obligations on TenneT to increase electricity capacity between Denmark and Germany
TenneT will ensure that a specific guaranteed capacity is available at all times.
The Commission opened a formal investigation on 19 March 2018 to assess whether TenneT infringed EU antitrust rules by systematically limiting southward capacity at the electricity interconnector between Western Denmark and Germany.
The Commission had concerns that through this behaviour TenneT discriminated against non-German electricity producers. This conduct prevented the export of cheap electricity from the Nordic countries, where it is largely generated from renewable energy sources (mostly wind and hydro) to Germany, leading to less competition between electricity producers on the German wholesale market and therefore higher electricity prices. .
If confirmed, such behaviour would also be contrary to the creation of an integrated Energy Union where energy flows freely across borders based on competition and the best possible use of resources.
Following the opening of the formal antitrust investigation, TenneT offered commitments to address the Commission's concerns. The Commission then consulted market participants to verify whether the proposed commitments were indeed liable to remove the competition problems identified by the Commission.
In light of the market test results, the Commission is satisfied that the following commitments, proposed by TenneT, address its concerns, and has made them legally binding on TenneT:
- TenneT will make available to the market the maximum capacity compatible with the safe operation of the interconnector between Western Denmark and Germany and, in any event, will guarantee a minimum hourly capacity of 1 300 megawatts on the interconnector (around 75% of its technical capacity). This minimum guaranteed hourly capacity will be reached following an implementation phase of up to six months.
- Following the planned expansion of the interconnector between Western Denmark and Germany in 2020 (the East Coast Line project) and 2022 (the West Coast Line project), TenneT will progressively increase the guaranteed hourly capacity to 2 625 megawatts by 1 January 2026.
- TenneT can reduce the capacity offered below the minimum guaranteed level only in a very limited number of exceptional circumstances, when no other option is available to ensure the security of the high-voltage electricity network.
The commitments will remain in force for nine years and a trustee will be in charge of monitoring TenneT's compliance with the commitments.
If TenneT were to breach the commitments, the Commission can impose a fine of up to 10% of the company's worldwide turnover, without having to prove an infringement of EU antitrust rules. ■
