English translation of press release, April 12, 2023
The case dates back to December 2018 when Nordjyllandsværket had problems with vibrations on the turbine at Block 3. This led to several outages on the turbine and numerous attempts to restore connection to the electricity grid.
Nordjyllandsværket notified the electricity market that Nordjyllandsværket was unable to supply electricity to the grid. However, due to a human error, it was not stated in the message, that the available capacity was now 0 MW. Therefore, it could potentially be misunderstood whether Nordjyllandsværket could still produce electricity, even though the message was that Nordjyllandsværket was unavailable. As soon as the mistake was discovered, Nordjyllandsværket informed the market.
"It is a human error that occurred in a situation where Nordjyllandsværket had to restore production during repeated outages on the turbine. It is unfortunate, and we are very sorry about it. But we do not believe that it has affected the market," says Jesper Høstgaard-Jensen, Technical Director of Aalborg Forsyning.
Regardless of this, the Danish Utility Regulator has now chosen to report Nordjyllandsværket to the police for possible insider trading.
Nordjyllandsværket is very aware of complying with the guidelines in the electricity market, which are described in detail in instructions and procedures. It is a case dating back to 2018, which has no connections to the current energy crisis, and no employees or managers in Aalborg Forsyning have or have had bonus schemes in connection with energy trading.
"To ensure that something similar does not happen again, immediately after the episode in 2018, we increased our attention to this area and initiated additional training in handling the guidelines," Jesper Høstgaard-Jensen explains.
The Danish Utility Regulator received information about the case in December 2018, and contacted Aalborg Forsyning about the incident in April 2021. Aalborg Forsyning has since worked closely with the Danish Utility Regulator to shed light on all aspects of the case.
