NordBalt electrical connection announces scheduled maintenance shutdown

, Nov. 4 (Xinhua) — The NordBalt submarine cable connecting the power grids of and will be temporarily shut down next week for annual maintenance, Litgrid, Lithuania’s electricity transmission system operator, said on Friday.

The interconnection will be offline from 07.00 on November 7 to 18.00 on November 13 local time.

Maintenance will be carried out at NordBalt’s converter stations in Klaipeda and Nibru, Sweden, according to Litgrid’s Managing Director (CEO) Rokas Masiulis.

The scope and frequency of maintenance is based on the instructions from the manufacturer of the inverter equipment and Litgrid’s Transmission Network Operation Regulation.

Since some premises cannot be accessed and inspected while the inverter is running, maintenance can only be carried out when the inverter is switched off.

The work was originally scheduled for August 29 to September 4, but as electricity prices climbed to record highs in August, Litgrid and Sweden’s electricity grid operator Svenska Kraftnat agreed to postpone it for more than two months.

Lithuanian Energy Minister Dainius Kreivys told the Baltic News Service (BNS) that the NordBalt cable is crucial for the import of Scandinavian electricity from Sweden. Therefore, the temporary shutdown would reduce import volumes and have a negative impact on the already high market price of electricity.

NordBalt’s total market availability was 100 percent during the first nine months of this year when 3.8 terawatt hours (TWh) of electricity were imported from Sweden to Lithuania, which corresponds to approximately 44 percent of Lithuania’s total imports, according to Litgrid.

700 megawatt (MW) interconnection with Sweden has been in operation since 2016.
