When trial operation starts, it is the result of the power market auctions on both sides of the interconnector that determines how much and in which direction the power will flow. Trading on the interconnector starts the day before trail operation begins (30th September).
- The technical tests have been carried out as planned, and we are pleased to reach an important milestone for the North Sea Link project, says Executive Vice President Gunnar Løvås in Statnett. - Until now, it has been our need to test the interconnector that has determined the flow over the cable. From 1 October, the capacity will be available to the power market.
The cable was completed in early June, and on June 18, transmission between the two countries was tested for the first time. The test period is now over, and the interconnector is ready for a three-month trial period where the functionality will be verified and evaluated.
- A period of trial operation is important to ensure long term safe operation of the interconnector. Power exchange between countries is an important prerequisite for a zero-emission energy system in the future. Renewable energy production varies between different areas and sources, and power exchange will be increasingly important to ensure continuous access to enough power, says Executive Vice President Løvås.
The interconnector is built for a transmission capacity of 1400 MW. In order ensure the operational security of the Norwegian power system, the trial operation will begin with a maximum capacity of 700 MW. During trial operation, the maximum rate of change of power flow, so-called ramping, is set at 300 MW per hour. The market will be notified of capacity changes through market announcements.
North Sea Link is owned by Statnett and the British National Grid with 50 percent each. The connection has cost approx. 1.6 billion euros.
