(Netavison 🙂 Statnet is now working on finding measures to protect the power supply in Norway this fall and winter. In the worst case, your power can be disabled for periods of time.
– For some customers, the security level of the supply may be somewhat small, so the risk of power outage is slightly higher. If you switch-off by zone, you will be without power for a few hours, says Peer Olav Ostli du Netavisen, Statenet’s Executive Vice President for System Operations, and emphasizes:
– but this comes only after a number of other measures have been taken to protect the power supply.
Østli says Norway has had no recent electricity supply (by the usual definition).
– There is a case in northern Norway, where due to faults in the network, consumption zone disconnection had to be introduced in 2010, he says.
But we’re not there yet. First, other measures will be introduced to prevent Statenet from resorting to electricity supply.
Got marching orders
– We have a reservoir, historic lows, high prices in the Nordic region and high gas prices characterize the electricity market in Europe. That is why we are now asking Statnett to examine the need for future measures to deal with the tighter power situation, Inga Nordberg, director of the Energy and Licensing Department at NVE, said before the weekend.
The report comes in the wake of dire warnings from many quarters about the power crisis. Among other things, at the same time that electricity exports from Norway were in full swing, from Statnet itself, the alarm sounded and warned of the danger of electricity supply (L.Here is the own case)
– With below-normal inflows and a cold and dry winter over the next six months, Norway may need significant net imports until the ice begins to melt in the spring of 2023. Then there is the risk of exporting Europe’s energy. A further escalation of war and conflict with Russia could affect gas supplies in Europe. This uncertainty is compounded by the ever-present risk of failure on one or more international links. As a result, Statnet has changed the assessment of southern Norway’s power status (NO1, NO2 and NO5) from normal (green) to tight (yellow) for the upcoming bottling season, says Østli.
– I emphasize that producers are not without responsibility. “They have a significant social responsibility to follow and I now expect them to be able to guarantee that they have followed this social responsibility,” Energy Minister Terje Ausland (Labour) said before the weekend.
Shut down reserve power stations
– We will now, on behalf of the NVE, study operations in a very tight power scenario (SAKS). It is too early to say anything concrete about what we are proposing, but we would like to point out that we have a number of measures that can be implemented in advance to avoid ending up in such a situation. Østli also said that it is important for power producers to take into account that there may be a situation where electricity imports are less likely than usual in the future.
In 2014, StatNet developed a large assessment of tools for dealing with extremely difficult power situations (SAKS). This statement. The report said that the risk of power outages will be low in 2020 and further into 2030. StatNet anticipated growth to reduce the risk of electricity crisis, not growth towards the current situation.
Important operations in 2014 included the reserve power plants Nyhamna and Tjeldbergodden in Møre- and Romsdal. These gas-fired power plants had to provide additional electricity to central Norway (NO3), as there was a high risk of a very stressful power situation there. Today, central Norway is not affected by high electricity prices, but can still enjoy low electricity prices. Today, the reserve power station at Tjeldbergodden has been sold and Nyhamna is to be sold. StateNet is no longer licensed by the Authority to use reserve power stations as SAKS operations. Due to limitations in the power infrastructure, these power plants could not be used to cover the demand in the south of Norway.
New automated solutions
Therefore, one of the key measures of the Statnett 2014 report is: energy options. When buying energy options, StateNet has to pay large electricity consumers not to use electricity for a certain period of time. One such consumer could be aluminum plants, which consume large amounts of electricity in aluminum production.
StateNet, together with Tibber and Entelios, looked at how automated solutions enable the use of electric cars and panel heaters in private homes and ventilation systems in large buildings to achieve the necessary balance in electricity supply.
If SAKS measures are still insufficient, Statnett should introduce electricity rationing. Statenet will then follow the rules on power distribution (Here it is)
– Could this have been avoided if Norway had used less water in its reservoirs to produce electricity for export?
– It is important to emphasize that most of the electricity produced in Norway is used here at home. Approximately 77 TWh of electricity produced in Norway in 2022, about 7 TWH exported. It is the responsibility of producers to dispose of water for electricity supply at all times, so we have declared that it is important for power producers to include the uncertainty surrounding possible imports in autumn and winter, says Østli.
