Questions and answers about electricity shortages
Last update on 7th of September at 3 pm.
REGARDING ELECTRICITY SHORTAGES IN GENERAL
An electricity shortage occurs when electricity production and imports are not enough to cover electricity consumption. Electricity shortages can arise in several ways:
- As a consequence of a long period of freezing temperatures. Finland’s electricity consumption is highly dependent on the temperature. When the temperature drops by one degree, it causes an estimated 150 megawatts of additional electricity consumption.
- As a consequence of a sudden disturbance that causes an important power plant or electricity transmission link to be unavailable.
- A combination of the above, when a power plant or transmission link suddenly develops a fault during a period of freezing temperatures.
The factors affecting the onset of an electricity shortage are as follows:
- The discontinuation of electricity and gas imports from Russia to Finland.
- The possibility of delays to the commercial commissioning of Olkiluoto 3 (1,600 MW).
- The state of Nordic reservoirs. The Nordic power system is dominated by hydro power, and the reservoirs are lower than normal following a dry summer. The situation may improve or deteriorate, depending on precipitation in the autumn.
- Faults in the transmission links with neighbouring countries.
- Electricity shortages or a scarcity of electricity in neighbouring countries, meaning that electricity cannot be transmitted to Finland.
- Unforeseen disturbances in power plants.
Fluctuations in renewable energy output. The proportion of electricity generated cleanly using wind or solar power is increasing. Variable energy production can lead to lower wind power output when there is no wind and reductions in solar power output.
The risk of an electricity shortage is lower if the winter is mild and windy and if less electricity is consumed by industrial plants and households. When industries and consumers reduce their electricity consumption (demand-side management), it can help keep the power system in balance. Even minor electricity reduction measures affecting a large number of consumers can have a positive effect on the overall state of the power system.
Disconnection plans have already been made for use in the event of an electricity shortage. These ensure that the most critical consumers – such as hospitals – are not disconnected. For households, an electricity shortage may result in occasional power cuts lasting an hour or two at a time. Power cuts may occur again later on.
Power cuts will rotate, so they will occur in different places around Finland. Fingrid will notify each distribution system operator of how much power must be disconnected. After this, the local network operators should implement electricity distribution outages in a rotating fashion.
Efforts will be made to avoid electricity distribution outages affecting consumers for as long as possible, and consumers will only have their power disconnected once every other remedy has been used.
- The Ministry of Economic Affairs and Employment is responsible for public communications.
- Fingrid is responsible for operational implementation during electricity shortage events in Finland and for coordinating actions with the neighbouring countries.
- The local distribution system operators are responsible for restricting electricity distribution in accordance with the instructions issued by Fingrid’s Main Grid Control Centre.
- The National Emergency Supply Agency will begin to take action if the special emergency restrictions and electricity rationing measures specified in the Emergency Powers Act are introduced. Among other things, the Government may restrict or prohibit the consumption of electricity for all purposes except those that are essential for the security of supply or impose an electricity consumption quota.
- Electricity shortage possible (1): The forecasts indicate that in the near future, Fingrid will be unable to maintain rapid disturbance reserves in an amount that would offset a dimensioning fault and domestic production and imports are not enough to cover electricity consumption. Fingrid will announce this on its website. The Ministry of Economic Affairs and Employment will inform citizens of the possibility of an electricity shortage.
- High risk of electricity shortage (2): All the electricity production available in Finland is in use, and no more electricity can be obtained from Finland’s neighbouring countries. Fingrid will announce this on its website. The Ministry of Economic Affairs and Employment will inform citizens of the possibility of an electricity shortage.
- Electricity shortage (3): Electricity production and imports are not enough to cover consumption, and Fingrid needs to exercise its right as the party responsible for the system to disconnect electricity consumers. Fingrid will announce this on its website. The Ministry of Economic Affairs and Employment will inform citizens of the possibility of an electricity shortage.
An electricity shortage ends when the production and imports of electricity are sufficient to cover consumption. Fingrid, the transmission system operator, will announce the end of an electricity shortage. Electricity shortages may recur, and in such a situation, Fingrid will follow the same electricity shortage instructions again.
INFORMATION FOR CONSUMERS
No. According to the Electricity Market Act, consumers are entitled to a price reduction or damages on the basis of an error in electricity distribution. A power cut necessitated by an electricity shortage is not an example of an error in electricity distribution, so no compensation would be payable on the basis of the liability for errors described above. Similarly, since such an event is beyond the control of the distribution system operator, the standard compensation for electricity distribution outages provided under the Electricity Market Act would not apply.
Fingrid will notify each distribution system operator of how much power must be disconnected. After this, the network operators should implement electricity distribution outages in a rotating fashion.
The restriction is requested to start immediately, and the restriction is announced to remain in force until further notice. The network operator will rotate the load shedding around its distribution network in two-hour outages.
Consumers are advised to prepare themselves for electricity shortages by purchasing household essentials in advance. Consumers should follow the information about saving electricity and the guidelines issued by the authorities. The Ministry of Economic Affairs and Employment is primarily responsible for informing citizens of the possibility of an electricity shortage, but Fingrid, local distribution system operators and the media may also publish information and guidelines about electricity shortages.
Keeping a stock of food and drink at home in case of emergencies is one aspect of contingency planning. The recommendation is for people to have 72 hours of emergency supplies, so every household should be able to cope independently for at least three days in the event of a disturbance. For more information on emergency supplies in the home, see the Martha Organisation’s website.
Load shedding (disconnection) plans have already been made for use in the event of an electricity shortage. These ensure that the most critical electricity consumers – such as hospitals – would not lose power. Hospitals also have their own reserve power generators. Reserve power ensures that hospitals can continue to operate uninterrupted.
In principle, nobody is likely to be liable. No specific laws provide for damages in the event of an electricity shortage; the case would need to be tested in accordance with the statutes and doctrines of general liability law. As an electricity shortage is an exceptional event affecting the functioning of a public market (see the definition above), it may be impossible, in practice, to apportion blame to any individual party.
Planned power cuts are among the last measures taken to address an electricity shortage. Before resorting to this, a series of other measures will be taken, such as requesting additional balancing bids and starting up the reserve power plants intended for dealing with disturbances.
Primarily, Fingrid endeavours to use voluntary measures by electricity producers and consumers in the electricity market. It will only become necessary to begin restricting electricity distribution once all possible measures have been taken on market terms.
In the event of an electricity shortage, the price of electricity is likely to be very high.
An electricity shortage occurs when electricity production and imports are not enough to cover electricity consumption. In such cases, it is necessary to restrict consumption to stop the power system from crashing altogether. Under normal conditions, electricity is needed the most in the morning hours on weekdays, when society is at work. If an electricity shortage occurs, the measures to restrict electricity consumption must target the times when electricity production and imports are not enough to cover electricity consumption.
Under normal conditions, when we look at the power system of Finland from the perspective of the main grid, the answer is simple: there is plenty of electricity – enough for electric vehicles as well. When electricity is cheap, it means there is no shortage of electricity, and electric vehicles are charged at times when electricity is cheap. Smart charging solutions are included in electric vehicle charging stations and in the vehicles themselves, enabling electric vehicles to be charged when electricity is more affordable.
In the future, as technology develops, it may become possible to use electric vehicles to support the main grid. One way of doing this would be for electric vehicles to feed electricity back into the main grid from their batteries.
At the moment, Finland is reliant on imports at times of peak electricity consumption. In other words, the power plants in Finland are not currently able to produce enough electricity to cover the largest estimated consumption peaks.
Electrification is proceeding at pace in Finland. In the coming years, Finland will become mostly self-sufficient in electricity production as the Olkiluoto 3 nuclear power plant ramps up and major wind power investments come online.
In 2021, a total of 86.7 terawatt-hours of electricity was consumed in Finland. The electricity consumption peak of 14,267 MWh/h occurred between 9 am and 10 am on 18 February 2021. Domestic production was then 11,191 MWh/h and net imports were 3,076 MWh/h.
In 2021, Finland’s electricity consumption was approximately seven per cent higher than in the preceding year. The reasons behind this rise were a colder winter and a return to normal volumes of industrial consumption following the uncertainty caused by the coronavirus pandemic in the previous year.
In addition to domestic production, electricity can be imported to Finland from Sweden, Estonia and, in small quantities, Norway. There has been no electricity transmission between Russia and Finland since May 2022.
In 2021, the vast majority of the electricity transmissions between Finland and Russia were imports from Sweden to Finland. In 2021, a total of 15.9 terawatt-hours of electricity was imported from Sweden to Finland, and 0.9 terawatt-hours was exported from Finland to Sweden. The predominant direction of electricity transmission between Finland and Estonia was from Finland to Estonia – a total of 6.7 terawatt-hours. A total of 0.3 terawatt-hours of electricity was imported from Norway to Finland in 2021. A total of 9.2 terawatt-hours of electricity was transmitted from Russia to Finland.
Disconnection plans have already been made for use in the event of an electricity shortage. These ensure that the most critical consumers – such as hospitals – are not disconnected. Efforts will be made to avoid electricity distribution outages affecting consumers for as long as possible, and consumers will only have their power disconnected once every other remedy has been used. It is possible that some critical electricity consumers could be disconnected if the electricity shortage is prolonged or the restriction is large in scope.
Critical parties have their own reserve power generators, which start up if there is no electricity available on the distribution network. Critical parties should test their reserve power generators regularly.
