A special phenomenon: Those who produce electricity have to pay for the production. Those who consume receive money for consumption.

For the first time in Finland, the situation in the electricity wholesale market is such that the price of electricity is negative.

This phenomenon has occurred in Denmark and Germany. It will be seen for the first time in Finland next night.

"It means that the market is turning around a bit," says Ville Karttunen, director of new services for the electricity company Caruna.

- Those who produce electricity in Finland have to pay for producing electricity. Those who consume electricity, in turn, get money for the good of consuming electricity.

Karttunen says that the negative price of electricity is a phenomenon unique in Finland.

The phenomenon is due to natural conditions and overproduction. By next night there will be a storm, which will lead to a lot of wind power production in Finland.

- At the same time as the weekend night, consumption is low. In addition, the paper industry is still on strike. They reduce consumption. The weather is so warm too, no household is consuming.

Has high production and low consumption. The price will then turn upside down, according to Karttunen.

Overproduction in Finland is affected by the fact that new wind turbines have been built in Finland. Production of wind turbines is starting to be reflected in the price of stock exchange electricity.

In the background is the Nordic power exchange, Nordpool. In the exchange, big producers and big consumers trade in electricity.

Unlike many other products, electricity cannot be stored. Any electricity that is produced must be consumed somewhere.

Nuclear power stations, wind turbines and other electricity producers now produce too much electricity on the stock exchange.

- Now we are looking for everyone who can adjust their own production down, it is worthwhile to reduce their own production.

Nuclear power plants and wind turbines are such that they cannot adjust their production.

- They now have to produce energy at a fine price.

Karttunen estimates that virtually no one's economy is affected by negative electricity.

According to Karttunen, the negative price of electricity is very small, with a maximum of 20 sets per megawatt-hour. The Loviisa nuclear power plant with a capacity of 800 megawatts will cost 160 euros per hour.

Karttunen estimates that the average consumer does not yet benefit directly from the negative price of electricity.

- If the price goes negative, I understand that the consumer will not pay for electricity, but electricity will be zero-priced.

Instead, large industrial plants that purchase electricity directly from the stock exchange receive electricity at a negative price, ie they are paid back.

Karttunen believes that if this phenomenon becomes more widespread, it will start to be reflected in consumer electricity prices.
