Two-price and one-price system

In the two-price system, separate prices are calculated for the purchase and sales of imbalance power.

Sales price of imbalance power: The price of imbalance power in the production balance sold by Fingrid to the balance responsible party is the up-regulating price of the hour. If no up-regulation has been carried out or if the hour has been defined as a down-regulating hour, the Finnish day ahead price is used as the sales price of imbalance power in the production balance.

Purchase price of imbalance power: The price of imbalance power in the production balance purchased by Fingrid from the balance responsible party is the down-regulating price of the hour. If no down-regulation has been carried out or if the hour has been defined as an up-regulating hour, the Finnish day ahead price is used as the purchase price of imbalance power in the production balance.

In the one-price system, the purchase and sales prices of imbalance power are identical.

During an up-regulating hour, the price of imbalance power is the up-regulating price, and during a down-regulating hour, the price of imbalance power is the down-regulating price. If no regulations have been carried out during an hour, the price of imbalance power is the Finnish day ahead price.

The table below describes the various price systems.
