Description of balance model
The balance service model was revised at the beginning of 2009, when uniform main principles were introduced in the Nordic countries.
Main changes in the balance service model from the former procedure:
- introduction of two balances: production and consumption balance
- binding production plans
- reporting of production plans and regulating bids 45 minutes before the beginning of the specific hour
- change in the cost structure relating to balance service.
Model of two balances
In the model of two balances, generation is handled in one balance, and purchases, sales and consumption of electricity in another. Moreover, the production plan given from the production balance before the beginning of the specific hour is processed in the consumption balance in the balance settlement procedure.
A different price model is applied to the balance deviation existing in the production and consumption balances, i.e. to balance power. A two-price system is applied to the balance deviation in the production balance, and a one-price system is applied to the balance deviation in the consumption balance.
