Example of balance calculation

Example of balance calculation. The example concerns a balance responsible party whose total production plan for a specific hour is 55 MWh, actual production 60 MWh, actual consumption (load) -40 MWh, and sales to day ahead market -30 MWh.

Composition of balances

Production balance

  • actual production total 60 MWh
  • total production plan -55 MWh

 

The balance deviation in the production balance is a surplus of 5 MWh, which is purchased by Fingrid from the balance responsible party at the purchase price of imbalance power.

Consumption balance

  • total production plan 55 MWh
  • sales to day ahead market -30 MWh
  • actual consumption total -40 MWh

 

The balance deviation in the consumption balance is a deficit of -15 MWh. In order to cover this, Fingrid will sell balance power to the balance responsible party at the sales price of imbalance power, with the volume fee for balance power added to the price.

Prices of imbalance power

The purchase and sales prices of imbalance power are determined as shown in the table below.
