Imbalance Prices

APG will publish indicative imbalance settlement prices for the APG control area. It is important to note that the published values are based on preliminary data. An update will be provided at a later point in time.

 

Calculation method

Imbalance settlement prices are calculated for negative imbalances as the maximum of the weighted average price for activated positive balancing energy from frequency restoration reserves (automatic frequency restoration reserve (aFRR) and manual frequency restoration reserve (mFRR)), the wholesale market indicator and the scarcity price and for positive imbalances as the minimum of the weighted average price for activated negative balancing energy from frequency restoration reserves (aFRR and mFRR),the wholesale market indicator and the scarcity price.

The weighted average price for activated balancing energy considers all activations for the imbalance area APG.

The weighted average price for activated balancing energy is calculated based on an exported bids model and considers all activations for APG. In the cooperations with Germany, activations of balancing energy in Germany for Austrian demand are relevant for the Austrian imbalance settlement price while activations in Austria for German demand are not relevant for the Austrian imbalance settlement price.

NEMOs provide average prices and volumes which APG will publish for a limited period of time. APG points out that the published NEMO-data is provided for transparency reasons only and a use other than to trance imbalance prices is not permitted.

APG further points out that data provided by EPEX SPOT may only be used for an internal usage. EPEX SPOT remains owner and source of the data. A possible commercial use of the data shall be authorized by EPEX SPOT (General Conditions der EPEX SPOT).

APG further points out that data provided Nord Pool may only be used for an internal usage in order to follow the imbalance prices. Nord Pool pot remains owner and source of the data. Any re-distribution of the data is prohibited.

A description of the values in the table and a description of their use in imbalance price calculation can be found here.


 

Based on updated input data, imbalance settlement prices will be updated. At t+15 min an initial indicative value is published; immediate adjustments or missing values are added in quality "15 min". Better balancing energy prices and better estimated values for total imbalance are expected at t+3 working days and t+6 working days. Those values can be taken into account in the updates of the quality "estimated". Final prices that are used for imbalance settlement are saved in quality "final". In the table view, data at a given timestamp can be shown.
