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.
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)) and the wholesale market indicator, and for positive imbalances as the minimum of the weighted average price for activated negative balancing energy from frequency restoration reserves (automatic frequency restoration reserve (aFRR) and manual frequency restoration reserve (mFRR) and the wholesale market indicator.
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.
The wholesale market indicator is calculated based on the intraday price ID3, taking into account a weighted day-ahead price (market coupling price of EPEX SPOT) in hours when intraday market liquidity does not exceed a defined threshold.
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.
A description of the values in the table and a description of their use in imbalance price calculation can be found here.
According to the Terms and Conditions for BRPs, as they have also been approved by E-Control, all costs of energy components, i.e. costs of aFRR activation, mFRR activation, imbalance netting processes, unintended exchange of energy, and possible penalties and non-remuneration are allocated to the income from imbalance settlement with the BRPs.
In the new imbalance settlement regime, a financial surplus or shortage can occur each month. Article 44 (2) EBGL establishes the responsibility of the regulator to ensure financial neutrality of the TSO. Financial results shall be passed on to network users in accordance with the applicable national rules. As currently there are no existing applicable national rules, the financial results are held at APG until national rules are established by Austrian national law.
