The European Project for Long term Real-time balancing Electricity market design (EXPLORE) is a joint venture by five TSC members: APG, the Austrian transmission system operator (TSO), the Dutch-German TSO TenneT, and the German TSOs 50Hertz, Amprion, and TransnetBW. In cooperation with the Belgian TSO Elia, the partners have been evaluating since 2015 possibilities of integrating their respective markets for frequency restoration reserves (FRR) in view of the future requirements of the Guideline on Electricity Balancing by the European Commission.
In October 2016, the TSOs published a report on a target model for the exchange of FRR and asked stakeholders for feedback. Their comments and suggestions, as well as the TSO responses and further investigations, have now been incorporated into an addendum to the target model report.
Since two new FRR projects have been initiated this year, the EXPLORE activities are being continued within the scope of these two new projects. MARI (Manually Activated Reserves Initiative) for research on frequency restoration reserve with manual activation (mFRR) was launched in April, and PICASSO (Platform for the International Coordination of the Automatic frequency restoration process and Stable System Operation) for exploring the integration of automatic frequency restoration reserves (aFRR) followed in August.
