On the 5th of October 2022, the Pan-European platform for the exchange of manual Frequency Restoration Reserves (mFRR) balancing energy has been brought successfully into operation. CEPS and the German TSOs (TenneT DE, 50Hertz, Amprion, and TransnetBW) have accessed the platform and cross-border exchanges were successfully performed.
Artelys is proud to have developed the market clearing engine at the core of this balancing market. After successful delivery of the market clearing engine for the exchange of replacement reserves (TERRE project), Artelys was tasked to specify and implement the activation optimization function for the MARI project.
This optimization function, the Libra Optimization Module, selects the best combinations of demands and bids in order to balance the electricity grid and meet system adequacy while taking into account both business and technical constraints (e.g., related to the power grid). The optimization function meets high-performance and high-availability requirements. It can be called every 30 seconds and shall return results within 15 to 60 seconds (depending on the clearing mode) while accounting for complex bids, coupled markets, network constraints, and pricing rules.

About mFRR and MARI project:
MARI (Manually Activated Reserves Initiative) is the European implementation project for the creation of the Pan-European platform for the exchange of balancing energy from frequency restoration reserves with manual activation between the member states of the European Union. MARI project includes 29 TSO members and 4 TSO observers along with the European Network of Transmission System Operators for Electricity (ENTSO-E).
Manual Frequency Restoration Reserves (mFRR) refer to the active power reserves that are available to TSOs to restore the system frequency to its nominal value and to restore power balance to the scheduled value and thus compensating the activated FCR power. mFRR are used when there are longer lasting deviations in the power grid that cannot be resolved solely by the other upstream balancing services (Frequency Containment Reserves (FCR) or automatic Frequency Restoration Reserve (aFRR)).
