PICASSO (Platform for the International Coordination of Automated Frequency Restoration and Stable System Operation) has enabled cross-border activation of aFRR between Germany and Austria since 2022. The cooperation has grown significantly since then and will cover a large part of the European countries in the future.
As a counterpart to PICASSO, MARI (Manually Activated Reserves Initiative) has enabled cross-border activation of mFRR since 2022. This cooperation is enabling an international exchange of mFRR in Europe.
