The Action was part of the Project of Common Interest (PCI) 4.9. "Various aspects of the integration of the Baltic States’ electricity network into the continental European Network, including their synchronous operation".

The Study which determined if the Baltic States power system is capable of operating in isolated mode was carried out under the Action. It covered:
a) Data collection, description of scenarios, creation of common model
b) Steady state and transient stability analysis
c) Set up of the technical requirements and
d) Final report and stakeholder communication in the form of a press release and stakeholder workshop

The deliverable was the Final study report covering the analysis of continental Europe's or the Nordic Network for synchronous zone requirements for island operation, including guidelines and a timeline for performing the Test. The study provided the basis on which to prepare for the Test; the Test itself, however, was not within the Action's scope.
