A Pilot Microgrid in the Mega Evydrio Community – Technical and Economic Evaluation

PART OF PEGASUS PROJECT

This report documents the technical and economical evaluation of the Greek pilot microgrid tested in the PEGASUS project, under different operating modes.

The Greek pilot microgrid is planned to be installed near the city of Farsala – in the Mega Evydrio community – and it is going to have one single point of common coupling (PCC) with the main electricity grid. It is going to be organized as a local “energy community”, where the municipality of Farsala and the residents of the community of Mega Evydrio are going to participate.

The present situation for the Greek pilot before the establishment of the micro-grid is the following:

  • The consumers buy electricity from the main grid;
  • The producers sell electricity to the main grid;
  • The prosumers buy electricity from the main grid in a net metering basis (consumption – production). If production is higher than consumption they don’t earn money for the surplus of electricity.

The situation after the establishment of the micro-grid for the Greek pilot will be the following:

  • An “Energy Community” will operate the micro-grid. In the “Energy Community” will participate the local municipality, local residents, local shop owners, local electricity producers, and various other interested parties.

The economic evaluation has taken into account multiple parameters (including resources potential, cost of used renewable sources, the price of purchase for the electricity produced by these sources etc.), studied different scenarios and examined several different strategies for the Mega Evydrio microgrid functioning.
