Oldenburg, Germany / Athens, Greece – Optimus Energy, a leading direct marketer in the field of renewable energy and provider of demand-response services in Greece, has commissioned the German technology provider Emsys VPP to supply its Virtual Power Plant (VPP).

The goal of the collaboration is the efficient marketing of Optimus Energy’s almost 4,000 MW (4 GW) solar and wind energy portfolio in the Greek wholesale electricity and balancing market.

Emsys VPP has begun implementing the Virtual Power Plant and is adapting the software specifically to the needs of Optimus Energy.

Energy & Meteo Systems, a partner company of Emsys VPP, provides precise solar and wind performance forecasts for the plants integrated into the Virtual Power Plant on behalf of Optimus Energy.

Additionally, emsys VPP is supplying a tailored Virtual Power Plant for providing balancing energy services. This opens up additional revenue opportunities for Optimus Energy while also contributing to grid stability through increased operational flexibility.
