Optimus Energy Launches emsys VPP-powered Virtual Power Plant to Trade Renewable Energy in Greece

OLDENBURG, LOWER SAXONY, GERMANY, April 9, 2025 /EINPresswire.com/ -- Optimus Energy has contracted the German service provider emsys VPP to supply its Virtual Power Plant (VPP) for trading renewable energy in Greece’s wholesale electricity and balancing market. With a portfolio of nearly 4 GW of solar and wind power, Optimus Energy holds a leading market position in Greece, representing 50 % of the renewable energy capacity traded under the Feed-in Premium (FiP) scheme or through direct merchant participation, nationally . The collaboration enables Optimus Energy to leverage a proven Software-as-a-Service (SaaS) solution, widely used by aggregators and utilities across Europe, to maximize the value of their renewable energy portfolios in short-term energy markets.

emsys VPP has already commenced setting up its Virtual Power Plant for the wholesale electricity market and is customizing the software to meet Optimus Energy’s specific requirements. This process includes connecting over 3,500 solar and wind power plants to the VPP, enabling real-time data retrieval and dynamic control of variable electricity production. Contracted by Optimus Energy, emsys VPP’s partner company, energy & meteo systems, provides accurate solar and wind power forecasts for the connected assets, which will be integrated into the VPP. This complete software suite allows Optimus Energy to efficiently manage its portfolio including reduction of power generation during periods of negative electricity prices.

Additionally, emsys VPP is supplying a tailored Virtual Power Plant for providing balancing energy services, a strategic expansion of Optimus Energy’s services in the evolving Greek energy market, driven by the constantly increasing penetration of renewable energy sources (RES). Balancing services will benefit both the renewable assets, by creating an additional revenue stream, and the grid, by delivering greater flexibility in line with energy transition objectives. As part of the service, emsys VPP will enable the qualification of renewable assets for participation in the balancing services market. This qualification process includes remote-control tests to ensure that renewable plants connected to the VPP comply immediately with dispatch instructions from IPTO, the Greek transmission system operator.

“Our collaboration with emsys VPP leverages their industry-leading software solutions and extensive international expertise, which are instrumental in optimizing the market potential of our RES portfolio,” says Stella Zacharia, CEO of Optimus Energy. “We’re excited to play a pivotal role in enhancing power system stability in Greece, while also accessing the emerging ancillary services market as a valuable additional revenue stream for our expanding renewable energy portfolio.”

“Our Virtual Power Plant and power forecasts already support several Greek partners in managing their renewable energy portfolios. Providing our Virtual Power Plant for the wholesale and ancillary services market to Optimus Energy marks a significant milestone in bolstering our market presence,” says Dr. Ulrich Focken, Managing Director of emsys VPP and energy & meteo systems.
