Optimus Energy and enspired join forces to unlock battery storage potential in Greece
ATHENS, May 6, 2025 — A major step forward for Greece’s energy transition: Optimus Energy, the country’s leading aggregator for renewables and flexible load, has partnered with enspired, Europe’s top specialist in energy storage optimization. Together, they aim to bring advanced battery optimization services to Greece’s grid, starting with a 270 MW portfolio of battery energy storage systems (BESS), covering both merchant and subsidized projects.
A critical moment for solar-rich, storage-poor Greece
Greece currently enjoys a surplus of solar power—but no operational battery systems to balance the grid. The result? High volatility, routine curtailments, and wasted clean energy. With 14 GW of renewables installed and 26 GW expected by 2030, storage integration is now urgent.
“We’re seeing extreme curtailments at midday and during low-demand periods,” said Stella Zacharia, CEO of Optimus Energy. “To absorb the coming wave of renewables, Greece will need 4 to 5 GW of storage. Today, we don’t even have 1 MW. That’s why we’re partnering with enspired—to launch a full-service optimization model from day one.”
With enspired’s technology, Optimus Energy will provide Greece’s first comprehensive BESS optimization service—a turnkey solution that combines trading expertise, AI-driven algorithms, and local market insight.
Optimization as a service
Through this alliance, Optimus Energy becomes the exclusive route-to-market provider for BESS in Greece, while enspired delivers real-time algorithmic trading and strategy execution. Customers gain access to advanced forecasting, dynamic flexibility allocation, and tailored market participation.
Among the first clients are assets owned by companies within the GEK TERNA Group, including a 150 MW fully merchant BESS developed by Optimus’ parent company, HERON ENERGY S.A.
“Our goal is to build battery assets that are grid-reliable and commercially viable from day one,” said Loukas Dimitriou, CEO of HERON.
AI-powered, market-ready battery trading
enspired’s proprietary trading platform, built for pan-European deployment, uses billions of data points alongside AI and reinforcement learning to drive optimal performance. It supports operations across wholesale and ancillary service markets, including FCR and aFRR/mFRR.
“Optimus Energy’s market insight paired with our technology creates a uniquely strong entry into Greece,” said Wolfgang Eichberger, Chief Innovation Officer at enspired. “Our platform delivers maximum revenue potential—even in new markets.”
The platform also offers full transparency through a 24/7 live trading dashboard and third-party-certified portfolio performance data. Flexible commercial models are available to suit a range of customer needs.
A milestone for Greece’s energy future
This partnership marks a turning point for Greece’s energy market.
“We see this as a natural next step in our mission to modernize energy in Greece,” said Costas Baslis, Chairman of Optimus Energy. “With enspired, we’re offering a vital service to support the country’s renewable expansion and energy security.”
Jürgen Mayerhofer, CEO of enspired, added: “With over 3 GW of storage projects in the pipeline, Greece is a new frontier for innovation. Our collaboration gives us an early foothold, representing nearly 10% of the upcoming market. We’re proud to partner with Optimus Energy to bring this vision to life.”
