At the recent event “The Future of Power Markets in Greece and Southeast Europe”, organized by the Greek Energy Forum, Dr. Dimitrios I. Chatzigiannis, Consultant at Optimus Energy S.A., joined an engaging panel discussion that brought together market leaders, experts, and professionals from across the energy sector. His insights offered a deep dive into three core areas defining the next phase of the energy transition: the dynamics of real-time market participation, the optimization of flexibility solutions, and the operational backbone behind transparent and efficient trading.
Dr. Chatzigiannis highlighted that while renewables in Greece have traditionally relied on Day-Ahead Market Clearing Prices, the rise of Battery Energy Storage Systems (BESS) opens the door to thousands of trading opportunities per day. With markets such as Intraday Auctions and Continuous Trading introducing highly dynamic price signals, successful operation now demands real-time responsiveness rather than static scheduling. He explained that smart optimizers, like Optimus Energy’s partner, enspired, continuously re-evaluate market data and forecasts to decide when, where, and how much energy to commit, maximizing value while minimizing risk. This paradigm shift transforms energy storage into an active, revenue-generating market participant.
Focusing on the technical and operational foundation of energy management, Dr. Chatzigiannis presented how Optimus Energy’s Virtual Power Plant (VPP) framework integrates real-time data to deliver precise dispatch decisions, while Optimus Energy ensures compliance, commercial settlement, and seamless integration with trading platforms that the company is active in such as HEnEx and IPTO. This approach enables assets to unlock their full economic potential across all timeframes while maintaining security, control, and regulatory alignment.
In concluding his remarks, Dr. Chatzigiannis expanded on a concept often misunderstood in energy trading: that market access is not limited to simple “bidding”. Using the “iceberg” analogy, he illustrated that the end act of bidding represents only a fraction of the daily operations behind energy management. True market access, as Optimus Energy practices it, encompasses a wide range of functions, from advanced forecasting techniques to accurately predict renewable production, demand, and price dynamics, to continuous portfolio monitoring, imbalance cost management, flexibility dispatch, and real-time IT integration with SCADA and API platforms. Behind the scenes, continuous communication with grid operators, regulatory compliance, metering data management, and the use of hedging instruments such as PPAs complete the operational framework. As Dr. Chatzigiannis emphasized, only by mastering these interdependent layers can a route-to-market provider achieve sustained market performance and provide real value to its clients and contribute to grid stability.
Optimus Energy is a frontrunner in Greece’s evolving energy landscape, combining technical innovation, market expertise, and transparent operations to bridge the gap between renewable generation, flexibility solutions, and modern trading environments. The company remains committed to supporting Greece’s energy transition through cutting-edge optimization solutions, smart grid integration, and partnerships that bring international best practices to the Greek market.
