The Missing Layer of Power Markets: Battery Optimization with Steffen Schülzchen of Entrix

Welcome back to The Pexapark Podcast!In the first part of the episode, Luca Pedretti speaks with Steffen Schülzchen, CEO and Founder of Entrix, about the rise of battery optimization and the role of software in turning flexibility into a scalable business. Entrix is one of Europe’s leading battery optimizers in the flexibility space, helping large-scale batteries operate across power markets, ancillary services, and evolving offtake structures.Key themes from the discussion:What a battery optimizer actually does – beyond simply “trading” batteries How Entrix uses software and automation to optimize BESS across multiple revenue streams Why battery performance depends on market forecasts, asset constraints, warranties, and state of charge How optimization agreements, merchant exposure, and longer-term offtake structures are evolving Why European expansion requires local market knowledge, even with a scalable tech platform How the optimizer market may develop across Europe as flexibility becomes critical infrastructure In the second part of the episode, Luca turns to recent Pexapark market intelligence. He examines the role of demand-side flexibility in Europe’s changing power system, and why it looks compelling on paper but remains difficult to scale in practice. While industrial demand response can compete with BESS in some balancing and capacity markets, its availability depends on operational constraints and market design. The takeaway: demand-side flexibility has a role to play, but for now, BESS remains the more controllable, scalable force shaping intraday spreads in Europe.Unlock More PPA Market InsightsRegister for your free Pexapark account to stay updated on the latest energy transition trends.
