Fusebox is a modular, hardware-agnostic energy operating system that connects assets, tools, and markets into one operating layer you control. It replaces fragmented site control, portfolio tooling, and TSO workflows with a single system, so teams can onboard faster, standardize dispatch, and scale market participation across countries without rebuilding their stack. What we enable (end-to-end): • Control: consistent telemetry + real-time dispatch across mixed fleets • Aggregation: portfolio orchestration with availability, constraints, buffers, and activation logic • Market execution: standardized, TSO-grade workflows from bidding → activation → reporting • Interoperability: open interfaces to integrate partners and keep your existing tools What you keep (you stay in control of): • Your trading desk and market strategy • Your optimizer/forecasting approach (existing or new) • Your commercial model and customer relationships • Freedom to swap tools without re-platforming What Fusebox standardizes (so you can scale): • Asset connectivity patterns and operational data flow • Real-time site control + dispatch coordination • Portfolio availability/constraints and activation logic • Settlement-ready operational outputs and reporting workflows Proven in live operations: Live in 14 European countries with 9 TSO integrations, supporting mFRR / aFRR / FCR workflows. Single deployments manage 1,000+ assets and 300+ MW. Built on 11+ years in flexibility operations. Who it’s for: BRPs, BSPs, utilities, traders, and aggregators managing PV, wind, BESS, and flexible loads. Especially teams who want enabling infrastructure they control, not a dependency.
