ESTONIAN ROOTS, GLOBAL IMPACT

Your partner in simplifying energy flexibility

Energy markets don’t work the same way in Estonia as they do in Bulgaria, Romania, Finland or Greece. That complexity is exactly what we built Fusebox OS to solve. We provide one operating layer that normalizes asset management and market access, wherever your portfolio sits. Today, we have customers in 13 markets – all driven from our operational hub in Tallinn.

Bridging the gap to a greener grid

A sustainable future depends on how we manage distributed resources. We build the digital backbone that turns fragmented energy assets into high-performing Virtual Power Plants. By orchestrating real-time flexibility, we make renewable energy reliable and ensure that every kilowatt produced is used where it’s needed most.

WHY LEADERS CHOOSE FUSEBOX

Modern energy operations are fragmented across controllers, EMS, forecasting, trading systems, and TSO interfaces. This fragmentation slows scaling, increases operational risk, and turns every new market or asset type into a new integration project.
