Energy flexibility knows no borders, and Fusebox is proud to lead the way with active clients in 13 countries. From utilities and energy retailers to asset owners, we don’t just optimize or trade on the ancillary market—we provide a complete toolkit, including white-label solutions, that clients can use to grow their flexibility business the way they see fit. In this blog, we’ll look at Fusebox’s journey and how our founder, Tarvo Õng, helped shape the company into what it is today.

Our Journey: From Demand Response to a Pan-European Presence

Fusebox’s journey began a decade ago in demand response, where we mastered the integration and management of a wide range of flexible devices, including pumps, compressors, HVAC systems, batteries, crushers, and floor heating. Over the years, we’ve standardized connections for nearly 100 different asset types, ensuring our solutions are safe, functional, and scalable. This expertise forms the backbone of our platform and drives its success in diverse markets.

As our founder and CEO, Tarvo Õng, explains:
“With our strong foundations in asset aggregation and management, it made perfect sense to build advanced software on top of that. Our Virtual Power Plant (VPP) takes asset management to the next level by centrally monitoring and controlling whole portfolios and trading them on ancillary markets. On a local scale, our Energy Management System (EMS) helps solve even more complex challenges, like managing Distributed Energy Resources. These tools allow us to go beyond demand response and tackle the modern energy problems our clients face every day.”

In just two years since launching our VPP software, Fusebox has expanded to 13 countries. Tarvo sums it up: “Our growth shows that we’re solving real problems. Clients trust us to help them access ancillary markets with solutions that fit their unique needs.”

Success Stories That Build Confidence

Fusebox’s solutions have delivered real results for clients across Europe and beyond. One of our newest clients in Mexico used our EMS to optimize solar panels and batteries. By automating charging during low-cost hours and using stored energy during peak demand, they reduced energy bills by 25% and gained energy independence.

In the Nordics, a utility struggling with a diverse asset portfolio turned to our VPP platform. It helped them streamline operations and access ancillary markets like mFRR and aFRR, significantly boosting their revenue. In Greece, another utility built a demand response portfolio with Fusebox, expanding services to small and medium businesses while supporting the country’s transition to renewable energy.

In Northern Europe, a client used our VPP to optimize energy use, improve grid stability, and reduce inefficiencies, leading to substantial savings for their customers. These examples highlight how Fusebox turns energy challenges into opportunities for growth.

What This Means for You

Fusebox’s presence in 13 markets isn’t just about growth—it’s a powerful advantage for our clients. By working in some of Europe’s most advanced flexibility markets, we’ve gained invaluable expertise that helps companies in developing markets prepare for opportunities before they even open.

When it comes to choosing an EMS or VPP solution, energy companies often face three options: building their own software, working with a local provider, or partnering with an international company like Fusebox. As Tarvo explains:
“Building your own software might seem appealing, but it requires immense time and resources. It’s taken us 10 years and over 6 million euros to get here. Local providers can offer localized support, but they often lack the experience to compete in advanced or diverse markets. We come from one of the most advanced markets, the Nordics, and that expertise is already built into our solutions.”

Some international providers impose rigid systems that force companies to overhaul operations. Fusebox takes a different approach. Our modular platform allows clients to choose only the solutions they need and integrates seamlessly with existing systems, enhancing them without disruption. Tarvo adds: “It’s about helping companies move forward without losing what already works.”

Whether you’re looking to optimize energy use, expand into ancillary markets, or future-proof your systems, Fusebox offers the expertise and flexibility to meet your needs.
