Fusebox

The solution

Fusebox is an Estonian energy technology company transforming energy asset management through its Virtual Power Plant (VPP) and Energy Management System (EMS) solutions. The platform connects and manages distributed energy resources, including batteries, renewables, and industrial assets, enabling efficient participation in energy and ancillary markets.

Fusebox’s solution helps clients integrate behind-the-meter assets from 1 kW to 5 MW and beyond, using dedicated controllers for real-time monitoring, centralised management, energy arbitrage, and grid compliance. This enables clients to lower costs, increase revenues, reduce portfolio imbalances, and support the renewable energy transition.

The uniqueness

Fusebox’s competitive edge lies in its highly adaptable and innovative VPP and EMS platform, which seamlessly integrates renewable sources, batteries, and IoT devices across diverse asset sizes—from 1 kW IoT devices to 5 MW systems. This flexibility allows Fusebox to cater to small-scale assets, such as behind-the-meter batteries, and large-scale grid-connected renewable systems, making it a technology-agnostic solution.

Fusebox’s proven market integration experience—operating in eight countries and collaborating with multiple Transmission System Operators (TSOs)—reinforces its scalability and reliability. The platform’s advanced automation and data-driven optimisation deliver unparalleled efficiency. It offers asset owners the ability to reduce losses, avoid penalties and participate effectively in day-ahead, intraday, and balancing markets. By enabling global, hardware-agnostic and country-agnostic deployments, Fusebox empowers businesses to navigate through complex energy markets, reduce their carbon footprints and play an active role in the renewable energy transition.

The challenges

The energy industry faces critical challenges as renewable energy sources such as wind and solar, projected to make up 85% of global electricity production by 2050, introduce significant grid instability due to their intermittent nature. This unpredictability costs energy markets billions of Euros annually, with forecast inaccuracies alone contributing to 40% of financial losses per MW.

Despite the rapid deployment of distributed energy resources (DERs), less than 30% of their capacity is utilised in EU balancing markets, leaving untapped revenue potential which is projected to reach over €17 billion annually by 2030. Battery energy storage systems (BESS), while promising, require real-time control and correct integration to grid to avoid penalties and maximise revenue opportunities such as ancillary market earnings of up to €220,000 per MW per year.

The purpose

Fusebox is committed to driving the global shift to sustainable and independent energy by unlocking the potential of distributed energy resources (DERs). With a platform that leverages already over 3,600 assets, including batteries, commercial & industrial systems, and renewable energy sources, Fusebox delivers innovative solutions for reducing CO2 emissions and enhancing grid stability.

Operating across 13 countries globally and connected to eight Transmission System Operators (TSOs), Fusebox empowers energy companies to manage their own and their customers’ energy assets through an integrated Virtual Power Plant (VPP) with a built-in Energy Management System (EMS). This setup enables localized hybrid system control and active participation in ancillary services like mFRR, aFRR, and FCR, helping clients generate substantial revenue streams, reduce portfolio imbalances, and enhance grid resilience.

The profit

Fusebox operates in the rapidly growing energy management and VPP markets, which are central to the global energy transition. The platform currently manages over 3,600 connected assets, targeting batteries, renewable energy systems and IoT devices, with an Annual Recurring Revenue (ARR) growth trajectory reaching 230% year-over-year (06/2023-06/2024). The company’s total connected capacity is on track to reach 7 GW, reflecting its rapid scaling and market adoption.

The global Virtual Power Plant (VPP) market was valued at $1.5 billion in 2023 and is expected to grow at a compound annual growth rate (CAGR) of 22% from 2024 to 2030 (Source). Additionally, the global battery energy storage market is projected to reach between $120 billion and $150 billion by 2030, more than doubling its size (Source). Fusebox’s revenue streams—SaaS fees and ancillary market participation—position the company to capture these growth opportunities while delivering value to clients through energy cost reductions and improved asset profitability.
