Fuse Energy Raises €70 Million to Scale Flexible Clean Power Across Europe

European energy startup Fuse Energy has raised €70 million in a funding round led by Balderton Capital, with participation from Lowercarbon Capital. The investment reflects growing investor confidence in new business models designed to stabilise power systems while accelerating the shift away from fossil fuels.

Founded in the United Kingdom, Fuse Energy is positioning itself as a next-generation energy company focused on flexible, low-carbon electricity. Rather than operating solely as a power supplier, the company integrates generation, storage, and data-driven optimisation to respond to fluctuations in energy demand and supply. This approach is increasingly relevant as European grids absorb higher shares of intermittent renewable energy such as wind and solar.

According to Fuse Energy, the new capital will be used to expand operations across additional European markets, increase investment in renewable generation assets, and further develop its proprietary software platform. The platform is designed to forecast electricity demand, manage price volatility, and optimise the dispatch of clean energy in real time.

Addressing Volatility in European Power Markets

Europe’s electricity markets have experienced sustained volatility in recent years, driven by geopolitical shocks, high gas prices, and the rapid deployment of renewables. While wind and solar have reduced emissions and wholesale prices at times, their variability has also increased the need for flexibility solutions such as battery storage, demand response, and smarter grid management.

Fuse Energy’s model aims to address this gap. By combining renewable generation with flexible assets and advanced analytics, the company seeks to supply power when it is needed most, while avoiding reliance on fossil fuel peaker plants. This is particularly relevant during periods of low renewable output or peak demand, when electricity prices can spike sharply.

The company works directly with industrial and commercial customers that have high energy consumption and exposure to price fluctuations. By offering tailored power contracts and flexibility services, Fuse Energy claims it can help customers reduce energy costs while lowering their carbon footprint.

Investors Focus on Execution, Not Just Ambition

The funding round highlights a broader shift in climate and energy investment. After several years of rapid capital deployment into clean technology, investors are increasingly prioritising companies that demonstrate operational execution and clear revenue models.

Balderton Capital has stated that Europe’s energy transition requires companies capable of operating within complex, regulated markets while scaling infrastructure quickly. Lowercarbon Capital, which focuses on technologies with direct emissions reduction potential, has emphasised the importance of grid flexibility in achieving net-zero targets.

Energy system experts widely agree that flexibility will be one of the defining challenges of the next phase of decarbonisation. As coal and gas plants retire, grids must rely on a combination of storage, digital optimization, and demand side participation to maintain reliability.

Scaling Across Fragmented Markets

One of the key challenges for Fuse Energy will be expansion across Europe’s fragmented energy landscape. Electricity markets, grid rules, and regulatory frameworks vary significantly between countries, complicating cross-border scaling.

However, this fragmentation also creates opportunities. Many European countries are accelerating renewable deployment faster than grid upgrades, increasing the value of flexible energy providers. Markets with high shares of wind and solar, such as the UK, Spain, and parts of Northern Europe, are particularly exposed to imbalance risks.

Fuse Energy has indicated that part of the new funding will be allocated to building local teams and regulatory expertise to support market entry. The company is also exploring partnerships with renewable developers and storage providers to secure long-term access to clean power assets.

Implications for the Net-Zero Transition

The success or failure of companies like Fuse Energy has implications beyond individual investors or customers. Grid flexibility is now widely recognised as a prerequisite for achieving climate targets while maintaining energy security and affordability.

If scalable, Fuse Energy’s integrated model could reduce the need for fossil fuel backup capacity, lower system costs, and improve the utilization of renewable energy. For policymakers, this reinforces the importance of market designs that reward flexibility and real-time responsiveness.

For corporate energy buyers, the emergence of flexible suppliers offers an alternative to traditional fixed price power purchase agreements, which may not fully capture the risks and opportunities of volatile markets.

While challenges remain, including regulatory complexity and capital intensity, the €70 million raise suggests that investors see Fuse Energy as a credible player in Europe’s evolving energy system. As renewable penetration increases, solutions that bridge the gap between clean generation and reliable supply are likely to play an increasingly central role.
