The battery optimisation company says 2GW of its contracted capacity will be live in 2026, underscoring the growing role of flexibility as critical energy infrastructure across Europe.
Battery optimisation company Entrix today announced two critical milestones. It has raised €43 million in funding and reached 3 GW / 8.5 GWh of contracted battery storage capacity. Of the contracted portfolio, 2 GW will be live and operational during 2026.
Entrix operates a large and growing portfolio of battery storage systems across Europe, with more than 70 systems under management, ranging from standalone projects to co-located solar-plus-battery models.
The company maintains offices and local teams in Germany, Italy, Spain, and Poland, ensuring strong market proximity and regulatory expertise across its core European markets
The funding is led by Junction Growth Investors and Korys, alongside BNP Paribas via its Solar Impulse Venture Fund, Allianz, AENU, Enpal, Abacon, and Arvantis Group. What began in 2021 as a pioneer operating one of Germany’s first large-scale battery storage projects has grown into Europe’s leading player in battery optimisation.
With 3 GW of contracted flexible capacity, Entrix operates at a scale equivalent to approximately three nuclear power plants or the peak electricity demand of around three million households.
Flexibility as critical infrastructure
As renewable penetration accelerates and power markets become increasingly volatile, orchestrating flexibility across markets becomes critical – and increasingly urgent.
Europe’s continued exposure to unstable fossil fuel markets has made accelerating the energy transition not only a climate imperative but a strategic one.
The need for flexibility is further amplified by the rapid growth of data centres.
Entrix offers an end-to-end solution in five core markets: Germany, Poland, Italy, Spain and Portugal. Germany represents Entrix’s largest market by capacity, while Poland represents a fast-evolving flexibility market, supported by capacity mechanisms and structural changes in the generation mix.
Entrix optimises battery storage systems across all relevant electricity markets, including balancing services, day-ahead and intraday trading. Its AI-driven trading and optimisation enables batteries to respond in real time to price signals, grid needs and portfolio strategies – turning technical flexibility into measurable economic value and helping make the energy transition more affordable, greener and more efficient for everyone.
According to Steffen Schülzchen, founder and CEO of Entrix, the scale of projects entrusted to the company reflects a structural shift in the energy system: flexibility has become critical infrastructure.
“Our role is to translate technical performance into stable, risk-adjusted revenues for investors while strengthening grid resilience and enabling renewable integration at scale.
This milestone underscores the long-term partnerships and operational depth we have built across Europe.”
