European battery optimisation leader Entrix has marked a major leap in its growth journey by securing €43 million in fresh funding while simultaneously scaling its contracted battery storage capacity to 3 GW and 8.5 GWh. The milestone reflects not only the company’s rapid expansion but also the rising importance of energy flexibility as Europe accelerates its transition toward renewable power systems.
Funding Backed by Major Institutional Investors
The new funding round was led by Junction Growth Investors and Korys, with participation from BNP Paribas through its Solar Impulse Venture Fund, alongside Allianz, AENU, Enpal, Abacon, and Arvantis Group. This strong consortium highlights increasing investor confidence in infrastructure that supports renewable energy integration.
Founded in 2021, Entrix has quickly evolved from operating one of Germany’s earliest large scale battery storage projects into one of Europe’s most prominent players in battery optimisation.
Rapid Growth in Battery Storage Portfolio
Entrix currently manages more than 70 battery storage systems across Europe, covering a mix of standalone installations and solar plus battery projects. Its contracted portfolio of 3 GW represents a significant scale, with 2 GW expected to be live and operational by 2026.
To put this into perspective, the company’s flexible capacity is comparable to the output of roughly three nuclear power plants or the peak electricity demand of around three million households. This scale underlines the growing role of battery systems in stabilising energy supply as renewable sources expand.
Strong Presence Across Key European Markets
The company has established offices and local teams in Germany, Italy, Spain, and Poland, ensuring close alignment with regional regulations and market dynamics. It also operates in Portugal, offering end to end optimisation solutions across five core markets.
Germany remains its largest market by capacity, while Poland is emerging as a fast evolving hub for flexibility solutions due to supportive policy frameworks and shifts in energy generation.
Flexibility Emerges as Critical Infrastructure
As renewable energy penetration increases, power markets across Europe are becoming more volatile and complex. Entrix is positioning itself at the centre of this transformation by enabling flexibility across energy systems, which is now considered essential infrastructure rather than an optional enhancement.
The urgency of this shift is further intensified by Europe’s exposure to unstable fossil fuel markets and the growing demand for electricity driven by sectors such as data centres. These factors are pushing grid operators and energy providers to adopt smarter, more responsive systems.
AI Driven Optimisation for Energy Markets
Entrix’s core strength lies in its AI driven trading and optimisation platform, which enables battery systems to respond dynamically to market signals and grid requirements. The company operates across multiple electricity markets, including balancing services, day ahead trading, and intraday markets.
By converting technical battery performance into measurable economic value, Entrix helps investors achieve stable, risk adjusted returns while simultaneously improving grid resilience and supporting renewable energy integration.
Leadership Vision on the Energy Transition
Founder and CEO Steffen Schülzchen emphasised that the scale of projects entrusted to the company reflects a broader structural shift in the energy system. According to him, flexibility has become a cornerstone of modern energy infrastructure.
He highlighted Entrix’s role in bridging the gap between technical capability and financial performance, ensuring that battery storage assets deliver both economic and environmental benefits.
Driving Europe’s Clean Energy Future
With fresh capital and a rapidly expanding portfolio, Entrix is well positioned to play a central role in Europe’s energy transition. Its ability to optimise battery systems at scale addresses one of the most pressing challenges in renewable energy adoption, balancing supply and demand in real time.
As the continent moves toward a cleaner and more resilient energy system, Entrix’s infrastructure and technology are set to become increasingly indispensable, enabling a future where renewable energy is not only sustainable but also reliable and economically viable.
