Europe’s leading battery optimization company Entrix has reached 3 GW / 8.5 GWh of contracted battery storage capacity with final investment decisions across Europe, marking a defining milestone in the company’s evolution into the European leader in flexible energy trading and optimization at scale. Of the contracted portfolio, 2 GW will be live and operational within 2026. Entrix operates a large and growing portfolio of battery storage systems across Europe, with more than 70 systems under management spanning from standalone projects to co-location 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. A consortium of investors has committed an additional 43m€ capital, consisting of BNP Paribas via its Solar Impulse Venture Fund, insurance company Allianz, Belgian energy-focused investors Junction Growth Investors and Korys, 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 over the past years grown into Europe's leading player in battery optimization. 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. This milestone also reflects a structural transformation of the European power system: flexibility is no longer a concept – it has become a decisive success factor for system stability, affordability and renewable integration.
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, which still set marginal power prices across much of the continent, 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 centers, which require uninterrupted, stable power supply at scale. More broadly, battery storage is becoming the backbone of a fossil-free energy system – bridging the gap between intermittent renewable generation and reliable, around-the-clock power supply.
Entrix is a leading player in optimizing battery storage systems across all relevant electricity markets, including balancing services, day-ahead and intraday trading. Its AI-driven trading and optimization 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.
Beyond short-term trading, Entrix structures bankable, investment-grade fixed revenue models across its markets — playing a central role in making flexibility scalable and system-relevant across Europe. Working closely with both financial institutions and long-term offtakers such as Deutsche Bahn Energie helps translate flexibility into stable, financeable revenue streams that unlock the investment needed to accelerate the energy transition.
Backed Europe’s leading energy investors
A consortium of investors has now committed 43m€ in additional capital into Entrix, marking the next step in the company's European growth trajectory and enabling further technological advancements. The consortium includes BNP Paribas via its Solar Impulse Venture Fund, insurance company Allianz, Belgian energy-focused investors Junction Growth Investors and Korys (Colruyt Family Office), AENU, Enpal, Abacon (Büll Family Office) and Arvantis Group.The transaction reflects institutional confidence in Entrix’s scalable business model and supports the continued expansion of its operational capabilities, market reach, and technological leadership.
"The scale of projects entrusted to us 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."
Entrix offers an end-to-end solution in five core markets: Germany, Poland, Italy, Spain and Portugal
Entrix is active across five European markets, each at a different stage of the energy transition. Germany represents Entrix’s largest market by capacity. The company operates one of the country’s first large-scale battery systems and has expanded into co-located models combining renewable generation and storage. Clients include large Independent Power Producers, infrastructure investors and municipal utilities as well as well-known companies such as MEAG (Munich Re) or Encavis.
Poland represents a fast-evolving flexibility market, supported by capacity mechanisms and structural changes in the generation mix. Entrix entered the Polish market with a local presence in Warsaw and strategic partnerships with developers and investors such as Greenvolt (KKR portfolio company). With its first 5 projects in Poland scheduled to go live within the course of this year, Entrix is taking an important step in establishing the company as a long-term partner for investors and developers in this market.
Entrix is also expanding across Italy, applying its proven track record as a first mover and market leader to help unlock grid congestion and rapid renewable expansion. Italy added more than 5 GW of solar capacity in 2024 alone, significantly increasing price volatility and regional grid congestion between the North and the South. At the same time, recent capacity market auctions have confirmed the growing role of flexible assets in ensuring system adequacy. In this environment, battery storage is becoming a structural necessity rather than an optional add-on.
Iberia is one of Europe’s most dynamic renewable power markets. Spain alone has added more than 20 GW of solar capacity in recent years, increasing the need for storage to manage intraday volatility and curtailment risks. The April 2025 Iberian grid blackout also highlighted the critical importance of flexible capacity and advanced balancing services to safeguard grid reliability in an increasingly dynamic system.
With battery storage moving to the center of Europe’s energy architecture, Entrix is positioned to further scale its business model and play a defining role in shaping the next generation of resilient, renewable power markets.
