Entrix, a Munich-based provider of AI-powered flexibility trading and optimization for battery storage systems, has raised €43 million ($49.5 million) in funding from a consortium of investors including BNP Paribas Solar Impulse Venture Fund and Junction Growth Investors. The platform maximizes revenues for battery owners through multi-market trading and full-service support from development to 24/7 operations. The capital will fuel European expansion, particularly in Iberian markets, and support scaling its 3 GW / 8.5 GWh portfolio under management.
Battery Optimization Investments Surge
The raise aligns with heightened investor interest in Europe's battery sector. Sympower raised €19M in September 2025 for central and southern Europe expansion, while Capalo AI secured €11M in February 2026 for VPP and battery optimization. Entrix's full-service model, including revenue security tools like FloorPlus, positions it to capture value in fragmented flexibility markets across Germany, Poland, Italy, Spain, and Portugal.
Renewables Drive Grid Flexibility Demand
Europe's rapid renewables growth strains grids, with battery storage deployments reaching 61 GWh cumulatively by 2024 and growing 15% annually per SolarPower Europe. Battery owners face volatile prices and grid constraints that limit revenues without advanced optimization. Current solutions often focus solely on trading, leaving gaps in operations and revenue stacking.
AI Trading Maximizes Multi-Market Revenues
Entrix deploys AI for real-time optimization across day-ahead, intraday, and ancillary services like FCR and aFRR. Add-on modules secure revenues through merchant, tolling, and FloorPlus models, while services cover asset development, onboarding, and 24/7 monitoring. This end-to-end approach differentiates from trading-only competitors, enabling grid-neutral operations that support stability while boosting economics.
Full-Service Unlocks Battery Potential
Partnerships with Encavis, MEAG, Aquila Clean Energy, and MW Storage underscore traction, with over 38 projects and 30,000 daily trades. Recent wins include a 12 MW project with Blue Elephant Energy and marketing Enni’s 40 MWh system. The platform's grid-supportive features address congestion, as seen in new Spanish flexible permits.
As an investor noted:
"This fund is helping to unlock huge amounts of new renewable energy across Europe, turbocharging the journey to greater energy security."
Strategic Backers Signal Scale-Up
The syndicate, including Allianz and BNP Paribas, brings sector expertise and conviction in battery flexibility. This additional capital—beyond prior investments—validates Entrix's leadership in managing 3 GW across 70+ assets. It shifts the company from pioneer to dominant player amid EU pushes for resilient power systems.
Europe BESS Market Scales Rapidly
The European battery energy storage system market stood at $1.96B in 2024, projected to reach $18B by 2030 at 14.4% CAGR according to MarketsandMarkets. Regulatory tailwinds like REPowerEU accelerate deployments, driving demand for optimizers. Entrix's multi-country presence outpaces single-market rivals.
McKinsey Veteran Leads Expansion
Founder and CEO Steffen Schülzchen brings McKinsey energy practice experience, complemented by Head of Operations Timo Scholz from gridX, acquired by E.ON. Their backgrounds in strategy and grid tech enable rapid scaling, with over 20 hires in early 2026 across sales, data, and operations.
Iberian Growth and Hiring Spree
Entrix eyes Iberian flexibility services growth, following entries in Spain and Portugal. A hiring surge—7 new roles in March 2026 alone—targets sales managers, data analysts, and engineers. New projects like MW Storage's 200 MWh in Bavaria signal continued pipeline momentum.
