What ECO STOR does
ECO STOR is a German-Norwegian privately held battery energy storage company founded in 2018 and headquartered in Oslo, with operational and project-development activities concentrated in Germany. The company develops, finances, constructs, and operates large-scale Battery Energy Storage Systems (BESS) using both first-life and second-life lithium-ion batteries, including its containerized ReCube product line (up to 2,500 kWh capacity and 1,440 kW power in a high-cube 20-foot format, supporting air-cooled and liquid-cooled batteries). ECO STOR's anchor asset is the 103.5 MW Bollingstedt facility in Schleswig-Holstein, Germany, and it is constructing the 300 MW/718 MWh Förderstedt project in Saxony-Anhalt—scheduled to be Germany's largest standalone BESS when operational in 2027.
The company's business model combines utility-scale BESS project development with recurring contracted revenue from long-term flexibility tolling agreements (e.g., a five-year deal with Next Kraftwerke covering 80% of Förderstedt's capacity) and cross-market optimization across day-ahead, intraday, and balancing energy markets. Route-to-market is delivered via strategic partners including Next Kraftwerke and Alpiq (VPP optimization), E.ON, Schleswig-Holstein Netz, and HanseWerk (grid integration and FCA framework co-development), and financial partners NORD/LB and Banco Santander (project financing). ECO STOR's ReCube brand extends the model to second-life battery repurposing for EV fleet operators and industrial users, with end-of-life recycling routed through partner LiCycle (up to 99% material recovery).
ECO STOR serves grid operators, utilities, energy companies, and IPPs across Germany, Italy, and the Netherlands. Differentiators include the industry's first interactive storage operations dashboard (free, open transparency platform built on live Bollingstedt data), open PyPSA-based energy-economic modeling tools, and demonstrated ability to structure Germany's largest BESS project financing. Pricing for utility-scale projects is project-specific and undisclosed; the ReCube product is quote-based with 6-9 month lead times for first systems and 3-6 months for subsequent containers.

Revenue model
- Battery Storage Project Development & Operation: ECO STOR develops, finances, constructs, and operates large-scale BESS projects. Revenue is generated through the sale of storage capacity services, grid stabilization, and renewable energy integration support. The Förderstedt project (300 MW/718 MWh) is Germany's largest standalone BESS once operational in 2027.
- Flexibility Tolling Agreements: Long-term tolling agreements with virtual power plant operators (e.g., 5-year deal with Next Kraftwerke covering 80% of Förderstedt capacity) provide contracted, predictable revenue streams. Tolling deals enable debt financing by reducing revenue uncertainty.
- Cross-Market Optimization: BESS assets optimized across multiple energy markets including day-ahead, intraday, and balancing energy markets, generating additional revenue from market-price-oriented trading on uncontracted capacity (20% of Förderstedt capacity).

ECO STOR product offering
Product offeringCore offering
ECO STOR develops, finances, builds, and operates large-scale grid-connected battery energy storage systems (BESS) using both first-life and second-life lithium-ion batteries. Through its ReCube product line, it provides containerized second-life battery storage solutions to industrial and fleet operators, and independently develops utility-scale projects such as the 300 MW/718 MWh Förderstedt facility in Germany, the largest standalone BESS in the country once operational.
Product overview
ECO STOR operates as a German-Norwegian battery storage company offering the ReCube product line, a modular containerized battery energy storage system (BESS) that utilizes both first-life and second-life batteries. The ReCube solution integrates used EV batteries into standardized container designs, enabling applications such as fast charging, peak shaving, and grid ancillary services. When second-life battery performance declines, the system facilitates end-of-life recycling through partner LiCycle, achieving up to 99% material recovery for new battery production.

ECO STOR competitors and assessment
Company assessmentBroad incumbents
- Tesla Energy: Tesla's Megapack and Autobidder platform compete with ECO STOR's ReCube product and optimization services at the utility-scale BESS level. Tesla operates across many markets and product lines, making it a broad incumbent rather than a focused European storage specialist.
- RWE: RWE is a major European utility developing large-scale renewable and storage projects across multiple markets. It competes with ECO STOR on utility-scale BESS development but as part of a much broader generation portfolio rather than a storage-focused platform.
- E.ON: E.ON operates distribution networks covering ~65% of Germany and is both a customer/partner of ECO STOR and a developer of its own grid and storage solutions. It overlaps as a broad incumbent in European grid services and storage deployment.
Direct peers
- Fluence Energy: Fluence is a global BESS OEM and project developer offering turnkey utility-scale energy storage solutions and asset performance services. It directly competes with ECO STOR in European utility-scale BESS development and operates similar tolling/optimization business models.
- Belectric: Belectric is a German-based EPC and O&M specialist for utility-scale solar and battery storage, now part of E.ON. It directly overlaps with ECO STOR in German BESS project execution and operations, though typically as a contractor rather than asset owner.
- Wärtsilä Energy Storage: Wärtsilä provides utility-scale BESS through its GridSolv product line and storage-as-a-service offerings across European markets. It directly competes with ECO STOR on EPC, optimization, and long-term service contracts for grid-scale storage.
- Nidec ASI: Nidec ASI supplies power conversion, energy storage, and grid integration solutions for utility-scale BESS projects across Europe. It directly competes with ECO STOR in delivering integrated BESS systems and storage-as-a-service offerings for grid operators.
- Giga Storage: Giga Storage is a Dutch utility-scale BESS developer and operator with operational and pipeline projects across the Netherlands and Belgium. It directly competes with ECO STOR in European grid-scale storage project development and uses comparable route-to-market agreements.
Emerging players
- Next Kraftwerke: Next Kraftwerke is a German VPP operator that aggregates and optimizes distributed assets across European energy markets. While ECO STOR's primary route-to-market partner, Next Kraftwerke is also expanding into own-asset storage and competes for optimization mandates on third-party storage assets.
- Octopus Energy Generation: Octopus Energy Generation develops and operates renewable and storage assets across Europe, including the Sessa Aurunca project co-developed with ECO STOR in Italy. It is an emerging player in European BESS development that partners with and competes against ECO STOR in select markets.
