What FERESTO does

FERESTO GmbH is a German limited liability company (GmbH) founded in 2021 and headquartered in Iggensbach, Bavaria, with an additional office in Deggendorf. The company operates as a wholly-owned subsidiary of FENECON GmbH, a German energy storage manufacturer, and rents industrial-scale battery storage systems to commercial and industrial customers. FERESTO also structures participation mechanisms that allow investors to participate in large-scale storage projects whose revenues are tied to EEX energy market activity and grid services. The company serves customers across Bavaria, North Rhine-Westphalia, and Styria (Austria), with publicly named reference projects including a McDonald's franchise in Spital am Semmering, the Bavarian Forest Company in Zwiesel, and The Mobility House in Elverlingsen.

The core product line consists of three industrial battery storage units — FENECON Industrial S, M, and XL — built on FENECON's underlying hardware platform. Rental terms are flexible and quote-based, ranging from days to multiple years, and include a reduced-price purchase option at the end of the rental period. Reference partnerships include GreenVesting Solutions GmbH, The Mobility House, BVMW, and ElectroFleet. FERESTO holds the EMPower Award (2023) and maintains a small team of approximately 6–9 employees. The company exhibits at major European energy storage trade fairs, including ees Europe 2026.

The business model combines a hardware-rental revenue stream with project-based investment participation in larger storage assets. Pricing is quote-based rather than standardized, and FERESTO does not appear to have raised external funding or disclosed financial metrics. The combination of rental flexibility, the FENECON hardware backbone, and investment participation structures positions FERESTO as a capital-light commercial-storage vehicle within the FENECON group rather than a vertically integrated storage developer.

Direct peers

• The Mobility House: Joint operator of the Elverlingsen 3.6 MW / 8,136 kWh project with FERESTO and a strategic partner. Comparable in combining EV-charging infrastructure with stationary battery storage and energy market participation in DACH, serving overlapping commercial and industrial customers.
• TESVOLT AG: German manufacturer of commercial and industrial battery storage systems, including high-power variants for peak shaving, EV charging, and off-grid. Directly comparable product portfolio targeting the same C&I customers in DACH, though TESVOLT focuses on sales rather than rental.
• Aggreko plc: Global provider of temporary power and temperature-control solutions, increasingly including battery storage rental and mobile energy storage. The closest analog to FERESTO's rental-led, short-to-medium-duration industrial storage model, with substantially larger scale and geographic reach.
• Stem Inc. US-headquartered AI-driven commercial and industrial energy storage provider with an asset-light 'storage-as-a-service' model. Closely comparable in C&I customer targeting, energy market participation, and the recurring-services revenue model, though operating in North America rather than DACH.
• Sonnen GmbH: German-based energy storage company (now part of Shell) offering residential, commercial, and industrial battery storage solutions including virtual power plant aggregation. Closely comparable in product category, geography, and end-customer profile, though with a different (largely sales-based) commercial model rather than rental.

Broad incumbents

• Wärtsilä Energy Storage: Finnish technology group with a significant grid-scale energy storage business (including the former Younicos platform). Comparable in large-scale battery storage integration and grid services participation in European energy markets, serving utilities and industrial customers.
• Fluence Energy: Global grid-scale energy storage integrator and service provider, active across Europe including Germany. Comparable in energy market participation, EMS/software layer, and industrial-scale deployments, though focused on utility-scale projects rather than C&I rental.
• FENECON GmbH: Parent company of FERESTO and the manufacturer of the FENECON Industrial S, M, and XL product lines. Directly comparable as a German industrial battery storage provider, but operates as a broader hardware-and-solutions business with its own direct sales channels, giving it significant overlap with FERESTO's offering.

Emerging players

• GridBeyond: Ireland-based demand-response and distributed energy resource platform operating across European energy markets. Comparable in optimizing behind-the-meter and front-of-meter storage assets for energy market participation, though delivered as a software/service layer rather than a hardware renter.
• Lichtblick SE: German energy services company with a virtual power plant aggregating distributed energy assets including residential and commercial storage. Comparable in marketing flexibility and energy market optimization to industrial and commercial customers, though primarily upstream of hardware ownership.
