What GAZ Geräte- und Akkumulatorenwerk Zwickau does

GAZ Geräte- und Akkumulatorenwerk Zwickau GmbH, commercially branded as GAZ ENERGY, is a Zwickau-headquartered German private limited company (GmbH) that designs and manufactures battery and energy storage solutions with a heritage dating to 1884 and a reported footprint in more than 120 countries. The product portfolio is built around two pillars: legacy nickel-cadmium (Ni-Cd) cells in the Lomain range, optimized for ultra-low maintenance in datacenter UPS applications, and the SOL range, engineered for harsh-environment industrial uses such as oil and gas pipeline impressed-current cathodic protection (ICCP) and solar-backed railway signaling; and a newer line of grid-scale liquid-cooled battery energy storage systems (BESS) available in 17.5-30 MW / 40-60 MWh configurations, paired with a proprietary controlling software developed in cooperation with Second Foundation for energy trading and cybersecurity defense.

The company sells primarily through direct enterprise field sales, targeting large infrastructure projects (typical installations in the 20-50 MWh range) where technical safety, cybersecurity, and spare parts availability are decisive procurement criteria. Named customers include Decci Group (Czech Republic Vraňany BESS, 20 MW / 40 MWh), Second Foundation (Finland Rautavaara BESS, 30 MW / 60 MWh), a major European datacenter operator using Lomain cells for UPS, Saudi Arabian oil and gas pipeline operators using SOL cells for ICCP, and a Mexican railway operator using SOL G cells across approximately 200 sites starting from Veracruz. Revenue is not publicly disclosed, cumulative project capacity now exceeds 1.5 GWh as of June 2026, and the company has no disclosed parent, subsidiaries, or external funding rounds.

The business model is grounded in hardware sales of bespoke battery systems to enterprise buyers, with project-based engagement led by sales specialists and supported by a multi-language online Ni-Cd sizing calculator. The company employs between 51 and 100 people, operates a registered office in Zwickau, and markets on European manufacturing origin, cybersecurity-first design, and local support infrastructure. Marketing channels are concentrated in the corporate website (gazenergy.cz), participation in industry events such as Intersolar 2026, and direct customer consultation, with no third-party distribution or marketplace presence disclosed.

Core offering

GAZ manufactures and sells grid-scale liquid-cooled Battery Energy Storage Systems (BESS) in multi-megawatt configurations with proprietary controlling software for energy trading and grid stability, alongside nickel-cadmium (Ni-Cd) battery cells across the Lomain range (for datacenter and UPS backup) and the SOL range (for harsh-environment applications such as oil & gas pipeline cathodic protection and railway track circuits). Products are engineered and supplied to enterprise customers across energy utilities, data centers, transportation, and aerospace & defence sectors in over 120 countries.

Product overview

GAZ ENERGY operates as a European energy storage solutions provider building upon over 140 years of innovation. The company offers a portfolio of battery and storage products centered on two main categories: BESS (Battery Energy Storage Systems) — grid-scale liquid-cooled systems with custom controlling software available in various capacity configurations (20-30 MW / 40-60 MWh) — and Ni-Cd batteries spanning the Lomain range (for UPS/datacenter applications) and SOL range (for harsh environments such as pipelines and railways). The product portfolio is complemented by an online Ni-Cd Calculator tool for battery sizing. The company serves markets across energy storage, industry, mobility, and aerospace & defence sectors, with projects in Europe, the Middle East, and Latin America.

Partnerships

Two partnerships are on record, tiered core and flagship.

• Second FoundationcoreStrategic or Co-development PartnerSecond Foundation is a technology company in the energy sector active in 30 countries. They are a principal investor in the BESS project in Rautavaara, Finland (30 MW / 60 MWh) and have contributed to the development of GAZ Energy's BESS controlling software, which enables particularly efficient energy trading and maximum protection against cyber threats.
• Decci GroupflagshipTechnology or IntegrationDecci Group, led by CEO Darina Merdassi, operates the Vraňany BESS project (20 MW / 40 MWh) in Czech Republic. The project uses a shared grid connection with the Vepřek photovoltaic power plant. Technical and cybersecurity safety, efficiency, and guaranteed spare parts availability were key factors in selecting GAZ ENERGY as a partner.
