What EEI does

EEI (Equipaggiamenti Elettronici Industriali S.p.A.) is an Italian power electronics company founded in 1978 in Vicenza, Italy, and currently operating under the direction and coordination of TECH EURO Sàrl with a wholly-owned branch (Shanghai E-EE Technologies Co. Ltd) in China. The company designs and manufactures custom power conversion systems — AC/DC and DC/AC converters, low and medium voltage drives, energy storage systems, harmonic filters, reactive power compensators, marine and submarine power systems, ropeway automation, and high-precision power supplies for particle accelerators and nuclear fusion. Its technology stack centers on IGBT-based converters, HV IGBT medium voltage architectures, Active Front End (AFE) design, and modular converter topologies; product specifications range from 100 kVA to multi-MVA with specialized precision metrics (response times as low as 12 microseconds for fusion, current ripple below 5 ppm for accelerator magnets). EEI holds ISO 9001, ISO 14001, SIL4 (STRMTG France), CEI 0-16, and CEI 0-21 certifications, and received the CERN CMS Gold Award in 2004 for its work on the LHC particle accelerator.

The company organizes its offering across seven business units — Energy Storage, E-Mobility, Renewable Energy, Industrial Applications, Marine Sector, Ropeways, and Big Science — and serves a customer base spanning energy utilities, heavy industry (steel, mining, cement), research institutions (CERN, MedAustron, CNAO), and public infrastructure operators. EEI reports more than 3,000 plants installed worldwide and approximately 500 orders produced per year; named reference customers include Construzioni Moncada (94.5 MWp South Africa PV plant), EBG MedAustron (90% of all converters at the Austrian hadrontherapy center), CNAO (Italy), GEK Terna (Kozani lignite mine), Hjulsbro Steel (Sweden), SAET Spa (Rwanda/Austria hybrid systems), Enertronica SpA (Eritrea backup), and Agudio (Turkish dam cableway). Go-to-market is direct enterprise sales through engineering and procurement engagement, complemented by trade show presence at KEY ENERGY, Intersolar Europe, IPAC, WIRE, Hydromatters, GENERA, and Solar Show Africa.

EEI's revenue model is primarily hardware sales of custom-engineered cabinet-based systems under project-based, quote-driven pricing with multi-year contracts, supplemented by technical services, scheduled preventive maintenance, training, and spare parts supply. Pricing is not publicly disclosed. The company is privately held under TECH EURO Sàrl with €2,875,000 fully paid-in share capital; no venture capital, public equity investors, funding rounds, or M&A activity are disclosed in the source materials. Growth levers are concentrated in (i) energy storage (MaxBESS, Rack Power Converters), (ii) E-mobility charging, and (iii) geographic extension through the Shanghai branch and emerging-market project wins.
