What JEMA ENERGY does

JEMA Energy, S.A. is a Spanish power electronics designer and manufacturer founded in 1954 and headquartered in Lasarte-Oria, Gipuzkoa, in the Basque Country. The company is a wholly-owned subsidiary of the Irizar Group, a diversified industrial conglomerate founded in 1889 with approximately 1,500 employees and €500 million in annual billing across bus manufacturing, ITS communications, and rotating machinery. JEMA specializes in static power converters and turnkey energy conversion systems, operating across four primary areas: renewable energies (solar PV inverters, BESS converters, green hydrogen), e-mobility (depot and opportunity EV chargers from 50 kW to 300 kW and beyond), Big Science and nuclear fusion research (precision high-voltage and high-current power supplies for CERN, DESY, and similar facilities), and railway/grid services (STATCOM/SVC reactive power compensation, test benches, braking energy recovery).

The company's core technology platform centers on modular, bi-directional power electronics with proprietary multilevel topologies, enabling configurable products such as the X8 series (1500 Vdc, up to 4.7 MVA, configurable as PV inverter, BESS converter, or fuel cell rectifier). Precision offerings include high-voltage power supplies with output current stability below 0.001% over 24 hours and ultra-fast response times under 20 ms for solar inverters. JEMA invests approximately 10% of sales in R&D with more than 50 dedicated engineers and maintains collaborative relationships with research centers including Tecnalia, Cidetec, Fraunhofer, and Irizar's Creatio R&D center.

JEMA monetizes primarily through direct enterprise sales of customized hardware and turnkey solutions, supported by after-sales services (technical support, spare parts, preventive and corrective maintenance, training). Pricing is quote-based with no public list prices. The company reaches global markets through regional offices in Spain, Mexico, and the USA, supported by an active presence at industry events (Intersolar, Busworld, RE+, UITP) and direct engagement in international tenders for large-scale projects. The customer base spans public transportation (RATP, SNCF, RDT 13), rail (Eurotunnel, CAF, Bombardier), space and research (NASA, CERN/JET, DESY), energy (Técnicas Reunidas, Endesa X), and medical/industrial (IBA). The firm claims presence across 90+ countries on five continents.
