Zigor

What Zigor does

Zigor Corporación S.A. (ZGR) is a Spanish power electronics manufacturer founded in 1998 and headquartered in Vitoria-Gasteiz, Spain, designing and producing equipment for electrical energy management and power quality. Its core portfolio centers on Dynamic Voltage Restorers (DVR) — including medium-voltage SET DVR units up to 6.6 kV — industrial double-conversion UPS systems (SEPEC, 200-800 kVA), bidirectional Power Conversion Systems for utility-scale 1500V battery energy storage (PCS 3000 and PCS 4500, achieving up to 98.8% efficiency), and active harmonic filters. Technology differentiators include sub-5ms voltage-sag compensation without batteries, industrial air cooling for high-power outdoor applications (IP55, full power to 50°C), and a modular architecture enabling retrofit and incremental capacity expansion.

ZGR serves four primary business lines: Energy Generation and Storage (PV developers, BESS integrators), Industrial Manufacturing (oil and gas, automotive, food and beverage, pharmaceuticals, electronics), Transmission and Distribution (utilities and grid operators), and Electric Mobility, with data centres as a secondary segment. Revenue is generated through direct enterprise sales of custom-configured hardware and recurring technical services covering installation, commissioning, preventive/corrective maintenance, remote support, and predictive retrofit (extending equipment life by 5-15 years). Customers include Schneider Electric (global DVR supply partner since 2020), Mercadona (~39 MVA of UPS across 71 devices), Ecopetrol, Iberdrola, Acciona, and Abbott, with operational offices in Spain, Mexico, Colombia, and the US.

In May 2026, Nextpower agreed to acquire ZGR's power conversion business for $80.5 million, representing a partial divestiture of the company's modular inverter technology; ZGR retains its DVR, UPS, PCS, and service operations. The company employs 51-100 people and invests approximately 20% of revenue into R&D, including the CONFIA project with TECNALIA on AI-based reliability prediction for power electronic components.

Partnerships

Three partnerships are on record, tiered minor and core.

• Nextpower (formerly Nextracker)minorStrategic or Co-development Partner · 14 May 2026Nextpower acquired ZGR's power conversion business for $80.5 million in May 2026. The deal included modular inverter technology applicable to solar plants, battery storage, and data centres. Production from the acquisition was expected to ramp up in 2027. This represents a divestiture of a portion of ZGR's product portfolio.
• Schneider ElectriccoreStrategic or Co-development Partner · 1 January 2020Framework agreement since 2020 under which ZGR is a global supplier of DVR systems (Dynamic Voltage Restorers) for demanding industrial environments. In 2024, the alliance was strengthened with a new framework contract for Intermediate Power and High Power DVRs, plus Low and Medium Voltage solutions in Colombia and Latin America. ZGR provides specialized training to Schneider Electric technicians. ZGR acts as long-term technology partner beyond simple equipment supply.
• TECNALIAminorStrategic or Co-development PartnerTECNALIA, a Basque research organisation, coordinated the CONFIA project in which ZGR participated alongside other actors in the Basque science and innovation network. The project developed AI-based models, non-invasive measurement systems, and advanced prognosis algorithms to improve reliability of critical components (silicon IGBT semiconductors and capacitors) in power electronic converters. Funded by the Basque Government's ELKARTEK programme.
