What Arteche does

Arteche is a Spanish electrical equipment manufacturer founded in 1946 that develops hardware and solutions for measurement, monitoring, automation, and reliability of electrical transmission and distribution grids. Its core products include instrument transformers (high voltage, medium voltage IEC/IEEE-ANSI, low voltage, and digital/optical for HVDC), protection and control relays (trip, supervision, auxiliary, railway SIL 4), IEC 61850 substation automation systems, power quality solutions (capacitor banks, harmonic filters), automatic circuit reclosers, and emerging flywheel-based energy storage systems (FESS) via its Teraloop investment. The portfolio spans the full grid measurement and protection stack, with proprietary technology in Distributed Fiber Optic Sensors (DFOS, via its Uptech Sensing stake) and optical current transformers that differentiate it in HVDC and digital substation applications.

The company operates through direct enterprise sales teams located in regional offices worldwide, supported by 80+ customer assistance points across more than 150 countries. It serves utilities and grid operators (Iberdrola, REE, RTE, CFE, National Grid, ESKOM), renewable energy projects (wind and solar grid connections), railway operators (Singapore Metro), data centers, and HVDC transmission projects. Revenue is generated primarily through quote-based project sales of hardware complemented by technical services, training, and maintenance contracts. Following its 2021 direct listing on the Spanish continuous market (BME Growth), Arteche has pursued an active inorganic growth strategy under its 2024-2026 'Energizing Futures Together' plan, including the 2025 acquisitions of RTR Energia and SEG Electronics (€50.6M), a minority stake in Uptech Sensing (2026), a joint venture with Mondragon for Amets Power Electronics (2025), and a JV with Hitachi Energy for gas-insulated transformers (2022). FY2025 results were record: €508.4M revenue, €80.5M EBITDA, and €45.3M net profit.
