Alconza Berango

What Alconza Berango does

Alconza Berango Sociedad Limitada is a Spanish designer and manufacturer of electric motors and generators, founded in 1960 and headquartered in Berango, Basque Country, Spain. The company operates as a wholly-owned subsidiary of Irizar Group and employs 51-100 people. Its core product portfolio addresses marine propulsion, on-board power generation, and hydroelectric applications, including main propulsion motors, permanent magnet motors, shaft generators, PTI/PTO systems, variable speed generators, monoblock and tandem motors, thruster motors, and medium- and low-voltage generators. The company also supplies electric motors for Irizar Group's electric buses, extending its technology into land-based electric mobility.

Alconza sells custom-engineered electromechanical systems directly to shipyards (including Samsung, Balenciaga, Helsinki Shipyard, Royal IHC, Freire, and Cammell Laird), vessel operators (Teekay, Hav Line Gruppen, Eidesvik, Swan Hellenic), and government maritime authorities (Rosmorport, Chilean Navy, NERC, British Antarctic Survey). Revenue is generated through project-based hardware sales, complemented by a lifecycle support offering that includes on-site services, remote engineering, commissioning, original spare parts, service centers, maintenance contracts, warranty extensions, and technical training. Pricing is quote-based and not publicly disclosed. The company maintains a 3,600 m2 production facility added in 2015 and holds ISO 45001:2018 and ISO 14001:2015 certifications, with a 13% carbon footprint reduction achieved in 2023.

The company's R&D activity is materially supported by the Basque Government's HAZITEK programme, with sustained grant participation across 2018, 2021, 2022, 2024, and 2025. Current innovation projects include ADPROM (high power-density motors), TWINPROP (digital twin for propulsion motors), and PRESCOR (superconductor-based propulsion with hydrogen cooling). Alconza's commercial differentiators include proprietary silent propulsion technology meeting DNV GL SILENT-R classification for research vessels, permanent magnet motor designs optimized for compactness and efficiency, and a custom-engineering model tailored to specific vessel operational profiles.
