14 October, 2026TM Telleria, a company based in Urretxu (Gipuzkoa), specialises in machining mechanical components for hydroelectric power plants. Founded in 1976, the company has evolved from providing machining services for the local market to becoming a supplier to international engineering companies operating in the sector.
Currently, 90% of its business is linked to the hydroelectric sector, while the remaining 10% is divided between the naval, aerospace and automotive industries. Although machining remains its core activity, the company offers comprehensive solutions ranging from raw material sourcing and procurement to testing, partial pre-assembly and other complementary processes, including the production of highly complex components.
TM Telleria employs approximately 50 people, generates an annual turnover of around €10 million and exports 80% of its production, primarily to France, Germany, Finland, the United States and Canada. The company expects to increase its annual turnover to €15 million over the coming years.
The company is also completing the relocation of all its operations to its new facilities in Urretxu, where its production area will increase from 3,600 to 6,900 m². Its future objectives include expanding its international presence, advancing its use of data analytics and artificial intelligence, and continuing to improve the digitalisation and security of its processes.
