Arteche develops equipment for the electric power industry, including generation, transmission, and distribution.

[1] Arteche divides its operations into three business units: instrument transformers, power grids, and turnkey solutions.

[clarification needed] After nine years in exile due to the Spanish Civil War and the Second World War, Aurelio de Arteche y Arana (1908–1983) returned to Bilbao, his hometown, in 1946 to accomplish his main life objective: creating a company like Usines Balteau, S.A., a company he knew during his exile in Belgium.

Thanks to help from friends, family and Marcel Balteau, Aurelio founded EAHSA, Electrotecnica Arteche Hermanos, S.A., in December 1946.

[3] During these years, Arteche expanded in the national market, becoming a benchmark for the Spanish power industry.

[5] The new logo is based upon a fractal, a succession of almost parallel lines, a structure that repeats itself at different levels, with Arteche's colours in gradients.
