Bp and Iberdrola choose Toledo-based Imefy to supply the main transformer for their green hydrogen plant

Bp and Iberdrola have awarded the Toledo-based company Imefy the contract to manufacture and supply the transformer for the largest renewable hydrogen production plant in Spain (25 MW), which will be located at the bp refinery in Castellón. 

Imefy, headquartered in Los Yébenes, a municipality located in the province of Toledo, will manufacture, supply and supervise the assembly and commissioning of the three-phase power transformer, with 37 megavolt-amperes (MVA) of power and a 66/30 kilovolts (kV) transformation ratio, and will be supplied in the first quarter of 2026.

This award demonstrates bp and Iberdrola’s confidence, through the company created for the Castellón Green Hydrogen project, in Spanish companies in the development of the renewable hydrogen value chain, contributing to the integration of the territory and the creation of industrial and innovation opportunities in a growing market, acting as a lever for development. 

The project is expected to be operational in the second half of 2026 with an investment of more than €70M. In later phases of the project, the green hydrogen produced could also be used in key industries that are difficult to decarbonise in the Valencian Community, such as ceramics, to replace the natural gas used in their processes, in chemical industries and in heavy transport.
