IMEFY has signed an agreement with Iberdrola and bp for the manufacturing and supply of the power transformer for Spain’s largest renewable hydrogen production plant.

A milestone in sustainable electrification

IMEFY will supply a three-phase 37 MVA power transformer with a transformation ratio of 66/30 kV. This equipment will be essential to ensure the proper functioning of the 25 MW electrolyzer that will produce green hydrogen at Iberdrola and bp’s plant in Castellón. Delivery and commissioning are scheduled for the first quarter of 2026.

The trust placed in IMEFY by Iberdrola and bp, through the Castellón Green Hydrogen partnership, highlights the importance of Spanish companies in the development of innovative energy technologies. This contract strengthens IMEFY’s position as a key player in the sector and demonstrates its ability to handle large-scale projects.

Impact of the project on the energy transition

The Castellón renewable hydrogen plant will be the largest in Spain and will be powered by electricity from renewable sources, supplied by Iberdrola through a power purchase agreement (PPA). With an investment exceeding 70 million euros, this facility aligns with industry decarbonization goals by replacing gray hydrogen (produced from natural gas) with green hydrogen, enabling a reduction of 23,000 tons of CO₂ annually.

This development will not only benefit BP’s refinery but could also, in later phases, be extended to key industrial sectors such as ceramics, chemicals, and heavy transport in the Valencian Community. Additionally, the project has received 15 million euros in funding through Spain’s Recovery, Transformation, and Resilience Plan, supported by NextGenerationEU funds.

IMEFY: Innovation and leadership in the sector

IMEFY’s CEO, Eduardo Fontecha, emphasized the importance of this contract for the company: “The main feature of this transformer is that its power is not standard (37/33 MVA). However, the most important aspect is its location: the green hydrogen plant in Castellón. We already work regularly with Iberdrola and BP, but this project is very emblematic and will provide us with a significant reference both nationally and internationally.”

Securing the transformer supply contract for the Castellón plant represents a significant achievement for IMEFY. As the demand for green hydrogen continues to grow, IMEFY remains at the forefront of innovation in the sector, demonstrating its ability to meet future challenges.
