The solar farm will be built with a €217m ($233.6m) investment in the municipality of Villalba de Guardo in the province of Palencia.
The facility will feature more than 630,000 modules and will generate enough energy to power 180,000 homes a year.
Iberdrola said the facility will have a ‘significant’ local component and estimates that up to 850 industrial suppliers will be involved in the project during peak periods.
In a statement, the company said: “(The project) will also have a regional vision; the substation will be built by the Salamanca company Tecinsa and the metal supports of the plant’s structure will be built by Made Tower, located in Medina del Campo, Valladolid.
“In addition, different regional and national suppliers will produce different components or carry out their electrical infrastructures, such as the overhead line, which will be provided by the Asturian supplier Tensa, and the power transformers and isolating switches by the Andalusian company Hitachi and the Basque company Mesa, respectively.
