“With this agreement with Renfe, we can highlight electrification without emissions in transport, which is responsible for more than a third of all energy consumed in our country. Partnerships such as this one are essential to support the development of a renewable electricity mix. The PPAs, through their different modalities, are a key tool for customers who want to secure renewable energy at a fixed, long-term price”, David Martínez, director for clients in Spain at Iberdrola, said in a media release.
