Our renewable technologies
ACCIONA is a global leader in the development, construction, operation, and maintenance of wind power facilities, with more than 30 years of experience in the sector.
ACCIONA is a pioneer in the installation of large photovoltaic plants. We build and operate some of the largest solar installations on the planet.
Hydropower energy has been with us since our earliest steps in the sector, providing us with solid expertise in this renewable technology, from resource assessment to the design, construction, operation, and maintenance of facilities.
ACCIONA led the revival of solar thermal energy in 2007 when it commissioned the Nevada Solar One plant in the USA. The company boasts extensive experience in the engineering, procurement, construction and operation of solar thermal plants, at the service of clients as an EPC (turnkey) project contractor.
At ACCIONA, we are experts in sustainable biomass solutions across the entire value chain, including the design, construction and operation of major biomass plants for large-scale power generation.
In 2017 we installed the first battery storage plant linked to a wind farm. We are committed to new storage technologies. These are essential to create an electricity system in which renewable energies account for the greatest possible share.
Activity areas
Our renewable generation portfolio across five continents allows us to offer a reliable, competitive and 100% clean electricity supply globally.
We design customised solutions to optimise and decarbonise the energy consumption of companies, businesses, communities and towns and cities, while reducing energy bills and digitising energy management.
We design self-consumption solutions based on renewable technologies for large companies, SMEs, and businesses, tailoring the size of the facilities to the needs of each customer in order to maximise energy savings.
We are pioneers in the use of green hydrogen in the various stages of the value chain, including production, storage, transportation, distribution and end use, ensuring traceability for the customer, which guarantees that the product used is 100% renewable from source to destination.
We offer corporate and institutional customers electrical mobility solutions through the installation, management, operation and recharging infrastructure maintenance for electric vehicles.
