Iberdrola is building its first large-scale battery in the United States

The project will boost energy storage capacity in the country.

Shutler will have a storage capacity of 41 MW and 82 MWh and will enhance the reliability of the electricity system on the northern Pacific coast, where the Group has 3,000 MW of generation capacity

Iberdrola is expanding its investments in energy storage into the United States market with the construction of its first battery facility in the country. The Shutler project, located in Gilliam County, Oregon, has an installed capacity of 41 megawatts (MW) and a storage capacity of 82 megawatt-hours (MWh).

Shutler will help to strengthen the stability of the electricity grid in the north-west of the country, on the Pacific coast, where Avangrid — the Group’s US subsidiary — already has 3,000 MW of generation capacity. The project forms part of Iberdrola’s strategy to implement solutions that facilitate the integration of renewable energy and improve the system’s resilience against a backdrop of growing electricity demand.

The project will enable energy to be stored during periods of low consumption or high renewable generation and released when necessary, optimising the energy system and promoting a real-time balance between supply and demand. This type of infrastructure is becoming increasingly important in the context of growing electrification.

The project, which is scheduled to come on stream in 2027, will be located alongside other Avangrid renewable energy facilities already in operation or under development in the area.
