Iberdrola has commissioned a 243 MW solar plant in Italy and has also started building a 41 MW/82 MWh battery energy storage system (BESS) in the United States.

Iberdrola is building the Shutler BESS in Gilliam County, Oregon. The project, which is being developed by Iberdrola subsidiary Avangrid, will have 41 MW of power and 82 MWh of storage capacity.

Avangrid has about 3 GW of generation capacity in the northwestern United States. The Shutler battery system is scheduled to enter operation in 2027.

Separately, the Spanish utility said its Fénix solar plant in Sicily is now operational. A significant share of the plant’s output has been contracted under long-term power purchase agreements (PPAs) with Italian companies. The project also received financing from the European Investment Bank.

Opinion & Analysis

Falling li-ion battery prices mirror solar photovoltaics trends: Is there a role for second-life batteries before recycling? Lithium-ion batteries are everywhere, powering everything from consumer electronics to electric vehicles, residential PV storage systems, and, more recently, mitigating curtailment in large-scale wind and solar power plants. EVs are driving large-scale demand for Li-ion batteries which will result in substantial volumes of spent batteries in the near future. This scenario highlights the potential for repurposing EV batteries for second-life stationary applications, which could maximise their value before recycling. However, to fully realise this opportunity, several economic, technical, and regulatory challenges must be addressed and resolved.
