Spain’s leading infrastructure and renewable energy company ACCIONA has announced the beginning of operations for what the company is billing as the world’s first hybrid grid-connected wind project with battery storage.
ACCIONA announced on Monday that it had started up a small yet pivotal project that for the first time combines a wind project with an energy storage system using two separate batteries. The project is small, as befits a pilot project of this sort, made up of a single 3 megawatt (MW) wind turbine and two batteries situated in separate storage containers — a fast-response 1 MW/0.39MWh Li-ion Samsung battery that can maintain 1 MW of power for 20 minutes, and a slower-response 0.7 MW/0.7MWh battery that can maintain 0.7 MW for 1 hour.
In addition to the pilot project, ACCIONA has developed simulation software that it will use in conjunction with the project.
The company aims to integrate grid-connected storage solutions and analyze other applications to provide electricity during periods of peak demand, which will increase the cost-benefits of the project.
