The Notrees Project will analyze and discern how, when integrated with wind power, energy storage can compensate for the inherent intermittency of this renewable power generation resource. Incorporating both existing and new tools, technologies and techniques, this demonstration project will provide valuable information regarding wind energy storage and serve as a model for other entities to adapt and replicate. The energy storage system will be designed and constructed using fast response, advanced lead-acid batteries configured to provide 36 MW output peak power with an energy storage capacity of 24 MWh.

The Department of Energy's Office of Electricity (OE) recognizes that our nation's sustained economic prosperity, quality of life, and global competitiveness depends on an abundance of secure, reliable, and affordable energy resources. OE leads the Department of Energy's efforts to ensure a resilient, and flexible electricity system in the United States. Learn more about OE >>
