The plant is designed to run as a base or intermediate load generator and is interconnected to the Hassayampa substation, which provides Arlington Valley direct access to the Palo Verde hub.  Arlington Valley’s capacity and associated output are committed during the summer months under an existing power purchase agreement through October 2019.
