Enel Green Power announced the completion of its first hybrid wind project, Azure Sky Wind + Storage, as well as the addition of battery storage facilities at the Roadrunner and High Lonesome renewable project sites in Texas.
The Azure Sky wind + storage project and storage additions at Roadrunner and High Lonesome help to add measurable value in the form of storage capacity and reliability to support the state’s electricity system, said Paolo Romanacci, head of Enel Green Power in the US and Canada.
Azure Sky wind + storage, located in Throckmorton County, has a 350 MW wind power facility in order to generate around 1.3 TWh of renewable energy yearly, paired with a 137 MW/205 MWh battery storage facility.
Enel Green Power signed a power purchase agreement (PPA) with partners such as Akamai, MilliporeSigma, Synopsys and Uber. Kellogg Company, HP Hood and lululemon also signed PPAs to purchase clean energy output.
Enel Green Power has installed grid-connected battery systems at the sites of the Roadrunner solar and High Lonesome wind projects. Each battery system will add 57 MW/86 MWh of storage capacity to the grid. The systems will help balance intermittent generation profiles in the renewables-saturated western region of ERCOT.
With a total of 170 MWh of battery storage capacity between the two projects, Enel can dispatch flexible capacity, providing services to support resiliency amid shifting grid conditions in ERCOT. By early 2023, Enel will operate a portfolio of 12 battery energy storage systems able to store over 1,290 MWh in Texas.
Enel Green Power plans to add 6.5GW of new renewable generation and 2,600 MWh of storage capacity to the grid in the US and Canada by the end of 2024.
