Editor’s Note: In celebration of Earth Day on April 22, we will share updates throughout the week on a series of clean energy projects that we are developing. These projects represent some of the concrete steps that we are taking to deliver on our pledge to reach net-zero greenhouse gas emissions by 2045.

The Future of Energy Storage 

Breaking ground in April 2021, our Kearny Energy Storage Project is another exciting energy storage project that will help advance our renewable energy goals.  

Battery storage works by absorbing electricity when it’s abundant on the power grid and putting the power back on the grid when it’s most needed, such as during the evening after the sun sets and solar energy fades away. 

Located at our operations center in Kearny Mesa, two separate lithium-ion battery storage systems will be built to provide a total of 20MW, or 80MWh of power to our local grid. This is equivalent to powering about 13,000 residential customers for roughly four hours. 

The facility is anticipated to begin operation in late summer/early fall 2021. The Kearny Energy Storage project is in alignment with what has been directed by the state to procure energy storage, and we expect to develop or interconnect more than 330MW of energy storage by 2030. 

Currently, our company owns and operates 13 energy storage projects, totaling about 45MW of energy storage. The Kearny Energy Storage Project is part of our overarching sustainability initiative to become carbon-neutral by the year 2045. To learn more about these goals, please visit here.
