Southern Power, a subsidiary of Southern Company, has partnered with lithium-ion battery storage projects developer esVolta for energy storage projects in California.

Under the terms of the deal, the two companies have agreed for four utility-scale energy storage projects located in California totalling more than 86MW capacity.

esVolta founder and president Randolph Mann said: “The consummation of our new partnership with Southern Power represents a tremendous milestone for esVolta. Southern Power is an outstanding company and a leader in the US electricity sector.

“Our collaboration will enhance esVolta’s ability to capitalise on the strong growth of the energy storage business, and we are excited to work alongside the outstanding team at Southern Power to bring additional high-quality utility-scale storage projects to fruition for our utility customers.”

One project received investment, whilst the other three are subject to completion. The partnership with esVolta is in line with Southern Power’s growth and low-risk business strategy, which focuses on developing or acquiring interests in projects covered by long-term contracts.

Southern Power president Bill Grantham said: “Battery storage is an emerging technology with the potential to revolutionise how energy is supplied.

“These projects and our partnership with esVolta are a great strategic fit for our business, and these transactions will further position Southern Power to meet our customers’ needs as the energy industry continues to evolve.”

In October 2018, Southern Power announced that it will construct a 200MW wind facility in Kansas, after signing an agreement with global cruise vacation company Royal Caribbean Cruises.

The new Reading Wind facility is Southern Power’s eleventh wind facility, which will be developed in Osage and Lyon Counties of Kansas.
