8minute Solar Energy Closes $400 Million in Financing from EIG

8minute Solar Energy (“8minute”) today  announced  that  it  has  closed  $400  million  in  financing  from  EIG,  a  leading  institutional  investor in the global energy and infrastructure sectors. The financing agreement includes a portion of growth equity and a letter of credit. R. Blair Thomas, EIG’s Chairman and CEO, will join 8minute’s Board of Directors.

This strategic fundraise will help 8minute continue to operate and grow its attractive portfolio of clean  energy  assets,  which  includes  more  than  18  gigawatts  (GW)  of  solar  capacity  and  24  gigawatt hours (GWh) of storage throughout California, Texas, and the southwestern United States—enough energy to provide power for 20 million people. Importantly, this investment will enable 8minute to focus on technology innovation and advanced solar plant design, and to begin building projects on its own balance sheet.

“This strategic fundraise is not only a resounding vote of confidence in 8minute from a global energy investor that shares our vision for a zero carbon future, but also an important signal that the private sector recognizes the immediate need for more reliable, resilient and low cost climate solutions,” said Dr. Tom Buttgenbach, Founder and CEO of 8minute. “With EIG’s investment, we further solidify our role as a clean technology leader and become the leading technology provider of ‘smart’ solar power plants with integrated energy storage. As we look to expand into green hydrogen and other adjacent markets, a partner that understands this business is critical to our continued success.”
