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

Reinforces 8minute’s position as a clean technology leader and signals a new phase of growth

LOS ANGELES & SAN FRANCISCO–(BUSINESS WIRE)–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.”

Blair Thomas, EIG’s Chairman and CEO. “We’re thrilled to be able to help fuel long-term, sustained growth for 8minute and remain committed to supporting the company’s new ventures and future endeavors.”
