8minutenergy is wholly owned by Buttgenbach and his management team as of 6 December 2018. Buttgenbach, who co-founded 8minutenergy in 2009, led a management buyout of the shares of fellow co-founder Martin Hermann last week.

Buttgenbach noted: “We thank J.P. Morgan and Upper Bay for bringing the long-term focus and financial resources to enable us to unleash the full potential of our pipeline and incredibly talented team.

“We have been the largest and most successful solar developer in California, and have expanded our cost leadership across the US, developing a solar and storage project pipeline of 10.7GW. A testament to our low-cost leadership is the 420MW Eagle Shadow Mountain Solar plant in Nevada, which at 2.3 cents/kWh fixed for 25 years, holds the record for lowest-price solar PPA in the nation. In Texas, which is a purely price-driven competitive market, we will start construction of our 280MW Holstein 1 power plant in the second quarter of 2019.”

Michael Lehman, managing director and portfolio manager of J.P. Morgan Asset Management, said: “We’ve been very impressed with the 8minutenergy team and their ability to deliver sustainable returns through their utility-scale solar projects. 8minutenergy has a premier development process that consistently delivers attractive solar projects with long-term, contracted cash flows.”

8minutenergy also announced that Alex O’Cinneide, founder and CEO of Gore Street Capital, will rejoin the Company’s advisory board.

O’Cinneide said: “I am excited to rejoin the advisory board of the company as it continues its extraordinary growth path. I look forward to leveraging the experience of financing utility-scale energy storage projects for the company, gained through running the first publicly traded fund established to invest in diversified utility-scale energy storage projects.”

PV Tech has been running PV ModuleTech Conferences since 2017. PV ModuleTech USA, on 16-17 June 2026, will be our fifth PV ModulelTech conference dedicated to the U.S. utility scale solar sector. The event will gather the key stakeholders from solar developers, solar asset owners and investors, PV manufacturing, policy-making and and all interested downstream channels and third-party entities. The goal is simple: to map out the PV module supply channels to the U.S. out to 2027 and beyond.
