Pattern Energy Group Leadership

I serve as the Chief Executive Officer of Pattern Energy and Pattern Development, a position I have held since I co-founded Pattern Energy Group (Pattern) in 2009. I oversee all aspects of Pattern Energy and Pattern Development, but my efforts are largely focused on corporate and industry strategy, capital formation, market and project selection, corporate performance and corporate culture. I am based out of the San Francisco office.

For over 30 years, my career has focused on developing, constructing, managing, and investing in energy and infrastructure projects in the United States and around the world. I closed my first wind project financing in 1989, and have since successfully managed or oversaw the development, investment and operations of nearly 10,000 megawatts of renewable energy projects worldwide and nearly $50 billion of infrastructure assets.

Prior to joining Pattern, I was a partner at Babcock & Brown from 1986 to 2009. As leader of Babcock & Brown’s North American Infrastructure Group, I initiated and was responsible for project finance activities, energy project development and investment, and energy and infrastructure funds management for institutional investors. Previously, I worked for the State of California as Chief of Energy Assessments from 1975 to 1986.

My wife Gigi and I co-founded The Bay School, a high school in San Francisco that focuses on technology and ethics. We also support the University of California, Berkeley’s Physics Department and the University of Washington’s Medical School and I sit as an active Trustee of the University of California, Berkeley Foundation.

Mr. Armistead serves as President of Pattern Development, and the Executive Vice President of Business Development of Pattern Energy, a position he has held since June 2009. As President of Pattern Development, Mr. Armistead will have continuing responsibility for all development and origination activities at Pattern Development, as well as the broader responsibility for running the Pattern Development day to day business.

As the Executive Vice President of Business Development, Mr. Armistead leads all global business development, including construction, engineering, and major equipment procurement. Mr. Armistead values the opportunities his position affords him to create new renewable energy projects that become part of the long-term energy infrastructure.

Prior to his time with Pattern Energy and Pattern Development, Mr. Armistead spent 10 years overseeing Babcock & Brown’s North American renewable energy business, including development, construction, and operations. In previous roles, he led financing efforts for Edison Mission Energy and developed multiple cogeneration facilities for Conoco. Mr. Armistead has a Bachelor of Science in electrical engineering from Rice University. He is based out of the Houston office.
