PRESS RELEASE: Pattern Energy Group LP (Pattern Energy), a leader in renewable energy and transmission infrastructure, has closed an $11 billion non-recourse financing and begun full construction of SunZia Transmission and SunZia Wind, which together is the largest clean energy infrastructure project in U.S. history.
