Blue Oak Energy was a prominent U.S. solar engineering and construction (EPC) firm specializing in commercial and utility-scale photovoltaic (PV) systems. Founded in 2003, the company provided comprehensive services from design and engineering to procurement and construction management. Known for its technical expertise and project execution, Blue Oak Energy played a significant role in the development of numerous solar projects across North America. The company was acquired by Coronal Energy in 2015, which was subsequently acquired by Sonnedix in 2019, integrating Blue Oak Energy's legacy and capabilities into a larger global renewable energy platform.
The headquarters served as the central hub for Blue Oak Energy's engineering, project management, business development, and administrative operations for its solar projects across North America.
As a company focused on sustainability, its office space likely reflected practical and efficient design, possibly incorporating energy-efficient features. Davis itself is a bicycle-friendly city with a strong emphasis on green living.
Blue Oak Energy fostered a culture of innovation, technical excellence, and a commitment to advancing solar energy. Employees were passionate about renewable energy and contributing to a sustainable future, working in a collaborative and engineering-focused environment.
The Davis headquarters was significant as the operational core from which Blue Oak Energy managed the design and construction of hundreds of megawatts of solar capacity, contributing to California's and the nation's renewable energy goals.
Prior to its acquisition, Blue Oak Energy primarily focused its operations within the United States, providing solar engineering and construction services for commercial, industrial, and utility-scale projects across various states. While now part of Sonnedix, a global solar IPP, Blue Oak Energy's original scope was North American.
