E.ON Solar, a subsidiary of E.ON SE, completed the construction phase of Maricopa West, a 20-MW solar project located in Southern California. The complex has obtained a conditional use permit from Kern County, an incidental take permit from the California Department of Fish and Wildlife, and a habitat conservation plan under Section 10 of the Endangered Species Act from the United States Fish and Wildlife Service (USFWS). Maricopa West solar project will utilize single-axis tracking and consist of 89,000 photovoltaic panels.

SunEdison completed construction on New Hampshire's largest solar power plant, a 942-KW solar power plant for the town of Peterborough. SunEdison will supply solar energy generated by this system to the town over the next 20 years. SunEdison collaborated with Borrego Solar to complete the project after acquiring it from Borrego Solar earlier in 2015. The system was funded in part by a grant from the New Hampshire Public Utility Commission.
