The continued growth of utility-scale renewable energy projects is driving demand for experienced engineering, procurement and construction contractors. Mortenson has secured the No. 7 position in the 2026 U.S. solar contractor rankings, reflecting its recent project delivery activity across the country's expanding solar market.
The annual ranking is based on the total solar generation capacity installed during the previous year. Mortenson reported participation in projects totaling nearly 2 gigawatts of installed solar capacity during 2025.
The contractor's renewable energy portfolio now includes more than 120 completed solar projects across 19 states, supported by 17 years of engineering, procurement and construction experience in the solar sector.
Mortenson provides EPC services from preconstruction through commissioning, supporting utility-scale renewable energy developments for public and private sector clients.
In addition to construction services, Mortenson offers in-house capabilities that include energy modeling, technology evaluation and self-perform construction to support project execution.
The company also delivers large-scale solar facilities in a variety of geographic and site conditions, serving developers and energy owners seeking utility-scale renewable generation capacity.
As utilities, independent power producers and developers continue investing in renewable energy infrastructure, contractors with established EPC experience remain important delivery partners for large-scale solar projects. Rankings based on installed capacity provide insight into firms actively supporting the growing U.S. clean energy construction market.
