Black Hollow Sun Solar Complex Begins Full Operations in Colorado

Platte River Power Authority and ContourGlobal have finished work on the Black Hollow Sun Solar Complex near Severance, Colorado. With a capacity of 257 megawatts, the facility features 544,740 photovoltaic modules. Full commercial operations began in September 2026, following the early completion of a 107-megawatt second phase. The site is expected to produce about 608 gigawatt-hours every year, providing enough electricity for more than 73,000 homes. This marks a major expansion of renewable energy capacity for Northern Colorado.

As the largest solar installation in the region, the Black Hollow Sun Solar Complex is a central part of the local shift toward cleaner power. Construction began in July 2024, and the 150-megawatt first phase went online in September 2025. This staged rollout allowed the capacity to grow steadily until the site reached full operation under the management of ContourGlobal. The project represents a shared effort between ContourGlobal and Platte River Power Authority to expand the reach of renewable energy solutions.

Beyond its contribution to the local grid, the complex stands as a technological milestone for the surrounding community. Its completion required the combined efforts of engineers, construction crews, and local officials, all working to bring the facility to life. The project also reflects a broader regional focus on lowering carbon emissions and adopting more sustainable energy practices.

By reducing the local reliance on fossil fuels, the facility supports a cleaner environment while providing economic benefits. The project has created jobs during its construction and will continue to do so throughout its operation, supporting the economy in Severance and nearby towns. The launch of the Black Hollow Sun Solar Complex provides a template for future large-scale solar projects in Colorado. As more communities look toward sustainable infrastructure, this facility demonstrates how utility-scale solar can be integrated into the existing energy network to help secure long-term energy independence.
