Primergy Power

Primergy Power develops, builds, and operates utility-scale solar and battery storage projects across the United States. Its portfolio includes Gemini, described on the company's site as one of the largest co-located solar and storage projects in the country, along with projects in Texas, Arkansas, and Nevada. The company works through the full life of a project, from site selection and financing to long-term operations and maintenance.

This is a utility-scale developer rather than a service company for homeowners, so it does not take residential installation calls. Its partners include energy buyers, investors, landowners, and public agencies. The main office is in Oakland, and the company is a portfolio company of Quinbrook.
