Borrego Solar Systems Inc., a California-based solar power project designer, developer, installer, and operations and maintenance (O&M) provider, says that since expanding its O&M services to all owners of commercial- and utility-scale PV plants in early 2015, the company now has 265 MW of assets under contract. The current portfolio is more than double what Borrego Solar managed in 2014 and quadruple that of 2013. Prior to 2015, the company only offered its O&M services to PV system owners of the projects it designed and built. In 2015, the offering was extended to projects developed and constructed by other engineering, procurement and construction firms.
