With record levels of utility-scale solar and energy storage on the grid, financiers, developers and owner/operators must understand costs and benefits of Operations and Maintenance (O&M) and Asset Management to implement best-in-class models optimizing asset life, production, and return on investment. Never has the role of O&M and Asset Management been more important. 

Origis Services analyzed data from a total of over two gigawatts of utility scale solar and specifically the hours spent on corrective maintenance for 100 MW systems. The information is outlined in the Origis Services Solar Power International 2020 poster.

Combined with industry standard time studies and pricing models, the study demonstrated including roughly 70% of corrective maintenance into the annual service fee is the most effective way to reduce overall O&M costs for the asset owner.

Including corrective maintenance in the scope of service reduces the exposure to high-priced, dispatched services and provides additional benefits of dedicated plant personnel.  This strategy decreases the overall cost of O&M for asset owners by up to 28% or more and enhances the service-model stability of O&M providers, thus reducing the overall cost of O&M.
