Owner’s Engineering

PRYSM offers Owner’s Engineering services throughout the lifecycle of a project. This allows our clients to continue their core business while we provide expertise in managing utility-scale solar projects from inception through operation. PRYSM’s Owner’s Engineering scope includes planning, design, procurement, construction, startup & commissioning and operations & maintenance.

While our services are designed to blend seamlessly throughout the project, we are flexible to provide only the services our clients need. Any of PRYSM’s services can be performed separately to compliment your in-house strengths to deliver the best value for the project.

Independent Evaluations

PRYSM utilizes our industry experience and proprietary energy modeling to provide independent evaluations for bankable reports to suit your financial needs. We will combine meteorological data with long-term solar reference stations and field measurements to accurately define the solar resource for your project. The resource assessment forms the foundation of the energy production projections and the independent evaluation report.

If you are looking to acquire an existing plant, PRYSM will perform a detailed surveillance of the facility to find potential factors that will impact the energy production forecast. Our surveillance includes a review of construction quality, maintenance records, and previous energy production. We also test select components to ensure they are functioning properly.

We deliver value every step of the way


PRYSM knows that successful projects are a product of thorough design and begin with extensive planning. The first step in our involvement is to provide a preliminary design for the project. This includes recommended manufacturers for key components and energy production projections. We also create project schedule and budgetary guidelines.


The engineering team at PRYSM reviews the project specifications and makes recommendations to improve the energy production forecast. We leverage relationships with industry suppliers to analyze the newest and best technology for your project. As the design progresses, we update the energy production projections to accurately forecast the value of the project.


Starting with RFQ development, PRYSM manages the entire procurement process. We host pre-bid meetings, perform a complete bid evaluation and negotiate the award of the contracts. After award, PRYSM provides contract administration, supplier qualifications, audits, expediting and project controls monitoring until the contract is closed.


PRYSM provides construction management and safety and quality program oversight during the construction stage of a project. We perform ongoing surveillances and audits for quality assurance, monitor the EPC contractor’s schedule and budget, and implement recovery plans when necessary.

Startup & Commissioning

The PRYSM team has extensive experience commissioning solar power plants. We ensure the EPC contractor adheres to industry-accepted testing procedures. We provide third-party verification of testing results, and draw from our experience to troubleshoot and resolve problems to maintain the committed COD date.

Operations & Maintenance

PRYSM supports ongoing needs through operations and maintenance agreements. We optimize preventative maintenance schedules in order to minimize the impact to energy production and reduce the owner’s costs.
