Commissioning is the systematic process by which a piece of equipment, system, or facility is tested to verify that it functions in accordance with the design intent and owner's operational requirements.
In the past, the primary focus of commissioning has been on HVAC systems, but because of the need for increased electrical system reliability and complexity, owners are now starting to realize the importance and benefits of commissioning on-site electrical systems.
Some of the advantages include:
- Electrical systems that meet the operational needs of the owner
- Reduced downtime due to power outages caused by utility loss and/or failures within the electrical system
- Coordinated electrical systems that balance protection with reliability and meet the recent code requirements and standards for critical facilities
- Confidence that the electrical systems will operate correctly when required
- Knowledge of and experience with the operation of the electrical equipment.
Many share a common perception that commissioning is the final stage of a project, performed when a facility is complete or nearly complete. This perception is not true. Commissioning is a process, and in order to maximize commissioning success, it must begin in the pre-design phase of a project and continue through construction until that final verification is executed.
