The purpose of this commissioning guide is to provide general guidelines, best practices, and typical reference procedures to assist engineers in understanding, planning, and carrying out the commissioning of auxiliary systems and equipment for hydroelectric stations. In addition, this guide is also meant to assist operational staff in understanding commissioning requirements. The objective of a commissioning program is to ensure that all equipment can be operated safely and reliably as an integrated assembly, as required by the design specifications and performance requirements. This is achieved by performing a series of carefully planned tests and assessing the results.

This commissioning guide seeks to assist hydroelectric plant commissioning staff, plant owners, operational groups, and contractors in developing and resourcing a plan for the orderly and sequential testing of the auxiliary systems and equipment at the end of the construction (or refurbishment) phase of work. Carrying out a successful commissioning plan ensures that the equipment is ready for acceptance and eventual transfer to the station owner/operator for normal and reliable commercial operation.

This guide covers auxiliary systems for hydroelectric facilities without considering major water-to-wire equipment.
