Automating the Nisqually Project: Tacoma Power's Upgrade Experience

摘要

During a recent rehabilitation effort, Tacoma Power replaced the automation systems at its two-powerhouse 114-MW Nisqually project. As a result of this work, Tacoma Power cut unit start-stop times in half, eliminated 24-hour on-site operators, and established a process to store and trend plant data. Designing and installing the automation system in-house let Tacoma Power maintain control of the technology and ensure the system met all its requirements.
