Sundance Power Plant is typically operated with a minimal staff which presents problems with scheduling calendar-based vibration monitoring. Routes were often cancelled due to non-operation of the generating units or staff scheduled for other work. The calendar-based route was not providing the data needed to manage the plant’s assets. This situation was exacerbated when APS entered a new power market in October of 2016. Entry into this new market resulted in much more frequent operation of the generating units. The plant suffered numerous critical equipment failures that could have been prevented if scheduled vibration monitoring occurred. The solution was to implement a wireless vibration monitoring system that did not require plant staff to gather the data.
