Pima County Success Story
The data-mining capabilities of the SCADA system’s Wonderware Historian application produced detailed documentation, which enabled the County to receive a $352,000 rebate check from the local utility.
“Being able to access detailed data from the Historian allowed the Regional Wastewater Reclamation Department (RWRD) to analyze our electrical usage and determine that we could save more than $200,000 a year on a time-of-use electrical rate,” said Eric Nelson, technical services manager at Pima County. “The preliminary analysis would have been impossible to do without the Historian and we would have missed a huge opportunity to reduce our service costs to our ratepayers.”
