Summary of the Unitil Predictive Maintenance Program with Exacter (2012-2015)
Unitil saw that outages caused by equipment failure presented the best opportunity to improve overall system reliability. They began a program targeting all of their 3 phase circuits in 2012 that lasted through 2015. The results were so interesting that a full article was written and is featured in the October 2015 issue of T&D World Magazine, click here. To attend an informative "Case Study Webinar" of the Unitil Predictive Program, click here. Below is a summary of the first 3 years of this reliability program:
Overhead equipment failure accounts for about 20%
of Unitil power outages
Exacter predicted a 10% reduction in SAIDI and CMI before the program began
Reduction in SAIDI and CMI far exceeded Exacter's estimate of 10%
Power Outages have decreased
Outages occurring at any of the problem locations could have resulted in over 1 million CMI each year
Cost to conduct surveys was less than $250,000/year
Cost to replace problematic equipment averaged $50,000 per year
