Cable Rejuvenation Changes the Course of History at NV Energy: An In-depth Case Study

For the past 22 years, cable rejuvenation has played a key role in NV Energy’s (NVE) delivery of reliable electric power to its customer base of over 1.3 million homes and businesses in the United States’ desert southwest. Since the beginning of the program in 1998, more than 12 million conductor feet of their underground residential distribution (URD) system have been successfully rejuvenated by silicone fluid injection. This paper will explore the evolution of NVE’s reliability program from trial phase to the present and the metrics used to gauge the success of silicone fluid injection. Furthermore, the application of predictive modeling as a tool for forecasting future outages and estimating outages saved will be defined.
