NV Energy partnered with Novinium for a cable injection pilot program and continues to use cable injection to increase system reliability. In the pilot program, cables were targeted in an area known to have a high number of cable failures. These cables were injected and monitored while the cable injection program was in its experimental stages during the initial years. However, even after the initial pilot program, it was apparent that the program was heading in the right direction with no faulted segments recorded in the treated areas.
To date, NV Energy has recorded less than 1% of injected cables faulting after they’ve gone through the injection process. Total success is measured over many years, but initial reliability improvements and process confidence resulted in NV Energy deciding to gradually increase its investment in this program with a current program budget of $12.5 million annually.
