Utility Proactively Tests Underground Cable

testing1

Distribution companies are continually looking for ways to improve system reliability, all while conserving capital investments and operational costs. With an aging infrastructure, one of the main issues that utilities face is a way to assess the actual condition of their capital assets.

With respect to underground cables, utilities can achieve enhanced reliability by developing a smarter asset management strategy. Historically, utilities used a reactive-based maintenance approach: when a cable fails, have it replaced. However, with increasing proportions of cables approaching end of life, this method is not sustainable because it consumes a significant portion of the operation and maintenance budget.  Simply put, for most utilities, not enough capital dollars are available to replace all of the aged cables. For this reason, utilities must employ an effective strategy to adopt condition-based maintenance to balance this issue.

Many utilities have switched to condition-based maintenance programs to more efficiently spend their capital budgets. Generally, utilities diagnose the health of a cable based on its age, and they expect cables to last 25 to 30 years. The age of a cable, however, is not always an indication of the cable’s quality.

Utilities Bank on IoT for Network Reliability Improvement to Decrease Lost Revenue

IoT

Power grids around the world are getting smarter thanks to the Internet of Things (IoT). While Smart Grid technologies are making the headlines, and poised to grow to more than $118 billion by 2019, according to November 2015 research from analyst firm Transparency Market Research—many utilities just aren’t ready to make the jump to full Smart Grid capabilities. In many cases, it’s the smaller improvements and IoT implementations in addition to larger-scale Smart Grid deployments

Using Transformer Monitoring Via the IoT to Combat Electricity Theft

Theft

According to the annual Emerging Markets Smart Grid: Outlook 2015 study by the Northeast Group, LLC, the world loses US$89.3 billion annually to electricity theft, with the top 50 emerging market countries losing $58.7 billion annually compared with $30.6bn in the rest of the world, including the largest industrialized economies.

In one of the more widely publicized cases recently, B.C. Hydro in Canada estimates that it was losing about 850 gigawatt hours per year due to electricity theft, that equates to more than $500 million in electricity, according to the company’s website.

As we see the electrical industry advance it is obvious the demographics will be challenged. The infrastructure investment needs of the electrical and renewable energy grid will reach the $billions$ over the next 15-20 years with expensive, complex and specialized training and education needs.  Technological advancements will have an impact on the skills required by the workforce, as well as the curriculum and programs developed by colleges and universities.
