Aging Substations: Practical Methods to Improve Structural Reliability and Enhance Resiliency

Wednesday, April 12, 2022 | 12:00 - 1:00 p.m. EDT

Our webinars are eligible for IEEE PDH credit. To qualify, you must attend the webinar live and complete the IEEE evaluation we will provide following the event.


Often overlooked, substation support structures are some of the most important assets on your system. They support hard-to-replace, high-lead-time equipment that is critical to system reliability. The possibility of an unexpected failure of these structures is alarming. The loss of a structure can threaten the integrity of the substation and potentially the stability of the local power grid.

Yet substation structures are, in some cases, as susceptible to corrosion as any other steel structure due to several contributing factors including location, design, and placement. Even though many substation structures are built on concrete foundations isolating them from the corrosive influence of soil, they often collect water and debris internally creating conditions that support corrosion activity.

Regular assessment of substation structures can identify structural deficiencies allowing for planned restoration. Whereas, restoration can return the structure back to its original or better strength while still in service in many cases.

In this webinar, we will discuss:

  • Fundamental components of substation structure assessments
  • Conditions that impact the reliability of substation components
  • Substation structure mitigations
  • Structure restoration methods
