Rebuilding 10 Substations in 10 Years

Most EWEB substations were built in the 1970s during a building boom that expanded EWEB service territory, putting many of our transformers over 40 years of age, even a few reaching 70 years old.

EWEB plans to address this aging bubble of infrastructure with 10 major substation rebuilds in the next 10 years that will increase load capacity to ensure we meet future needs and improve reliability by avoiding outages due to equipment failure.

Substation Rebuilds are Risk-based projects based on the age and condition of equipment. These types of projects make up 70% of the work in EWEB's 10-year Capital Improvement Plan. The order in which these projects are completed depends on the equipment’s expected end of life, to avoid running the equipment to the point of failure which may lead to customer outages. Risk-Based work provides more leniency in project selection and timing and is rooted in avoiding a future failure due to age or condition.  

Here's an overview of completed and upcoming substation projects:
