Distribution substations are an important part of the electrical system
that provides sustainable, reliable power to customers throughout Chelan County. Substations reduce high-voltage electricity (transmission) to low-voltage electricity (distribution) for residential and commercial use. The PUD has 35 distribution substations located strategically throughout our service territory – in rural, commercial, and residential areas. A substation typically serves approximately 1,500 residential homes.
Responding to Growth
As energy demand grows, the PUD needs to build new infrastructure to serve that growth. Learn more about growth forecasting and infrastructure planning here
Generally, we will identify the need for a new substation when the existing substation serving an area approaches 80% capacity. Once the need for a new substation is identified, it can take from 3 – 5 years to site, design and construct the facility so it can serve the growing power demands.
