Puget Sound Energy substation project
Ardmore substation
Summer 2010 project updates
- Puget Sound Energy has selected our preliminary preferred site
- We plan to file permits in the fall of 2010
- Construction is expected to begin in summer 2011
Project Overview
PSE needs to build a new substation and extend and reconfigure existing transmission lines to meet increased demand for electricity in the South Redmond/Northeast Bellevue area. The Ardmore substation will increase system capacity to accommodate future growth and improve the reliability of the electrical system. Extensive residential and commercial growth in the South Redmond/Northeast Bellevue area has resulted in the electrical load approaching the capacity of existing substations and transmission lines. In addition, the cities of Bellevue and Redmond plan to significantly increase land use densities in the Bel-Red corridor and Overlake area. In 2009, PSE selected and purchased a new site for the substation, located at 2245 Northeast Bel-Red Road in Redmond.
What is a substation?
Substations are critical links in the electricity distribution system, containing utility circuit protection, voltage regulation, and equipment that steps down higher voltage to lower voltage. Before reaching homes and businesses, power is routed through our transmission system to a substation where it is changed to a lower voltage that can be utilized by customers.
What is a transmission line?
Transmission lines are key elements in the electrical distribution system. The lines safely transport high voltage electricity from power generation sources like dams and wind generating facilities to substations in local communities. Transmission normally takes place at voltages of 55 kV and higher.
Committed to keeping you informed
PSE will continue to provide updates to the community. We will notify residents and businesses near the project area when construction will occur. We aim to complete the work with as little disruption as possible.
