Puget Sound Energy electric transmission project
Bellingham area substation and transmission line upgrade
Winter 2009 project complete
- Puget Sound Energy completed a $6 million electric system upgrade to improve reliability and increase capacity in the Bellingham area on Dec. 10, 2009
- The project included upgrading the Old Town and Bellis substations and converting the Roeder and Lehigh substations, as well as parts of the Bellingham substation
- PSE will remove the aged transformers from the Bellingham substation as early as 2011
PSE has upgraded our existing low voltage 55 kilovolt (kV) substations and transmission lines to our now current standard of 115 kV to increase reliability and meet growing customer demand for power in the Bellingham area. The project entailed converting four substations and one commercial customer substation, rebuilding parts of Bellingham substation, and converting all of the transmission lines connecting the substations to 115 kV.
The $6 million dollar construction effort included the following transmission line and substation work:
- Bellis substation (4188 Northwest Dr.): Replaced transformer, updated equipment, modified transmission line terminations and loop the new 115 kV line.
- Old Town substation (F Street & Roeder Avenue): Replaced circuit switches, installed PSE communications, updated equipment and modified transmission line terminations.
- Roeder substation (2810 Roeder Ave.): Replaced circuit switches, updated equipment, modified transmission line terminations.
- Lehigh substation (near Marine Drive.): Updated equipment and modified transmission line terminations.
- Bellingham substation (2211 Nevada St.): Updated equipment and modified transmission line terminations for two transmission lines.
- Bellingham substation: Remove aged transformers
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.
