Puget Sound Energy is investing approximately $421 million in service-area infrastructure improvements in 2008, of which about $247 million is earmarked for capacity and reliability upgrades, and about $174 million is allocated to meet growing customer needs.
PSE’s 2008 electric system investments include:
• Building four miles of new 230 kilovolt (kV) transmission line and five miles of new 115 kV transmission line.
• Replacing old power lines with new power lines along 54 miles of PSE’s transmission system.
• Replacing or injecting with silicone (to extend the life of cable) approximately 70 miles of underground cable.
• Replacing 800 poles.
• PSE’s 2008 natural gas system investments include:
• Installing approximately 200 miles of new natural gas main, including replacing approximately 20 miles of older, uncoated steel main.

The project in Redmond is the Novelty substation and electric transmission line. This project includes building a new transmission line between Northeast Novelty Hill Road and Avondale Road Northeast on PSE’s existing transmission line corridor at an estimated cost of $8.4 million to increase reliability and meet additional demand resulting from ongoing growth in Redmond and east King County. Anticipated completion: spring 2009.
