The Electrical System

The electrical power system is divided into generation, transmission and distribution. This system allows the PUD to provide safe, reliable and clean energy to more than 47,000 customer-owners.

1 GENERATION: 
In Chelan County, electricity is generated at one of the PUD's three hydroelectric projects: Rocky Reach Dam, Rock Island Dam, and Lake Chelan Dam.




Transmission2 TRANSMISSION: 
These hydroelectric projects produce high voltage power which travels via transmission lines to transmission switchyards, where electrical voltage is reduced by transformers. Electricity then travels along smaller transmission lines to distribution substations, where voltage is again reduced to levels that can be used by homes and businesses. 






NShoreSub2024_33 DISTRIBUTION: 
Power is delivered directly to your home or business via overhead or underground distribution lines. These lines carry electricity to pole-mounted (overhead) or pad-mounted (ground level) transformers, which reduce voltage yet again to a standard voltage level appropriate for your home or business.
