Rates and Tariffs

For the convenience of our customers, Cascade’s tariffs are made available here. The tariffs posted here are approved by the Washington Utilities and Transportation Commission (WUTC) and the Oregon Public Utility Commission (OPUC) and are the effective rates, rules and regulations of this company.

Cascade seeks to keep this information accurate and current, however, the official tariffs actually in effect, are on file with the respective regulatory Commission. Copies of the official tariffs are also available in each of Cascade’s business offices.

Any questions or comments regarding this information should be directed to the Regulatory Affairs Department at 509-734-4593.
