​Customer Billing
​BPA strives for accurate and timely bill preparation and issuance. Below are some resources to help with understanding your bill
New Customer Billing Center (CBC)
​On Feb. 1, 2010 Customer Billing implemented a consolidated Customer Billing system to produce both Power and Transmission bills. In August 2013 BPA started offering a combined Power and Transmission bill for Network and Full Service customers. If you are interested in receiving one, please contact your BPA Account Executive.

Total Transmission System Load (TTSL)
TTSL is an approximation of loading on any part of the BPA transmission system, based on federal and non-federal generation within the BPA control area, and interchange and wheeling onto the system.
