service in the economy energy market? (e.g., storage services.) 

 Unbundling services on these bases might lead to expanded supply of 

 scarce and valuable services, and customer provision of these services 

 where they can do so more efBciently or at lower cost. 



To date, BPA has not identified any services that could not be unbundled. 

 Since most of BPA's current costs are fixed and provided from an 

 electrically and hydraulically integrated system, identification of costs for 

 separate services involves assigning costs to different services fi'om a 

 common resource. While utilities have historically engaged in this exercise 

 in developing cost of service studies, there is no precisely right answer 

 about such assignments. 



With regards to examples of unbundled wholesale power services in either 

 the public or private sectors, Bonneville has yet to conduct such a study. 

 We will, however be initiating this activity in upcoming weeks.
