as possible; however, some comparisons between BPA programs and 

 those of other utilities might be unfair. Frequently, the utility 

 programs compared are less comprehensive and less aggressive than 

 BPA's conservation programs. This does not mean that BPA's 

 conservation programs cannot be improved; there is ample evidence 

 that improvement is possible. We just need to decide what is broken 

 before we try to fix it.

Please provide an estimate of BPA expenditures to date on the Manufactured 

 Housing Acquisition Program (MAP) per fiscal year. What Percentage of 

 these expenditures were administrative costs? Please provide an estimate of 

 the percentage of MAP homes that are sited in areas currently served by 

 natural gas. 



• Historically, very few manufactured homes have used gas . Each 

 year, over 11,000 manufactured homes are sited in the region. More 

 than 90% of these homes are electrically heated. It is difficult to 

 accurately estimate the number of these manufactured homes that are 

 located where natural gas is available. 



• The regional benefits of MAP are significant . With energy savings 

 of approximately 6,000 kWh per year per house, the new homes 

 leaving the factory will add another 7.5 average megawatts of 

 conservation savings. The MAP is expected to save Northwest 

 consumers approximately $38 million over the term of the four year 

 contract.

Please describe the scope of BPA's activities regarding fuel switching. 



Bonneville and its customers reviewed the fuel choice policy as part of the 

 1992 Resource Program. The conclusions drawn from this review were 

 threefold. 



Fuel switching is a potentially cost-effective resource but the method and 

 rate of acquisition are unclear . Bonneville identified approximately 200 

 aMW of fuel switching resource potential not expected to be captured by 

 current market forces in the service areas of its customer utilities. What 

 was not clear from the analysis was how, if at all, this resource could be
