3 Regional Collaboration Effort Discussions in 2007 between BPA, ETO, PacifiCorp, PSE, Idaho Power, Tacoma, SnoPUD, SCL, others to explore opportunities to collaborate in the small compressed air market (<100HP). Meet monthly for 1 hour calls. Original Goal: “For small compressed air systems (less than 100HP) make the utility programs easier for vendor/trade allies to implement. Seamless from one utility’s service territory to another.” Decided utilities would work together on small CA information, tip sheets, CAC training (via IEA), analysis method, case studies, etc. Decided that incentive rates and structure are utility dependant. Cofunded market evaluation study by Cadmus (July08) -Cadmus study suggests over 10,000 small compressed air systems in PNW....however, very little attention or projects.

4 CADMUS Study - Participation “ Willingness to participate in potential efficiency programs is low, with 40% of market actors describing themselves as “not likely” to participate. The primary cause for this result is low perceived savings, which were not deemed commensurate with the time and resources required to participate.” pg 2, Executive Summary Time and resource requirements significantly reduced with current approach Savings values custom calculated for each job and presented with project economics

5 CADMUS Study – Vendor Involvement “ Vendors were consistently identified as the most important factor in the success of compressed air programs. Without educated and enthusiastic vendor support for energy efficiency, projects will not be submitted to the program.” pg 42 Spreadsheet tool supports the program concept of designing around vendor needs and desires

6 Why a small compressed air system analyis tool? Customer and Ally Perspective Minimal time investment –Limited application documentation –Vendor assistance with technical detail and no logging requirement allows on-the-spot information gathering Project economics presented –Customer can review project economics soon after initial consideration to allow an informed decision without having to spend additional time reviewing Uses existing end user contacts –makes use of existing vendor relations to limit number of contacts a customer must know –customer feels a compressed air specialist familiar with their situation is helping them –third party neutrality

7 Regional Small CA Tool Team agreed to use common tool developed by Cascade Energy Engineering Limit of 75 hp single compressor 2- Make a standard baseline for new units load/unload, not inlet modulation 3- “genericize” the tool so it can be used across multiple utility service territories 4- Add training requirements of trade allies before using the tool

9 Results to date

10 Results to Date – Compressor Size Average Size = 30.1 hp

11 Results to Date – Vendor Participation

12 Results to Date – Baseline Compressor Control Type 2/3 of projects 1/3 of projects 53% load/unload 47% inlet modulation 40% inlet modulation 60% load/unload

13 Results to Date – Relevant Averages Average savings/project, kWh: Average incentive/kWh: Average compressor size: Avg savings as % of baseline, kWh: Average system demand for air as percent of full load: 35,506 $ hp 39% 40%

14 Vendor Feedback “I’ll get out there and bring you some more projects!” “I totally think you guys have made a big step forward.” “Only about 2 of the 25 projects we brought you would have moved without this program.” “I have a customer not in your territory, but in _____. His compressor just went down. Can _____’s utility turn a project around as fast as you guys?”

15 Next Steps Approval by RTF Approval by Pacificorp and PSE Post tool on BPA and PTR websites Market tool to other allies BPA hire Cascade to train new users on tool Get more projects going!!! Collect M&V data (eg from run hours and total kWh from VFD machines) Report success to RTF (if warranted)
