Discussion Topics

• Regional EE collaboration targeting opportunities
  in small compressed air systems.
• Why a small compressed air calculator?
• Demo of spreadsheet tool

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 (lt100HP). 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 utilitys 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.

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

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

Regional Small CA Tool

• Team agreed to use common tool developed by
  Cascade Energy Engineering...
• 1-       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

Vendor Feedback

• Ill 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?

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 MV data (eg from run hours and total kWh
  from VFD machines)
• Report success to RTF (if warranted)
