1. Review Tabled Agenda Item: Additional M&V Data on Ag Pump VFD Projects Determination of M&V requirements and/or deemed savings Regional Technical Forum August 4 th, 2009

2. Background: July RTF Meeting BPA requested a deemed savings number for VFD’s in agriculture pump applications. BPA thinks a deemed number would encourage more projects since the current M&V requirements deter many projects. BPA Data: Proposal: Deem savings at 500 kWh/year/hp Issues Raised by the RTF – Operating hours vary based on crop type, weather, etc. – Not a lot of data to base a deemed savings from – Data do not show a linear relationship between savings and pump horsepower Meeting Conclusion: Table the issue until we see PacifiCorp’s project data

3. PacifiCorp’s Data # Pump Size (HP) Annual kWh Savings Annual kWh Savings per hp 130071,114237 220026,871134 325084,296337 410000 530036,947123 630076,987257 78537,207438 825032,505130 930077,674259 1012535,929287 11603,17853 127510,549141 Totals2345493,257210

4. All Savings Data

5. Cost Data

6. Recommended Options Option 1: Use data to generate a deem savings table for pumps 500 hp and less. – Allow all projects to claim the deemed savings value, based on pump size rating. – Pumps less than 25 hp do not qualify and pumps greater than 500 hp require M&V. Require pre and post M&V on 20% of the projects (selected randomly). Revise deemed savings estimates in 2 years, based on M&V data. Option 2: Do not deem energy savings at this time – If interest, RTF will review M&V data again in 2 years for merits of deeming Continue to require custom project M&V Note: Preliminary estimated 6 th Plan cutoff for cost-effectiveness is about 60 to 70 mils/kWh for non-lost-opportunity measures.
