  1. Plans to bring Out-of-Compliance UES Measures back into Compliance:1. Agricultural Irrigation Hardware UES2. Agricultural Motors UES Regional Technical Forum September 18, 2012

  2. Background • Ag Irrigation Hardware UES and Ag Motors UES • Out-of-Compliance on February 1, 2011 • Opportunity to bring in a plan extended to November 14, 2012. • Today we’re looking for RTF review (and approval?) of the plans to bring these two UES measures into compliance with the guidelines.

  3. Measure Description - Ag Hardware • 18 measures: Note: Those in blue with an asterisk were recommended as “under review” in the memo, but the RTF assigned them all out-of-compliance.

  4. Why Out-of-Compliance? (memo) Ag Irrigation Hardware • Savings calculated using subcommittee estimates for key baseline and efficient-case input parameters • Average Lift, Average System Pressure, “Baseline Factor”, Pump Efficiency, Motor Efficiency, Operating Hours, Pre/Post Flows and Leakage Rates • Need measured data to support baseline and efficient-cases.

  5. Proposed Plan – Ag Hardware Schedule • December 2012 – The following data submitted to subcommittee • The “Idaho Power / University of Idaho” field research • Final report due in December • BPA Pump Test Data compiled and provided(?) • Rocky Mountain Power • Data set for field data from 2009-2011 irrigation program participants available this fall • Date set from field work for 2006-2008 program impact evaluation. • January 2013 – The subcommittee will work to incorporate the findings into the UES savings. • February 2013 – Subcommittee will present its recommendations to the RTF. • Depending on study findings, this may include a mix of Proven, Provisional, and Small Saver measures.

  6. Proposed Plan – Ag Hardware (continued) Details of the Idaho Power / U of I Study(SOW) • Study Objective: Field data collection necessary to determine energy savings on irrigation hardware measures. • Approach: • Determine ratio of worn to non-worn components and degree of wear • Conduct water application uniformity tests • Measure volume of leaks • Determine age of equipment BPA Pump Test Data(Pump Test Data Collection Form) • BPA to provide Overall Plant Efficiency data from its pump tests • ??? Availability of the data unknown, but over 2,000 tests have been performed. Rocky Mountain Power Data • Flow (short term measurements), pressure, real power (short term measurements), well depth, crop data, billing records.

  7. Decision • Motion: The RTF approves the plan to bring the Ag Irrigation Hardware UES measures back into compliance with the Guidelines.

  8. Measure Description - Ag Motors • Replacement of existing ODP or TEFC motors 5hp or greater with premium efficiency motors.

  9. Why Out-of-Compliance? (memo) Ag Motors • Needs an empirical basis for: • hours of operation, • baseline motor efficiency, and • average loading.

  10. Proposed Plan – Ag Motors Two Options A. Deactivate this measure • Three utilities expressed little to no interest in the measure • Idaho Power • Not currently offered as a deemed measure (usually comes in with custom measures) • Would consider offering it if RTF-approved, but don’t expect big uptake • Rocky Mountain Power • Not currently offered as a deemed measure • “Lukewarm” on the measure • BPA • Measure was removed from deemed offering in October • Wasn’t a large measure (maybe 10 units came in when offered) B. Undertake the Proposed Plan…

  11. Proposed Plan – Ag Motors Data Collection • Hours of Operation • The following sources will be used to justify hours of operation: • Idaho Power to provide total kWh divided by peak kW (July) for irrigation customers. This value is inherently low, so will serve as the lower end of the possible range. • Ag Extension agency crop needs data will be used to determine typical annual water requirements by crop. Hours will be determined using the standard 7gpm/acre design criteria, and weighted by crop type. • Baseline Motor Efficiency • Motor manufacturers will be asked to provide their 20-year old product data. • Average Loading • The following sources will be used to justify motor loading: • Idaho Power will perform research using AMI data (to determine motor kW) and motor horsepower database to determine average loading on 100 motors. • BPA (still need to verify availability)will provide motor loading data from its many pump tests in the Region.

  12. Proposed Plan – Ag Motors (continued) Schedule • Assemble data by Jan 2013 • Subcommittee review in Jan 2013 • Proposal to RTF for Feb 2013 meeting • Depending on data collection results, revised measures may be proposed as Proven, Provisional, or Small Saver.

  13. Decision Motion Either: • Option A: The RTF deactivates the Ag Motors UES measure. Or: • Option B: The RTF approves the plan to bring the Ag Motors UES measures back into compliance with the Guidelines.
