  1. Agriculture Irrigation HardwareUES Measure Update Regional Technical Forum April 16, 2013

  2. Agriculture Irrigation Hardware Measure Overview • Current Category: Proven • Current Status: Out-of-Compliance • Current Sunset Date: April 2013 • Reason for Update/Review: Follow-up to OOC plan; and sunset date • Subcommittee Review: Yes - Ag Irrigation Subcommittee (notes)

  3. Measure Descriptions • Go to the following sections in the Summary tab in the proposed measure workbook: • Measure Properties • Measure Identifiers

  4. Summary of Updates • Changed measure category to “Small Saver” • Professional judgment is used • Recent regional program savings estimated at 1.0 – 1.5 aMW per year. • Incorporated data from recent studies: • Idaho field study (Neibling) • PacifiCorp program data (2006-2008; 2009-2011) • Most recent Farm and Ranch Survey • Measure Additions/Changes • Added a new measure: Tower Gaskets. • Combined the existing Nozzle measure, Low Pressure Regulator measure, and sprinkler head measures (5) into a new “sprinkler package” measure. • Changed measure specification to require the following components to be leaking: • Wheel/hand line: Impact Sprinkler, Gasket, Drain, Hub, Leveler (also malfunctioning) • Pivot/Linear move: Pivot boot gasket, (Tower gasket, too) • Reviewed these updates and all other inputs with subcommittee and made some edits, with consensus.

  5. Remaining Issues for RTF Discussion • Subcommittee members may have additional comments • We had just one subcommittee meeting, so subcommittee members wanted to reserve the right to bring up any remaining issues after they had a chance for a more thorough review (up to the day of the RTF meeting: today).

  6. Measure Analysis and Inputs Details • Go to the following sections in the Summary tab in the proposed measure workbook: • Constant Parameter • Energy Savings Estimation Method, Parameters and Data Sources • Measure Incremental Costs and Benefits • Measure Lifetime

  7. Summary of Changes • Savings • Gaskets, Drains, and Leveler increased significantly • Pipe Repair increased by 50%-100% • All other measures increased or decreased slightly. • Cost • No changes (except combined Sprinkler Package costs and added Tower Gasket measure cost) • Life • No changes • TRC Cost-Effectiveness • Drains and Levelers are now cost-effective • The new combined Sprinkler Package measure is cost-effective • The new Tower Gasket measure is cost-effective only in the Eastern Washington and Oregon region • Go to the Presentation tab in the proposed measure workbook for graphs of existing vs. proposed savings and TRC.

  8. Subcommittee Proposal • Approve the updates to the agriculture irrigation hardware UES measure; • Change the measure category to “Small Saver”; • Set the measure status to “Active”; and • Change the sunset date to April 2018.

  9. Decision “I _______ move to approve the updates to the agriculture irrigation hardware UES measure; change the measure category to “Small Saver”; set the measure status to “Active”; and change the sunset date to April 2018.”
