  1. RTF Pump VFD Provisional Standard Protocol Regional Technical Forum June 18, 2013

  2. Presentation Agenda • Review Pump VFD Standard Protocol document • Summarize subcommittee feedback • Update the RTF of changes made to the document • Review Pump VFD Research Plan • Summarize subcommittee feedback • Walkthrough Pump VFD Calculator

  3. Pump VFD History • Began effort in March, 2012 • SBW contracted to develop Protocol and calculator specifications • Nexant contracted to develop working calculator based on protocol and specs • Cascade contracted to provide QC and market assessment • 5 Subcommittee meetings held from March, 2012 – June, 2013

  4. Pump VFD Provisional Standard Protocol Subcommittee Feedback • General agreement that the protocol as constructed, is applicable to enough potential projects to merit provisional standard protocol status. This is corroborated by the report: “Estimate of potential market for proposed pump VFD protocol – Cascade Energy” • Protocol expanded to include transfer pumps with on/off controls in the baseline period, as per subcommittee recommendation. • Staff proposed minor changes to improve document flow and add clarifications – subcommittee approved these changes. • Document presentation

  5. Pump VFD Provisional Research Plan Subcommittee Feedback • To calculate a sample size, expected variance between Best Practices (BP) and Simplest Reliable Method (SRM) is necessary, but unknown. • This is necessary to calculate a sample size with an estimated confidence and precision that meet guidelines. • As per the guidelines “The SRM can be validated if either (a) it is free from substantial bias and agrees (+/- 20%) with the BPM at the individual site level; or (b) it is free from substantial bias and agrees (+/- 10%) with the BPM, on average, with 90% confidence” • Proposed solution: Collect data from a minimum of 20 sites to understand population characteristics. • Once this data is analyzed, informed decisions regarding sampling can be made. • We propose a sunset date of June, 2015 to allow for data collection and analysis. • Document presentation

  6. Pump VFD Provisional Calculator Feedback • Calculator computes and compares savings from the BP and the SRM for each project • The calculator is currently in final stages of development. • First round of QC conducted by Cascade Energy and RTF staff • Staff implementing improvements and additions identified through QC • Staff developing the calculator to be more user friendly (help, instructions) • Calculator shall be expanded to include transfer pumps with on/off controls in the baseline period as per subcommittee recommendation • Calculator Presentation. • Next steps: • Cascade Energy QC • Calculator posted for subcommittee review

  7. “I _________ move that the RTF approve the provisional Pump VFD Protocol, Research Plan, and Calculator with a sunset date of June 30th, 2015 provided that the calculator conforms to the Protocoland passes QC review.”
