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 2

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 3

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 4

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 5

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 6

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