  1. Ultra-Premium Efficiency Motor Standard Protocol Recommendation Regional Technical Forum November 19, 2013

  2. Presentation Outline • Staff Highlighted Areas • Measure Definition • Measure History • Regional Interest • RTF Decision Photo from www.ebay.com

  3. Staff Highlighted Areas • Measure deactivation • Staff recommends deactivating the current RTF deemed calculator and stopping development of a standard protocol due to: • A lack of regional interest in the measure; • Data deficiencies that would require either interest in a provisional standard protocol or additional staff time to rework protocol as a ‘small saver;’ and • Staff time and budget considerations (i.e., is it worth it to continue working on this?)

  4. Measure Definition • Installation of an ultra-premium efficiency motor in place of a baseline motor • Applies to “general purpose” motors between 1 and 500 HP • Baseline motor is defined as the NEMA Premium efficiency standard in the 1-200 HP range, and the average EPAct motor efficiency in the 250-500 HP range • Ultra-premium efficiency motors must have a nominal efficiency at least one full NEMA band higher than the base NEMA Premium efficiency

  5. Measure History • June 2003 – Premium Efficiency Motor Deemed Calculator adopted by RTF • Feb. 2011 – Premium Efficiency Motor Deemed Calculator put under review due to updated federal standards • Nov. 2012 – Cascade Energy presented Ultra-Premium Efficiency Motor Standard Protocol and calculator to replace current calculator • RTF questioned ability to use default tables for motor load factor and operating hours • RTF voted to delay action on protocol / suggested protocol could be a “small saver”

  6. Regional Interest • Reached out to BPA about interest in the protocol • BPA staff pointed to current issues surrounding ultra-premium efficiency motors in the market: • Motor manufacturers pushing back against ultra-premium motor rebates due to high production costs (e.g. costs of re-tooling, “super-alloy" materials) • Manufacturers concerned rebates will drive further motor standards and thus increase costs

  7. Regional Interest (continued) • As a result, NEMA and ACEEE have formed a national working group to develop standards for rating motor systems • NEEA, ETO, and BPA are all participating in the working group • Other market issues have been raised • Motors entering the market from overseas with no standardized efficiency testing, but receiving a nameplate rating equivalent to ultra-premium

  8. Regional Interest (continued) • Reached out to other utilities to gauge interest in continuing the development of the protocol: • Avista, PacifiCorp, PSE • Avistaand PacifiCorp indicated they were not interested in further development (along with BPA)

  9. RTF Decision “I _________ move that the RTF deactivate the current RTF Premium Efficiency Motor deemed calculator and stop development of a standard protocol.”
