Staff Highlighted Areas 3 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?)

Measure Definition 4 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 HP range, and the average EPAct motor efficiency in the HP range – Ultra-premium efficiency motors must have a nominal efficiency at least one full NEMA band higher than the base NEMA Premium efficiency

Measure History June 2003 – Premium Efficiency Motor Deemed Calculator adopted by RTFPremium Efficiency Motor Deemed Calculator Feb – Premium Efficiency Motor Deemed Calculator put under review due to updated federal standards Nov – Cascade Energy presented Ultra- Premium Efficiency Motor Standard Protocol and calculator to replace current calculatorUltra- Premium Efficiency Motor Standard Protocol – 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” 5

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 6

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 7

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

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