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?)

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

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”

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– Avista and PacifiCorp indicated they were not

interested in further development (along with BPA)

RTF Decision

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