ON Semiconductor to Host Energy Efficiency Test Procedure Workshop Sponsored by the California Energy Commission and U.S. EPA

Business Wire, Jan 18, 2006

PHOENIX -- Workshop gives electronics manufacturers developing and utilizing internal power supplies a final opportunity to voice comments before the test procedures are announced at APEC

ON Semiconductor (Nasdaq: ONNN) will host the workshop to discuss the final draft of the generalized energy efficiency test procedure for internal power supplies found in IT equipment, consumer electronics and white goods. This one-day technical session -- sponsored by the California Energy Commission and the U.S. Environmental Protection Agency (EPA) ENERGY STAR(R) program -- will be held on Jan. 19, from 8 a.m. to 4:30 p.m. at ON Semiconductor's corporate headquarters in Phoenix.

The final test procedure for measuring the energy efficiency of internal power supplies will be unveiled in March at the Applied Power Electronics Conference and Exposition (APEC) in Dallas. The new test procedure is the result of two years of research conducted by Ecos Consulting and EPRI Solutions, and funded by the Energy Commission's Public Interest Energy Research (PIER) program. Research has shown that modest efficiency improvements to internal power supplies offer an estimated potential electricity savings in the United States alone of 37.3 million kWh annually.

"The need for standard, accurate reporting of energy efficiency levels of internal power supplies continues to increase, especially as energy efficiency claims become an important market differentiator in a highly competitive marketplace," said Chris Calwell, Ecos Consulting's research director. "We encourage stakeholder participation to ensure all viewpoints are considered in the final test procedure."

The focus of the discussion at this week's workshop will be Draft Five of the internal power supply test procedure. (A copy is available at www.efficientppowersupplies.org.) This workshop will be the last opportunity for materially affected stakeholders to offer comments and pose questions in person about the procedure. Those unable to attend the workshop can, however, still participate the in the final development process by submitting comments to Peter May-Ostendorp, research analyst at Ecos Consulting at postendorp@ecosconsulting.com by Feb. 15, 2006. Comments will be summarized and posted to the Web site by March 15.
