Case Studies on Energy Efficiency:

A6118: Mineral Producer Installing 150 Copper-Rotor Motors Rising Energy Costs Drive Upgrades, Rapid Payback Expected: This New York State mining concern decided to fight increasing utility charges by going beyond premium motor efficiency, long before the law required the change. 150 new cast copper rotor motors are being installed in place of both NEMA Premium and EPAct-efficiency motors.
(4 pgs.) 1 free (add’l $0.25 ea)
A6106: Shaw Industries Demands NEMA Premium^® Efficiency Motors for Savings, Reliability: The world's largest tufted broadloom carpet manufacturer specifies NEMA Premium motors where applicable; but their requirements for special purpose motors also means the highest efficiency possible where NEMA Premium doesn't apply.
(6 pgs.) 1 free (add’l $0.25 ea)
A6105: Bryant University Saves Energy Cuts Costs With All-Copper Systems: This R.I. university not only demands high efficiency motors, but has lowered operating costs and increased reliability by specifying copper-only wiring and high efficiency copper-wound transformers.
(6 pgs.) 1 free (add’l $0.25 ea)
A6100: Transformer Manufacturer Uses Only Copper: Copper is a very small part of the initial cost of a transformer. Pennsylvania Transformer Technologies points to the smaller size per kVA, allowing less lamination steel (meaning less no-load losses), less insulation, less oil, smaller heat exchangers, etc. Combined with high reliability demanded by their customers, copper is a better choice for winding material that provides OEM's with easier assembly and better manufacturability, and their customers with lower life cycle cost.

A6101: Copper and Wind Energy: Partners For a Clean Environment: Wind energy is growing at a very fast pace due to increased interest in renewable resources as the cost of fossil fuels rises, and copper plays a vital role in making that happen. Austin Energy is one utility that is taking dramatic steps to ensure that wind, and other renewables, are a big part of their energy mix.

A6030: Energy-Efficient Transformer Yields 156% ROI: By applying life-cycle cost analysis, Herman Miller, Inc. achieved a seven-month payback period on the incremental cost of purchasing the most efficient transformer for their facility. Their Green Building/Facility Design Group uses lowest-total-owning cost analysis to reduce energy costs throughout the company. The practice can help your company also.

A6089: Brass Mill Cuts Costs with NEMA Premium^® Motors: At one of the nation's largest brass mill, if a 50-hp (or smaller) motor fails, it's replaced with NEMA Premium. If it's larger and the cost of a repair or rewind is 50% or more of a replacement, a new motor is purchased. That policy is ensuring 18-month, or less, payback for Outokumpu Copper Products. See how this motor plan, along with copper-wound transformers, can help your company.

A6092: Kodak Focuses on NEMA Premium^® Motors: A world leader in photography, Kodak is also a leader in adoption of NEMA Premium motors. With over 70,000 motors in operation at any given time, Kodak has adopted a "Total Motor Program" that specifies NEMA Premium or better efficiency every time a general purpose motor of 20 hp or below fails, and evaluation for replacement above that threshold. Kodak has already saved over $250,000 per year in energy costs, and reduced emissions in the process, while increasing reliability.

A6090: Skating Arena Cuts Energy Costs with Premium-Efficiency Motors: One would not imagine part time use and only a 28% duty cycle would be a typical application for high efficiency motors. Yet, despite this low duty factor, replacement of older, but perfectly functioning, standard efficiency motors with NEMA Premium^® models did produce a 4-month payback for a New England arena.

A6080: Weyerhaeuser Policy Calls for Premium-Efficiency Motors and Transformers: If you’re going “green,” do it right. In 1995, Weyerhaeuser established a company-wide policy to reduce energy consumption and costs and to minimize the impact of its huge power requirement on the environment. Replacement of 2,800 motors per year and another 525 upgrades per year to the best motors available actually reduces their total cost of ownership and increases the reliability and service life of their equipment.
