Doe appliances and commercial equipment standards program l.jpg

DOE – Appliances and Commercial Equipment Standards Program

  • Develops test procedures and minimum efficiency standards for residential appliances and commercial equipment

  • Applies to products manufactured for sale in as well as those imported into the United States


Laws and regulations l.jpg

Laws and Regulations

  • The Energy Policy and Conservation Act (EPCA) of 1975 established an energy conservation program for major household appliances.

  • The National Energy Conservation Policy Act of 1978 amended EPCA to add Part C of Title III, which established an energy conservation program for certain industrial equipment.

  • The Energy Policy Act of 1992 amended EPCA to add certain commercial equipment, including distribution transformers.

Doe actions on distribution transformers l.jpg

DOE Actions on Distribution Transformers

  • Determination Analysis

    • Oak Ridge National Laboratory, 1994-1996 White Papers

    • "Based on its analysis of the information now available, the Department has determined that energy conservation standards for transformers appear to be technologically feasible and economically justified, and are likely to result in significant savings" (October 22, 1997).

Slide10 l.jpg

The Energy Policy and Conservation Act directs DOE to take into consideration seven factors when setting energy conservation standards


Doe efficiency calculations l.jpg

DOE Efficiency Calculations

Efficiency = Power OUT/Power IN

%EFF = 100 x kVA x 0.5

kVA x 0.5 + ((NL + LL x 0.91x 0.52)/1000)

Where:

%EFF = Efficiency means the ration of the useful power to the total power input; for DOE Rule it is calculated at 50% Load

kVA = Transformer Capacity in kilo-volt Amperes

NL = No Load (Core) Losses corrected to 20oC

LL = Load Losses corrected to 85oC

0.091 = Load Loss Temperature correction from 85oC to 55oC


Slide12 l.jpg

Trial Standard Levels (TSLs) span levels from the voluntary industry standard to maximum technologically feasible.

  • Six Trial Standard Levels were considered:

    • TSL1 = NEMA TP 1-2002 (industry voluntary standard)

    • TSL2 ~1/3 of the efficiency between TP 1 and Min LCC (TSL4)

    • TSL3 ~2/3 of the efficiency between TP 1 and Min LCC (TSL4)

    • TSL4 ~minimum life-cycle cost (LCC)

    • TSL5 ~maximum energy savings with no change in LCC

    • TSL6 = maximum technologically feasible

  • Similar to the Candidate Standard Levels published in the ANOPR

  • On liquid-immersed, some TSLs slightly modified for consistency or for core steel grouping


Industry positions l.jpg

Industry Positions

  • DOE NOPR, NRECA T&DEC – TSL2

  • NEMA – TSL1 (NEMA TP-1)

  • EEI, APPA, Environmental Groups, ABB – TSL4

Legal actions l.jpg

Legal Actions

  • The State of California along with Sierra Club, and NRDC filed a lawsuit against DOE, claiming that it failed to follow the requirements of the National Environmental Policy Act

    • The States of New York, New Jersey, and Connecticut as well as New York City have filed to intervene on the side of California

    • NEMA filed to intervene on the side of DOE

  • NEMA does not anticipate a ruling before year end 2008

  • Consensus is that the current DOE Rules will be implemented as stated in 1/1/2010, with possible increased efficiencies to follow
