Energy Savings

1.58 quads over 30 years (2016-2045)

Eliminate the need for 2.4 GW of generating capacity by 2045

Cost Savings

Cumulative Net Present Value ranges from 2.9 billion (7% discount rate) to 12.1 billion (3% discount rate)

Environment Benefits:

CO2 emission reduction 122.1 mt

NOx emission reduction of 98.7 kt

Hg emission reduction of .819 ton

Notice of Proposed Rule – February 2012 Incremental savings

Percentage of 2007 designs that met 2010

1Φ - 47%

S3Φ < 750 kVA - 53%

L3Φ > 750 kVA – 59%

Percentage of 2011 designs that met the proposed 2016

1Φ - 44%

S3Φ < 750 kVA - 27%

L3Φ > 750 kVA – 7%

Impact to manufacturersPercent of designs meeting proposed ruling

Core steel availability of high performance steel to meet the demand

Potential capital and R&D investment if amorphous metal is required

May be forced to sole-source their core steel should amorphous metal be required

May be required to strand assets if new manufacturing processes are required

Refurbished transformers may be more attractive

Impact to manufacturersVoiced concerns

Increase in conductor cross section

Weights and dimensions increase

Transportation cost increase as less units per truck load

Average oil volume per unit increases due to wider & deeper tanks not being offset by reduction in tank height

Impact to manufacturer2016 proposed efficiency

Strong views by all

Against

Not enough

Acceptable


Impact to customers and end users

Substituting amorphous steel for RGO Higher costs

Only one supplier

Size and weight increases Polemounts

Vault and networks

Cost and payback Understated cost

Overstated savings

Driving away from successful A & B method


Impact to customers and end usersConcerns

Impact to customers and end usersPrice impact

M3 Electrical core steel can be used for complete range

Transformer ownership costCost capitalization formula

TOC or Capitalized Cost = Price + Cost of Losses

Price ($) = purchase price

Cost of Losses = (A x NLL) + (B x LL)

A ($/W) = Capitalized Cost of No-Load Losses

B ($/W) = Capitalized Cost of Load Losses

NLL (W) = No Load Losses

LL (W) = Load Losses

A & B Factors are unique to each purchaser of transformer even to their respective industry

Transformer ownership costA & B factors are still needed

Core loss or winding loss may not be lower

2010 2016

A & B factors still drive best design for individual customers

Publication of final rule - October 2012

Increases in efficiency expected for effective date of 2016

Ask questions specific to your transformers, changes in costs, weights, dimensions

Review your A & B factors for the real cost of operating transformers
