1.1 What are the key issues for your company regarding the distribution transformer energy conservation 

standard rulemaking? 

1.2 How significant are the above key issues at each Trial Standard Level? 

1.3 How can we most effectively incorporate these issues in the Manufacturer Impact Analysis? 

2. COMPANY OVERVIEW AND ORGANIZATIONAL CHARACTERISTICS

The Department’s interest concerning manufacturer impact is focused at the plant or profit center level 

directly pertinent to transformer production. However, the context within which the plant operates and the 

details of plant production and costs are not readily available from the published literature, so the 

Department invites you to provide these details confidentially in your own words to the extent practical. 

The organizational setting around the transformer profit center is of interest to round out the Department’s 

understanding of the probable future of the transformer manufacturing activity with and without energy

efficiency standards. 

2.1 Do you have a parent company, and/or any subsidiaries relevant to the transformer industry? 

2.2 Where are your production facilities located, and what is the product mix manufactured at each 

location? 

2.3 What are your employment levels at these facilities?

2.4 What are your product lines, niches and relative strengths in the liquid-immersed market? 
12A-3

3. FINANCIAL PARAMETERS 

Navigant Consulting has built a model of industry financial impacts called the Government Regulatory 

Impact Model (GRIM), using publicly available data on distribution transformer manufacturers. This 

questionnaire attempts to understand how your company’s financial situation differs from our industry 

aggregate picture.

3.2 How might new efficiency standards alter your company’s financial parameters? 

4. MORE EFFICIENT DESIGNS 

The Department’s engineering analysis models improvements in efficiency by considering alternative 

combinations of design factors such as core steels, winding conductors, and joint configurations. The

Department would like to understand what changes may be necessary in your product designs for the 

production of higher efficiency liquid-immersed distribution transformers. 
12A-4

4.1 What are your current design features? For each design line, which materials are used to build your 

non-evaluated transformers? What joint types are used? 

4.2 Does your company build TP1-compliant transformers? How do these designs compare to your nonevaluated transformers? 

4.3 Does your company build transformers that significantly exceed TP1 efficiency levels? Which designs 

are used to exceed TP1? Which designs would you likely use to meet the various TSLs? 

4.4 Are there any other manufacturing issues that DOE should be aware of in terms of producing more 

energy efficient transformers at your facility? 

4.5 Do you currently fabricate your own cores and coils? Would the standard level change your business 

practices with respect to such make vs. buy decisions? 

5. MATERIAL PRICES AND AVAILABILITY 

5.1.In its revised Engineering Analysis, the Department updated its price assumptions for material inputs.

The Department considered two price scenarios: 1) 5-year average for the years 2000-2004 (2004 

US$), and 2) typical first quarter 2005 prices. The prices assumed to be paid by transformer 

manufacturers are shown in the table below. In your experience are these prices representative of the

industry as a whole? Are the prices that your company pays significantly different? If so, does this 

confer a disadvantage to your firm? 

Item and Description Material Price 

(2000-2004) 

Material Price 

(Q1 2005) 

M2 core steel $0.95 $1.71 

M3 core steel $0.80 $1.63 

M4 core steel $0.76 $1.56 

M6 core steel $0.70 $1.42 

ZDMH (mechanically-scribed core steel) $1.47 $2.75 

SA1 (amorphous) – finished core, volume production $1.80 $2.50 

Copper wire, formvar, round #10-20 $1.55 $2.25

* Five year average (2000 through 2004) for materials expressed in 2004$ per lb. Average compiled by Paul Goethe, 

Optimized Program Service, January 2005. 
12A-5

5.2.In the Department’s analysis, material costs are marked up to determine the manufacturer sales price. 

In light of the large increases of material costs, have you changed your material markup factors or 

practices? 

5.3.Are the materials necessary to build more energy efficient transformers readily available? 

5.4.Have your company’s procurement practices changed in response to recent commodity price volatility? 

5.5.Have recent material price changes affected your company’s business? 

6. SHIPMENT PROJECTIONS 

6.1 An efficiency standard can affect shipments by changing product attributes, marketing approaches, 

product availability, and price. For the ANOPR and NOPR, a small sensitivity of liquid-immersed 

shipments to price is modeled. Do you consider this to be appropriate? 

6.2 What is your company’s approximate market share in each of the liquid-immersed design lines? 

Within each design line, is your proportion of shipments at each kVA rating the same as the industry 

average? 

6.3 Would you expect your market share to change once standards become effective? Does your outlook 

change with higher efficiency levels?

7. CONVERSION COSTS 

An increase in efficiency standards may cause your company to incur one-time costs. We call these 

conversion costs because they are the costs of changing your business to comply with new efficiency 

standards. The GRIM considers three types of conversion costs: 

• Conversion Capital Expenditures—One-time investments in plant, property, and equipment (PPE) 

necessitated by an efficiency standard. These may be completely incremental to existing PPE or they 

could involve replacement of existing PPE. 

• Product Conversion Expenses—One-time expenses in research, product development, testing, and 

marketing necessitated by an appliance efficiency standard. 

• Annual Compliance Costs (not technically a conversion cost) – On-going expenses incurred to comply 

with efficiency standards, typically to meet testing requirements. 
12A-6

7.1 What level of conversion costs do you anticipate incurring under the different Trial Standard Levels? 

Refer to the tables below to provide your company’s estimates. Please provide additional qualitative 

information to help us understand the nature of your investments.

7.2 What portion of your conversion capital expenditures will go towards replacing existing assets that 

would become obsolete under an efficiency standard? Does your answer depend upon the TSL? 

7.3 What are the depreciation periods for the three types of capital expenditures (building, equipment, 

tooling)? 

7.4 What specific annual compliance costs (after the effective date) do you anticipate incurring to comply

with standards? Will they vary with standard level? Would they vary over time (e.g., increase with 

sales)? 
12A-7

8. PRODUCT MIX 

Current differences in product mix (distribution of product sales by efficiency level) among manufacturers 

can lead to different reactions to and impacts from new efficiency standards. The GRIM calculates 

financial results at each efficiency level to capture some of these effects. 

8.1 What is the typical efficiency of a non-evaluated transformer for each representative unit? 

8.2 What percentage of product in each design line is TP1-compliant (industry-wide)? Do significant 

fractions of product exceed TP1 efficiency levels (industry-wide)? Comment on any differences 

between the industry’s distribution of product efficiencies and your company’s. 

8.3 Do you expect the product efficiency mix to shift over time in the base case? Why or why not? 

8.4 For each design line and corresponding TSL, please comment on the potential for marketing premium 

products (i.e., those with efficiencies significantly above of the TSL). What might be the percentage

of premium efficiency products sold at each TSL? 

9. MARKUPS AND PROFITABILITY 

One of the primary objectives of the Manufacturer Impact Analysis is to assess the impact of Trial 

Standard Levels on industry and sub-group profitability. In this section, we would like your assistance 

understanding how the Trial Standard Levels would impact your company’s markups and profitability. 

9.1 The non-production cost markup is defined as the factor applied to the full production costs to arrive at 

the Manufacturer Selling Price. The Manufacturer Selling Price allows the company to recover all 

costs, both production and non-production, and to earn a profit. The Department used a nonproduction cost markup of 1.25 for SG&A, R&D, interest, and profit. This represents a 20% gross 

margin on sales price. 

9.1.1 How does the industry average of 1.25 compare with your non-production cost markup? 

9.1.2 Has the average mark-up changed as a result of higher material costs? 

9.1.3 Is the mark-up on a TP1 product different? 

9.2 What other factors might change the industry’s profitability? 

9.3 Has recent commodity price volatility affected the industry’s profitability? 

10. REFURBISHMENT 

10.1 How do you expect new standards to impact the size and profitability of the refurbished distribution 

transformer market? 
12A-8

11. CUMULATIVE REGULATORY BURDEN 

Cumulative regulatory burden refers to the burden that industry faces from overlapping effects of new or 

revised DOE standards and/or other regulatory actions affecting the same products or industry. 

11.1 Are there other recent or impending regulations that distribution transformers face (from DOE or

otherwise)? How might an energy efficiency standard impact the cumulative regulatory burden faced 

by your company? 

11.2 Are there any other DOE standards that would pose a significant impact on your company (any 

division) within three years of the proposed effective date for efficiency standards (2010)? 

11.3 Under what circumstances would you be able to coordinate any expenditures related to metrification, 

other regulations, and distribution transformer efficiency standards, thereby lessening the cumulative

burden? 

12. EXPORTS / FOREIGN COMPETITION / OUTSOURCING 

Disparity between domestic and foreign efficiency standards could impact exports or imports. Labor 

content and material changes - resulting from efficiency standards - may impact sourcing decisions. 

12.1 Does the bulk of your company’s transformer production occur domestically? Absent standards, are

production facilities being relocated to foreign countries? Would standards impact your domestic vs. 

foreign manufacturing decision? How? 

12.2 Could a new standard affect your export sales? What would the resulting impact be, if any, on your 

manufacturing operations and profitability? 

12.3 What percentage of the U.S. market has been captured by foreign competition? Would standards 

have an impact on foreign competition? How? 

13. DIRECT EMPLOYMENT IMPACT ASSESSMENT 

The impact of new energy efficiency standards on employment is an important consideration in the 

rulemaking process. This section of the interview guide seeks to explore current trends in transformer 

production employment and solicit manufacturer views on how domestic employment patterns might be 

affected by new energy efficiency standards. 

13.1 Would your domestic employment levels change under new energy efficiency standards? 

13.2 Would the workforce skills necessary under new energy efficiency standards require extensive 

retraining or replacement of employees? 

14. CONSOLIDATION 

New efficiency standards can alter the competitive dynamics of the market. This can include prompting

companies to enter or exit the market, or to merge. The DOE and the Justice Department are both 
12A-9

interested in any potential reduction in competition that would result from a new efficiency standard.

14.1 Please comment on industry consolidation and related trends over the last 5 years. 

14.2 In the absence of new standards, do you expect any industry consolidation? Please describe your

expectations. 

14.3 How would new standards affect your ability to compete? 

14.4 Could new standards disproportionately advance or harm the competitive positions of some firms 

(e.g., small businesses)? 

14.5 Could new standards result in disproportionate economic or performance penalties for particular 

consumer subgroups? 

14.6 Could new standards result in products that will be less desirable to consumers (not considering price 

effects)? Which attributes could be affected? 

15. NICHE PRODUCTS 

The definition of a distribution transformer excludes certain types of transformers from this rulemaking. 

For transformers that are covered, DOE is interested in whether new standard levels for some sub-groups 

of products might threaten their viability because of either technical or commercial considerations. 

15.1 Do you have any products whose viability could be threatened by a higher efficiency standard? If so, 

please identify the threatened products and the threshold Trial Standard Level that poses a threat. 

15.2 What would you have to do in order to ensure the viability of those products? 

15.3 For the purposes of the GRIM, DOE has separated the distribution transformer industry into three 

main groups – liquid-immersed, low voltage dry, and medium voltage dry. Are there other industry 

groupings that might be meaningful? 

16. EFFECTIVE DATE OF STANDARDS

The effective date for new standards after the regulation is promulgated is currently expected to be 2010 

(final rule to be published in 2007). 

16.1 Is this 3-year lead time for retooling, redesign, and compliance demonstration feasible/adequate? If 

the answer depends on the new standard level, please explain. 

16.2 If the effective date were postponed, would the burden of the standard on your company be reduced? 

 

17. MISCELLANEOUS 

17.1 Are there any federal tax credits or other incentive programs to encourage you to produce energy 

efficient transformers?

kVA single-phase efficiency standard will be based upon the 300 kVA three-phase standard). 

1.4 What are the key issues for your company regarding the distribution transformer energy conservation 

standard rulemaking? 

1.5 How significant are the above key issues at each Trial Standard Level? 

1.6 How can we most effectively incorporate these issues in the Manufacturer Impact Analysis?

2. COMPANY OVERVIEW AND ORGANIZATIONAL CHARACTERISTICS

The Department’s interest concerning manufacturer impact is focused at the plant or profit center level 

directly pertinent to transformer production. However, the context within which the plant operates and the 

details of plant production and costs are not readily available from the published literature, so the 

Department invites you to provide these details confidentially in your own words to the extent practical. 

The organizational setting around the transformer profit center is of interest to round out the Department’s 

understanding of the probable future of the transformer manufacturing activity with and without energy

efficiency standards. 

2.5 Do you have a parent company, and/or any subsidiaries relevant to the transformer industry?

4. MORE EFFICIENT DESIGNS 

The Department’s engineering analysis models improvements in efficiency by considering alternative 

combinations of design factors such as core steels, winding conductors, and joint configurations. The

Department would like to understand what changes may be necessary in your product designs for the 

production of higher efficiency medium-voltage dry-type distribution transformers. 

4.6 What are your current design features? For each design line, which materials are used to build your 

non-evaluated transformers? What joint types are used? 

4.7 Does your company build TP1-compliant transformers? How do these designs compare to your nonevaluated transformers? 

4.8 Does your company build transformers that significantly exceed TP1 efficiency levels? Which designs 

are used to exceed TP1? Which designs would you likely use to meet the various TSLs? 

4.9 Are there any other manufacturing issues that DOE should be aware of in terms of producing more 

energy efficient transformers at your facility? 

4.10 Do you currently fabricate your own cores and coils? Would the standard level change your

5.7.In the Department’s analysis, material costs are marked up to determine the manufacturer sales price. 

In light of the large increases of material costs, have you changed your material markup factors or 

practices? 

5.8.Are the materials necessary to build more energy efficient transformers readily available? 

5.9.Have your company’s procurement practices changed in response to recent commodity price volatility? 

5.10. Have recent material price changes affected your company’s business? 

6. SHIPMENT PROJECTIONS 

6.4 An efficiency standard can affect shipments by changing product attributes, marketing approaches, 

product availability, and price. In the ANOPR, the Department assumed that industry-wide dry-type 

shipments do not vary by standard level (i.e., there is no consumer sensitivity to price). For the 

NOPR, a small sensitivity of dry-type shipments to price may be introduced. Do you consider this to 

be appropriate? 

6.5 What is your company’s approximate market share in each of the medium-voltage design lines? 

Within each design line, is your proportion of shipments at each kVA rating the same as the industry 

average? 

6.6 Would you expect your market share to change once standards become effective? Does your outlook 

change with higher efficiency levels?
12A-15

7. CONVERSION COSTS 

An increase in efficiency standards may cause your company to incur one-time costs. We call these 

conversion costs because they are the costs of changing your business to comply with new efficiency 

standards. The GRIM considers three types of conversion costs: 

• Conversion Capital Expenditures—One-time investments in plant, property, and equipment (PPE) 

necessitated by an efficiency standard. These may be completely incremental to existing PPE or they 

could involve replacement of existing PPE. 

• Product Conversion Expenses—One-time expenses in research, product development, testing, and 

marketing necessitated by an appliance efficiency standard. 

• Annual Compliance Costs (not technically a conversion cost) – On-going expenses incurred to comply 

with efficiency standards, typically to meet testing requirements. 

7.5 What level of conversion costs do you anticipate incurring under the different Trial Standard Levels? 

Refer to the tables below to provide your company’s estimates. Please provide additional qualitative 

information to help us understand the nature of your investments.

tooling)? 

7.8 What specific annual compliance costs (after the effective date) do you anticipate incurring to comply

with standards? Will they vary with standard level? Would they vary over time (e.g., increase with 

sales)? 

8. PRODUCT MIX 

Current differences in product mix (distribution of product sales by efficiency level) among manufacturers 

can lead to different reactions to and impacts from new efficiency standards. The GRIM calculates 

financial results at each efficiency level to capture some of these effects. 

8.5 What is the typical efficiency of a non-evaluated transformer for each representative unit? 

8.6 What percentage of product in each design line is TP1-compliant (industry-wide)? Do significant 

fractions of product exceed TP1 efficiency levels (industry-wide)? Comment on any differences 

between the industry’s distribution of product efficiencies and your company’s. 

8.7 Do you expect the product efficiency mix to shift over time in the base case? Why or why not? 

8.8 For each design line and corresponding TSL, please comment on the potential for marketing premium 

products (i.e., those with efficiencies significantly above of the TSL). What might be the percentage

of premium efficiency products sold at each TSL? 

9. MARKUPS AND PROFITABILITY 

One of the primary objectives of the Manufacturer Impact Analysis is to assess the impact of Trial 

Standard Levels on industry and sub-group profitability. In this section, we would like your assistance 

understanding how the Trial Standard Levels would impact your company’s markups and profitability. 

9.4 The non-production cost markup is defined as the factor applied to the full production costs to arrive at 

the Manufacturer Selling Price. The Manufacturer Selling Price allows the company to recover all 

costs, both production and non-production, and to earn a profit. The Department used a nonproduction cost markup of 1.25 for SG&A, R&D, interest, and profit. This represents a 20% gross 

margin on sales price. 

9.4.1 How does the industry average of 1.25 compare with your non-production cost markup? 

9.4.2 Has the average mark-up changed as a result of higher material costs? 

9.4.3 Is the mark-up on a TP1 product different? 

9.5 What other factors might change the industry’s profitability? 

9.6 Has recent commodity price volatility affected the industry’s profitability?

10. REFURBISHMENT 

10.1 How do you expect new standards to impact the size and profitability of the refurbished distribution 

transformer market? 

11. CUMULATIVE REGULATORY BURDEN 

Cumulative regulatory burden refers to the burden that industry faces from overlapping effects of new or 

revised DOE standards and/or other regulatory actions affecting the same products or industry. 

11.1 Are there other recent or impending regulations that distribution transformers face (from DOE or

otherwise)? How might an energy efficiency standard impact the cumulative regulatory burden faced 

by your company? 

11.2 Are there any other DOE standards that would pose a significant impact on your company (any 

division) within three years of the proposed effective date for efficiency standards (2010)? 

11.3 Under what circumstances would you be able to coordinate any expenditures related to metrification, 

other regulations, and distribution transformer efficiency standards, thereby lessening the cumulative

burden? 

12. EXPORTS / FOREIGN COMPETITION / OUTSOURCING 

Disparity between domestic and foreign efficiency standards could impact exports or imports. Labor 

content and material changes - resulting from efficiency standards - may impact sourcing decisions. 

12.1 Does the bulk of your company’s transformer production occur domestically? Absent standards, are

production facilities being relocated to foreign countries? Would standards impact your domestic vs. 

foreign manufacturing decision? How? 

12.2 Could a new standard affect your export sales? What would the resulting impact be, if any, on your 

manufacturing operations and profitability? 

12.3 What percentage of the U.S. market has been captured by foreign competition? Would standards 

have an impact on foreign competition? How? 

13. DIRECT EMPLOYMENT IMPACT ASSESSMENT 

The impact of new energy efficiency standards on employment is an important consideration in the 

rulemaking process. This section of the interview guide seeks to explore current trends in transformer 

production employment and solicit manufacturer views on how domestic employment patterns might be 

affected by new energy efficiency standards. 

13.3 Would your domestic employment levels change under new energy efficiency standards? 

13.4 Would the workforce skills necessary under new energy efficiency standards require extensive 

retraining or replacement of employees? 
12A-18

14. CONSOLIDATION 

New efficiency standards can alter the competitive dynamics of the market. This can include prompting

companies to enter or exit the market, or to merge. The DOE and the Justice Department are both 

interested in any potential reduction in competition that would result from a new efficiency standard.

14.1 Please comment on industry consolidation and related trends over the last 5 years. 

14.2 In the absence of new standards, do you expect any industry consolidation? Please describe your

expectations. 

14.3 How would new standards affect your ability to compete? 

14.4 Could new standards disproportionately advance or harm the competitive positions of some firms 

(e.g., small businesses)? 

14.5 Could new standards result in disproportionate economic or performance penalties for particular 

consumer subgroups? 

14.6 Could new standards result in products that will be less desirable to consumers (not considering price 

effects)? Which attributes could be affected? 

15. NICHE PRODUCTS 

The definition of a distribution transformer excludes certain types of transformers from this rulemaking. 

For transformers that are covered, DOE is interested in whether new standard levels for some sub-groups 

of products might threaten their viability because of either technical or commercial considerations. 

15.1 Do you have any products whose viability could be threatened by a higher efficiency standard? If so, 

please identify the threatened products and the threshold Trial Standard Level that poses a threat. 

15.2 What would you have to do in order to ensure the viability of those products? 

15.3 For the purposes of the GRIM, DOE has separated the distribution transformer industry into three 

main groups – liquid-immersed, low voltage dry, and medium voltage dry. Are there other industry 

groupings that might be meaningful? 

16. EFFECTIVE DATE OF STANDARDS

The effective date for new standards after the regulation is promulgated is currently expected to be 2010 

(final rule to be published in 2007). 

16.1 Is this 3-year lead time for retooling, redesign, and compliance demonstration feasible/adequate? If 

the answer depends on the new standard level, please explain. 

16.2 If the effective date were postponed, would the burden of the standard on your company be reduced? 

 
12A-19

17. MISCELLANEOUS 

17.1 Are there any federal tax credits or other incentive programs to encourage you to produce energy 

efficient transformers?
