Subject: Re: MVLF and LV Groups 

Given that the presentation suggested load factors on the LV dry-type transformers in the 12 - 

16% range (with many even in the 6-7% range) due to fire codes, we should be looking at the 

lower end for those units. For MVLF, we might want to drop to 25% or 30% to address the 

market that many rural coops face.

I would like to see these calculations be done at both the 50% average load and at 35% average load to

Subject: RE: MVLF and LV Groups

 

Dear Robert:

You are correct that there is a definite KW‐HR savings that can be quantified in dollars, when higher

efficiency equipment is bought.   

When considering an investment,  for which an expected $ savings will occur,  most privately held

commercial and industrial companies feel they must obtain  a payback within  3‐5 years.  Should we not

see this financial attribute, the payback period,  be calculated with each of the design alternatives

referenced to the CSL‐0 designs, particularly in the non‐utility markets served by the LV and MV dry‐type

manufacturers?    The payback calculation is very simple:  You just divide your (incremental delivered 

transformer cost) by (the annual KW-HR savings). No present worth, LCC, discount rates or Crystal

Balls are needed.

Thanks,  

Bob Smith, PE

Subject: MVLF and LV Groups

 

I'd like to reconsider my response to John Cymbalsky, at the end of the LV meeting, regarding 

showing the cost per kWh saved (based on the incremental delivered transformer cost and the 

incremental energy savings, compared to dEL0). I believe John is correct and the cost per kWh 

SHOULD be shown for each dEL/TSL/CSL for the life of the transformer. This is simply the 

ratio of the 30 year stream of annual kWh savings (discounted at 3% and 7%) to the incremental 

delivered transformer cost. Showing this in all groups will provide a common comparison for all 

transformers as well as the a common reference for other energy savings programs in DOE's 

portfolios as well as the efficiency portfolios of the other participants. 

 

I, of course, remain supportive of Tom Panzer's recommendation for a TSL basis, also discussed 

at that meeting.

Robert A. Berman, Principal
