Subject: Re: MV LCC and PBP Sensitivity Results: Materials Exclusion, ZDMH, H0, and SA1

Per my earlier email (and Wes's response): These runs simply show that M3 is priced at an EL0 efficiency

and has to be repriced to show better LCCs an be competitive at higher efficiencies. At some point M3

hits an asymptote where it becomes an actually efficiency issue; but that's probably closer to EL5+

rather than EL0.1. The cost/efficiency curves for ZDMH, HO and SA1 are simply flatter. Our objective is

to locate the technical asymptote for M3, where it can compete but at a lower price consistent with its

performance properties relative to other materials, not to set a standard that acts as a price support for

M3.

Good afternoon Chris and all:

I commend your work to run these design lines excluding ZDMH and HO and SA1 to test the sensitivity.

Under this scenario you are coming much closer to the relationships that I found for the manufacturers

that I had run designs using M3.  There is not much room for higher efficiencies on an M3 base which

just speaks to the thorough job that the DOE did in the last rule making.  If you have not already done

so, I would recommend that you explore options between the current mandatory standard and EL1,

perhaps in 1/10th steps from EL0, EL0.1, EL 0.2, etc...to EL1.0.

It is not clear to me whether there will be future DOE revisits to explore Distribution Transformer Energy

Efficiency but as higher performing core materials become more widely available then there may be

better opportunities for efficiency increases than is now apparent with an M3 base.

Best regards,

Phil

Subject: MV LCC and PBP Sensitivity Results: Materials Exclusion, ZDMH, H0, and SA1

Dear Committee Members,

Please find draft LCC and PBP sensitivity results for both liquid‐immersed and dry‐type medium voltage

transformers (design lines 1‐5, 9 ‐13B) attached. The sensitivity excludes ZDMH, H0 and SA1 as core

materials from sample of designs options.

Thank you,

‐ Chris
