Dear Records -
Please file this email and is attachment as comments under PSE IRP Docket No. UE-160918.
1 have previously filed the Lauckhart-Schiffman load flow study that demonstrates there is no
need for Energize Eastside.
A. The best alternative for PSE to solve any possible future reliability problem on the east side
is for PSE to run all of its Puget Sound Area generation. ESE didconsider his alternati
ve
in thcir astside
B. The next best alternative for PSE to solve any possible future reliability problem on the
east side is for PSE to implement enhanced DSM programs including the possible installation
of battery banks on the east side. These programs have been discussed in the Energize
Eastside EIS. These programs have the added benefit of helping PSE meets its Total System
Peak deficiency. ESE did not =sjder thcs-e alternatives in their EaltLd-e-Needs Assessmert.
C. If any work on the transmission grid is needed to provide reliable service to the greater
Bellevue area, then a clear alternative that should be studied is looping the Seattle City Light
lire through Lakeside substation. PSE has rejected this alternative because they claim SCL will
not allow them to do that. But PSE never made a formal request to have SCL loop their line
through Lakeside. If PSE would make that formal request, SCL is required under FERC Order
890 to respond in accordance with the FERC ProForma Open Access Transmission Tariff
(OATT). See Attachment to this email. Only when PSE gets that response can they determine
if the SCL line option is the best alternative for providing reliable service to the east side. PSE
did oot properlonsider this alternative in their-Eastside Needs A ess ent.
D. Further, PSE should look at the alternative of building a 230/115 KV transformer at Lake
Tradition. The plan to install a new 230/115 KV transformer at Lake Tradition has been on
Puget's list for several years. PSE did not consider this alterna ive in their Eastside Needs
E. There is another alternative to Energize Eastside that many utilities are using today. They
are building small peaker plants in the vicinity of power constrained areas. This is a
particularly good option if the constraint wouid be expected to come in to play only very rarely
as is the case in the greater Bellevue area. That constraint only comes in to play when the
temperature reaches 23 degrees or below during peak load hours and when at the same time
two major 230/115 KV transformers on the east side fail. The small pecker plant is low cost
and takes little space and likely could be located at the Lakeside substation. It would almost
never run and if needed would run for only a short period of time. This alternative has the
added benefit helping PSE meets its Total System Peak deficiency. PSE did nQ1 ED-asider this
n their Lastside Needs Assessment.
