One further question for PSE to respond to at their October 5, IRP Advisory Group
meeting, i.e. Why has PSE chosen not to re-run their flawed EE load flow studies
to fix the flaws?
Michele-
In your recent email sending out the Draft 2017 PSE IRP you state: "After reviewing the
material, if you have concerns or questions, please let me know, and we will include them at the
October 5 IRPAG meeting."
On Tuesday September 12, 2017 I sent to you a series of comments and questions on PSE's
Draft IRP that I asked that be responded to at the October 5, IRPAG meeting.
By this email I am asking another question that I ask be responded to at the October 5, IRPAG
meeting. This question is teed up by the document included in the records for UE-160918 titled
"160918 Fatal Flaws in the PSE justification of the need for Energize Eastside.pdf" posted on the
WUTC web site on August 21,2017.
The question is:
PSE has been aware for some time that it should not have required the flows to and from
Canada in their load flow studies. Further, PSE is fully aware that they cannot meet their
winter peak loads with their west of Cascades generation fully off. That being the case, why
has PSE not rerun the load flow studies to correct these flaws in the studies they ran to
attempt to show the need for Energize Eastside?
****************
I look forward to getting a response to this question (and the other questions, challenges and
concerns I provided in my September 12,2017 email) at the October 5, IRPAG meeting.
