order approving a waiver of solicitation requirements, proposed by Commission Staff("Staff') in
Case No. GNR-E-25-01,in connection with the Company's power purchase agreement concerning
the Natrium Reactor Plant, Kemmerer Power Station Unit 1 ("KU1").
We now issue this Order providing Notice of Application and Notice of Modified
Procedure, establishing deadlines for the submission of written comments.

sodium-cooled nuclear steam electric generating plant coupled with a molten salt integrated energy
storage system."Id.
YOU ARE FURTHER NOTIFIED that the Company states that due to the time-sensitive
nature of the KU1 project, it is seeking a waiver from the Request for Proposal ("RFP") process
proposed by Staff in Case No. GNR-E-25-01.1 Id. The Company states that under Staffs
proposals, prior to the acquisition of an electrical resource of 100 megawatts or greater for a

solicit resources by issuing an RFP.Id. at 4.

NOTICE OF APPLICATION
NOTICE OF MODIFIED PROCEDURE
ORDER NO. 36907 1

YOU ARE FURTHER NOTIFIED that according to the Company, under Staffs
proposals, the Commission would grant waivers to the RFP process upon the utility's showing of
a unique economic opportunity that justifies bypassing the usual solicitation requirements. Id.
YOU ARE FURTHER NOTIFIED that the Company characterizes its power purchase
agreement ("PPA") related to KUI as a unique economic opportunity due to: (1) the significant
advancements in nuclear technology embodied in KUI, which allow for uncommon energy
dispatchability and operational flexibility; (2) comprehensive risk management and safety
provisions included in the PPA, including significant protections for unknown performance risks
associated with KUI and the federal safety oversight inherent in a nuclear project; and (3)
cognizable long-term benefits, such as operational knowledge that the Company can deploy in
future opportunities. Id. at 4-7.
YOU ARE FURTHER NOTIFIED that the Company represents that forgoing the RFP
process for the PPA is in the public interest and necessary for several reasons that are unique to
the KUI project. Id. at 7. Specifically, the Company states that federal funding requirements, the
unique commercial opportunity, the geographic and infrastructure limitations connected to the
Company's use of Naughton, and a lack of viable alternatives with the same benefits make the
PPA a time-sensitive opportunity and obviate the need for an RFP process. Id. at 7-9.
YOU ARE FURTHER NOTIFIED that the Company states that the KU1 project has been
included in its three most recent Integrated Resource Plans as part of the least-cost, least-risk
portfolio of resource options.Id. at 9.
