1.0 Proposed Commencement and Completion Dates

The preliminary development schedule for the Seminoe Pumped Storage Project (Project) is presented in Appendix A to this Exhibit C. The key dates which have been established or forecast are as follows:

Table 1.0-1. Proposed Commencement and Completion Dates Description Key Date

Granting of License by Federal Energy Regulatory Commission (FERC) March 2025 Completion of Land Lease/Purchase Arrangements November 2025 Start of Construction October 2026 Commercial Operation of First Unit June 2031 Commercial Operation of Whole Project September 2031

The construction schedule presented herein estimates 5 years for construction of the main Project facilities, after a year of design by an Engineer Procure Construct (EPC) contractor.

2.0 Operation Dates

Unit 1 is scheduled for start of commercial operation in June 2031. Subsequent units are scheduled with an interval of two months: Unit 2 at the end of July 2031, and Unit 3 at the end of September 2031.

The initial operation of the first pump-turbine will be in pumping mode and water must be available to provide head against which the pump will start. Therefore, the construction sequence of the upper reservoir dam will be organized so that the structure placement on the east side—up to a level of approximately elevation 7,305 feet—will be completed first, together with the reservoir lining. In this way, snow melt and rain can be impounded and collected during construction. As a result, up 96 acre-feet will be available to be pumped into the vertical pressure shaft thus, lowering the amount of water needing to be pumped into the upper reservoir for the initial fill.

Starting up the first unit must commence in pumping mode (i.e., pumping water from the Seminoe Reservoir to the upper reservoir); therefore, the upper reservoir will not be filled prior to the commissioning of the units. Subsequent units may be started in generating mode as the upper reservoir can be filled by the first unit. Commerical operation can commence after the first unit it commissioned.
