in turquoise in this scenario), the CNPPID total diversion must be chosen and entered manually. <br />? Column 13: The EA diversion at the CNPPID diversion dam is equal to the minimum of the EA flow <br />available at the confluence (col 10) and the canal capacity of 2,250 cfs. Computationally, this moves as <br />much EA flow available mto the CNPPID canal as possible before addrtional non-EA water is added. For <br />days of intentional EA bypass (shown in turquoise in this scenario), the amount of EA diverted at the <br />CNPPID diversion must be chosen and entered manually, and should be less than the amount of EA <br />available shown in column 10. <br />Column 14: The total flow passing the CNPPID diversion dam is the total flow at the confluence (co19) <br />minus the CNPPID total diversion (col 12). In the worksheet, EA flow and non-EA flow passing the <br />CNPPID canal is not further identified separately in the Platte River, and the total flow passing the <br />diversion may be comprised solely of either, or both, categories. <br />Column 15: The "intentional EA bypass" is computed as follows: If the CNPPID total diversion (col 12) <br />is less than the canal capacity (2,250 cfs), then the intentional EA bypass is the smaller of: a) the flow that <br />could have been diverted (2,250 minus the CNPPID total diversion in col 12), or b) the total flow passing <br />the CNPPID diversion (col 14). Because of the check for available CNPPID canal space, this column does <br />not necessarilv represent the actual EA water passing the CNPPID diversion dam, but only the flow <br />passing the diversion which CNPPID could have diverted and is to be compensated for. As mentioned <br />previously, any EA water passing the CNPPID diversion is not separately identified downstream of the <br />diversion, but is included in the total flow passing the CNPPID diversion (col 14) if bypassed. <br />The estimated lost generation due to the intentional EA bypass is shown at the bottom of column 15. The <br />? NMWh/ac-ft factors for the Jeffrey, Johnson 1, and Johnson 2 powerplants are from Exhibit A of the EA <br />Bypass Agreement. The worksheet currently does not provide the ability to return EA water out of the <br />Jeffrey Return back to the Platte River. This ability would lower Bypass costs somewhat, and requires <br />adjustments in the worksheet to reflect that volume of waters' subsequent translation and timing at <br />Overton. <br />JOHNSON LAKE - HYDROCYCLING OPERATIONS <br />For purposes of illustrating EA reregulation in combination with hydrocycling operations, the Johnson <br />Reservoir inflow, reregulation, and J-2 outflow is segregated in the worksheet into "hydrocycling <br />operations" (columns 16-20) and "EA operations" (columns 21-25). These are then combined into the <br />total J-2 outflow shown in column 26. <br />Column 16: The total inflow at Johnson Reservoir is the total CNPPID diversion, lagged 2-days, <br />multiplied by a conveyance factor for that reach which is specified in cell B41 (currently, 0.75). The first <br />two days in the example are set to the same inflow as starting on day 3(because there are no previous two <br />days to compute on). <br />Column 17: The inflow available far hydrocycling by CNPPID is the total Johnson Lake inflow (col 16) <br />minus the EA inflow into Johnson Lake (col 21). (The EA inflow, also described later, is the EA diverted <br />at CNPPID, lagged 2 days, with the same conveyance factor in cell B41 applied.) <br />Column 18: Column 18 represents the volume of water that is re-regulated in Johnson Lake for a <br />• subsequent hydrocycle release.
