were to file "their first capacity deficiency cases after the Commission has acknowledged
their IRP reports." Avista filed its 2020 Electric IRP with the Commission on February 28,
2020. On October 15,2020, the Commission issued Order No. 34814 acknowledging the
2020IRP.

V. CAPACITY DEFICIENTY PERIOD
Avista's 2020 IRP identifies the first load deficit in January 2026. The deficit is a
direct result of the expected economic loss of Colstrip Units 3 and 4 no longer serving
Avista's customers system-wide at the end of 2025. \\e loss is compounded with the
expiration of the Lancaster PPA in October 2026. Figures I and 2 show the net peak
position for both the winter and summer peak hour positions from Figures 7-1 and 7-2 on
page 7-4 of the 2020 IRP respectively. Figure 3 shows Avista's annual average energy
load and resources balance as identified in Figure 7.3 of the 2020 IP.P on page 7-5.
