Q. What are the main factors driving the revenue 5
change requested in this case? 6
A. The increase in this year’s PCA is driven by 7
an increase in both the forecast component and the 8
Balancing Adjustment. The increase in this year’s forecast 9
component is attributed primarily to higher forecast market 10
energy and natural gas prices, combined with a limited coal 11
supply. 12
As can be seen on Table 1, the Balancing Adjustment 13
accounts for over 75 percent of the overall PCA revenue 14
change, indicating that last year’s actual power costs were 15
greater than forecast. Similar to the forecast component, 16
the increase in the Balancing Adjustment is largely 17
attributed to high natural gas and market energy prices 18
during the 2022-2023 PCA Year, combined with a limited coal 19
