REQUEST:
Please explain the 21% increase in the 349,554 MWh of forecasted Pro Forma Palouse Wind to actual 288,227 MWh of 2014 generation illustrated in the 2015 Idaho PCA. See Case No. AVE-E-15-07, Exhibit 1 to Ehrbar Direct Testimony at 2.
RESPONSE:
The 2015 Idaho PCA period was July 2014 through June 2015. Generation for that period was 288,227 MWh. Generation during calendar year 2014 was 335,291 MWh. Since there is not yet five years of actual generation data, the pro forma uses the expected generation at Palouse provided by the plant owner based on their meteorological data. Once there is five years of actual generation, a five-year average of generation will be used in future pro formas.
