Generation at the system level is apportioned to Washington and Idaho jurisdictions by the P/T ratio (34.76% in 2015 and 35.29% in 2016 for Idaho). All Palouse RECs have been sold or are in inventory.

Staff_PR_074C Confidential Attachment A is a worksheet showing Palouse Wind REC sales for the period 2012 to date. REC revenue is apportioned to each state based on the P/T ratio.
