as shown in the table above , net revenue for entergy wholesale commodities decreased by approximately $ 73 million in 2017 primarily due to the absence of net revenue from the fitzpatrick plant after it was sold to exelon in march 2017 and lower volume in the entergy wholesale commodities nuclear fleet resulting from more outage days in 2017 as compared to 2016 .
the decrease was partially offset by an increase resulting from the reimbursement agreement with exelon pursuant to which exelon reimbursed entergy for specified out-of-pocket costs associated with preparing for the refueling and operation of fitzpatrick that otherwise would have been avoided had entergy shut down fitzpatrick in january 2017 and a decrease in nuclear fuel expenses primarily related to the impairments of the indian point 2 , indian point 3 , and palisades plants and related assets .
revenues received from exelon in 2017 under the reimbursement agreement are offset by other operation and maintenance expenses and taxes other than income taxes and had no effect on net income .
