(a)Excludes KWHs generated from test period energy at Plant Vogtle Units 3 and 4 prior to each unit's respective in-service date. The related fuel costs were charged to CWIP in accordance with FERC guidance.

Also contributing to the decrease was a $55 million credit to nuclear fuel expense at Georgia Power resulting from litigation related to nuclear fuel disposal costs. See Note 3 to the financial statements under "Nuclear Fuel Disposal Costs" for additional information.
