AEP Southwestern Electric Power Co. is seeking a 15% hike that would take effect in January 2022. SWEPCO said that the company submitted a request to the Public Utility Commission of Texas for a net annual increase of $90.2 million in its non-fuel base rates. For a Texas residential customer using 1,000 kilowatt-hours per month, the change would result in an overall bill increase of almost $16 per month.
