Natural Gas Expenses and Purchases of Electricity to be Recovered from Customers

For the time period of February 9, 2021, to February 20, 2021, SWEPCo’s natural gas expenses and purchases of electricity still to be recovered from customers are shown in the table below:

	December 31,				Approved	Approved
Jurisdiction	2024		2023		Recovery Period	Carrying Charge
	(in millions)
Arkansas	$	37.2	$	54.2	6 years	(a)
Louisiana	70.6		97.2		(b)	(b)
Texas	72.7		101.9		5 years	1.65%
Total	$	180.5	$	253.3

(a)SWEPCo is permitted to record carrying costs on the unrecovered balance of fuel costs at a weighted-cost of capital approved by the APSC. In August 2024, the APSC issued an order that found SWEPCo had prudently incurred these costs.

(b)In March 2021, the LPSC approved a special order granting a temporary modification to the FAC and shortly after SWEPCo began recovery of its Louisiana jurisdictional share of these fuel costs based on a five-year recovery period inclusive of an interim carrying charge equal to the prime rate. The special order states the fuel and purchased power costs incurred will be subject to a future LPSC audit.
