(1) Our exposure to credit losses for certain regulated utility customers is mitigated by regulatory mechanisms we have in place. Specifically, rates related to all of the customers in our Illinois segment, as well as the residential rates of WE, WPS, and WG in our Wisconsin segment, include riders or other mechanisms for cost recovery or refund of uncollectible expense based on the difference between the actual provision for credit losses and the amounts recovered in rates. As a result, at December 31, 2024, $1,029.0 million, or 61.6%, of our net accounts receivable and unbilled revenues balance had regulatory protections in place to mitigate the exposure to credit losses. See Note 26, Regulatory Environment, for more information on PGL and NSG's UEA rider for cost recovery or refund of uncollectible expense based on the difference between actual uncollectible write-offs and amounts recovered in rates.

Rollforward of the allowances for credit losses by reportable segment

A rollforward of the allowance for credit losses by reportable segment for the years ended December 31, 2024, 2023, and 2022, is included below:


(in millions)	Wisconsin		Illinois		Other States		WEC Energy Group Consolidated
Balance at January 1, 2024	$	77.4	$	109.7	$	6.4	$	193.5
Provision for credit losses	52.1		52.3		0.5		104.9
Provision for credit losses deferred for future recovery or refund	43.8		(8.0)		—		35.8
Write-offs charged against the allowance	(141.8)		(95.0)		(6.6)		(243.4)
Recoveries of amounts previously written off	42.1		24.9		5.0		72.0
Balance at December 31, 2024	$	73.6	$	83.9	$	5.3	$	162.8

On a consolidated basis, there was a $30.7 million decrease in the allowance for credit losses during the year ended December 31, 2024, largely driven by customer write-offs. We also believe that the lower energy costs that customers were seeing, which were driven by warmer than normal weather conditions during most of 2024 and low average natural gas prices, contributed to a reduction in past due accounts receivable balances and a related decrease in the allowance for credit losses.


(in millions)	Wisconsin		Illinois		Other States		WEC Energy Group Consolidated
Balance at January 1, 2023	$	82.0	$	111.0	$	6.3	$	199.3
Provision for credit losses	40.9		26.3		4.8		72.0
Provision for credit losses deferred for future recovery or refund	52.5		35.8		—		88.3
Write-offs charged against the allowance	(131.6)		(85.4)		(6.6)		(223.6)
Recoveries of amounts previously written off	33.6		22.0		1.9		57.5
Balance at December 31, 2023	$	77.4	$	109.7	$	6.4	$	193.5

On a consolidated basis, there was a $5.8 million decrease in the allowance for credit losses during the year ended December 31, 2023, primarily related to lower customer energy costs (driven by the warmer weather during the fourth quarter of 2023 when compared to the same quarter in 2022 and lower natural gas prices), which contributed to a reduction in past due accounts receivable balances and a related decrease in the allowance for credit losses. Customer write-offs also contributed to the decrease in the allowance for credit losses.


(in millions)	Wisconsin		Illinois		Other States		WEC Energy Group Consolidated
Balance at January 1, 2022	$	84.0	$	105.5	$	8.8	$	198.3
Provision for credit losses	50.5		33.0		2.6		86.1
Provision for credit losses deferred for future recovery or refund	29.7		33.2		—		62.9
Write-offs charged against the allowance	(117.0)		(82.6)		(6.4)		(206.0)
Recoveries of amounts previously written off	34.8		21.9		1.3		58.0
Balance at December 31, 2022	$	82.0	$	111.0	$	6.3	$	199.3

On a consolidated basis, there was a $1.0 million increase in the allowance for credit losses during the year ended December 31, 2022. We believe that the high energy costs that customers were seeing, which were driven by high natural gas prices, contributed to higher past due accounts receivable balances and a related increase in the allowance for credit losses. The increase was substantially offset by customer write-offs related to collection practices returning to pre-pandemic levels, including the restoration of our ability to disconnect customers.
