Disaggregation of Operating Revenues

Operating revenues disaggregated by revenue source

Disaggregation of Operating Revenues

The following tables present our operating revenues disaggregated by revenue source. We do not have any revenues associated with our electric transmission segment, which includes investments accounted for using the equity method. We disaggregate revenues into categories that depict how the nature, amount, timing, and uncertainty of revenues and cash flows are affected by economic factors. For our segments, revenues are further disaggregated by electric and natural gas operations and then by customer class. Each customer class within our electric and natural gas operations have different expectations of service, energy and demand requirements, and can be impacted differently by regulatory activities within their jurisdictions.

(1)Amounts eliminated represent lease revenues related to certain plants that We Power leases to WE to supply electricity to its customers. Lease payments are billed from We Power to WE and then recovered in WE's rates as authorized by the PSCW and the FERC. WE operates the plants and is authorized by the PSCW and Wisconsin state law to fully recover prudently incurred operating and maintenance costs in electric rates.

(1)Includes the revenues subject to the purchased gas recovery mechanisms of our utilities. For the three months ended September 30, 2022 and 2021, we continued to incur higher natural gas costs at all of our utility segments. The negative amount in Illinois reflects the timing of the billing of these high natural gas costs to its customers. As these amounts are billed to its customers, they are reflected in retail revenues with an offsetting decrease in other utility revenues.

(2)Includes the revenues subject to the purchased gas recovery mechanisms of our utilities. During the nine months ended September 30, 2022, we continued to recover natural gas costs we under-collected from our customers in 2021 related to the extreme weather experienced in February 2021, as well as higher natural gas costs incurred at the majority of our segments during 2022. As these amounts are billed to our customers, they are reflected in retail revenues with an offsetting decrease in other utility revenues.

(3)Includes the revenues subject to the purchased gas recovery mechanisms of our utilities. For the nine months ended September 30, 2021, in addition to costs related to the extreme weather event experienced in February 2021, we incurred higher natural gas costs as a result of an increase in the price of natural gas.

Disaggregation of Operating Revenues

Operating revenues disaggregated by revenue source

Other non-utility operating revenues consist primarily of the following:

	Three Months Ended September 30				Nine Months Ended September 30
(in millions)	2022		2021		2022		2021
Wind generation revenues	$	20.0	$	12.2	$	77.5	$	42.5
We Power revenues (1)	5.8		5.9		17.5		17.5
Appliance service revenues	4.8		4.3		13.9		13.4
Total other non-utility operating revenues	$	30.6	$	22.4	$	108.9	$	73.4

(1)As part of the construction of the We Power EGUs, we capitalized interest during construction, which is included in property, plant, and equipment. As allowed by the PSCW, we collected these carrying costs from WE's utility customers during construction. The equity portion of these carrying costs was recorded as a contract liability, which is presented as deferred revenue, net on our balance sheets. We continually amortize the deferred carrying costs to revenues over the related lease term that We Power has with WE.

Other operating revenues

Disaggregation of Operating Revenues

Operating revenues disaggregated by revenue source

Other operating revenues consist primarily of the following:

	Three Months Ended September 30				Nine Months Ended September 30
(in millions)	2022		2021		2022		2021
Late payment charges	$	13.6	$	11.9	$	43.5	$	44.2
Alternative revenues (1)	(2.4)		0.9		(19.7)		10.0
Other	0.7		0.7		3.3		3.6
Total other operating revenues	$	11.9	$	13.5	$	27.1	$	57.8

(1)Negative amounts can result from alternative revenues being reversed to revenues from contracts with customers as the customer is billed for these alternative revenues. Negative amounts can also result from revenues to be refunded to customers subject to decoupling mechanisms, wholesale true-ups, conservation improvement rider true-ups, and certain late payment charges.
