Revenue from Contract with Customer [Abstract] |
OPERATING REVENUES | OPERATING REVENUES For more information about our significant accounting policies related to operating revenues, see Note 1(d), Operating Revenues. 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 has 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. (2) During 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 customers, they are reflected in retail revenues with an offsetting decrease in other utility revenues. (3) During 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. See Note 26, Regulatory Environment, for more information. Other Natural Gas Operating Revenues We have other natural gas operating revenues from Bluewater, which is in our non-utility energy infrastructure segment. Bluewater has entered into long-term service agreements for natural gas storage services with WE, WPS, and WG, and also provides limited service to unaffiliated customers. All amounts associated with the service agreements with WE, WPS, and WG have been eliminated at the consolidated level. Other Non-Utility Operating Revenues Other non-utility operating revenues consist primarily of the following:

Wind generation revenues |  | $ | 101.0 |  |  | $ | 60.3 |  |  | $ | 34.6 |
We Power revenues |  | 23.4 |  |  | 23.3 |  |  | 22.9 |
Appliance service revenues |  | 18.7 |  |  | 17.8 |  |  | 17.1 |
Other |  | 0.1 |  |  | 0.1 |  |  | 1.7 |
Total other non-utility operating revenues |  | $ | 143.2 |  |  | $ | 101.5 |  |  | $ | 76.3 |
Other Operating Revenues Other operating revenues consist primarily of the following:
|  | Year Ended December 31
(in millions) |  | 2022 |  | 2021 |  | 2020
Late payment charges (1) |  | $ | 55.6 |  |  | $ | 54.9 |  |  | $ | 29.4 |
Alternative revenues (2) |  | (30.3) |  |  | 21.2 |  |  | 38.8 |
Other |  | 4.0 |  |  | 4.2 |  |  | 4.2 |
Total other operating revenues |  | $ | 29.3 |  |  | $ | 80.3 |  |  | $ | 72.4 |
(1) The increase in late payment charges during 2021, compared with 2020, was a result of the expiration of various regulatory orders from our utility commissions in response to the COVID-19 pandemic, which included the suspension of late payment charges during a designated time period. See Note 26, Regulatory Environment, for more information. (2) 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.
