Disaggregation of Operating Revenues |
Operating revenues disaggregated by revenue source | 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.

Revenues from contracts with customers | Other non-utility revenues |
Disaggregation of Operating Revenues |
Operating revenues disaggregated by revenue source | Other non-utility operating revenues consist primarily of the following:
|  | Three Months Ended March 31
(in millions) |  | 2020 |  | 2019
Wind generation revenues |  | $ | 9.3 |  |  | $ | 6.2 |
We Power revenues * |  | 5.5 |  |  | 6.4 |
Appliance service revenues |  | 4.4 |  |  | 4.1 |

Other |  | — |  |  | 0.1 |
Total other non-utility operating revenues |  | $ | 19.6 |  |  | $ | 18.3 |
* | As part of the construction of the We Power electric generating units, 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 deferred revenue, and we continually amortize the deferred carrying costs to revenues over the life of the related lease term that We Power has with WE. During the three months ended March 31, 2020 and 2019, we recorded $5.5 million and $6.4 million, respectively, of revenues related to these deferred carrying costs, which were included in the contract liability balance at the beginning of the period. This contract liability is presented as deferred revenue, net on our balance sheets.
Other operating revenues |
Disaggregation of Operating Revenues |
Operating revenues disaggregated by revenue source | Other operating revenues consist primarily of the following:
|  | Three Months Ended March 31
(in millions) |  | 2020 |  | 2019
Late payment charges |  | $ | 12.1 |  |  | $ | 13.2 |
Alternative revenues * |  | 8.5 |  |  | (19.7 | )
Other |  | 1.1 |  |  | 7.4 |
Total other operating revenues |  | $ | 21.7 |  |  | $ | 0.9 |
* 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, and conservation improvement rider true-ups, as discussed in Note 1(d), Operating Revenues, in our 2019 Annual Report on Form 10-K.
