2014 Transmission costs were implemented February 1, 2014. The “Regional Transmission Service” (RTS) line captures the transmission costs from ITC Midwest and other transmission providers and breaks them out from the rest of a customer’s bill.
Regional Transmission Service Q&A
What is Regional Transmission Service?
Transmission is the high-voltage lines that carry power long distances between power plants and the neighborhood substations that serve our customers. The RTS line item reflects only the actual cost of this service.
What is the impact to my bill?
The average electric bill is made up of several parts. One of which is the cost for transmission service, labeled Regional Transmission Service (RTS). Because RTS only makes up only one part of your total bill, the overall impact on bills is much smaller, and will vary depending on customer class.
Here is the percentage increase for the RTS for each customer class for 2014:
|Customer Class||RTS Rate Unit||RTS Rate 2013||RTS Factor 2014||% Change||RTS Component of Overall Bill*||Overall Estimated Bill Impact|
|Large General Service||$/kW||6.68||7.26||9%||23%||2%|
*Percentage of total transmission to total annual bill.
How often will the rates for the transmission costs change?
Costs for transmission service are subject to the authority of the Federal Energy Regulatory Commission. Alliant Energy adjusts its charges annually to reflect any changes which have occurred for these transmission costs. The charge is per unit of energy you use, so the actual cost adjusts annually based on your usage and any change in the charge.
Why have transmission costs been increasing?
Transmission costs are increasing for all utilities. There are a significant number of transmission lines being built or upgraded. Such investments are needed to increase the ability to provide reliable power, integrate renewable resources and reduce costs to transmit power across the region, update an aging system, and in response to evolving regulation on planning, cost allocation, and environmental compliance.
