Regional transmission service refund
Alliant Energy’s Iowa utility does not own the transmission system in Iowa. The owners of this system charge Alliant Energy, and in turn its customers, to use the transmission system in Iowa.
Alliant Energy’s Iowa electric customers are receiving a refund because of a recent complaint filed against the owners of the transmission system. The complaint asserted that the transmission owners charged too much for their Return on Equity from 2013 – 2015.
In 2017, the Federal Energy Regulatory Commission (FERC) approved the refund for a portion of the costs charged by the transmission owners.
DescriptionCustomers will see a separate line item on their bill labeled “Regional Transmission Service Refund.”
TimingThe refunds will appear on customer bills from May of 2017 through the end of 2017.
The refund equates to a $3.60 bill credit per month through the end of the year for a typical residential customer, based on usage of 750 kWh per month.
Our plan to distribute the refunds takes several items into account, including projected energy usage, demand and how much each class of customers has already paid for transmission service. This plan was reviewed and approved by the Iowa Utilities Board.
The total breakdown among all customer classes shown in the table below are the refund amounts:
|Customer rate class||Refund total|
|Large General Service||$16,437,839|
