Electricity customers of Alliant Energy Corp. in Wisconsin will pay a little more for power in 2018 because the cost of fueling the Madison company's power plants is expected to go up.
The state Public Service Commission has approved a fuel adjustment increase of 0.49 percent overall, which will provide the company another $5.7 million in revenue next year.
For residential customers, the increase will be 0.38 percent, or about 37 cents a month for the typical household, Alliant said. That will raise the average monthly residential electric bill from $96.64 to just over $97, utility spokeswoman Annemarie Newman said.
Alliant, with utility subsidiaries in Wisconsin and Iowa, covers about one-third of the state of Wisconsin and serves a total of 960,000 electric customers and 410,000 natural gas customers.
