Columbia power plant near Portage (copy)

A major source of electricity for the Madison area comes from the coal-fired Columbia power plant near Portage, pictured above. The power plant is operated and co-owned by Alliant Energy Corp., which got the approval of state regulators last week to raise its rates because fuel costs are expected to increase.

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.
