Rate freeze for Alliant Energy’s Wisconsin customers

Our Wisconsin customers will see no increase to base electric and natural gas rates through 2020 under a proposal we filed today with the Public Service Commission of Wisconsin (PSCW). Customer rates will drop for the remainder of 2018 due to bill credits following a separate PSCW decision issued today.

“The rate freeze is a win for customers,” said John Larsen, president of Alliant Energy Corporation. “We’ve worked hard to hold the line on costs through 2020. It’s important to us to deliver cleaner power to families and businesses while keeping rates down.”

We reached agreement on the proposal with significant input and collaboration from the Citizens Utility Board (CUB) and Wisconsin Industrial Energy Group (WIEG). If approved by the PSCW, the plan would be in effect 2019-2020. A decision is expected later in 2018.

No rate increase proposed for 2019–2020

The proposal reflects our efforts to lower operational and fuel costs, along with expected tax savings from the 2017 Tax Cuts and Jobs Act. The plan includes our investments in generating electricity from cleaner and renewable sources.

Alliant Energy’s retail electric rates are among the lowest in Wisconsin.

Immediate bill credits through end of 2018

Under a separate decision today, the PSCW specified its formula for calculating customer bill credits as a result of tax reform. We are refunding a total of $36 million for electric customers and $4 million for natural gas customers in 2018.

Residential customers will see the following bill credits:

• One-time fixed amount credits during the June bill cycle
  • $22.92 for electric customers
  • $6.99 for natural gas customers
• Monthly credits calculated based on usage August through December
  • $4.11 for a typical electric customer using 700 kWh/month
  • $1.15 for a typical natural gas customer using 700 therms/year

Business customers will see bill credits as well. Amounts are approximate and subject to final calculation.

Iowa families and businesses to benefit from new energy law

Earlier today, Governor Kim Reynolds signed a comprehensive new energy law. Senate File 2311 helps Iowans save money, maintains the state’s leadership in renewable energy and promotes job growth.

“We applaud the Iowa Legislature and Governor Reynolds for supporting this new energy legislation and helping the state achieve its objectives outlined in the Iowa Energy Plan,” said Doug Kopp, president of Alliant Energy’s Iowa energy company. “This new law will maintain Iowa’s place as a national leader in renewable energy and energy policy.”

This law creates new opportunities for customers to see more clean energy, because energy providers can upgrade existing wind facilities to extend their useful life and improve their efficiency.

The bill also includes regulatory efficiency updates. One major update allows energy companies to use a forward-looking test year to better align customer benefits with energy investments. For potential and existing natural gas customers, the law lowers the cost for extending natural gas service.

In addition, this law will encourage savings for customers with energy-efficiency programs. Alliant Energy’s energy-efficiency programs will continue to help customers save energy and money.
