Wisconsin utility looking to move forward with 1,000MW solar buildout

S&P Global Market Intelligence ($):

Alliant Energy Corp. said Feb. 21 that it is likely to file in the second quarter with regulators its rate plan covering the first tranche of a 1,000-MW solar buildout that will continue through 2023 in Wisconsin.

The Madison, Wis.-headquartered utility holding company said it is also “watching closely” legislative initiatives that suggest that neighboring Iowa is “early in the process” of building out solar generation in a state where regulated utility subsidiary Interstate Power & Light Co. already has a significant wind generation fleet.

“We’re putting renewable energy to work for our customers by advancing our renewable energy investments and preparing the energy grid for more distributed energy resources,” Alliant Energy Chairman, President and CEO John Larsen told analysts in discussing the company’s fourth-quarter 2019 financial results.

Alliant serves more than 965,000 electricity customers in Iowa and Wisconsin and meets a summer peak demand of 5,459 MW. Alliant’s regulated utilities own 12 wind farms with 1,890 MW of capacity. The company also serves 415,000 natural gas customers.

Larson noted the recent completion of the 200-MW Whispering Willow Wind Farm – North (New Wind) project in Iowa. “We now have nearly 70% of our planned 1,000 MW of new wind placed into service for our Iowa customers,” Larson said. “We are on track to complete the balance of this plan by the end of this year.”

The company has said it will also be adding 730 MW of gas-fired generation this year to “complement renewables.” Larsen said the West Riverside Energy Center in southern Wisconsin is over 98% complete and expected to be in service in the coming weeks.
