On February 16, Ideal Energy announced its estimate that the decision of the Iowa Utilities Board to accept a proposed rule change from Alliant Energy will cause a 70% or greater reduction in solar installations for residential and light commercial customers in Alliant Energy’s Iowa service territory.

Per Ideal, the new rules are scheduled to go into effect on April 1st of this year for Alliant Energy’s 488,000 electrical customers across Iowa.

Developed in response to the Board’s 2016 request to Iowa’s utilities to develop net metering pilot projects, Alliant Energy’s new net metering rules will add a cap on how much solar generation is eligible for net metering, based on an percentage of a customer’s annual energy usage the year prior to the solar installation.

According to Ideal, a typical small business and residential customers will see a 65-70% reduction in net metering eligibility.

Channing Congdon, Director of Design at Ideal Energy, remarked: “This ruling effectively ends residential solar for Alliant.”
