RPS Compliance

The Wisconsin Renewable Portfolio Standard (RPS)

2005 Wisconsin Act 141 (Act 141) set a statewide goal of 10 percent of total Wisconsin retail sales of electricity from renewable resources by 2015, and also established requirements for all 117 electric distribution utilities, or “electric providers” as they are legally defined. Act 141 set baseline percentages for electric provider requirements, based on their average renewable energy percentages observed over the 2001-2003 period. 

For the initial compliance years (2006-2009), electric providers had to maintain their baseline percentages. During the 2010-2014 period, they had to increase their renewable percentages to 2 percent above baseline. In 2015 and thereafter, they have been required to increase their renewable percentages to 6 percent above baseline. In order to achieve compliance, electric providers retire renewable energy certificates​ that represent renewable energy generation.

​Biennial Reports

Wis. Stat. § 19​6.378(4r) requires the Commission to biennially​ evaluate the impact of the RPS on the rates and revenue requirements of electric providers, and compare that impact with the impact that would have occurred if renewable energy practices of electric providers were subject to market forces in the absence of the requirements of the RPS.

Annual Reports

​The Commission evaluates electric provider compliance with the RPS annually. Electric providers must file information demonstrating their compliance for each compliance year by April 15 of the following year. Electric providers use the Midwest Renewable Energy Tracking System​ to demonstrate RPS compliance.

Renewable Energy Resource Reports

Commission shall prepare a report stating whether the state has met a goal of 10 percent of all electric energy consumed in the state being renewable energy. No ongoing report is required since utilities achieved this goal.  Per Wis. Stat. § 196.378(2)(a).
