On Thursday, July 24, 2025, the Public Service Commission of Wisconsin (PSC) determined how the state would move forward with its investigation into net metering, which was opened in response to net metering changes proposed by Madison Gas & Electric and Alliant Energy.
Initially, a Wisconsin Value of Solar Study (VoSS) was expected to be a part of the overall investigation. PSC Chairperson Summer Strand indicated during the July 24 open meeting that she was content with the VoSS information already provided in the docket, and that a Wisconsin-specific VoSS effort would require more effort than it was worth. Commissioners Kristy Nieto and Marcus Hawkins ultimately agreed with this path forward.
Though a Wisconsin-specific VoSS won’t be a part of the investigation going forward, the PSC still plans to investigate and gather additional data and information about the state of rooftop solar in Wisconsin to help guide policy decisions. We are encouraged by their continued interest in establishing clarity and data on solar installations in Wisconsin. RENEW also hopes that the PSC considers the quick phase-out of federal tax credits for residential rooftop solar as they review installation trends moving forward.
The commissioners made it clear that they will include a review of adoption rates, an evaluation of net metering options and rate designs, and the expected impacts of rate designs on customers in their investigation. In relation to rate design options, the commissioners were also interested in the incorporation of time-of-use rates and other customer technologies, such as batteries and smart thermostats, and innovative programs, such as behavior demand response and virtual power plant options for the future.
RENEW Wisconsin participated in the process as it related to creating the parameters for the VoSS and will continue to offer input whenever we have the opportunity. We will also inform members and supporters alike when there are opportunities for the public to participate in the process.
