Public Service Commission Investigates Net Metering in Wisconsin, Solar Owners Await Changes
07 November 2026
The Wisconsin Public Service Commission (PSC) has opened a formal investigation and comment period on net metering, the policy that allows solar owners to receive bill credits for electricity they export to the grid. The move came after investor-owned utilities submitted proposals that, if enacted, could significantly alter how rooftop solar is compensated.
A Holistic Review of Net Metering
The PSC's investigation, which opened in March 2024, aims to provide a comprehensive review of the current net metering framework. The commission has directed staff to consider a number of critical elements as part of the inquiry. These include:
- Conducting a cost-benefit analysis to assess the financial impacts of net metering
- Assessing the value of solar in the state, potentially including a value-of-solar study
- Analyzing whether a cost-of-service approach could provide an equitable framework
- Evaluating the effect of solar adoption rates on net metering and the broader grid
- Investigating sustainable rate designs and incentives for parallel generation customers
Critically, the commission is also focused on understanding the implications of any changes for low-wealth and marginalized customers. Ensuring the policy advances state goals around environment, economy, and equity is an explicit focus.
Key Implications for Solar Adoption
Net metering plays a pivotal role in shaping the economics of rooftop solar for Wisconsin home and business owners. The policy allows those who generate more power than they use to receive credits on their utility bill. As a result, solar adoption benefits far surpass the solar worthiness of a building by boosting the bill credits and reducing the long-term payback period.
Any significant changes to this policy could increase or decrease the economics of solar adoption. According to advocacy group RENEW Wisconsin, the current framework provides critical economic incentives that drive investment in local solar. It argues that a net metering system can boost solar investment through capital and loans, benefiting residential and commercial solar customers as well as solar industry job growth and energy independence.
At the same time, some utilities and stakeholders have raised concerns that the current net metering design could place an unfair burden on customers without solar. They argue a shift toward a cost-of-service model could help achieve rate equity and long-term grid reliability.
Utility Proceedings Set the Stage
This isn't the first time the PSC has revisited the potential for a major shift in solar net metering. In the 2023 rate case for Madison Gas & Electric, the utility and its customers engaged in a significant debate over proposed changes to solar contributions after MGE put forward a new tariff structure.
Originally, MGE's proposal would have closed the net metering program to new participants - first on July 1, 2025, and later in a revised filing on September 1, 2024 for applications and December 31, 2025 for installation and interconnection completion. Customers and the PSC argued the proposal did not meet the public purpose of net metering while ensuring reliability.
Instead, the commission settled on a Parallel Generation-Hourly Export (PG-HE) tariff. This new option allows customers to balance billing on an hourly basis: surplus export earns credits at retail rates, while deficits import at the utility's avoided cost. The final order was deemed more reflective of solar's true value.
A Long Road Ahead
While the updated tariff helped, it also raised fresh questions about how to value and incentivize next-generation distributed energy systems. Following extensive stakeholder comments on the 2023 proposal, the PSC decided to conduct a deeper review due to the policy's far-reaching impacts on rate equity, grid reliability, and clean energy progress in the state. Regulators acknowledge this will be a rigorous process without a firm timeline.
Notably, consumer advocates and solar developers argue the net metering question is closely tied to broader reforms in energy efficiency, grid modernization, and landmark climate policy goals. They contend that without envisioning the future of solar, a true value-of-solar analysis is incomplete. Meanwhile, challengers note the growth of solar PPAs as an alternative arrangement - and raise questions about the downside risk to utilities if customers were to reduce consumption further. Local media may follow these perspectives.
The bottom line is that solar operators, utility customers, and concerned citizens alike should follow the PSC's net metering proceedings closely in the months ahead. The final decision will undoubtedly shape the trajectory of rooftop solar and energy equity in Wisconsin for years to come. The current open comment period will help ensure all voices are heard before the PSC reaches its final decision.
