At its November 7 open meeting, the Public Service Commission of Wisconsin (PSC) took up rate increase proposals from both WE Energies and WPS utilities. The PSC either authorized or provided minor modifications to the utilities’ proposed plans for future costs, financials, and rate increases. A Wisconsin Public Radio article summarizes the results and reactions to the PSC’s decisions.
RENEW participated as a party in these rate cases and concentrated our efforts on utility policies, programs, and pricing that influence clean energy adoption for its customers. Although the PSC authorized some significant rate increases, it also authorized clean technology improvements that RENEW proposed and supported in these cases.
As it relates to WE Energies, RENEW has been working to eliminate the utility’s requirement to install two meters for its net energy metering customers, a cost-prohibitive requirement for people considering rooftop solar. WE Energies initially proposed allowing single bidirectional metering no sooner than January 1, 2026. RENEW pushed back on this implementation date, requesting a January 1, 2025 implementation date. The PSC ultimately authorized a compromise of June 1, 2025.
For both WE Energies and WPS utilities, RENEW also proposed an increase to the threshold for commercial customers to install larger “behind-the-meter” (BTM) distributed generation (DG), which, in many cases, is rooftop solar. RENEW proposed an increase from the current 1,000 kilowatts (kW) maximum to 5,000 kW, which is in line with other Wisconsin utilities as well as federal guidance. Although the utilities disagreed with RENEW’s proposal, the PSC ultimately agreed with RENEW and required these utilities to increase their commercial BTM offerings up to 5,000 kW by 2025, allowing commercial customers to increase their energy independence through clean energy.
Vote Solar also provided testimony regarding utility-avoided costs in relation to more equitable pricing for these larger commercial DG systems, which RENEW supported. While the PSC did not authorize pricing changes in these rate cases, it agreed to investigate these issues further in separate cases in the future.
We also saw changes with the EV pilot program and the Bring Your Own Device (BYOD) smart thermostat program for both WE Energies and WPS utilities. In the Electric Vehicle rate case, RENEW supported several changes to benefit EV owners.
- Increasing a bill credit cap for home charging beyond the initial proposal
- Allowing customers to own their charging equipment
- Utility collaboration on developing a model for a multifamily dwelling EV charging program
- Maintaining an EV charging rate of 50 kW to ensure the businesses can access a bill credit
The PSC kept the new home charging bill credit at its initially suggested rate of 400kWh and increased the threshold for businesses to access a bill credit to 150kW, going against our recommendations. The PSC did, however, approve the use of customer-owned charging equipment and the need for utilities to develop a model for EV charging at multifamily dwellings, like apartment buildings.
For the BYOD potion of the rate cases, WE Energies requested that their program be identical to Madison Gas and Electric’s original BYOD program with a participation cap of 7,000 devices (or homes). These programs allow utilities to connect to thermostats and adjust temperatures to lower energy use during periods of high use. These programs help save energy, control costs, and help reduce emissions.
RENEW requested a higher participant cap in the smart thermostat program due to We Energies and WPS’s larger customer base. We also asked for increased collaboration to explore future technologies, an earlier implementation date for these programs, and data reporting on participation and savings. The PSC raised the cap to 64,000 participants for WE Energies and 24,000 for WPS, mandated collaboration with RENEW to explore future technologies and ordered data reporting as requested. The PSC set the implementation date for these programs for January 2026 instead of moving up the deadline to the summer of 2025 as suggested by RENEW.
All in all, RENEW staff were able to achieve some focused and notable victories in these cases! Below is a summary of these clean technology policy improvements that will occur starting in 2025:
Applicable to WE Energies and WPS:
- Large BTM DG systems are currently limited to 1,000 kW, but after RENEW’s testimony and recommendations the PSC will increase to 5,000 kW systems
- PSC will take up several utility-avoided cost issues in new dockets
- PSC authorized new BYOD smart thermostat pilot programs
- PSC authorized improvements to both residential and commercial EV charging programs
Specific to WE Energies:
- PSC authorized a compromise for bidirectional metering for net energy metering customers, with an implementation date of June 1, 2025.
