Relating to: Public Service Commission consideration of the social cost of carbon emissions and the recovery of costs relating to fossil fuel energy production infrastructure and transitioning to renewable resource energy production. (FE)

AB 858 requires Wisconsin's Public Service Commission to consider a minimum "social cost of carbon" of $185 per metric ton of CO2 emissions when reviewing energy certificates. It mandates that costs for expanding fossil fuel infrastructure can only be recovered from customers who directly benefit from that infrastructure, and prohibits passing transition costs to renewable energy onto ratepayers. The bill directly affects utilities seeking infrastructure investments and residential/commercial electricity customers paying rates. Key provisions ensure fossil fuel expansion costs are tied to specific beneficiaries while shielding customers from transition expenses during the shift to renewables.
