Credit Liberty Liberty Utilities has suspended a home weatherization program for its natural gas customers because of delays at the Public Utilities Commission in approving expanded energy efficiency goals for the state. Other electric and gas utilities say they could soon face similar choices that will affect their customers if regulators continue to leave the issue undecided. The PUC was supposed to have ruled by Feb. 23 on the utilities' plan for reducing the energy they sell by making homes and businesses more energy efficient from 2021 to 2023. These efficiency programs are designed to help people lower their energy bills and decrease carbon emissions. Ratepayers have to cover the up-front cost -- less than a dollar per month for average residents, through the System Benefits Charge on utility bills.
