Current Undergrounding Proceeding R.17-05-010 

In May 2017, the CPUC opened Rulemaking R.17-05-010 to consider changes to Electric Tariff Rule 20 in order to enhance the fair, efficient allocation of ratepayer funds to communities for the undergrounding of electric infrastructure. To date, Staff has hosted three workshops in 2017, 2019, and 2020 and collected extensive data from the utilities on their Rule 20A programs dating back to 2005. Furthermore, the CPUC Staff issued a Staff Proposal in February 2020 which detailed a comprehensive reform for the Rule 20 program.
