California's Electricity Problem

This research investigates the increasing electricity costs in California, focusing on investor-owned utilities (IOUs), publicly-owned utilities (POUs), and community choice aggregators (CCAs). It identifies that IOU and CCA rates have significantly risen since 2019, while POU rates have remained relatively stable. The study points to rising transmission and distribution (T&D) expenses, especially those related to wildfire mitigation, as a primary driver for IOU and CCA cost increases. POUs, with lower wildfire risks and smaller territories, have experienced more modest cost increases. CCAs often mirror IOU prices due to shared T&D infrastructure costs and Power Charge Indifference Adjustment fees, which can negate generation cost savings. The findings highlight the divergence in electricity prices among power providers and the need for proactive grid management for affordability and reliability.
