A new wave of competition is coming to California, threatening to steal up to 80% of retail sales from the three big investor-owned utilities (IOUs). In a joint filing in late January, Pacific Gas and Electric Co. (PG&E), Southern California Edison, and San Diego Gas & Electric Co. (SDG&E) said that community choice aggregation (CCA) could cause huge amounts of “load defection.” Without the proper exit fees, the utilities are worried they could suffer big financial losses.
