The growth is also prompting a face-off between the public programs and California’s three biggest private utilities, including Pacific Gas & Electric. In the dispute, both sides have suggested their ratepayers are getting a bum deal in how the state has set the rules for this new era. For the public programs, the outcome has high-stakes implications because their customers could end up paying considerably more to offset the growing costs for excess power that the utilities contracted for but no longer need.
The public programs, typically known as Community Choice Aggregation, or CCA, agencies, have grown to control about 5 percent of the state’s electricity market, a new study reports. But both utilities and other experts say that number will increase markedly as other communities join the trend.
