Californians pay the second-highest electric rates in the U.S. after Hawaii, according to the most recent figures from the U.S. Energy Information Administration. A number of factors go into those rates, including wildfire mitigation costs. PG&E in particular has attracted the ire of California customers for its frequent rate hikes within the last year.
Baked into those bills is the return on equity, money meant to compensate shareholders for the risk of doing business. These shareholder return rates are set by each state’s utility regulators and hover nationally around 10%. If approved, PG&E’s rate would be 9.93% (down from 10.28%), Edison would be 9.98% (down from 10.33%), and San Diego Gas & Electric would be 9.88% (down from 10.23%). These rates are not automatically guaranteed – utilities can fall short of this return if they don’t keep down costs, such as project overruns or unexpected lawsuit fees.
A small change in this rate can be a difference of millions of dollars for ratepayers. The return is a percentage of the rate base, the total value of a utility’s assets it can earn a return on; this includes projects such as building a new power plant, for example. The rate bases for California’s three large investor-owned utilities have steadily grown each year as they add new customers and projects, increasing the amount that shareholders can receive.
PG&E, for example, had a 10% shareholder return in 2023, a possible return of about $125 million. Had it been 1% lower, the potential return would have been $12.5 million less.
“The proposed cost of capital decision needs refinement to better reflect California’s unique risks and market realities,” said Edison spokesperson Jeff Monford. “Making those refinements in the final decision will enhance SCE’s ability to finance essential infrastructure projects for a more reliable, resilient and ready electric grid.”
PG&E spokesperson Jennifer Robison echoed this sentiment, saying the decision “fails to acknowledge current elevated risks to help attract the needed investment for California’s energy systems.”
