Less curtailment of renewables and lower customer bills are some of the benefits expected from demand flexibility. The rulemaking follows a white paper last month proposing opt-in dynamic pricing in California.
The California Public Utilities Commission has voted 4-0 to institute a rulemaking to advance demand flexibility through electric rates.
Demand flexibility would allow consumers to reduce or shift their electricity use at times of peak demand in response to a price signal or other incentive, the Commission (CPUC) said in a news release. Enabling the use of price signals in this way is known as dynamic pricing, or “sending prices to devices.”
The demand flexibility measures to be considered in the rulemaking would reduce curtailment of renewable generation, said the news release, while enhancing electric system reliability, reducing system costs and customer bills, and enabling electrification of buildings and transportation. The measures would allow participation in demand flexibility by customers, community choice aggregators and direct access providers.
A white paper and staff proposal on opt-in dynamic pricing released last month by the CPUC’s energy division additionally sees the approach as a way to enable fair compensation for the services provided by distributed energy resources.
The white paper “offers a promising approach to scaling demand flexibility,” said CPUC Commissioner Darcie Houck, in an online workshop Thursday that discussed the paper. Houck lauded the “tremendous time, effort and expertise” put into the white paper, and the leadership on demand flexibility from Aloke Gupta, a supervisor in the CPUC’s energy division.
Gupta said in the workshop that the CPUC will consider establishing policies and programs to add a “vast amount of flexibility.” He said the CPUC’s order instituting a rulemaking “calls out the six specific strategies” described in the energy division’s white paper “as a basis for enabling widespread adoption” of demand flexibility solutions.
Noting that California aims to achieve net zero carbon emissions by 2045, Gupta said that alongside three strategies seen as key to achieving that goal—decarbonizing the power supply, electrifying end uses, and reducing demand through energy efficiency—he would like to elevate demand flexibility as another strategy “on an equal footing.”
Houck encouraged “all interested stakeholders” to engage in the rulemaking proceeding, as “we rely on the considerable knowledge and expertise of all of the parties involved, to help achieve the ambitious goals we have collectively set for California.”
The deadline for submitting opening comments will be 30 days from the CPUC’s July 14 vote to institute the rulemaking, said Andrew Magie, a CPUC regulatory analyst. The docket number is R.22-07-005.
A recording of the workshop will be made available.

With smart appliances, such as dishwashers, washing machines, electric dryers, window air conditioners that could be filled or pre-set to work, once the utility gave the signal to start, could use up the excess power provided by renewables. Leaving home, in the morning, with the clothes washer set to “Signal Start” sometime during the day or the dishwasher set to “signal start” or even the air conditioner set to “signal start” and be charged a lower rate on the electricity and take advantage of mid-day excess power would be great if manufacturers would provide such internet connected programming. next the Electric cars parked in the garage could be plugged in but only charge during peak periods of excess power. In fact. even power walls could be charged with the excess power with cheaper electricity to then be released at Peak Demand Times in the evening. Getting the signal will require appliance that can use the signal to work. Right now, we only have smart thermostats that run whole house air conditioning cutbacks during high demand times and not “start Now” commands to use the power now. I do these things now manually based on my grid tied inverters output or my battery state of charge storage reserve. it would be nice if the utility could take control as save us all a few dollars in the mix.
