California is planning for TOU (Time of Use) pricing for electricity that matches up with renewables like solar and wind:
From late morning until the sun sets, California produces a significant amount of solar power; and the future for solar is so bright, we’re reaching for our shades. With TOU pricing, we can shift demand to match up with the abundant solar electricity we produce – making the cheapest price windows for TOU rates likely from 10 AM until 4 PM. The good news is, the success of clean energy programs in California over the past decade means we’ll be able to meet peak demand by simply re-aligning our energy use to synch up with plentiful, clean, and cheap electricity.
Starting January 1, 2019, after a period of study, public outreach, and education, California’s large investor-owned utilities (Pacific Gas and Electric, San Diego Gas and Electric, Southern California Edison) will switch households to time-of-use (TOU) electricity pricing.
This simplified rate structure rewards customers who shift some of their electricity use to times of the day when clean energy is plentiful.
Why would you run the dishwasher at 6 PM, for example, if it were cheaper to wash the dishes overnight when wind energy is abundant and cheap?
The last line is an actual quote.
Why? Because you want clean dishes? You can’t sleep with the dishwasher running?
Do you want to be able to afford electricity for showering, laundry or charging your electric car?
Then stay home in the middle of the day (but only when it is sunny). or only do those things when it is windy!
If you don’t you know they will punish you with grotesquely high electricity rates.
