I’ve always wondered why the price of electricity on a time-of-use plan doesn’t match this curve. Our electricity is still “peak” pricing in middle of day at the bottom of the duck curve.
- nlh 3y agoThe duck curve chart is a bit misleading - it is "net load (or the demand remaining after subtracting variable renewable generation)", not total demand. Total demand is still highest mid-day, but there's enough solar being generated to lighten the net load. But your point is basically apt: As more and more at-home solar comes online, grid-demand WILL drop during the day and pricing SHOULD drop accordingly (but we all know it won't unless the utilities get a legislative requirement to do so).
- ZeroGravitas 3y agoDuck Curves that you see published are generally from the spring, (march to may in this case) when solar production is high and air-con demand is low. Time of Use rates are generally set anually, so need to account for the summer season.
- aidenn0 3y agoIt's an artifact of previous usage curves when PV was negligible. My utility has new peak hours starting around 6. I'm grandfathered in on the old plan for now, which is a difference of about $300/mo. in the summer.
- icegreentea2 3y agoIt is? Poking around it looks like peak rates are typically set from 5-9PM (https://www.pge.com/en/account/rate-plans/find-your-best-rate-plan/time-of-use-rate-plans.html https://www.pge.com/en/account/rate-plans/find-your-best-rat... for example).
