Sun’s out = heavy AC load?
Doing any grid 100% solar needs a lot of storage, but there’s gotta be a perfect point that mostly shaves peaks really nicely.
(Yeah yeah, it can be cloudy and hot+humid, but still)
- Manuel_D 3y agoDemand typically peaks in the evening, around 9pm. This is right as the sun sets, where solar is tapering off. It's not "shaving peaks" about half your electricity consumption (including peak consumption) is going to happen during periods of non-production.
- ZeroGravitas 3y agoAnd yet their on-peak times in the summer ends at 7pm: > Shift some of your summer energy usage away from the on-peak time periods (2-7 p.m., Monday–Friday, June–September, excluding holidays).
- Manuel_D 3y agoDemand shifting is just a long winded way of saying, "we can't generate enough electricity, you just need to stop using power at certain times of day." And it's easier said than done. Residential demand shifting, and some forms of industry (e.g. arc furnaces) can shift demand. But others cannot: the pumps powering your sewage system needs to work all day around. Same with data centers, and plenty of other industries.
- nicoburns 3y agoRight, but we don't need to shift all demand for it to have a big impact on the amount of storage required. Any demand shifted is energy that doesn't need to be stored.
