We didn’t have digital controls when they were designed, so you couldn’t use GPS or atomic clocks to synchronize frequencies, you just needed to have a single source of coordination. Those coils were manually controlled till not long ago.

Now we should be able to use some kind of small gas turbine with a igbt rig for synchronization, much like they do with wind turbines.

People often don’t appreciate how far we’ve come over the past 2 decades, and how utterly manual and brute force we were until very, very recently.

It’s why “smart grids” are talked about a lot recently, even though it doesn’t mean much for the layperson. But for the people actually working in the industry, it matters a lot and can be a huge benefit

Yeah, but the utility’s management… Holy shit.

They could trivially save billions a year just by adding intelligent load coordination and shifting for evs, you sign up and you save a few pennies a kwh, and in exchange they can steer load away from shortages and towards surplus. It’s 1990s technology.

But management at places like Pge are just jobs programs for Newsom to sell to sew up the 2028 primary, which hilariously backfired for him (though im sure he cut a decent deal).

Most Ev loads are almost instantly dispatchable, it’s an absolute no brainer, even if we aren’t trying v2g, at least control when they charge.

Ah makes sense, I forget how old a lot of that infrastructure is. I do a lot of work for our local ski resort, they have a 12mw generation plant for their snowmaking system that can backfeed the utility if needed, and they’re sync setup was basically two blinking lights that you had to visually time just right to close the switch and pray you didn’t screw up lol.

That is hilarious, but also I can 100% picture it in my head, and it’s not that far off from what the big machines did until recently, and pretty sure some still do.

BTW, there was money both in 2010 and 2021-2022 that was literally supposed to replace all those linkages with something less ancient, even for small things like yours.

My understanding is the money ran out halfway or so, maybe less, and even a lot of the big stuff didn’t get done, they kept fighting on how to do it and the details, everybody wanred standardized on their system, and in the end very little actually happened.
