Adding reserve storage to the grid is a good idea. That said I'm not so sure about batteries at this scale. It would probably be more efficient to pump water uphill into a reservoir to store power and tap power by letting water out through hydro electric generators. There are a few other ways it could be accomplished as well such as giant flywheels. Think a fly wheel as large as a house and weighing in at several hundred tons.

Pumped-storage hydroelectricity is far too mainstream to get people excited, though. It is hard to get huge new subsidies from the government and accolades from the environmentalists for approaches that are already in wide use.

Greenies have been very careful to demonize hydroelectrics around the world. Muh environmental and natural beauty impact and all that. Though it's the best option for raising the 3rd world up from their fuckass status.

These days I just assume that Greenies are actually serving the globalists and hydro has been specifically suppressed, because it's too effective and would keep niggers in their own countries.

The main advantage of the Hornsdale Power Reserve (Tesla battery), is its ability to provide power in milliseconds, before other backup power comes on.

First, the power plant responded to the grid frequency challenge before the offending coal plant actually finished tripping itself from the power grid. That’s not like telling the future, but it’s so fast you’d start questioning things.

And secondly, it finished its work of stabilizing the grid and shut back down before the regular backup plant even started its work. Because of the slower nature of fossil fuels generator, literally spinning up a massive turbine, they’re designed to deliver far more energy than is needed to the power grid. As a form of insurance.

That said, hydroelectric storage is a great conventional means to store large amounts of energy, especially in off-peak times. Recently a wind power station of this type was built near here that combines hydroelectric storage with the notoriously unreliable wind power. It's supposed to be able to switch from storage to 16 MW generation within 30 seconds and have a storage coefficient of efficiency of 80%.

Those ideas still wouldn't be as quick as an actual battery bank. Also, alot more moving parts means alot more system maintenance.

Lithium batteries only have a life time of a few hundred cycles so your looking at replacing the entire stack completely in something like 2 or 3 years.

There’s one somewhere that’s basically flatbed train cars full of concrete blocks, excess power pulls them up a hill, and then they generate power coming down.

sounds interesting, do you have a link for that?
