Grid scale battery storage only became practical in the last few years. Now there are a lot of projects under way but they'll take time between approval and completion. One notable example from last week:
"Vistra approved to build a grid battery bigger than all utility-scale battery storage in the US combined"
The past month has been littered with news of exceptionally large battery storage developments, yet none in the world can compare to the news that Vistra’s permit to expand an energy storage system under construction at its natural gas-fired Moss Landing generation station in Monterey County, California to 1,500 MW/6,000 MWh has been approved.

- dehrmann 6y agoCentralized is cheaper to install and maintain, though. Rather than dispatching an electrician to a home every time its battery has a problem, a farm keeps electricians on-staff and replacement parts in-stock. Installation is cheaper for the same reason.
- grandinj 6y agoUp to a point yes. Decentralised is also nice if co-sited with substations because the utility can use it to flatten out spikes/dips and generally make other parts of the infrastructure happier, which reduces maintenance costs on those other parts.
- SpicyLemonZest 6y agoWhen the article calls this a "landmark plan", they mean it's an experimental new plan. Power technologies need to be well-tested, known to be reliable and efficient, if they're going to be deployed at scale.
