even at the lowest demand, a large, grid-connected battery can only provide minutes of back up power, and that too for only a fraction of already low demand.
A storage battery is not a viable means of balancing demand and supply over a time period longer than minutes.
What's needed is not more batteries but better transmission, more hydro where possible and where hydro is not possible, more nuclear.
- bluefirebrand 6y agoWhen you're talking about lowest demand are you talking about for the whole grid? A city block? A building? A condo? And I agree. I worked in solar and storage for a while. It's not a replacement, it's just an extension. It works out ok for a battery system for a building but anything larger they just don't last long enough

For comparison, the Canadian province of New Brunswick has a comparable peak demand but fewer than a million people.
