And it's going to be the death of us.

Your home battery is no substitute for a proper electric grid maintained by a proper civilization.

This is a classic Band-Aid on a bullet wound. We know AI is coming for both our jobs and our electricity. And our solution is to retreat into our castles.

But we don't have castles we have moderately sized housing. We aren't Kings we are peasants. Just because we've got PlayStations and air conditioners doesn't mean we have become Kings.

It's that hyper individualistic hubris encouraged by the upper class and the elites so that we don't form communities that could cause them problems.

We should all fight the good fight to somehow fix our broken civilization, but in the mean time you can either sit in darkness during blackouts, or you can take action to make yourself self-reliant for home energy.

The number of charge/discharge cycles is unchanged with VPP. You just discharge a bit more during the evening with VPP. In exchange, they give you a large rebate, plus pay you premium peak prices for your juice. Nobody is fooling anybody.

The sheer tonnage of uninformed comments for this article, by people who obviously have no knowledge of VPP, could stop a herd of charging elephants.

Exactly. This is basically working like "peeker plants" work: providing a rapid boost in supply for a relatively short period of time.

The problem being addressed by this experiment is how to handle peak loads between 7-9 PM. For the purpose of solving that specific problem, a VPP delivers an amount power during those hours similar to a big hydro dam.

If your point is that one is big and gray and made of concrete and the other isn't, you're right. In fact, there are any number of differences like that between the two which are irrelevant in this context.

535 megawatts,

How many megawatt-hours? It might be half a nuke in terms of power, but that nuke can run continuously for weeks, months.

I think it's an interesting test from a capablity point of view. But it doesn't provide enough info to demonstrate the viability of home storage to bridge across intervals of renewable unavailability.

And as others have pointed out: What do the utilities pay homeowners back for that stored energy? Wholesale rates? Sorry. Not interested. I'd be better off keeping my power on my side of the meter. And offsetting retail rates for my own convenience. Not when some San Francisco multi-billionaires want to run their hot tubs.

The goal is to help with peak demand. Continuous isn't necessary for that.

On summer evenings when demand is high, it makes sense to sell some of your stored energy to the grid. PGE will pay you _more_ than the buy price this evening during peak hours. Keeping it on your side of the meter is dumb in that situation since doing so effectively shifts the period you sell from the evening, when you get paid a premium price, to the afternoon when PGE pays you almost nothing.

was 535 megawatts, equal to adding a big hydro dam or a half-sized nuclear reactor at a fraction of the cost

It's really not the same, for a number of reasons.

If you want to be pedantic, sure. But in a practical sense it is the same. It's a source of power that's available when the grid needs it the most.
