What is wrong with this?
The better option is for the government/utility company to build out the required storage for a fraction of the cost.
Ex ante, sure. Right now, the existing batteries are a sunk cost the utility didn’t have to pay capital costs for. The right answer is to do both.
The former should be allowed to make their own decisions. I agree that the latter should probably be kept out of this: government is usually not very good at making these decisions. But alas, in many places they play a huge role in the electricity supply and distribution.
Yes, but that's how we arrive to local economical maxima that are much, much closer to the global minimum that to the global maximum. The personal decisions aggregate, after all.
You say Govt capital which only benefits private utlities and ALSO say govt/utility should to build out the storage. Not sure what you are trying to say. You sound pretty confused.
Variable pricing like this enables all sorts of cost saving technologies that bring down the cost of the grid and generating power for everyone, by spending a lot for a very short time, instead of building tons of extra large assets that sit mostly idle.
If somebody is providing a service that operates on the whole sale market, they deserve to get paid like all the other generators that are helping to keep the grid running in these times of need.
Not only do peaker plants make the most bucks/KWH, but they increase prices for all generation because of how auctions operate.
hell if I emptied my 30kw into the grid in my state/country at the most expensive time I'd earn AU$21.00
to earn US$150 means either HUGE battery capacity (and transmission capacity) or utterly rediculous power pricing... both mean really lousy power supply and grid design. I'm all for indipendance but the reality is we live in communities and count on the collective to rise us all up together.
that sort of profit is a clear warning sign of a broken community.
As more and more batteries are deployed the price swings will decrease.
It's not a "broken community" it's just end consumers being able to help out in times of great grid need and getting compensated fairly for it.
And it's not a sign of a broken community. Those batteries aren't making all that much money on a per-year basis. And the earlier batteries into the system are going to make the most money. The more batteries that get built the smaller the profits will be and the better the entire grid will be.
