You have to build and maintain the storage.
Even if the electricity is free you'll have to replace your battery once in a while and at current prices that is ludicrously expensive.
It's cheaper to pay an already built fossil fuel plant to idle with spare capacity.
Give it a few years for battery technology and it may look different.
Give it a few years and I've got my hopes up for batteries.
The calculations showed the absurdity in gravity storage today, not batteries in the future.
I don't live in the US either.
I think the actual value on my bill is 2300kwh. But we can use 2700.
I can't find any source for $0.2/kWh. I used https://www.energy.gov/eere/analysis/2022-grid-energy-storage-technology-cost-and-performance-assessment and eyeballed the cheapest gravitational storage. PSH is still above $50. Well let's assume $0.2 per kWh per year and that half of it can be stored it's $270 per year in storage fee
My actual price for electricity is much lower than €600 per year, most of it is taxes and fees that does not get benefit from storage. Looking up the invoice from March i paid $0.07 per kWh, September was $0.01. Half of 2700 would be $95 using March price for the entire year.
We are spending billions, we must spend billions, but we have to spend them where it makes sense. Spending 270 to save 95 is insanity.
No. It's district heating and not included on the electricity bill. I live north of the Arctic circle and a house from the same year with a heat pump would use an order of magnitude more.
The example was meant to highlight the absurd costs despite ludicrously favorable assumptions.
Changing the words does not change the meaning.
Paying billions for mega projects to save millions on cheap electricity makes no sense.
Napkin math gravity battery Last figures I found are from 2022 the costs storing 1GW 24 hours is $150 per installed kWh
My apartment has an estimated electricity consumption annually of 2000kWh, I'll need to store half that for $150 per kWh in a structure that lasts 100 years without maintenance, then crumbles into dust and needs to be rebuilt. It would average out to $1500 per year.
My current electricity bill is about $600 per year.
This is a real problem for renewables.
You don't get paid when the sun shines, and you don't get paid for when it does not.
You had to pay for building the solar panels and maintaining them. Corporate greed aside none sane would like their tax money either to be spent on producing electricity when it's not needed.
Next step for renewables must be storage that is cheap enough for it to beat having fossil fuel on standby.
Corrupt people will be attracted to money.
A lot of otherwise honest people will become corrupt if they see others being corrupt and getting away with money and prestige from it.
A few percent of people will never be corrupted.
Yeah if I was just playing M+ I'd probably start a few weeks into the season when you can catalyse a 4 set and most of the rough edges have been smoothed out.
I can think of a dozen ways to make it worse, so it's clearly not "the worst".
Long term girlfriend: Yes, if she does not fuck other guys. Maybe I'll have issues with other things about the OF career, but I can't forsee it.
Marrying is primarily a financial contract on top of all the squishy feelings. Other than the usual check of living below your means an OF CC would have to prove: Does she have a plan on how to support herself if her OF career does not pay the bills?
North Scandinavia.
Most of the electricity here is hydroelectric that has been built many years ago so the power plants are paid off.
The price during summer is very low. In the winter especially the cold months is much higher with Dec-Feb being the peak.
The determining factor is still the capex for storing it. At $50 it makes no sense. At $0.2 it makes sense in some places. I don't know which assumption is correct, I expect to be wrong in 50% of the cases when I argue on the internet.
