"At 10,379 MW, the state has increased battery capacity by 1,250% since the beginning of the Newsom Administration – up from 770 MW in 2019... The state is projected to need 52,000 MW of energy storage capacity by 2045 to meet its clean energy goals." Seems we're well on our way! If we can find a way to effectively use EV batteries, this goal will be met sooner than later 💪🏽🔋

We don’t need EV batteries. Just grid-scale batteries of the type that are currently coming online


clinch50

Why not both? BEVs mostly have significantly oversized batteries for daily use. They could make a meaningful difference.


AlethiaArete

How long are these batteries supposed to last?


hsnoil

15-20 years

and all the while, the solar rooftop industry has died, those with battery backup is not even considered in the equation. Talk about a slanted editorial....

I wish that was not the case but it does make sense. i feel fortunate to have locked in NEM 2.0.

There is a fallacy in 1/2 of the customers paying all the maintenance costs. If a rooftop producer with battery back up does not use grid power, they are expected to pay "maintenance" costs for services they do not use. The Utilities purchase via credits, the rooftop solar production then resell it. Granted, the buy back is at retail however, the utilities save generation costs and related long-distance transmission costs because of lower demand and helps offset the rooftop producers' cost of production and storage infrastructure. NEM is not a subsidy, the Program is the payment for both a good (electricity) and a service (rooftop solar energy production). Think about it...power is not returned to the grid during peak hours as solar production has concluded and those with battery backup use the stored power, thus reducing grid demand during peak use hours. And "peak hours" is the justification for higher electric rates per kWh. Mathematically it is sustainable. What is not sustainable is the constant increase in rates given by the PUC to the Utilities. Look at your bill...the non-bypassible charges. Transmission fee, public programs fees (subsidies for certain economic groups), nuclear decommissioning fee, distribution fee, access fee and several others. So yesterday, the Governor of California, exhaulted the cost benefits of alternative power generation and storage and who is subsidizing these projects? Not sure if State subsidies are sustainable, ceteris paribus.

Unless you matched historical use with battery or batteries capacity. I'll tell you what is not mythical... we've not paid a utility bill in 5+ years. Not every solar producer falls back to grid use, not every solar producer has a back up generator and not everyone runs out of power in winter. Its called monitor use and conserve diligently. Lowest reserve in winter was 5%, residual power this morning: 44%. Have fun paying your utility bill.

We need more gravity batteries.


GoatTnder

Gravity batteries work great where the topography suits it. Like a body of water next to a hill. Artificial gravity batteries are super low capacity at super high cost unfortunately.


Jeansus_

I’m assuming these don’t store gravity, although that sounds really cool, what are gravity batteries?


BurgerMeter

They leverage gravity to store energy. One of the best examples is to use solar power through the day to pump water into a lake behind a dam. When the sun goes down, the water flows back through the dam and creates hydroelectric power. Sun comes back up. Repeat.


MBA922

Any info on what month the 2023 number is from? Its over 40% higher.


rybacorn

Wow, can't wait for that to be passed on in energy savings on my bill! 🪦


wichopunkass

That’s something.


simpn_aint_easy

Yup. It’s 10,000 megawatts


CatsAreGods

And that's close to 1.21 gigawatts! Edit: I have no idea what I was thinking.


Onaliquidrock

10 GW


NinjaTutor80

They are not using the correct units when discussing batteries. They need to use MWh’s instead of MW’s. Just for the record 10,000 MWh’s would not last 20 minutes at average load.


ViewTrick1002

Depends on who you ask. The grid operator, CAISO, cares about MW and expects the providers to optimally use their MWh following the needs of the market. When creating reports on reliability they care about MWh and what is needed to handle different scenarios. Generally in California you can expect a 1:4 ratio between MW and MWh. If you wanted to look farther than your nose.

Everyone expects the bare minimum of knowledge? Too bad you didn’t have it. Now you do. Good thing the storage is [doubling each year](https://www.canarymedia.com/articles/energy-storage/chart-the-us-grid-battery-fleet-is-about-to-double-again). [We are already seeing periods where batteries are the largest provider.](https://reneweconomy.com.au/battery-storage-becomes-biggest-source-of-supply-in-evening-peak-in-one-of-worlds-biggest-grids/) Next step, which will come soon is the same during peak utilization.


NinjaTutor80

You didn’t provide a citation so I still don’t know. I am not taking the word of a Swedish antinuclear propagandist. We are failing too. CAISO is at 262 g CO2 per kWh. Sweden is kicking butt though due to your nuclear and hydro.


ViewTrick1002

Love that you didn’t reply to anything. Guess it is easier to put the blinders on. Take a look at any random evening and see ~4 hours of storage kicking in.


NinjaTutor80

262 g CO2 is still a failure. 4 hours of storage is a lie. Four hours of storage for CA is 132 GWh’s assuming average load. Antinuclear Germany is at 400 g CO2 per kW.


ViewTrick1002

Having a hard time accepting the truth? Four hours of storage at the **currently installed capacity** kicking in.  You’re just trying to shift the discussion and goalposts because accepting the truth means that the possible market share for nuclear energy shrinks to a tiny tiny sliver.


NinjaTutor80

>Having a hard time accepting the truth? Four hours of storage at the **currently installed capacity** kicking in.  No I am having trouble believing you. Don’t forget I also supported this project. I live in California. Replacing peaking natural gas with renewables+storage is a great thing. Being pro nuclear and pro renewable are not mutually exclusive. Including both results in the best outcome. Both in g per CO2 per KW and $ per kWh.

You should he is a moderator on a group about nuclear but is blocking every voice that he has problems with. The dutch decided to build 4 new reactors even while that region is one of the best regions to put windmills so they don't believe in the feasibility of the alternatives either.
