2.4 gwhr is a monster of a battery.

For reference the UK has about 7gw output of battery (assuming all on at the same time. I don;t have the capacity though.) The UK is one of the more mature grid battery places in europe.

Greenvolt Group has started construction of a 600 MW/2.4 GWh battery energy storage system (BESS) in Poland, with commercial operations targeted for the end of 2027.

Huge, this helps wean Poland off of coal.

Which battery technology and where are the sourcing it?

shortcrct 1 hour ago | |

The article says the batteries are sourced from BYD, and it's likely lithium iron phosphate batteries.

> BYD Energy Storage will supply the battery technology.

third sentence...

Article doesn't mention but says the company is BYD Energy Storage which apparenly uses Lithium Iron Phosphate (LFP) battery technology (specifically, Lithium Iron Phosphate / LiFePO₄

Meanwhile the US is doubling down on fossil fuels because… reasons.

The BESS market is doing OK in the US. Politicians will come and go but the fundamentals of BESS are solid, so I don't see why the installed base won't keep increasing in the US.

Battery storage capacity averaged 70% growth over the last three years - https://www.eia.gov/todayinenergy/detail.php?id=67925

> During the first six months of 2026, operators added another 8.3 GW of battery storage capacity, reaching nearly 52 GW of nameplate battery storage capacity

What's a "GW of battery storage capacity"? Do they mean gigawatt-hour? (sidenote: how scary that the DoE is the one making this error?)

How much faster would it go if the feds were helping things along instead of actively hindering?

I don't know about other states, but Texas has about 18GW of BESS, already (https://www.cleanview.co/power-projects/operating/battery-st...). We're planning another ~177GW (https://www.ercot.com/files/docs/2026/04/16/ERCOT-Monthly-Op...).

YMMV depending on where in the US you are. California has like 10x'd it's battery storage in a couple years, to the point where it's the main source of electricity during some time slots where we used to be dependent on natty gas.

Edit: although it looks like in recent days, fossil fuels reign supreme once the sun goes down. I guess we don't have enough batteries for the current heat wave

Texas also has large amounts installed and growing.

We have one of the world's largest BESS installations in California. Calm down.

Not really. The market is still moving quickly towards renewables. It's only some conservative politicians in the US that are making noise about fossil fuels, not the market.

The market does not fix the administration paying wind projects billions of dollars to stop development.

The market does not fix the administration forcing coal plants to stay open even when they are losing money.

The market does not fix the administration cancelling grants for clean energy projects and subsidies for electric cars, and adding tariffs to solar panel imports.

And US car manufacturers are enthusiastically moving away from their efficiency goals. That market is not moving quickly to renewables.
