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.
Industry can electrify or sunset. “Work is hard.” The energy potential is well above the demand curve, just have to build the orchestration infrastructure (low carbon generation, batteries, transmission, district heating, flexible load demand response, etc). Enough sunlight falls on the Earth in thirty minutes to power humanity for a year, the inability to harness this potential energy is the problem being solved for. It's easy to go faster: simply direct fossil fuel capital and subsidies to the technologies I enumerate above. To not go faster is a choice. We could make different choices.
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
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.
> 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
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
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.
2.4 gwhr is a monster of a battery.

Huge, this helps wean Poland off of coal.

Which battery technology and where are the sourcing it?
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.

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
How much faster would it go if the feds were helping things along instead of actively hindering?
The government likes to get in front of a parade and pretend they are leading it.
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...).

Texas also has large amounts installed and growing.
We have one of the world's largest BESS installations in California. Calm down.
