Huge, this helps wean Poland off of coal.

and industry

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.

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?

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.

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

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.

Which battery technology and where are the sourcing it?

> BYD Energy Storage will supply the battery technology.

third sentence...

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

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

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.
