I don’t think people realize just how big of an impact batteries are already having on the grid. In just a few years, batteries have completely taken over ancillary services in ERCOT. The same will be true everywhere else soon. It’s far more efficient to provide ancillary services with batteries than to keep a significant portion of thermal capacity on the sidelines.

Batteries are reshaping ERCOT’s ancillary services procurement Battery generation capacity has made up 50%+ of awards for reg up and responsive reserves since 2022. In these, coal and gas regularly account for <20% of capacity. While ECRS is more restrictive, batteries have

If batteries have taken over ancillary services in ERCOT, then new battery additions either won't get this revenue stream or they will compete with existing batteries. Does it mean further battery additions in ERCOT are unlikely?

Lots of batteries are still getting installed, but they’re longer duration and geared towards arbitrage. Ancillary service revenues (and costs) will continue to fall.

Batteries starting to significantly impact in Australia, too This from Western Australian grid

Last night, Good Friday Eve (is that a thing?), utility batteries in Western Australia were in double digits for 3 hours peaking at 13.3% battery facilities share of WA WEM supply Actually, 15.1% @ 6PM if you add Cunderdin hybrid solar/battery export reported as a solar facility x.com/ProfRayWills/s…
OpenElectricity graphics based on AEMO data (https://explore.openelectricity.org.au/energy/wem/?range=1d&interval=30m&view=discrete-time&group=Detailed) shows at 6PM, 13 minutes after sunset on 17 April 2025, Cunderdin was producing ~46 MW of solar - that's stored solar exported from it's battery

Over the past few days ~ 2-4 GW of batteries participated on ERCOT, meanwhile: there is also +3GW of bitcoin load participating in demand response.

What "hogwash"! Again, you are attempting to misdirect people into believing how well batteries are supposedly doing. Of course, this is an outright lie. The heavy lifting for ancillary services remains hydrocarbons supported by nuclear baseload. Batteries main role is to

So interesting I am just amazed at how useful batteries are and can't wait to see continued implementation onto the Utility Grid.

I anticipated this shift—batteries now dominate ERCOT reserves. Big step for grid flexibility. Will be interesting to see how this impacts future investment decisions.

ERCOT, or the Electric Reliability Council of Texas, is the organization responsible for managing the electric grid in Texas, supplying power to over 25 million customers and overseeing about 90% of the state's electricity load. It operates independently from federal regulations

Are the batteries entirely domestic or do they partially or wholly come from China?

Figuring out acronyms ... ERCOT Contingency Reserve Service (ECRS) Now, what does it do? Contingency Reserve - seems to be highly dependable and able to come on line should a unit drop or fail to come on line?

Made me think of freeway traffic congestion, how additional lanes was thought to be the answer. In this maybe we’ll have a different outcome, but 10 years ago AI wasn’t a thing, seems the more efficient we make the grid it is quickly taken advantage of.
