This is an interesting data point. Grid scale batteries are a pretty big change in how grids are managed, things like "anticipating load" and starting up "peaker plants" to catch that load are mitigated by the ability to wait and see while the batteries fill in the gap.
- toomuchtodo 2y agoBatteries charge for free when renewables push spot prices to zero or negative and discharge when most needed and getting paid to do so; they comin’ for fossil gas generation that pays to burn (fuel) and spin (per hour O&M).
- _Microft 2y agoThey might even be paid for consuming power because that provides stability to the grid [0] in such a situation. Too little load causes the frequency on the grid to rise which is only acceptable within narrow limits.

- toomuchtodo 2y agoAbsolutely, there is no doubt that are stealing grid service revenue from spinning thermal, and they also provide black start services (jump starting larger generators when they go out through an isolated transmission path).
- applied_heat 2y agoI was under the impression that “grid forming” as opposed to “grid following” inverters were not a solved problem. Can you cite any battery plant with documented tests of energizing transmission or distribution systems?

Gambit Energy, owned by Tesla in Texas. Megapack supports grid forming in production (Hawaii and South Australia installations as well). “Virtual Machine Mode.” It is solved, which shouldn’t be controversial considering Tesla’s power control maturity.
- applied_heat 2y agoThanks for the link, looks like it is new development in the last 2 years which is the blink of an eye in utility timeframes.
