Tesla battery proves a leading source of dispatchable power, AEMO says.Australia's electricity grid requires regular small adjustments to keep the supply and demand of electricity in balance and keep the system operating at the required frequency — a tight band around 50 hertz.
The Tesla big battery is registered to provide these "frequency control ancillary services" or FCAS.
According to AEMO, the speed, precision and agility of the battery is unprecedented in dealing with these regular, small frequency variations as well as major power disturbances.
Conventional coal-fired or gas-fuelled generators might take seconds; the battery takes milliseconds.
Not only are its responses technically superior, it has also lowered the cost of providing these services.
