A battery can do more than save electricity for later. Terang's newly commissioned project in Victoria is a useful example of why the inverter and control system deserve attention alongside the battery cells.

For households, the technology is worth understanding without turning it into a promise about every home battery. Equipment can share a broad category while performing very different jobs.
FRV's commissioning announcement describes a 100 MW, 200 MWh battery project at Terang.
The announcement identifies Victorian Energy Innovation Fund support for grid-forming inverters. That is a specific part of the project's technical story, separate from the amount of energy stored.
The simple capacity-to-power ratio is two hours. It is useful for understanding scale, but it is not a guarantee that the project will always operate at full output for exactly that period.
An inverter connects the battery's electrical output to the alternating-current system. Its control strategy affects how it responds to the grid, not just how much energy passes through it.
Grid-forming technology can establish and regulate an electrical reference, supporting stable operation when appropriately designed and integrated. That differs from simply following an existing reference.

The ARENA grid-forming battery programme explains why these capabilities are being developed. A label alone does not specify every service, operating condition or performance requirement.
Moving energy from one hour to another is an energy-management function. Helping a power system respond to disturbances is a control and stability function. A project may be designed to provide both.
I would not describe a battery as replacing every function of a conventional power station. The required services depend on the wider system, and different equipment can provide different parts of the answer.
This also explains why comparing projects only by MWh misses useful information. The inverter, network connection, controls and contracted role all influence what a battery can contribute.
For home storage, ask what the system does when the grid fails, which circuits it supports and whether solar can continue operating in that particular backup arrangement.
Do not assume a grid-scale technology announcement changes the capability of equipment already installed at home. A system needs to be designed, configured and commissioned for its intended job.
If you want to support a larger load such as air conditioning, the output limit matters as well as stored energy. My recommendation is to define the useful service first, then assess the equipment that can deliver it.
