> in the frequency control auxiliary services (FCAS) market the provider with the fastest response can completely control the market, forcing other providers to transfer almost unlimited wealth in any desired direction

My understanding of the FCAS market is that it is quite shallow, and while there is indeed a first mover advantage that Hornsdale (Tesla battery in SA) has capitalised on, if all the other battery projects in Australia go ahead, they'll probably collapse the price.
