According to a couple of sites, this could possibly be the type of gas generator being considered for SA.

Key features are an integrated battery that will provide instantaneous power and also keep the turbine spinning without using any fuel, so that it can be on line almost instantaneously. The turbines can run on a variety of fuels, so presumably an onsite backup reserve of LPG could be available in case somebody decides to play silly buggers with mains gas availability - or if mains gas is not available at a chosen site (if this class of system is used, there would need to be ~5 of them placed across the state).
If they can't get something in place quickly, apparently the plan is to bring in temporary generators (possibly even diesel, as in Tasmania) to help get through until next summer, until some new gas capability comes on line - seems that everything is on the table now that the decision has been taken to reduce reliance on the national market players.
EDIT: pity extra generators are not around already - AEMO is forecasting that power prices will spike to $14,000/Mwh tomorrow afternoon (Sunday) - PV will be doing well, but wind is in the doldrums and it will be a hot day.
