I don't see any need to bring back coal but we do need to ensure that there is sufficient short term supply to compensate for the lack of high inertia generators .
It must be possible to design a battery inverter system that mimics the response of a rotating plant in terms of output vs frequency and, given that most conventional plant can run at 110% of rated output for an hour or so, the battery capacity could be designed on the same basis, I.e. 10% of the local wind or solar generator.
