well with a typical power station being somewhere upwards of a Gw, and our
total energy needs as a country running at an estimated 300GW, I cant see
those making a huge difference to anything.

I can, hydro electric are easy to control and respond quickly.
Run them at the bare minimum and you can turn them up to smooth supply
during peaks.
Pretty much like the pumped hydro stations but not as big.
