RIP Trevor Baylis

As long as you don't have windmills and solar panels on the grid, rotating turbines have enough energy stored in the spinning masses to do a marvellous job of stabilising the mains over periods up to a minute.

Thats well long enoiugh to open te throttles on a water turbine or a steamp turbine with decent sized boilers.

Back in the days of 'all coal' the spinning mass was the first line of stability and a boiler full of steam was the second.

That is around the time I bought a small JVC portable telly ,had a screen of 5? . It took 8 D cell batteries and despite only being a BW set it ate them. I came across and purchased my first set of Nicads and charger which were branded Berec which I thought may have been unknown and possibly slightly risky unknown brand. Turns out it actually stood for the British Ever Ready Company to differentiate it from the US one from which they had split around the time of WW1 but they rarely used the Berec name in the U.K. market. Can?t really say now how well the batteries lasted as most got used in torches which I mislaid rather than wore out. The Charger was still going 5 years ago and may still be but I haven?t been back to the persons I gave it to for a while.
