Re: Really?
Some UPSes are for power filtering and covering until the generator starts up. That would leave extra capacity for reducing grid load.
The problem is when the UPS is drained down to the minimum reserves but the grid is still overloaded. Turning the mains power back on would not only resume normal load, but add the load of recharging the UPS batteries. The other option would be starting the generator. I don't know about the generators in Ireland, but the ones in Silicon Valley run about as clean as a tire fire.
