"But many of the companies tasked with supplying the “safety net services” – such as batteries and diesel farms, which are banks of small-scale generators – have warned that National Grid is not doing enough to safeguard the system against blackouts."

In Germany, these are now being called "grid stability units". In other words, reliable fossil-fueled generators running to keep the grid frequency stable to avoid these kinds of outages recently seen in the UK.

London — German power grid operator Amprion has reopened tenders for two 300 MW of grid stability units after the tenders were suspended in the first quarter, a spokesman told S&P Global Platts Tuesday.

Last summer, grid operators Amprion, TenneT and TransnetBW called for bids for 1.2 GW of highly flexible generation units to be built in South Germany to help stabilize the grid from October 2022 amid the final phase of the nuclear exit.

Truth is, any power generator can trip off-line for any number of reasons. The 1965 Northeast Blackout happened because a transmission line from a hydro station at Niagara Falls tripped off, resulting in a cascade failure throughout the US Northeast, as well as parts of Canada. This doesn't mean that hydropower is no good. What it means is that enough redundancies need to be in place to handle a shutdown of a large generator with minimal impact on the grid.

The industry has a term called "spinning reserve". This is the amount of power that is already "spinning", that is already producing power at low levels, and can be quickly ramped up in case of a large power plant shutdown. My suspicion is the UK didn't have enough spinning reserve on-hand to deal with the loss of the large windfarm and the gas plant.
