Low grid inertia looks like the underlying culprit to me. A steady move away from large synchronised sets as a result of driving towards CO2 emission limits (ie little/ no coal fired and preference for renewables) coupled with about 2000MW of nuclear units (ie big low carbon generators) being on long term outage is pushing the grid to its limits. National Grids automatic protection seems to have worked well in stoppping the entire grid falling over - maybe there's some post event questions to ask about what the sequence of load shedding is (dropping domestic consumers seems far more preferable than dropping hospitals and national infrastructure).
