Iberian Peninsula blackouts: comment

"Major blackouts are rare but have always happened. The last partial blackout in the UK happened in 2019 when lightning strikes caused a gas power plant and a wind farm to trip, leaving trains stuck and thousands of homes without power. The exact causes of this week's Iberian blackout remain unclear, but as in the UK in 2019, the key trigger looks to be two major generation outages occurring at a similar time, causing a large cascade of impacts. No power system is 100% reliable, and it is up to the grid operators and generators to engineer a system that minimises the chances of something like this occurring."
