Britain struck by unusual power activity hours before blackouts in Spain and Portugal
Britain’s grid operator confirms it is investigating unexplained changes in electricity frequency seen on Sunday
According to a friend in the industry, it's basically a non issue. Things like this are not uncommon, and wouldn't have even made the news, without what happened in Spain.
The national grid was less designed and more accreted. There are a lot of parts that are sub-optimal, but we are stuck with them due to the cost of replacement. They are therefore very hot on containing, and learning from any failure that happens.
The frequency changes to adjust for the load, this is completely normal. When you lose a large power source the whole grid runs a bit slower to compensate for it. The question is why was Britain affected, I thought it's not synchronized to the european grid.
