In reply to pjar.

I apologise for lateness of reply. Spain has about 60% renewables whereas ours is about 42%. I believe on the day of the blackout in Spain, it was in the high 60’s% renewables. Many of our substations are indeed too old and prone to breakdown. The fluctuating nature of renewables supply does cause problems matching generation to load. This fluctuation causes frequency changes leading to power blackouts. As our conventional power generation gives way to renewables, we lose inertia power leaving us wide open to blackouts like in Spain. Notice how Ed Miliband never mentions inertia power in his mad drive for renewables.
