Lesson from Spain and Portugal - more large turbines and inertia needed in the UK?

Spain, and to a lesser extent Portugal, experienced widespread and massive power outages on 28th April.

Airports closed, no traffic lights, trains marooned, no credit card facilities ... and practically no cash as ATMs stopped working. The impact on the population and businesses was painful and severe.

Investigations continue into the cause of the system failure, as reported on Techexplore and the Baker Institute:

So how is this relevant to the North Wales Tidal Lagoon?

In common with other tidal range projects, the North Wales Tidal Lagoon offers reliable and predictable energy generated using large turbines that will help provide system inertia and both frequency and voltage control. Should our lagoon be built, alongside others on the West coast, tidal range would help prevent such an outage occurring in the UK.

As the UK Government studies the impact of Iberia's power outage and the lessons that need to be learnt for our own Grid, it is clear that tidal range has, at the cost of much pain and suffering in Spain and Portugal, gained yet another good reason for support.
