That means that, on some days of the week, peak power will coincide

Butbutbut... The tides are not simultaneous. They vary from place to place
(Southampton has twice as many as most other places as well) This should be
enough to reduce the peaks/troughs.

True, but the variation from north to south in Britain is only a few hours
(can't recall the exact number). The more salient point is that not everywhere
on the coast is a suitable turbine site. You need spots where tidal currents
are very high.
