Same sort of issue really. You could have a tidal barrage across the

Severn).

Morecambe Bay IIRC.

"H R Wallingfords research consisted of both on site measurement and
modelling and identified that the maximum outputs for power production
outputs in the Bay could be as much as 2-3GW."

The biggest Severn scheme, if Wikipedia and the Beeb can be believed, is
8Gw. For 8 hours per day, and not at neaps.

peak outputs are useless. Its lowest output and peak to mean ratio that
determines usefulness.

read it.

You are preaching to the choir Which part of "For 8 hours per day,
and not at neaps." did you not understand?

I'm quite aware that Morecambe Bay plus the Severn might let us shut
down Sizewell B, and perhaps Hinkley Point - but nothing else. And only
at the cost of some pretty significant wildlife sites.
