"This is because the two reservoirs are linked by one of Britains biggest

generated by letting it flow back down at times of peak demand"

Went around in 2003 - very impressive. Would be even more impressive
in solar/wind could be used to refill the top reservoir.

What makes you think it isn't ATM? Electricity, once generated,
becomes anonymous and untraceable, so it's reasonable to assume that a
proportion of the night-time wind-generated electricity goes to
refilling the top reservoir, when there's wind, that is. Of course,
that reservoir is filled at night when demand is low and there's
surplus on the grid, so no solar available for what you suggest.


Solar could do some refilling during the day. Just cover most of
Wales with panels. Out of curiosity, anyone calculate how many panels
would be needed to lift one ton(ne) in say 6hrs of average light?
