Some years ago I was told that BW was considering putting a turbine in at Grindley Brook but then the idea seemed to disappear. Given the flow down the Llangollen runs at around 11 million gallons per day and the water needed for boats is just 3 million there is a lot of energy going to waste - or going to endanger boaters given the cross flows at the bottom of many of the locks. A few years age I watched a boat at Baddiley top (a lock that currently has the Amoco below smashed up with one chunk by a mooring bollard draped in Defra Rash while sticking out 4' into the canal at right angles). Back then when BW did some maintenance and Defra rash weren't invented the boat crew had all the lock paddles up top and bottom for a number of minutes but this had no visible effect on the water flow going downstream via the weir. Energy for free going to waste.
