Melbourne's Bay Bridge - Potentially the best. List of global tidal projects.https://en.m.wikipedia.org/wiki/List_of_tidal_power_stations
The CEO of MeyGen at Pentland Firth, Scotland is Mr Tim Cornelius. Tim is from South Australia and works with Atlantis tidal on the 400 MW tidal instal with Atlantis, originally an Australian Company.
My guess is that a tidal stream generation project using the piers of MBBridge as anchor points for multiple Atlantis 1.5 MW generators, or even purpose designed housings for generators with shaft drives could make it a world beating project.
If each Hydro generator made 100 MW annually then:
60 sets of piers (two wide); each with two turbines fitted per pier. Generating 200mwh's each: that's 800 mwh's per set of 4 multiplied by 60 giving 48,000 mwh's of electricity per year. Or, 48 gigawh's.
So, 480 generators by way of comparison against the total install at Pentland Firth of 400 generators.
MBBridge would be generating more electricity than any other of its type.http://mobile.abc.net.au/news/2017-03-20/hazelwood-closure-leaves-major-energy-black-hole-prices-to-rise/8367826?pfmredir=sm
