Tidal energy generators
Unique to Bristol is the high tidal range (Avon New Cut) adjacent to a large body of water at high-tide level (Floating Harbour). There is a lot of potential energy arising from this water level difference. Further, there is tidal flow in and out of the Avon. To get a sense of the power, watch the sluices open at the Underfall Yard at low tide!
The idea is to use this to generate renewable energy for Bristol. For example, a siphon construction of pipes can allow water to flow without rebuilding the quayside, with a generator in the water flow. Or a water wheel that works with the flow of the river. Or even water based heat pumps to warm harbourside buildings.
There could be a range of generators aligned along the New Cut, each to demonstrate one form or other of power generation or construction.
Why the contribution is important
City-centre energy generation from a renewable source.

A better idea would be damming the Avon near Avonmouth, the head & water quantity would be significant & could also act as a flood defence for Bristol :-)
This would also make a large amount of sheltered water available for leisure.
Clearly the council have no money available to do this but an energy company with power rights for 30 years perhaps?

The power provided would also be predicable as we know tide tables for next millenium, more than can be said of wind.

Here's a radical thought, to make the usage of the electricity a work of art too. The amount of energy generated will fluctuate, from more to less according to tide levels. As more energy is available, more lights switch on, as less is available fewer lights are on. Perhaps a different colour shade, to show if the lights are lit by tide or grid. The lights might be for street lighting, but could also be used to uplight cranes (they are a city feature, always in the dark)...The cranes are only lit and visible at moments of energy generation, and only as much as is generated...
