► The economics of adding new turbines to a row spanning the width of a channel are better than the economics of adding new rows of turbines to a farm. ► Adding rows to a tidal turbine farm reduces the power produced per turbine, even though total power production may increase. ► Realizing the maximum power available in a small tidal channel may be possible with existing turbines, if they almost fill the channel’s width. ► Realizing the Giga Watt potential of large tidal straits will be difficult unless much of the strait’s width can be filled with turbines.
