The difference between high tide and low tide is the greatest.

Explanation: Spring tides (at new and full moon) occur when the Sun and Moon are aligned, so their gravitational effects reinforce each other. That produces a larger tidal range (bigger head and stronger flows), giving more potential energy for turbines and thus higher electrical output.
