Which outcome results when ice entirely occludes a hydroelectric turbine intake?

A)Cavitation erodes turbine blades faster
B)Generator overloading trips the breaker
C)Net power generation steeply decreases
D)Increased biological load downstream occurs

💡 Explanation

Hydroelectric power reduction occurs during ice occlusion because reduced water flow significantly lowers momentum transfer, thereby lowering overall power generation rather than generator faults, since the flow would diminish first, and cavitation and biological load are not increased.
