Modular precast pumped storage hydro system for power generation

A power generation system, comprising:

• an impoundment structure at least partially defined by a plurality of precast segments and at least partially defined by a base, the impoundment structure being configured to store a volume of fluid, at least a subset of the precast segments interconnected via complementary coupling elements, the impoundment structure elevated with respect to a fluid supply;
• a flow path providing fluid communication between the impoundment structure and the fluid supply;
• a power generation module configured to pump fluid from the fluid supply and to produce a flow of the pumped fluid into the impoundment structure via the flow path;
• at least one energy dissipation element disposed within the impoundment structure at a position laterally offset from a perimeter of the base, the at least one energy dissipation element being configured to redirect the flow of the pumped fluid entering the impoundment structure;
• and
• a power conversion module configured to convert kinetic energy of fluid released from the impoundment structure and travelling through the flow path into electric energy.
