This Heres an inside look at one of the two turbine generator units at the Kalaeloa Partners 180 MW power generation facility. -395 Hydro electricity units use flowing water to spin a turbine connected to a generator. In a falling water system, water is accumulated in reservoirs created by dams, then released through conduits to apply pressure against the turbine blades to drive the generator. In a run-of-the-river system, the force of the river current applies the pressure to the turbine blades to produce electricity. In 2000, hydroelectric generation had the fourth largest share 7 percent of electricity production at 273 billion kWh.
