Project Overview

Hydropower glossary

Intake or Diversion: The taking of water from the river into a canal, or other conduit.  At Electron, this is also called the headworks.

Flume: A deep narrow channel with a stream running through it; a water chute.  The flume at Electron is 10.1 miles long.

Reservoir: A manmade lake or pond for the storage, regulation, and controlled release of water.  The Electron Reservoir is commonly known as the Forebay.

Penstock: A closed conduit or pipe used for transporting water to the powerhouse.  Each of the four penstocks at Electron is 2200 feet long.

Head: The vertical change in elevation between the reservoir water level and the level at which the water exits the powerhouse. Electron utilizes 872 feet of head.

Powerhouse: The structure housing the generators and turbines.

Generator: The machine driven by turbines that generate electricity. There are four 3500 KW General Electric generators in Electron's powerhouse.

Turbine: A wheel that converts the energy of moving water into mechanical energy. Electron's turbines are Pelton water wheels and are eight feet in diameter.

Megawatt (MW): The equivalent to one million watts. A megawatt is the unit of power used to measure the output of a power station. Electron currently produces approximately 22MW of energy.
