Hydropower glossary

Project Overview

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 man-made 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 873 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 known as 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 8MW of energy.
