WEST uses wave motion to operate pumps which generate pressurized seawater fed into a hose extending from the WEST units located far offshore where the waves are bigger and more consistent, to the onshore generating facility, where the pressurized seawater is sent into a Pelton motor connected to electrical generators.

Five main components comprise WEST: the buoy, pump, variable sea anchors and connecting hose offshore; and the onshore Pelton motor and generator. Pictures of these full-size components may be seen below:
