Baseload plant

An energy plant devoted to the production of baseload supply. Baseload plants typically run at all times through the year (24/7) except in the case of repairs or scheduled maintenance.


The minimum amount of power that a utility must make available to its customers.


Cold water pipe, the pipe used to transport deep ocean water to the OTEC condenser.

Draught (Draft)

The depth of a ship’s keel below the water surface.

Euphotic zone

The upper layer of the ocean in which there is sufficient light for photosynthesis.


The costs generated by the production of electricity that are not included in the price charged to consumers. These costs manifest themselves through changes in the environment and other societal costs.

Gross power

The electrical power generated by the turbine­generator.

Net power

The electrical power available for export from the OTEC plant. The difference between gross power and in­plant power consumption needed to run all...
