Jamaica lacks the potential for large-scale hydroelectricity generation. Only some 23.8 MW of power is presently installed with potential for about another 100 MW.
The type of hydropower installations can be classified in the following ways:-
-
By the effective head of water, low, medium or high heads.
-
By the capacity, the rated output.
-
By the type of turbine used.
-
By the location and type of dam or reservoir.
Hydropower schemes have high capital costs, and are sensitive to the high interest rate regimes in Jamaica in recent times, and therefore, prohibit private investment in hydropower ventures.
