Abstract
An economical comparison is made between geothermal power at Sulphur Springs, Soufriere, Saint Lucia and diesel generate power from a new diesel power station at Cul de Sac to the south of Castries. The comparison is over a 20 year period. The new diesel power station is scheduled for commission during the second half of 1990. The capital costs for the Cul de Sac Station are based on actual contract sums for Stage 1 of the development pogramme, comprising of 2 x 6.3 MW generating units. Development costs for a 2 x 5.6 MW dry steam geothermal power plant are based on actual well costs and estimated costs for the steam gathering system and power plant. The geothermal reservoir is assumed to be vapor dominated. Levelized costings will be adopted for comparing the total generating costs in cents per kilowatt hour associated with the two generating plants.
