An Economic Comparison Between Conventional and Modular Geothermal Development Models

Abstract

The concern of the energy for t o the steaa p r i c e , stean pr ice should enable the geothernal producer t o recover the pre-production investaent, operating expenses, taxes and al so t o achieve an a t t r a c t i v e r a t e of return, The steaa p r i c e should also enable the user t o the generating cost of the geotheraal power plant, This paper describes the conparison study of the econonics o f two hypothetical geothernal nodels: conventional and nodular, The conventional is designed t o deliver geothernal s t e a r i n t o two centrally located power plants, while the modular i s designed t o deliver the steaa i n t o six portable power plants located separate 1 . The nodular requires a higher pre-production investnent, b u t due t o a shorter pre-production period, the is nore a t t r a c t i v e econoaically,
