Possible evolution of a small double-flash geothermal unit (5 MW)
CFG SERVICES (CFG) is an engineering company, subsidiary of BRGM, conducting high 
and medium enthalpy geothermal projects from the exploration phase to the field 
development. Its main activities are project management, borehole engineering, 
geological and geochemical monitoring and survey, development and implementation of 
test programs, corrosion and incrustation studies, technico-economic feasibility 
studies. CFG has en 8-years-long experience in geothermal development in Guadeloupe 
as owner and operator of the existing 5 MWe power plant and an extension of 11 MW 
commissioned by the end of 2004. CFG also developed a large know-how in the 
maintenance and operation of low enthalpy geothermal exploitations in the Paris 
Basin for district heating. CFG has been participating to previous THERMIE and 5th 
FP projects.

The purpose of the presentation is to provide preliminary analysis of the possible 
evolution of the Bouillante 5 MW double-flash steam turbine unit :

There are mainly 4 options to be analysed :

1) Revamping of the unit according to the existing status : double-flash steam 

2) Idem 1 + small binary cycle on available separated water (after HP separator)

3) Single flash turbine (HP only) and larger binary cycle

4) Actual double flash turbine totally replaced by a binary cycle.

The paper will give the results of the preliminary analysis.

These results are still to be confirmed by a detailed technico-economic study, 
taking into account technical, financial, economical but also environmental 
considerations, the unit being installed in the city of Bouillante (Guadeloupe).
