Geothermal Power Plants,
Worldwide Status - 1986
by
RONALD DIPIPPO*
Abstract
This paper presents a survey of
geothermal power plants around the
world as of 1986. The data are given
mainly in tables. The current state of
affairs is relatively unchanged from
that reported by DiPippo at the 1985
lnternational Symposium on Geothermal Energy.“’ The slowdown in
expansion predicted by DiPippo at
the 1985 IIEIEPRl Geothermal Conference and Workshop‘” is already
becoming evident. In fact, the
installed capacity worldwide has remained essentially unchanged from
1985 to 1986: projected capacity at
the end of 1985 - 4763.981 MW;‘”
projected capacity at the end of 1986
- 4733.446 MW. The slight drop is
due t o latecompletion of some plants
scheduled for 1985. This paper contains a country-by-country tabulation
plus a summary of plants by type of
energy conversion system.
Summary By Country
Table 1 shows the growth in installed geothermal capacity dating
from 1979. The 17% annual growth
rate that applied until 1984-85 will
not continue. DiPippo predicted a
growth rate of 6.1% from 1986 to
1990.‘2’The effect of the drastically
depressed price of oil on the expansion of geothermal plants will be
severe if oil prices remain low, i.e., in
t h e $10-15/barrel range, for a prolonged period. Sustained geothermal
growth requires countries such as the
United States, the Philippines, Mexico, and Indonesia t o continue their
steady building programs. A relaxation of the target dates for completion
of new plants or delays caused by the
inability to arrange financing for new
plants ordelayscaused by the inability
to arrange financing for new projects
will result i n a postponement of construction or a stretching out of the
schedule for completion of plants.
The outcome will be a very low effective annual growth rate. Indeed the
rate may even become negative; some
geothermal plants (in the United
States, Italy and New Zealand) are
more than 25 years old and might
reasonably be expected to be retired
from service in the near future.
Table 2 lists the countries with
active geothermal plants and gives the
number of operating power units and
the installed capacity for plants of
four types of energy conversion system: dry steam, single-flash, doubleflash, and binary.
In all, there are 190 operating
units and 4733.446 MW expected by
the end of 1986, The United States
operates 57 units (or 30%of the total)
withacombined capacity of2006 MW
(or 42% of the total). It is interesting
to note that the power complex at
The Geysers accounts for about 38%
of the worldwide capacity, and that
California alone has about 4 I % of the
world’s geothermal capacity. The
United States is also the only nation
to have in operation plants of all four
types.
The average size of power plants
varies widely: 33 MW for dry steam
units, 22 M W for single-flash units,
35 MW for double-flash units, and
2.5 MW for binary plants. If the Heber Binary Demonstration Plant (45
M W) is excluded from the averaging
process, then binary units would
average only I M W. There has been a

recent proliferation of small, modular, factory-assembled binary units,
as for example at East Mesa (ORMESA Project), Mammoth Hot
Springs (Mammoth-Pacific and
Chance Ranch), Wabuska Hot
Springs, Steamboat Springs, Hammersly C a n y o n , Wendel H o t
Springs (Wineagle), and Cove
Fort/Sulphurdale, all in the United
States.
Tables 3-21 summarize the
status of plants in all countries with
operating geothermal plants.
Future Prospects
Table 22 lists countries that
have the potential to become producers of geothermally-generated
electricity in the near- to mid-term.
The most certain of these are Costa
Rica and Guatemala where the first
plants should be under construction
withina year. I t is likely that at least
one additional unit will follow in
each country.
Some of the other countries are
reported t o have sizable geothermal
power potential (e.g., Djibouti - 300
M W), but plans for construction of
plants are indefinite.
