Engineering Services for Geothermal Development
Featuresu Trend of renewable energy use
A number of developing countries are facing energy issues including regional disparities in electrification
rates and strain arising from a growing demand for power. Since this is one of the factors inhibiting
poverty alleviation and economic growth, the development and stable supply of low-cost and clean
energy is in demand for the people. Geothermal energy features superior supply stability and a low
emission of global warming substances. As a purely domestically produced renewable energy,
geothermal energy is drawing a lot of attention from the perspective of energy security and mitigation ofglobal warming.
u Abundant track records in electric power engineering services
Nippon Koei have been providing consulting services in the field of power development for more than 50
years in response to local issues of individual nations around the world, e.g. the formulation of optimum
power development plans, the design of facilities, such as power plants, power transmission anddistribution networks, as well as substations.
u Proposals utilizing advantages as total consulting service provider
As a total consulting service provider with expertise in a diverse range of fields, such as electric power,
civil engineering, agriculture, city planning, etc., we are not only able to propose power development,
but we also offer solutions on regional development with the direct use of geothermal resources.
u Active Efforts for the Development of Geothermal Energy in Latin America and East Africa
We are actively engaged in consulting services for geothermal energy development with thegovernments in Latin America (Bolivia, Peru etc.) and East Africa (Ethiopia, Djibouti etc.) where they
have abundant geothermal resources.
Basic Concept or Summaryu Geothermal studies
We study geothermal manifestations such as fumarolic gas and hot springs on the surface of the groundand combine them with findings from geophysical and geochemical surveys in order to appropriately
select candidate sites for geothermal development.
u Geothermal reservoir assessment and simulation
We support the formulation of geothermal power plant construction plans for geothermal resources
using geothermal well data from three-dimensional geothermal fluid dynamics and heat transport model
analysis to evaluate the geothermal resources which can be developed.
u Geothermal power plant projects Survey, design, implementation and implementation management
Nippon Koei provides comprehensive services in the overall project cycle from surveys for geothermal
power plant projects in various locations in the world to the design, implementation and supervision ofthose projects.

Effects or Remarks
Geothermal power helps to reduce fossil fuel utilization, as well as carbon dioxide emissions. This not
only improves the environment, but we can also expect benefits by registering the project as a CDM
project.
A number of remote areas in archipelagic countries as well as mountainous countries, where grid
systems have not been well developed, have only diesel power to meet the regional electricity demand.
Power generation costs could be reduced by replacing diesel with geothermal.
Conversion into geothermal energy, which is a purely domestically produced energy, not only becomes
possible for reducing the amount of fossil fuels imported, but other benefits can also be expected, e.g.
exporting fossil fuels produced within the country as a means to acquire foreign currency by saving
domestic consumption.
