Geothermal power plants for Indonesia

100% of the electricity demand could be covered by

renewable resources in Indonesia

To use these enduring resources Indonesia needs high-

end technology, e.g. from Germany

Success!+

Role of geothermal power in the energy mix

Drivers for development of geothermal industry

Locally available Indonesia has about 40% of world wide knownresources, which are widely distributed, generally highly productive andhigh enthalpy resources

Need to quit from reliance on oil and other fossil fuels Base load capacity of geothermal power generation is over 90%

Independence of cost increase, deliverability and waste management offossil fuels

Environmentally friendly and renewable energy: zero emission possible

CO trading and clean development mechanism (CDM)

In Indonesia geothermal energy shall have a significant role in theenergy mix!

Kalina technology: Highest efficiency for geothermal power

Brief summary: Kalina Technology

up to 50% higher plant efficiency

up to 30% lower production costs

reduced emissions (closed circuit) less brine/steam consumption inprocess

more energy recuperation comparedto ORC

lower life-cycle cost of electricity per

kilowatt-hour

Highest efficiency for low & medium enthalpy resources, brine andrecovery heat processes; increases efficiency of any conventionalgeothermal power plant

Combined cycle geothermal power plant
