Determining geothermal capacity is one of uncertainty in the beginning of a <br />
<br />
geothermal project. Until recently there is no certain procedure to determine <br />
<br />
optimum capacity to be generated in a geothermal power project. Thus the actual <br />
<br />
power capacity generated in geothermal field can be different with its potential <br />
<br />
estimation. This research studies about determining the most feasible option from <br />
<br />
several possible options with varied generating capacity, development phases and <br />
<br />
production period that will be analyzed. <br />
<br />
The technical modeling using lumped parameter with p/Z falling method will be <br />
<br />
used to calculate maximum potential of the field, estimate production decline of <br />
<br />
the field and make-up wells requirement to maintain a certain generating capacity <br />
<br />
for a certain production period. The financial model would be done to calculate <br />
<br />
cost, financial indicators as IRR (Internal Rate of Return) and NPV (Net Profit <br />
<br />
Value). The sensitivity also is done to understand the influence of electricity price, <br />
<br />
amount of investment cost and interest rate of the project to its financial <br />
<br />
indicators. <br />
<br />
Calculation using the model showed that there is no feasible option with positive <br />
<br />
NPV for electricity price USD 8 cent/kWh. Further simulation with minimal IRR <br />
<br />
12% showed that the required price to achieve the target is USD 8.79 to 19.63 <br />
<br />
cent/kWh. Simulation with varied investment cost showed units with bigger <br />
<br />
capacities (110 MW) will be feasible with investment cost 70 to 90% from <br />
<br />
previous estimated cost. Reducing the interest rate to 5 – 6% from previous 7% <br />
<br />
could also develop more feasible options. <br />
<br />
As suggestion, the government needs to be involved in reducing the total <br />
<br />
investment cost and interest rate for geothermal project development by activating <br />
<br />
their fund and adding more financial incentive in term of subsidy or reduction in <br />
<br />
interest rate. |
