The Growing Trend in World
Geothermal Installed Capacity
An increase of about 800 MW in a three year term
(2005-2007) has been achieved, following the rough
standard linear trend of approximately
200/250 MW per year

Geothermal Power Development Costs
A useful rough estimate for a flashed steam power
plant system is about $2,000 to 3,000 per kW for a
larger (55+ MW) system,
These costs are roughly split between the power plant
itself (50 to 60%) and the resource infrastructure (well,
piping, water treatment, etc.) (40 to 50%).
For Pebble Creek the costs for the first 110 MW initial
development is estimated at about $2,500/KW
(including power plant and steam-field development)

Geothermal is a viable renewable,
ranking 4th after hydro, biomass and wind,
and significantly higher than solar in terms of
sustainability.

The Capital Cost for the first 200 MW geothermal
power generation at Pebble Creek is estimated at
500 million Dollars ($4000/kW installed, EIA, 2012).
At 9 cents/kWh the invested capital will be
paid back in less than 6 years.

Conclusion:
Geothermal power technology is mature, clean, and offers
the best solution for word increasing demand for electricity.
B.C. has at least 3000 to 5000 MW geothermal power potential
Meager Creek Complex is the most advanced Geothermal
prospect in BC with estimated 1000 MW Potential.
Tecto’s Pebble Creek (North Meager Reservoir) prospect has
an estimated developable power potential of above 500 MW.
The chemistry of the Hot springs and temperature data from
deep slim holes have proven the presence of a high-grade
geothermal resource associated with the Pebble Creek Hot
springs.
The cost of two Production-size confirmatory holes and feasibility
for the first 200 MW Development in the Pebble Creek Tecto
Property is estimated at 15 M.
The cost of 200 MW power development is estimated at 600 M
The payback period will be less than 6 years.
