2. The Growing Trend in World Geothermal Installed Capacity
An increase of about 800 MW in a three year term ( ) has been achieved, following the rough standard linear trend of approximately 200/250 MW per year 2

3. Distribution of Geothermal power
Installed capacity sharing among the continents
a total of 12,000 MW in 24 countries 3

4. A clean and economically viable alternative
A 300 MW

site in the
Philippines
Geothermal Energy accounts for 1/5th of the
total electric power generation in the Philippines

5. 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)

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

10. Pebble Creek Viable Power Corridors
Besides geothermal,
about 150 MW hydro capacity is planned to be developed
in the Pebble Creek area.
Tecto generated
Power will be connected to the BC Hydro gird at
Pemberton
(red line).

11. Brief History of South Meager Creek (8km South of Pebble Creek)
On the left:
MC1 discharging 200 °C two phase
geothermal fluids.
The first Canadian geothermal pilot plant was successfully tested for 40 days in 1984 with the discharge from MC1.

19. Looking deep in the ground Cores from Meager Creek area
Study of core samples from deep core holes
From Meager Complex show the presence of both primary and secondary permeability associated with volcanic vents.
Intrusive rocks close to the vents are also highly fractured.

21. Flash Steam Geothermal Power Generation Technology
(most of the world’s geothermal power capacity)
The Pebble Creek Geothermal resource is high-grade,
to be exploited by Flash Steam technology.

22. Cost, Revenue, Payback
Flash Base Case – 8000 ft wells, 200°C, 500K lb/hr, Basin and Range drilling, Dual Flash plant
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.

26. 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.
