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 geothermalpower 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.

Project 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 hasan 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 feasibilityfor 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 MThe payback period will be less than 6 years.
