3. Purpose
Convert waste fuel into emission free electrical power
Reduce Operating Costs
Reduce Trafinas environmental foot print
4. Trafina
Trafina is a junior oil and gas company based out of Calgary Alberta.
The company has interests in the Wetaskiwin/Bittern Lake, Carson Creek/Judy Creek, Retlaw, jenner, Kinsella and Ronalane areas in Alberta.
Also has interests in the Rangeview/Divide field in Saskatchewan
5. Ronalane
Ronalane consists of two fields, North and South Ronalane
Composed of 10 wells and one
battery at
06-16-13-12 W4M
6. North Ronalane
Has 5 wells which produce approximately 80Mcf/day of slightly sour gas at 51 PPM of H2S
4 Wells have 50 hp progressive cavity pumps and 1 well has a 75 hp pump
The max power consumption is 163 680 kwh.
The actual power consumption is 71 424 kwh/month
7. South Ronalane
Has 5 wells that is expected to produce 80 Mcf/day of gas
4 wells have 50 hp progressive cavity pumps and 1 well has a 15 hp pump
The max power consumption is 163 680 kwh/month
8. 06-16-13-12 W4M
The field has a common battery where the gas to power turbines will be installed
The power consumption at the battery is about
71 052 kwh/month
160Mcf/day of waste fuel is expected to be flared off at the battery
9. Genalta Power Inc
Genalta is an integrated renewable energy developer that captures waste heat and fuel and converts it into clean power within the oil and gas sector
Genalta uses their Fuel Conversion Module that burns waste gases that would normally be flared into the atmosphere to generate electricity
10. Genalatas Fuel Conversion Module
Consists of:
Turbine
Power Electronics
Enclosure
Auxiliary Components
Gas Boost Compressor
Heat Recovery Unit
11. FCM Specifications
12. Output Performance
13. Greenhouse Gas and Clean Air Credits
With and estimated value of $15/tonne the CO2 credits would have a potential annual value of $41,742. This revenue will be shared by the joint venture
14. Power Rate Options
Option 1
Establish a fixed power rate of $0.095 hWh indexed to inflation.
15. Power Rate Options
Equal to 10% less than the average monthly AESO Rate in each preceding month provided that Genalta receives no less than the Floor Rate ($65 MW/hr) and Trafina will pay no more than the Ceiling Rate ($150MW/hr)
If the Energy Rate falls below the Floor Rate Trafina will pay the Floor Rate but will accure a credit equal to the difference between the Floor Rate paid and the Energy Rate (the Floor Credit). The Floor Credit will be accured to the account of Trafina and will be applied against future payments to Genalta.
16. Analysis
Power Consumption
Power Production
The power consumtion for the South wells are 163,680kwh/month.
The power consumption for the North wells re 71,424kwh/month
The Battery Consumes 71,052 kwh/month
The total consumption at Ronalane is 306,156kwh/month
The 4 units from Genalta will produce 288,000kwh/month
This will produce apporximately 94% of the sites current power requirments
The four units will consume 128mcf/day of waste gas which will leave 32 mcf/day of waste fuel to be flared off.
17. Analysis
Location
The optimal location for these turbines should be relatively close to the treater and flare line
Having it close to the treater will allow for simple tie in for heat from power units and having it close to the flare line will assist in the waste gas tie-in to the turbines

Flare
Horizontal Separator
Proposed Location
18. Energy Rate and Cost
Option 2 is best used for short term projects
The average cost of electricity in 2008 was $0.118kwh, option two would reduce this cost to an average of $0.106kwh
19. Energy Rate and Cost
The four units would produce 288,000kwh/month
The total power consumption will be 306,156kwh/month
This would result in 17,156kwh/month of electricity being bought off the grid at an average price of $0.118kwh
The total cost per month would result in $32,552.41
This would result in an electricity savings of $42,888 per year.
20. Project Savings
The project cost is estimated at $880,000. Trafina will participate for 10% of this cost ($88,000)
The average electricity will cost $32,552 per month
The minimum electricity cost would be $20,745 per month
Greenhouse Gas Credits will amount to a profit of $4,174.20 per year
Electricity savings will account for approximately $42,888 per year ($3,574 per month)
21. Conclusion
Trafina Energy will agree to a 10 year term to install 4 FCM units at the North Ronalane Site (06-16-13-12)
The units will consume 128 MCF/day of waste gas which will generate 9600 kwh/day of electricity
This electricity output will account for approximately 94% of the sites power requirements
Electricity savings will account to $42,888 per year
22. Recommendations
Install 4 FCM units at the North Ronalane battery which will consume 128MCF/d, generating 9600kwh/d which accounts to approximately 94% of the sites current power requirements
Choose option 2 of the purchase power agreement
Install the units by this summer after South Ronalane has been tied into the North Ronalane battery
