November, 2009Canadian PowerPlus Corporation2 Introduction Hans Behm –Founder & Patent Applicant –Designer / Builder Eric Neary, P.Eng. –Alternative Energy Technology Specialist

November, 2009Canadian PowerPlus Corporation3 Concept Variable Tailrace Technology –Patent Application (US60/815,850 filed on June 23, 2006) –Allows the elevation of the downstream water body to be adjusted For low output operation, level can be raised to eliminate cavitation in turbines. For high output operation, level can be lowered increasing effective head across turbine. Current Practice is to set the tailrace level as low as possible, but high enough to prevent cavitation during the low output operation.

5
November, 2009Canadian PowerPlus Corporation5 Variable Tailrace – Low Position
6
November, 2009Canadian PowerPlus Corporation6 Variable Tailrace – High Position
7
November, 2009Canadian PowerPlus Corporation7 Benefit Example – Seven Mile Dam –Max Output approx. 600 MW –Total Head approx. 62 to 66 m. depending on output (avg = 64 m). If variable tailrace installed, and head maintained at 66 m, incremental output at Max capacity = (66-62)/62*600MW = 6.45% * 600 MW = 38.7 MW
8
November, 2009Canadian PowerPlus Corporation8 Benefit At max output, gain = 38.7 MW At min output, gain = 0 MW Estimate capacity factor of dam at 50%, and linear relationship between output gain and capacity Realized Benefit = 0.5 * 38.7 MW * 8760 hrs/yr = approx 170 GWHrs/yr. (with no GHG emissions!) If electricity @ $46/MWhr, Increase Revenue = 7.8 Million CAD/yr
9
November, 2009Canadian PowerPlus Corporation9 Risks Construction Costs –Historical construction costs available for various dam sites Environmental / Permitting –No anticipated difference than excavation of tailrace Reliability –Design of variable tailrace would include Failsafe Design Redundancy of Operating Mechanism Complete HAZOP & RMA study during engineering phase
10
November, 2009Canadian PowerPlus Corporation10 Proposal CCPC looking for initial project Partner Partner to supply – –Site –Financing for a portion of the project –Expertise & guidance to support CCPC’s engineering design & execution plan
11
November, 2009Canadian PowerPlus Corporation11 Benefits Only bears a portion of the project cost Increased power generation & revenue Public support for green power with no GHG emissions
