Introduction
• Hans Behm – Founder & Patent Applicant– Designer / Builder
• Eric Neary, P.Eng.– Alternative Energy Technology Specialist

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.

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

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

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

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

Benefits
• Only bears a portion of the project cost
• Increased power generation & revenue
• Public support for green power with no GHG emissions
