Randy Hobby Ti*qun Energy, Inc Randy, The Alaska Department of Fish and Game i's in the final stages of planning for construction of a new hatchery near the existing Elmendorf Sport Fish Hatchery and is seeking opportunities to reduce long-term op;,.., ational costs., Tiqun Energy has illustrated the potential to support our needs through renewed operation of the KAPP cogeneration facility. ADF&G would be eager to enter Rk intoan agreement with Tiqun provided that ADF&D is not required to accept additional operational or regulatory risk and that meaningful monitary savings can be realized. ADF&G iffis currently enguaged in final facility planning and should begin detailed design work in May of 2008, During this design phase we will be finalizing the thermal demand and power use profiles for the facility. The following table presents the general estimated building and process water heating needs. Heat need Amount Comment Peak process water load, 11. 0 mmbtu /hr May be able to use condenser cooling water with includes 100 gpm truck fill final heating using district heat Peak building heat load 5.6 mmb tu hr Must use district heat Lightest process water Load 3.6 mmbtu hr May be able to use condenser cooling water with final heating using district heat Average yearly process water 7.0 mmbtu/hr May be able to use condenser cooling water with load final heating using district heat Average yearly heating load, 9.0 mmbtu/hr Must use district heat for building HVAC process plus building HVAC Previous Maximum Heat Load 150 mmbtu/hr Up to 9,000 gpm of 75°F water received from US Militry Power Plant on Elmendorf AFB Estimated Power Demand 500-600 kW/hr ■ 5/000/000 kW yr Note: It should be noted that this analysis does not consider the pumping energy needs to push the heatd water through heat exchangers. The cost of pumping must be considered in evaluating the economics of this heat source. While ADF&(i currently plans to install on site natural gas fired boilers to provide this heat we dare prepared LO accommodate the use oi other heat sources such as low temp (80° r ) condenser cooling water and higher temperature district heat. Maximum well water flow to the facility may be as high as 2,300 gpm but we do not anticipate heating more t F),, Until minimize Ti'*qun to evaluate and execute a 1 resource and creates the greatest Sincerely, �9 Jeff Milton ADF&G, Division of SportFish Hatchery Program Supervisor 333 Raspberry Road Anchorage, AK 99518 - I- 907267-2523 han 1,600 gpm t"roin (40° F64' further dtfesign work is complete ese are simply estimates and we will be working to this demand ns much ns possible.
