ERDC/CERL TR-05-6Abstract: This study evaluated onsite and regional options for providingheat and power to Fort Wainwright, Eielson Air Force Base, Fort Greely,and the Ground-Based Midcourse Defense installation adjacent to FortGreely, collectively known as the Greater Fairbanks Military Complex(GFMC). The alternatives evaluated include site-specific alternatives(continued operation of existing plant and new plant) and regionalalternatives to provide power or both heat and power. The report providesbackground information on the energy supply situation in Interior Alaska,the availability of fuels, and the existing energy infrastructure and reviewsthe suitability of possible technologies for long-term heat and powersolutions for the GFMC installations. The report also develops evaluationcriteria for fuels and alternative heat and power solutions. Life-cycle costsare developed for each alternative and are used in the evaluation alongwith other criteria such as security, impact on Alaska infrastructure, andair and water quality. Results of the analysis are presented to allow theDepartment of Defense to make an informed decision about heat andpower solutions for the installations.DISCLAIMER: The contents of this report are not to be used for advertising, publication, or promotional purposes.Citation of trade names does not constitute an official endorsement or approval of the use of such commercial products.All product names and trademarks cited are the property of their respective owners.

ERDC/CERL TR-05-6Executive SummaryIn May 2003, the Assistant Chief of Staff for Installation Management(ACSIM) requested that the U.S. Army Engineer Research and Development Center (ERDC), Construction Engineering Research Laboratory(CERL) conduct a Joint Long-Range Energy Study for Fort Wainwright(FWA), Fort Greely (FGA), the Ground-Based Midcourse Defense (GMD)installation adjacent to FGA, and Eielson Air Force Base (EAFB), collectively referred to as the Greater Fairbanks Military Complex (GFMC).ERDC awarded a contract to CH2M HILL in August 2003 to perform thetechnical study.The goal of this joint study was to assess the options for long-range regional heat and power in the GFMC area and provide recommendedcourses of action to achieve environmentally responsible, reliable, andeconomically viable heat and electric power based on a 25-year period.This study provides the Services (U.S. Army and U.S. Air Force) and theMissile Defense Agency (MDA) with recommendations on regional andinstallation-specific approaches to the provision of heat and power supplyfor the GFMC installations.The tasks for achieving the objectives of the study included (1) the evaluation of fuel options and regional and installation-specific alternatives forheat and power supply, and (2) a review of possible power-generatingtechnologies, including renewable resources. The evaluation was done independently of specific ownership considerations. The following alternatives for providing heat and electric power to the GFMC were evaluated: Regional Electric Power Plant. This alternative involves building aregional electric power plant to meet the mission-required electricityneeds of the installations over and above the electricity generation atthe existing FWA and EAFB Central Heat and Power Plants (CHPPs),which is produced as a by-product of heat production. The plant couldbe either coal- or oil-fired.Regional Heat and Electric Power Plant. This alternative involves building a regional CHPP to meet the combined heating demands of FWA and EAFB and the mission-required electricity needs ofall of the installations. The plant would most likely be located on EAFBto avoid the Fairbanks carbon monoxide (CO) management/nonattainment area (NAA). This solution would require the construction ofiii

ERDC/CERL TR-05-6 a long-distance heat transmission system to FWA and to interconnectto the existing EAFB system. Similar to the regional electric powerplant, a regional CHPP could be either coal- or oil-fired.Repair. This alternative involves building continuing operation of theexisting CHPPs, accomplishing appropriate repairs, and buying additional power needs from Golden Valley Electric Association (GVEA). Inthis alternative, steam is produced to meet heating load, and additionalsteam is generated specifically to produce electricity, but only to thelimit of the existing CHPP design capacity.Repair and Upgrade. This alternative is similar to the Repair alternative except that additional new electrical generation capacity is added to the CHPPs to meet future electricity demands. This alternativeminimizes or eliminates electricity purchases from GVEA even as demand at the military installations increases.Repair, Using Electricity Produced by “Following the HeatCurve.” This alternative is similar to the Repair alternative except thatelectricity generation would be based on heat loads only. Unlike theRepair and Repair and Upgrade alternatives, no steam would be produced solely for electric power generation beyond what is needed tomeet heating loads.Upgrade Coal-Fired Boilers with New Circulating FluidizedBed Boilers (CFBs). EAFB anticipates replacing two current boilerswith two new boilers. This alternative was evaluated for EAFB only;FWA does not have similar plans.New Coal-Fired CHPP. This alternative involves building a newstandalone CHPP to meet the projected installation heat and electricityneeds.New Oil- or Gas-Fired CHPP. This alternative involves building anew standalone CHPP to meet the projected installation heat and electricity needs.Based on the evaluations, construction of new installation-specific coalfired CHPPs was the highest ranked and lowest life-cycle cost alternativefor both FWA and EAFB. This alternative has estimated capital construction costs of 201 million at FWA and 188 million at EAFB. All four regional alternatives have higher life-cycle costs than the installationspecific alternative. The regional option with the lowest capital cost is anoil- or natural gas–fired combustion turbine (CT) and heat recovery steamgenerator (HRSG) electrical power plant. Under this option, the existingFWA and EAFB plants would continue to be the source of heat and cogenerated electricity.iv

ERDC/CERL TR-05-6Sensitivity of the evaluation results was tested by weighting the variouscriteria and individual scores. The major criteria in the evaluation weresecurity (40 percent) and life-cycle costs (30 percent). Significant changesin the criteria weighting were required to significantly change the results.Without significant changes to the weighting, changes in individual scoresfor a particular criterion have minimal effect.The report concludes and recommends: Coal is the most secure fuel available in Interior Alaska.Regional solutions are more expensive and less secure than installation-specific solutions.Over the study period (2004 to 2028) with new plants coming online in2012, new coal-fired CHPPs at FWA and EAFB are the highest rankedsolutions.Because of its location, FGA has no economically justified regional solution. Electricity should be purchased directly from GVEA rather thangenerated at FWA and transmitted over the GVEA system. After including losses and GVEA transmission charges, it is less expensive tobuy directly from GVEA.The U.S. Department of Defense (DoD) should participate collectivelyfor the GFMC installations in the local electric utility’s (GVEA’s) nextrate-making process (anticipated to occur in 2005) to ensure that itsinterests are represented with regard to the demand charge, transmission system use charges, cost allocations, and rate structure.Installations should work and participate with GVEA to pursue development of wind energy.FWA, FGA, and EAFB should evaluate conversion of their heat distribution systems from steam to hot water, as hot water distribution maybe more cost-effective than steam.The next steps are to: develop sufficient project definition to support DD Form 1391 budgetlevel cost estimates for new coal-fired CHPPs at FWA and EAFB andfor two new coal-fired CFBs at EAFBupdate the life-cycle cost analysis for the DD Form 1391 cost estimateschoose alternative(s) and include them in the appropriate MilitaryConstruction program plan.v
