3 FNSB-ACEP Partnership Objective Provide coordination of programs and projects involving the development, implementation, and evaluation of energy efficiency, energy delivery, and alternative and renewable energy systems in FNSB. 3

4 Biomass Pilot Project Motivations Fairbanks Comprehensive Economic Development Strategy (CEDS) COMMUNITY PRIORITY #1: Lower and stabilize FNSB energy costs by expanding the energy portfolio with a focus on local resources. ACEP Mission: Develop and disseminate practical, costeffective, and innovative energy solutions for Alaska and beyond Vision: Alaska leading the way in innovative production, distribution, and management of energy Energy Management Engineer Work with Borough stakeholders and ACEP researchers to evaluate emerging and existing energy efficient technologies relevant to the Borough. 4

25 Pilot Project Progress and Plan Funding Sources: $290,000 in EETF Grant + $290,000 required FNSB Match = $580,000 $218,000 USFS Wood Innovations Grant award $120,000 FNSB Energy Reductions Projects Fund 25

26 Pilot Project What Happened Things that we did right: Identified site and technology and testing plan. Funding awarded and appropriated. EPA, DEC, UL, GVEA Electrical Interconnection, Customs, compliance plans. Assembly approval of non-competitive procurement to meet grant scope of work. Project discontinued by FNSB: Original Scope of Work exceeded budget, FNSB procurement standards limited ability to negotiate. Equipment provider not comfortable with standard contract language. 26

27 Pilot Project Lessons Learned Evaluate internal structure for suitability for research type project. Look for cost drivers. If partnering, carefully consider which entity can best serve as lead. Stress consensus on legal terms and conditions as early as possible in project. 27

28 Why a Pilot Project should still be pursued Alaska energy costs are high Biomass is plentiful and sustainable New technology to produce commercial scale electricity from wood Reduced costs to building operators Commercial economic activity Reduce impact of biomass energy on air quality 28
