FNSB-ACEP Partnership
ObjectiveProvide 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
Energy Management Engineer“Work with Borough stakeholders and ACEP researchers to evaluate emerging and existing energy efficient technologies relevant to the
Borough.”
ACEPMission: “Develop and
disseminate practical, cost-effective, and innovative energy
solutions for Alaska and beyond”
Vision: “Alaska leading the way in innovative production,
distribution, and management of energy”
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.”

Pilot Project Progress and Plan
17
Identify potential pilot project sites
Select an appropriate system
Secure external funding to support pilot installation
Design and build installation
Purchase and install equipment
Operate system and collect data
Analyze performance data, disseminate results
Proposed Site – Big Dipper Ice Rink
• Demand Charges
• Year round heat load
• Chip Access
18
Proposed Technology – Volter 40
– Operates on wood chips (spruce and aspen)
– 40kW Electric
– 340,000 BTU/hr Thermal
– Small-scale, packaged unit suited for both railbelt and rural installations
– Load-following, but not grid-forming

Pilot Project Progress and Plan
25
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
Pilot Project – What Happened
26
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.
Pilot Project – Lessons Learned
27
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.
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
