Feasibility Study - ScreeningSection 2.2 Basic Power Plant DesignObjectivesProvide tribal investment opportunity (diversification)Provide tribal employment opportunitiesEnhance economics of other tribal operations (fishery, headquarters campus, future industrial/energy park)ResourcesLimited landPoor wind, geothermal and solar potentialStrong logging and forest products industry in the regionMarketsWisconsin regulations prohibit retail power salesFishery, tribal headquarters campus and casinos are potential users of waste heatState has initiatives to mandate accelerated use of renewable energy ConclusionA biomass renewable energy project based on burning residues and waste from logging and forest products manufacturing operation is consistent with tribal objectives and resources, and consistent with state renewable energy initiatives.

Section 2.2 Basic Power Plant DesignFeasibility Study - FeasibilityIdentification of potential power purchasers and assessment of level of interestResource assessment (sources, volumes, reliability, pricing, fuel value, current uses)Fuel supply strategy (for biomass projects)Candidate technology assessment (equipment manufacturers, experience, fuel compatibility, impacts, site requirements, preliminary economics screening)Project structure strategy (ownership, operation and staffing responsibility, etc.)Market development strategy (regulatory constraints, mandates, incentives, transmission constraints, competition)Preparation of detailed site selection criteria (musts and wants re: proximity to sales points, proximity to fuel source, transportation infrastructure, utility infrastructure, environmental considerations, land and buffer requirements, etc.)Site Screening / Site Selection (prime and back-up, if appropriate)Permitting StrategySocio-economic and environmental impactsEconomics
