renewable energy assessment
project description
• boundaries: Josephine and Jackson Counties* • renewable technologies reviewed
− solar electric (PV and thermal) − wind − energy efficiency − Biomass − hydro − geothermal − landfill gas − anaerobic digestion
• data collection: expert and stakeholder interviews and public data sources
*except for anaerobic digestion
renewable energy assessment
variables for assessment • energy type: baseload / intermittent / dispatchable • likely technology • levelized cost • energy return on energy invested • carbon intensity (CO2e / kWh) • risks
− Uncertainty − byproducts (e.g., air or water emissions) − negative impacts on people and habitats − regulations
• benefits − byproducts − positive impacts on people and habitats − incentives
renewable energy assessment
context for a renewable energy assessment
• consumption trends • energy prices and security • policy factors • incentives and financing • distribution and interconnection • technology and market factors • local jobs • GHG emissions
context
results of regional GHG inventory
context
comparison of per capita emissions
context
carbon = energy = opportunity
• see the business case now − ENERGY STAR: lifetime savings of more than $250
billion dollars for actions through 2009 − McKinsey: U.S. can reduce GHG emissions by ~30%
solely with cost-effective investments and actions − RVMPO sponsored truck outreach center in Medford − Clean Energy Works − Dry Creek Landfill LFG to transportation fuel − Brammo, Inc.
• position for opportunity in the future

most feasible technologies
• solar (PV and thermal) • wind • energy efficiency • biomass • hydro • anaerobic digestion • geothermal • landfill gas
renewable technologies
geothermal
• not enough thermal potential in Jackson and Josephine Counties to generate electricity
• opportunity to use geothermal in buildings for heat
renewable technologies: exclusion
landfill gas
• existing resource already being utilized at Dry Creek Landfill − evaluating gas for transportation
• closed landfills are not producing enough gas to justify investment
renewable technologies: exclusion
energy efficiency • energy type: baseload
• likely technology: numerous
• future potential: 64 – 100 aMW
• levelized cost: $0 – $106 (average <$35)
• risks: first costs, lack of reliable information, split incentives, sometimes a long payback, lack of easily accessible financing
• benefits: vast potential, readily available, decrease load (but not a supply), cost-effective compared to new generation, job creation (17/$1 million invested), equitable distribution of economic benefits

solar electric
• energy type: intermittent, peak matched • likely technology: small-scale PV • future potential: 35 MW (5% of roof space) • levelized cost: $90 - $154 • EROEI: 3 – 6x • C-intensity: 50 – 59 kg CO2e / MWh • risks: cost, incentives uncertainty, land use and
utility interconnection (large-scale systems only) • benefits: low O & M, carbon-neutral, no air
emissions during use, various incentives, few barriers to entry (for small scale), RECs, job creation (14 / $1 million invested)

wind • energy type: intermittent • likely technology: small-
or utility-scale • future potential: 27 MW • levelized cost: $44 - 91 • EROEI: 18 – 34x • C-intensity: 6 -14 kg CO2e / MWh • risks: land use and ownership, noise, aesthetics
issues, development of remote and pristine areas, interconnection, avian and bat mortality, permitting
• benefits: carbon-neutral, no air emissions during use, various incentives, RECs

biomass
• energy type: base or dispatchable • likely technology: direct-fire CHP • future potential: 5 – 14 MW • levelized cost: $65 - $151 • EROEI: 3 – 27x • C-intensity: TBD • risks: regulatory, ability to source cost-effective
feedstock, feedstock availability, carbon-neutrality questioned, emissions, odor, noise, habitat disturbance
• benefits: local jobs, displaces open burning, reduces fire risk, various incentives, RECs
renewable technologies: opportunity
biomass: feedstock availability
• availability of cost-effective feedstock is the main driver of feasibility
• based on current economic and market conditions there is a lack of cost-effective feedstock - current = 35,000 bone dry tons (BDT) at $65 / ton - 6 months ago = 70,000 BDT - difference is the result of demand in China’s pulp
markets - ~$40 / BDT cost effective line
renewable technologies: opportunity
• energy type: baseload, intermittent, dispatchable • likely technology: incremental • future potential: 2.4 MW • levelized cost: $10 - $136 • EROEI: 170 – 280x • C-intensity: 3 – 18 kg CO2e / MWh • risks: regulatory, flooding wilderness, water rights,
disrupt water flow, temperature gradients, turbidity, various permits (location dependent), fuel source dependent on weather and climate, interconnection
• benefits: carbon-neutral, no air emissions, RECs, high EROEI
renewable technologies: opportunity
hydro
• opportunity = incremental projects - Emigrant Dam (1.8 MW) - Talent Irrigation District (0.6 MW) - Eagle Point Irrigation District (requires study) - Medford drinking water supply line (requires
study)
renewable technologies: opportunity
hydro
anaerobic digestion
• energy type: baseload • likely technology: dry or wet AD • future potential: 0.5 MW • levelized cost: $36 - $115 • risks: feedstock sourcing, air
and water emissions, permitting, logistical issues
• benefits: renewable electricity orvehicle fuel, utilizes waste feedstocks, environmental commodities (RECs, RINs, offsets), soil nutrients, diverts materials from landfill, and lower c-intensity versus landfill biogas collection

conclusions
regional electricity use vs. generation sources
context
implications for region, uses for assessment
• consensus-building (economic opportunity) • citizens, businesses and government need to
work together to find win-win opportunities (upcoming working groups)
• identify opportunities in key public and private systems
• positioning the region to seek grants • public education
