Energy Economics Intro • How much does it cost? • Who pays? MAFA
Energy Economics: Key Assumptions – Looking Forward • Oil prices • Natural gas prices • Cost of project development • Environmental considerations • Economic discount rate; what is the opportunity cost of public or private funding MAFA
Energy Economics:Oil Price Reference Forecast Illustrative prices: $110/bbl at refinery =$2.62/gal at refinery (~$19/mmbtu) =$3.00/gal refined product rack (~$22/mmbtu) =$3.20-$7.50/gal to local storage/utility (~$23-54/mmbtu) =$4.00–$9.00/gal delivered to bldgs (~$29-65/mmbtu) MAFA

Energy Economics: Will downsizing a hydro development on a river basin make it more affordable? How do you measure affordability? Total $ or ¢/kWh Sources: Susitna Hydroelectric Project, Project Evaluation, Interim Memorandum, Table 1 Summary and Appendix B: Detailed Cost Estimates (March 2009); These cost estimates include transmission system interconnection and substation upgrades (Ester, Willow, Knik Arm, University and Devil Canyon) and $45M for a new Energy Management System to help integrate the resources with the balance of the interconnected system. MAFA
Energy Economics: How well do we estimate the cost of hydro Large project cost risk zone Continuing challenge of whether & how To adjust *project cost* estimates To account for large project cost underestimation risks including: Low end estimates Project development cost overruns Source: MAFA Analysis of AEA Hydro Database, 2009 MAFA
Environmental Considerations • Project Development • Site selection, local land use considerations • Time to develop • Local environment/habitat mitigation considerations • Mitigation requirements • Hydro water sharing, air/water cooling for combustion driven electrical generation • Emissions • Air pollution: sox, nox, particulates, GHG, mercury (Hg), etc. MAFA
Project Development Source: MAFA Analysis (2009) of EIA AEO Technical Documentation-Alaska Hydro Resources (2003) Available for Development [Measured in MW of electrical capacity] Around 1 in 8 promising hydro sites *might* be available for development due to conflicts with parks and fishing resources MAFA
Project Development Challenges Includes Chakachamna Chakachamna should be reclassified to 50% dev’t probability (to correct error in IHRED framework) leaving roughly 3.2% in 90% probability Includes Susitna EIA AEO Hydro Resources report (IHRED, 2003) estimates 26% in mitigation costs need to be added to basic Watana dam construction costs to account for fish and wildlife habitat and water monitoring requirements to achieve permit. That amounts to roughly $1B on a $4B construction cost estimate. MAFA
Project Development Challenges:Mitigation allowance and licensing budget EIA AEO U.S. Hydro Resources Report (IHRED, 2003) estimates 26% needs to be added to basic Watana dam construction costs to account for fish and wildlife habitat mitigation and water monitoring requirements to achieve permit at 1000MW scale. At $8.4 billion for the 1200 MW scale, this amounts to roughly $2 billion. Internal estimates at 1200MW scale contain $200 million mitigation allowance. Licensing effort estimated at 6.5% of construction cost at 1000MW scale – amounting to roughly $450 million on $6.9 billion low Watana 600MW construction cost estimate; or $325 million on low low Watana 500MW construction cost estimate of roughly $5 billion. These estimates may be low. Licensing percentage for smaller scale project likely to be higher as smaller scale has higher capital cost per unit of water impounded raising conflicts between limited water for habitat mitigation vs. water for electricity, especially as hydroelectric interests attempt to capture more water for winter peak electrical demand in order to deliver on promise of “cheap” electricity when most needed. MAFA
Economic Discount Rate • What is the value of a $1 today compared to a $1 a year from now, 10, 20, 30, 40, 50 years from now? What opportunities do we give up? • Range of estimates: • Diversified Permanent Fund = 5% real • Federal OMB = 7% real • AEA B&V IRP = 7% nominal; ~4.5% real • Others… • Zero or negative; long run social discount rate 3% • How we *finance* the development and construction is a separate and distinct analysis MAFA
Illustrative Energy Economics: Long Run Levelized Cost • Long-run Levelized Cost of Energy comparison • Equivalent Uniform Annual Cost (EUAC) methodology • Attempts to create a metric that you can compare to today’s unit cost of c/kWh or $/mcf • Components • Capital • Operating • Fuel • Regulation MAFA
Illustrative Scenario 1 [$3.50HH, $24CO2, 0% CapExRisk, 5% real] MAFA
Illustrative Scenario 2 (~AEA B&V IRP) [$4.50HH, $84CO2, 0% CapExRisk, 4% real] MAFA
Illustrative Economics: What factors drive the results • Capital cost estimates for large capital/low fuel cost technologies (hydro, coal, tidal, wind, biomass, geothermal, CTL, GTL) can make the project very competitive or very expensive compared to natural gas – and the capital costs estimates appear to be very sensitive to who is sponsoring the estimate • The price of natural gas and its potential volatility is a key factor in evaluation of alternatives in Southcentral, including end-use efficiency, especially related to heating of residential, commercial, government, institutional and industrial buildings. • Coal prospects are sensitive to assumptions about CO2 costs and natural gas prices MAFA
