12. Maps and Resource Potential from Colorado Governors Energy Office Information on Wind and Solar Bids from Xcel Energy Repowering and Decarbonizing Colorado Colorados Wind Potential Approx 96 GW Colorados Solar Potential Over 200 GW To Meet Peak Demand, Colorado Needs About 12 GW (12,000 MW) Colorado has the Potential for Over 300 GW of Wind and Solar…. And Many Companies Ready to Build Projects. Clearly, we can largely decarbonize our electricity--IF we decide to do it !

22. RenewablesYES A Remarkable Volunteer Effort

23. Key Questions for Citizen Experts: 1)How Much Renewable Energy? 1)What Will it Do to Rates?

24. Boulders Load 100 MW baseload 100 MW Baseload i.e. Coal

25. 20% Renewable Electricity 100 MW baseload

26. 30% Renewable Electricity 100 MW baseload

27. 30% Renewable Electricity Around 30% Renewables, Baseload Coal & Nuclear make no sense. 100 MW baseload

28. 50% RE. 0 Battery. 4% Overgeneration

29. How do we get to 100% Renewable Electricity? To get to 100% - practical tech isnt obvious. % Renewable s (variable generation) Controllable Generation SolarWindEtc Short Storage (seconds to days) Tech Exists Long Storage (weeks to years) No Tech Up to 25% Mix Nimble Peaking. Static baseload. Yes Mostly wind OK Up to 50% Nimble Peaking Fuel gas. More. Must Mix Wind & Solar Up to 75% Nimble Peaking Fuel gas. And More Yes Up to 100% Nimble Peaking With nimble fuel And More Yes Yes, but…

30. Xcel…Chained to Coal 2011 to 2018 Approx. $400 Million Pollution Controls for Brush and Hayden (Wont Address CO2) Dockets 10M-245E and 11A-325E Colorado PUC Over 1800 MW of Coal Through 2033 Pueblo 1170 MW Retire 2033, 2035, 2069 Brush 505 MW Retire 2041 Hayden 237 MW Retire 2025 and 2036 Craig 84 MW Retire 2040 and 2039 Xcel Path: Approx 60% Electricity from Coal in 2011 and 35% in 2030

31. Muni Renewable % (at Rate Match) Xcel Renewable % (under 2010 RPS) Graphs by Renewables Yes Using Data from Xcel Provided to City of Boulder and in PUC Dockets Renewable % Comparison Xcel v Boulder Municipal at Rate Parity

32. Fossil Fuel Use Xcel Projections v Boulder Muni at Rate Match Graph by Renewables Yes Using Data from Xcel and Modeling Projections; Source data available on request. Xcel Total Fossil Fuel Use Muni Total Fossil Fuel Use

33. 2) The True Cost of Coal = ????? Cents/kwh 1)The Delivered Price of Coal Going Up >10%/Year (2004-2009) Actual Coal Cost > 10%/Year Xcel Models Coal Cost <2%/Year

34. Municipal Rates? Likely to Meet or Beat Xcel: Up to 40% Renewable Energy Reasonable Acquisition Costs Reasonable Stranded Costs Bond Rates Under 8% Details at www.renewablesyes.org Hundreds of Modeling Runs Done in 2011: Cannot Get Further Refinement without Final Acquisition and Stranded Cost Numbers

35. Municipal Reliability? Munis Typically Have Better Reliability Than IOUs. Colorado Springs, Loveland and Fort Collins All Have Substantially Better Reliability Than Xcel Has in Either Boulder or Denver

36. RequirementXcelMuniB Path to 100% Renew. No. Chained to coal. Yes. Extensive modeling. Minimize Carbon No. 30% reduction 2018. Chained to coal. Yes. 50 – 80% redction coal to gas = 50% ReliabilityYes Yes. Competition. Hire experience. Rates Competitive ??? And up 7% so far this year Yes. Extensive modeling. Rates Stabilized No. Business model Yes. Lots of renewables… Local Control NoYes. Our voice can be heard Growable beyond Boulder n/a. Nothing to grow. Yes.
