Outline of this presentation
• Brief introduction to the Colorado PUC• Our energy regulatory priorities
– Stress energy efficiency– Stress renewable energy development– Employ progressive resource planning– Support advanced generation development
o CCSo CAES
– Accelerate state and regional transmission development

Caveat
• I am one of three equal commissioners• My positions are my own• I am confused by many things and have not made
up my mind on much at all• I don’t even agree with some of the things I say• Good advice: don’t believe everything you think
4
PUC Structure: Commissioners
• Three Commissioners• Appointed by the Governor• Confirmed by majority vote of State Senate• Serve four-year teams – may be reappointed• No more than two Commissioners from one political party• Judicial functions and legislative functions

Our State Energy Priorities• Boost Energy Efficiency
– Customer: education– Utility: engagement– Regulatory: incentive regulation; rate structure changes
• Stress renewable resources– State Renewable Portfolio Standard – Healthy renewables industry– A commitment to addressing climate change– Progressive resource planning at Commission
o PSCo ERP decisiono Inquiry into Tri-State resource planning oversight
• Advanced technologies development– Research and demonstration for carbon sequestration– Concentrating solar field at PSCo’s Cameo coal-fired plant– CAES and other storage strategies– Smart grid test bed in Boulder, Colorado
• Transmission development– SB 100– Western Renewable Energy Zones participation
10
The Challenges We Face
• Energy Supply
• Energy Efficiency
• Consumer Prices
• Climate Change
11
Colorado’s Balanced Approach
• Coal producing state (#8 of 50 states)• Natural gas producing state (#7 of 50 states)• Substantial wind and solar resources• Moderate electric rates• Governor with a focus on the
“New Energy Economy”

Colorado Approach to Electric Resource Planning
• “Least Cost Planning”
• Fuel Neutrality
• Utility models new portfolio
• Utility selects bid resources
• “Resource Planning”
• Clean Energy Preference
• Independent Evaluator
• Optional Post-bid Review
Old Rule New Rule
• New DSM emphasis
-- Resource Planning --
• Little energy efficiency
15
PUC’s ERP Decision for XcelEnergy
Major Decision Items
• Affirmed commitment to competitive bidding for resources
• Approved closure of two coal plants
• Approved large solar projects (200 - 600 MW)
• Continued growth of wind
• Assumed future CO2 price in modeling ($20/ton + 7% growth)
16
PUC’s ERP Decision for Black Hills
Major Decision Items
• Affirmed commitment to competitive bidding for resources
• Permitted Black Hills to own and construct half of new resources
• Modified competitive bidding process to eliminate “Phase II”
• Assumed future CO2 price in modeling ($20/ton + 7% growth)
• Appointed Independent Evaluator
• Result of bidding:200 MW contract to BH IPP for CTs and CCs
17
The Challenges We Face
• Energy Supply
• Energy Efficiency
• Consumer Prices
• Climate Change
18
Boosting Energy Efficiency
• Utility: Engagement
• Customer: Education
• Regulation: Make rate structure changes
• New Development: “Smart grid”
19
Utility Engagement
• Energy Efficiency goals in legislation
• Recent Commission rules establishing: – Bonus mechanism– Expedited cost recovery
• Tie-in EE to utility resource planning
• Overall: utility should make efficiency a business

• Use: 100 MW(ac)/mile2
• Colorado Peak Integrated Demand: 11GW
• Result: 110 mile2 required land area

But what if 11 GW of solar were spread around the state in 100 MW installations?
It might look like this...
