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
![Page 4: Colorado’s Solar Policies Western Solar Policy Dialogue WCPSC Meeting 2008 Presentation of Ron Binz, Chairman Colorado Public Utilities Commission June.](https://reader038.fdocuments.us/reader038/viewer/2022110401/56649e295503460f94b16ca2/html5/thumbnails/4.jpg)
The Colorado PUC
• Independent agency, created in the constitution• Three Commissioners, appointed by the Governor• Four year terms• Partly judicial, partly legislative• Ninety-member staff is an agency within the
Department of Regulatory Agencies
The Public Utilities Commission's mission is to achieve a flexible regulatory environment that provides safe, reliable and quality services to utility customers on just and reasonable terms, while managing the transition to effective competition where appropriate.

What are the primary drivers behind the desire to increase solar activity in your state?
What is the level of consumer demand or RPS-driven demand for utility solar generation in your state?
For all those who claim solar is just too expensive, how are you making it a cost-effective generation option?
How are the utilities under your regulation thinking about integrating solar resources into their business model?
What were the major implementation barriers with utilities and then separately with the solar industry?
What suggestions do you have for others about hashing out the complex details with utilities and the solar industry?
How have rising costs for new generation, including the imminence of carbon controls and/or taxes, changed utilities’ and regulators’ outlook on solar generation?
Are there flaws in the implementation of policies, incentives, or verification systems that you put in place that you would caution other states to avoid?

– Net metering required
– Rebate specified
– Rate impact cap
• Political Leadership– Governor Ritter
• New Energy Economy (2006)
• Climate Change Action Plan (2008)
– General Assembly• Doubled RES requirement to 20% (2007)

HB 1281 – Colorado’s Renewable Energy Standard
• IOUs -- 20% renewables by 2020• REAs, Munis -- 10% renewables by 2020• For IOUs, 4% of renewables must be solar, half
on-site• 1.25x for in-state resources• 1.5x for community-based projects• 3.0x for REAs use of solar• Maximum rate impact 2% for IOUs, 1% for Munis
and REAs

(b) THE COMMISSION MAY GIVE CONSIDERATION TO THE LIKELIHOOD OF NEW ENVIRONMENTAL REGULATION AND THE RISK OF HIGHER FUTURE COSTS ASSOCIATED WITH THE EMISSION OF GREENHOUSE GASES SUCH AS CARBON DIOXIDE WHEN IT CONSIDERS UTILITY PROPOSALS TO ACQUIRE RESOURCES.
(3) (a) (I) ENERGY IS CRITICALLY IMPORTANT TO COLORADO'S WELFARE AND DEVELOPMENT AND ITS USE HAS A PROFOUND IMPACT ON THE ECONOMY AND ENVIRONMENT. IN ORDER TO DIVERSIFY COLORADO'S ENERGY RESOURCES, ATTRACT NEW BUSINESSES AND JOBS, PROMOTE DEVELOPMENT OF RURAL ECONOMIES, MINIMIZE WATER USE FOR ELECTRIC GENERATION, REDUCE THE IMPACT OF VOLATILE FUEL PRICES, AND IMPROVE THE NATURAL ENVIRONMENT OF THE STATE, THE GENERAL ASSEMBLY FINDS IT IN THE BEST INTERESTS OF THE CITIZENS OF COLORADO TO DEVELOP AND UTILIZE SOLAR ENERGY RESOURCES IN INCREASING AMOUNTS.

![Page 15: Colorado’s Solar Policies Western Solar Policy Dialogue WCPSC Meeting 2008 Presentation of Ron Binz, Chairman Colorado Public Utilities Commission June.](https://reader038.fdocuments.us/reader038/viewer/2022110401/56649e295503460f94b16ca2/html5/thumbnails/15.jpg)
Elements Of A State Energy Strategy
• Boost Efficiency– Customer: education– Utility: engagement– Rate structure changes
• Stress renewable resources– Regulators and utilities with a commitment to
addressing climate change– State RPS– Progressive resource planning at Commission– Healthy renewables industry
• Advanced generation development– Research and demonstration for carbon sequestration

Projected Colorado Electric Energy Growth 2007-2025
![Page 26: Colorado’s Solar Policies Western Solar Policy Dialogue WCPSC Meeting 2008 Presentation of Ron Binz, Chairman Colorado Public Utilities Commission June.](https://reader038.fdocuments.us/reader038/viewer/2022110401/56649e295503460f94b16ca2/html5/thumbnails/26.jpg)
The Take-Aways
• Colorado’s demand for electric energy services is projected to grow 60% in the next seventeen years.
• Think of this curve as demand for energy services denominated in kilowatt-hours
• Projection does not include transportation applications for electricity (plug-in hybrids).

“…because we want to be able to effectively manage the integration and development of concentrating solar thermal with energy storage, … we request that the Commission limit the acquisition of this new clean energy technology to 600 MW during [2007-2015] and that it be brought on line in increments over time.”

– Solar requirements
– Net metering policies
– Utility rebate requirement for on-site solar
• Rate structure challenges• Industry fears of solar boom and bust• Intra-industry competition• Customer understanding and acceptance

Why should we subsidize rich people to put solar panels on their roof…?
• Solar must be seen as a system resource– Solar adopters are system solar hosts
• We must decode the “subsidy” notion– Solar hosts probably pay more for electricity

• Regulators must get out in front on message• Option: target some roof-top solar to low-
income projects
