Governor’s Energy Office, Renewable Energy Distribution Infrastructure (REDI) Report
Presented by: Adam Cahn, Government Intern
Governor Ritter issued an Executive Order on April 16, 2007, re-creating the Governor’s Office of Energy Management and Conservation (originally created in 1977 to promote energy conservation in Colorado) as the Governor’s Energy Office (GEO). The GEO’s mission is to lead Colorado to a New Energy Economy by advancing energy efficiency and renewable, clean energy resources. The GEO was awarded a grant from the Department of Energy’s Office of Electricity Delivery and Energy Reliability to support the REDI Project. The results of the project were compiled into the REDI report, an analysis of the issues facing Colorado’s electric power sector as it strives to meet the goal of a 20% reduction in CO2 emission by the year 2020 from a 2005 base.
As an introduction on accessibility of renewables on the grid, our green tech host Kris Weisenfeld brought up the Pickens Plan. Considered a pioneer in wind generation in Texas, T. Boone Pickens had plans to build a 4MW wind farm in the Texas Panhandle through the Mesa Energy company. Although he’s purchased wind turbines and started to install them, the complexities of getting the transmission in place is holding the Pickens project back until 2013. Similarily Colorado REDI report tackles the issues of transmission and technology factors. Utility based power must deal with transmission. Renewables can also increases distances since the optimal renewable sources are not always close to their destination loads.
As a result of Senate Bill 91, the REDI report was created. The report identified 10 Generation Development Areas (GDAs) for renewables in Colorado. From these areas, 8 GDAs support wind with a total of 96GW capacity or 8 times Colorado’s current peak energy usage. The remaining two GDAs support solar and if completely covered with Concentrated Solar Power (CSP) would equal 1300 GW. If only 2% of the land was used for solar it could host 26GW of capacity, more then twice Colorado’s peak usage. The report also includes information from over 450 technical reports produced in cooperation with NREL and the Department of Energy.
Technology is also changing the landscape of alternative energy capabilities on the grid. The SB91 report uses the 2007 NREL wind capacity estimates for wind turbines designed at a 50 m hub height. This is a conservative estimate with new technology for wind becoming available. New estimates from NREL indicate that 80 m hub height increases capacity from 96,000 MW to 300,000 MW or over 3x increase in capacity. Adam also showed some great photos from the Vesta production floor and train-based transportation of these massive wind turbines segments from the factory to their ultimate operational destination.
The REDI report addresses Colorado’s renewable energy portfolio (REP) 2020 goal: 20% reduction of CO2 emissions by 2020 based on 2005 emissions. Today Colorado has made significant progress. Adam showed a chart of CO2 emissions with an increasing curve of where Colorado was going and of how we achieved reduced consumption back to baseline status. This has been achieved with renewable energy and demand side policy to optimize energy usage. Another aspect of energy consumption and limiting CO2 for the 2020 goal is that Colorado is expecting to grow in population from 5.2M today to 6.2 M in 2020. The demand (medium) forecast will go from 60 GWh to 80 GWh. Given these challenges, the strategy for Colorado is to develop significantly more renewable energy and make it available through new transmission lines at higher & more efficient voltages ( 230 KV and 345 KV). Some of the other key recommendations are:
- Increase renewable energy development, including utility scale wind & solar generation
- Increase high-voltage centers from renewable generation sources to high-demand load centers
- Generate natural gas power strategically to supplement naturally variable renewable energy
- Reduce strategical utilization of coal-fire plants and/or retirement of least efficient coal-fired units
If you are interested in more details on the REDI Report go to the Govenor’s Energy Office main site Recharge Colorado where you can view the utube video or read the pdf REDI online report.
Our greentech audience had some interesting questions for Adam. One alternative to utility based is ‘localized generation’, although not a focus for this report the approach is popular in Colorado and requires knowledge and maintenance by the local provider. The REDI report also indicates that although some lines can be upgraded in place to higher voltages, most of the recommendation are pointing to build-out of new transmission capabilities in new areas or beside existing lines. For this build-out, underground buried lines are preferred by many. However, the cost to do so is over $6M per mile, and 2 to 4 times more expensive then overhead power lines. Colorado is advancing to higher voltage transmission levels and looking to use improved aluminum transmission lines. Worldwide the build-out of capacity is undergoing massive change. Ultra-High Voltage transmission (1000 KV AC +) as prototyped in China, are looking to improve range beyond the traditional 500 mile limit. At this point in time it looks like Colorado is not as challenged as China in terms of distance but it will be interesting to track advanced in both AC and DC transmission abroad.
SunTrac Solar - Revisited
Presented by: Adam Rentschler, CEO
As Suntrac Solar is in a very dynamic phase of corporate development, we invited them back for an update (see our April 2010 blog on their first presentation) and to allow them to benefit from the “Wisdom of the Crowd” (i.e. you).
SunTrac Solar manufactures the world’s most efficient flat-plate solar thermal panels in Golden, CO. They have shrunk utility-scale parabolic trough technology and put in into a traditional flat-plate collector box. Their core product creates high temperature hot water for commercial and industrial applications.
Overall the discussion included an excellent feedback on new market entry, state by state legislation/rebates/incentives, competitive pricing related to volatility (natural gas/propane) and overall market strategy (risk mitigation versus value creation). Thanks to everyone for participating and offering leads & information to SunTrac. Our local community of experts provided thoughtful information to help develop and support our local green tech companies.

ION Engineering is commercializing proprietary technology for removing CO2 and other contaminants from gas streams found in natural gas, syngas, fossil fuel power plant flue gas and industrial processes. ION founders include inventors from the University of Colorado and a management team with strong start-up and industry experience. ION is working with global partners to develop applications for their core technology, based on solvents combining ionic liquids and amines. The properties of ION’s solvents offer advantages that lead to process improvements with lower capital requirements and reduced operating costs. Advantages over existing and emerging technologies include improved capture performance, life-cycle cost advantages ranging from 25% to 50%, reduced water and energy use, and a smaller footprint.
ION has found a lower cost solution to address reduction of CO2 and other contaminants in industrial/power plants as compared with current gas-treatment and Carbon capture solutions. Natural gas is cleaner then coal (half the CO2) when used as an energy source but over 40% of natural gas reserves have CO2 and H2S that must be cleaned. Additionally Carbon capture is currently a very expensive approach to CO2 reduction. Currently the 95% of the industry uses aqueous amine solvents to ”sweeten” (reducing sour smell) by removing H2S and CO2 from natural gas.
The solvent approach developed by ION engineering uses a ionic liquids and amines that are chemically and thermally stable. Ionic liquids use organic salts that are non-volatile and liquid at room temperature. Conventional technology uses amines to bind to CO2 in an absorber unit and then channels the solvent to a regenerator where the stream is heated and CO2 is captured. The ION approach replaces the water used in the traditional systems with an ionic liquid. The system also saves in the amount of aqueous amine but replaces with a more expensive ionic liquid. Overall the technology has significant benefits, lowering operating and capital cost in the range of 25-50% (an example was shown for a gas processing unit with 15% CO2 having annual savings of 3.6 Mil.).
The addressable market is dependent on regulations and today there are 23 states where green-house gas emissions are restricted. Legistlation and the perception of traditional energy issues (such as the gulf spill) will shape our next energy policy. ION expects to leverage their technology across a spectrum of users. Starting with small volume plants (<100 MMscf or million standard cubic feet per day of gas) by leveraging the strong operating drivers to implement natural gas cleaning. Larger facilities can be retrofitted and have major justification on cost alone to upgrade. Finally, Coal & Gas power plants could use this technology with carbon capture to reduce their equipment footprint and operating cost.
GenGreen LLC – Sustainable Living Made Local & launch of BigGreenDeal.com
Presented by: Charisse McAuliffe, Founder & CEO
GenGreen LLC was founded in Fort Collins, CO three years ago by Charisse McAuliffe with the intention to help make it easier for people to find the resources they need to live a sustainable, locally focused life. Today, GenGreenLife.com is the largest directory of verified green businesses and organization in North America with over 70,000 listings. GenGreen is also the creator of one of the most popular green mobile applications called “Find Green”, available on iPhone, Android, and Blackberry platforms. GenGreen just launched their newest product, BigGreenDeal.com which is where GenGreen certified members offer exceptional discounts on products and services in a ‘deal of the day’ type transaction. GenGreen will soon be rolling out BigGreenDeal.com on a local level starting in June.
To-date GenGreen has grown impressively since they presented at the inaugural Colorado Green Tech meetup. They have over 70,000 listing in 25+ categories ranging from Green Events to Travel/Eco-tourism to Babies/Kids, Health&Wellness, Carbon Offsetting and Food/Dining. Their “Find Green” application along with the traditional web site tools help users find their product with confidence that they are certified green. GenGreen has had great success with their current iPhone application but also have a future application on the android phone that is close to be released. The web and mobile channels not only find your desired green products but also help find services that are close to you, such as the closest organic restaurant or closest recycling plant.
Their latest venture is called the BigGreenDeal. This new web offering allows for service /product provider to offer discounts to the GenGreenLife audience. An example of a product show in the presentation was a belt made from recycled tires. The offer made to consumers is 51% discount with an expiry time remaining. This product is GenGreen Approved and has fully supported information as part of its certification. As BigGreenDeal uses a similar model to middlemen like ebay or amazon, they take a cut of all transactions. Their current plans is to launch into 50 local markets and be the dominate player in green product search, sales and discounting.
