    • Drivers of the New Transmission System CLE International Ritz Carlton, Denver March 19, 2010 by: Ron Miller, P.E.
    • RE Project Ingredients • Environmentally-permittable • Technically-feasible • Financially-viable … and the linchpin of any utility-scale project is TRANSMISSION of energy to the end- user market Copyright© 2010 Ronald L. Miller. Material can be shared or copied with attribution to the copyright holder. http://www.linkedin.com/pub/ron-miller-p-e/4/842/580 2
    • Market Drivers • U.S. electricity demand, coal consumption, & electricity prices • Renewable resource location • Federal direction • State renewable portfolio standards • Price convergence • Transmission use and constraints Copyright© 2010 Ronald L. Miller. Material can be shared or copied with attribution to the copyright holder. http://www.linkedin.com/pub/ron-miller-p-e/4/842/580 3
    • U.S. Electricity Demand, Coal Consumption, & Electricity Prices • Key electricity consuming areas: Texas, California, Midwest • Key coal consuming areas for electricity: Texas, Midwest, Southeast • Highest prices for electricity: Northeast, California, Texas These key criteria define the “target market” for future renewable energy destinations Copyright© 2010 Ronald L. Miller. Material can be shared or copied with attribution to the copyright holder. http://www.linkedin.com/pub/ron-miller-p-e/4/842/580 4

    • Coal Consumption High coal, NOX, SOX, CO2 Source: National Priorities Project Database Copyright© 2010 Ronald L. Miller. Material can be shared or copied with attribution to the copyright holder. http://www.linkedin.com/pub/ron-miller-p-e/4/842/580 6
    • Average 2008 Residential Electricity Price in U.S. High energy price areas Copyright© 2010 Ronald L. Miller. Material can be shared or copied with attribution to the copyright holder. http://www.linkedin.com/pub/ron-miller-p-e/4/842/580 7
    • U.S. Residential Electricity Price Historical Trend Growing energy use/price, even with DSM/energy efficiency Copyright© 2010 Ronald L. Miller. Material can be shared or copied with attribution to the copyright holder. http://www.linkedin.com/pub/ron-miller-p-e/4/842/580 8
    • Renewable Resource Location • Wind in Intermountain / Great Plains area, California • Solar in desert Southwest • Geothermal in Nevada, California • Best resources tend to be in more remote locations, not near major population centers, areas of highest coal use, or areas with highest electricity prices Copyright© 2010 Ronald L. Miller. Material can be shared or copied with attribution to the copyright holder. http://www.linkedin.com/pub/ron-miller-p-e/4/842/580 9

    • Federal Direction • Ensure that 10 percent of the nation's electricity comes from renewable sources by 2012 and 25 percent by 2025 • Implement an economy-wide cap-and-trade program to reduce greenhouse gas emissions 80 percent by 2050 • Reduced GHG in tandem with retiring coal plants opens a window for alternative sources for energy mix, if it can be delivered to the end-user market Copyright© 2010 Ronald L. Miller. Material can be shared or copied with attribution to the copyright holder. http://www.linkedin.com/pub/ron-miller-p-e/4/842/580 14
    • Renewable Portfolio Standards Copyright© 2010 Ronald L. Miller. Material can be shared or copied with attribution to the copyright holder. http://www.linkedin.com/pub/ron-miller-p-e/4/842/580 15
    • Price Convergence Copyright© 2010 Ronald L. Miller. Material can be shared or copied with attribution to the copyright holder. http://www.linkedin.com/pub/ron-miller-p-e/4/842/580 16
    • Grid Use • Grid built to handle transmission & distribution needs for a utility’s service territory with ties to only adjoining utilities • Never intended to handle cross-country transmission of energy • Transmission investment and rate of return have historically lagged generation Copyright© 2010 Ronald L. Miller. Material can be shared or copied with attribution to the copyright holder. http://www.linkedin.com/pub/ron-miller-p-e/4/842/580 17

    • Transmission Issues • According to North American Reliability Council new generation supplies are forecast to outpace transmission, constraining wind development with a planned 145,000 megawatts of capacity over the next 10 years • Generation growth over 10 years: 21% • Transmission line growth over 10 years: 10% with 1,700 circuit miles Copyright© 2010 Ronald L. Miller. Material can be shared or copied with attribution to the copyright holder. http://www.linkedin.com/pub/ron-miller-p-e/4/842/580 20
    • Transmission Solutions • Texas approved a $4.9 billion transmission system upgrade moving power from West Texas to major population centers. Capable of transmitting 18,500 MW of wind power. Cost: $4/month/retail customer • National upsurge in transmission investment due to Congressional action to increase transmission project allowed rate of return Copyright© 2010 Ronald L. Miller.

    • Value • North / South grid allows leveraging natural variability of wind throughout Great Plains and complementary solar, just as a portfolio of different stocks lowers overall volatility • East / West grid allows delivery to the target markets with greatest value to producers and producing states Copyright© 2010 Ronald L. Miller. Material can be shared or copied with attribution to the copyright holder. http://www.linkedin.com/pub/ron-miller-p-e/4/842/580 24

    • Summary • Environmental concerns are leading generation source changes • Renewable resources need connections to end-user electric markets which offer higher prices to spur renewable growth • Price convergence will multiply the need for transmission to accommodate renewable energy generation • Energy storage will dampen RE variability, adding greater reliability and value to its generation Copyright© 2010 Ronald L. Miller. Material can be shared or copied with attribution to the copyright holder. http://www.linkedin.com/pub/ron-miller-p-e/4/842/580 27
    • Summary, cont’d. • Choice between less-productive, local renewable resources vs. highly-productive resources connected to high-demand, high-priced markets • Currently, intermediate states can derail renewable generation and its multi-state transmission to demand centers • Need to incent the intermediate states to gain from transmission, not just producer and end user Copyright© 2010 Ronald L. Miller. Material can be shared or copied with attribution to the copyright holder. http://www.linkedin.com/pub/ron-miller-p-e/4/842/580 28
    • Summary, cont’d. • To harvest best resources with economies of scale, national extra-high voltage transmission system similar to interstate highway & natural gas pipeline system is needed • Combine different RE technologies whose energy production profiles are complementary to improve transmission asset utilization and project rate of return Copyright© 2010 Ronald L. Miller. Material can be shared or copied with attribution to the copyright holder. http://www.linkedin.com/pub/ron-miller-p-e/4/842/580 29
