  • The slide shows the tremendous increase in environmental laws and regulations over the last 30 years when compared with the previous 50 years.
  • National Capacity Additions Petroleum “Pet” Coke is a by product of petroleum refinery process. (big environmental issues)
  • The Nuclear that was supposed to come in the 70’s came in the 80’s.
  • Technology
  • As we look toward the future Combined Cycle now running at less than 60%. Co2 constraints will cause gas to become base. Combined Cycle can be base, intermediate or peaker depending on price: $ 2 Base $4 Intermediate $6 Peaker
  • We are confident that: There is plenty there We do it well Issues & Risks Financial Conditions of Producer Companies Influence of Gas & Oil pricing on the Coal Markets Risk more comfortable with is Coal Gasification over Pulverized Coal. Rather take technology risk over environmental risk and dual fuel options.
  • Georgia has decent solar radiation / solar energy resources; issues with cost, mismatch of peak solar at 1 pm vs. GPC peak at 4 – 5 pm;
  • Don’t hold your breath for wind energy in Georgia (wait for laugh….); Note that the scale for wind energy doesn’t define the white areas (resource potential below marginal)
  • Maps show potential for wind and solar use in the U.S. – Darkest colors show the best options for wind. The Southeast has almost no opportunity for wind generation -- only potential sites are pristine southern Appalachian ridge tops and off-shore A joint study beginning in 2004 of wind power generation potential off the Georgia coast, conducted by Georgia Tech and Southern Company, concluded that there may be enough wind – in the 15- to 17-mph range – to power an offshore wind farm. What’s Next: Earlier this year Southern Company nominated three sites off Tybee Island for the placement of meteorological towers to collect additional data. Southern Company is currently working with Minerals Management Service of the Department of the Interior to permit installation and operation of meteorological towers. MMS will conduct a public meeting in Savannah on Nov. 12, 2008 as part of a rulemaking process to instruct entities on how to apply and install alternative energy projects on the Outer Continental Shelf. There has been a moratorium on all of these activities in federal water since July 2005 Issues: Current commercial offshore wind turbines are not built to withstand major hurricanes above a Category 3 or a 1-minute sustained wind speed of 124 mph. While available wind data indicates that a wind farm located offshore in Georgia would likely have an adequate wind speed, project costs run approximately 50% – 100% higher than land-based systems. Based on today’s prices for wind turbines, a commercial size 50 MW to 160 MW offshore wind farm could produce electricity at 12.9 to 8.2 cents/kWh respectively. Potential benefits: • Free fuel for the duration of the project with no impacts from increasing fuel prices. • Renewable energy credits and/or potential reduced costs from carbon credits/avoided taxes. • Potential for the creation of a new industry and new job opportunities within Southern Company’s service territory.
  • Don’t hold your breath for wind energy in Georgia (wait for laugh….); Note that the scale for wind energy doesn’t define the white areas (resource potential below marginal)
  • Georgia does have good biomass resource – this is our hope for renewable energy;
  • Appropriate Size for Biomass Relatively small unit Adequate land space for large wood piles Use Much of the Existing Plant
  • Adds Fuel Diversity Utilizes Locally Produced Biomass Fuel 50-75 new jobs in harvesting wood fuel Maximizes the Life and Value of an Existing Resource

    • These cost estimates are illustrative of utility ownership for future generation technologies including capital costs, O&M, and fuel. Costs are projected over the useful life of each generation technology and levelized for comparison purposes. Low and high ranges reflect various assumptions on the uncertain costs of capital, equipment, fuel prices, and the potential costs of carbon legislation.
