Diversity of Coal Transportation Modes Purchases

Actions taken to improve Southern’s Coal Supply Position  Increased diversification of supply sources as more Colorado, Utah, and Illinois Basin coals have been purchased for various plants  Test burns of Illinois Basin coals at some of the system’s non- scrubbed plants  Feasibility study of PRB conversions  Reviewing opportunities to blend PRB or Illinois Basin coal at various plants  Developing 3 million annual ton rail to barge loading capacity at Alabama State Docks (ASD) in Mobile, AL  Maintaining increased railcar fleet reserves to allow some non- traditional supply moves as constraints emerge  Constructed Gorgas transloader to support truck coal sourcing

Strategy and Coal Procurement Process Provide a reliable, low cost, environmentally acceptable fuel supply

 Evaluate the entire value chain of fuel, transportation, operations and allowances to achieve the lowest reasonable total cost while meeting reliability and environmental requirements.  Five key risks identified and strategies to mitigate: Volume:  Flexibility needed to adjust to burn fluctuations  Procure to guideline percentages based on the generation nature of the unit Price:  Goal to be at market while mitigating significant swings  Typically 3 to 5 year contracts Supply:  Seek diversity of supply regions and transportation modes  Blending coal opportunities Reliability:  Creditworthiness  Replacement cost language Environmental:  Incorporate non-negotiable Environmental Force Majeure language in ALL contracts Coal Procurement Strategy

Coal Procurement Process Execute Contract(s) Paperwork (FAACS, Comtrac, P.O.’ s, etc.) Paperwork (FAACS, Comtrac, P.O.’ s, etc.) Negotiate Terms and Conditions Short List NPV Analysis Long Term (Mail) Strategic Plan Projected Need Internet RFP Posting Spot (CIBS) Initial Screening Railcar Team OPCOs/ Plants Logistics Admin Field Reps Interaction/Feedback/Inputs Execute Confirmation (LOI) Treasury Delivered cost evaluation

Note: Assumes 12,000 btu/lb coal; 1% sulfur at $300/ton of SO 2 for Plant X Subtotal before Sulfur= $100.65/ton or $4.19 per MMBtu Total with Sulfur= $106.65/ton or $4.44 per MMBtu Total Cost Example by Component

Evaluation of NO x  Background: – Due to requirements of the Clean Air Amendments of 1990, all OPCo’s now include NOx in the delivered cost equation – NOx predictor model (EPRI/SoCo) includes all Southern Company coal units  Process: – Enter mine specific ultimate analysis into NOx predictor model – Evaluate to applicable unit(s)  Result: – The unit specific result is reported in lbs/mmbtu – This result is converted to a $/mmbtu result by multiplying by $/ton NOx cost Example: Model result for Mine A to Plant X= lbs/mmbtu NO x allowance cost = $2,880/ton lbs/mmbtu x $2,880/ton= $0.576/mmbtu 2,000 lbs/ton

Total Cost Example by Component (w/ NO x ) Notes: Assumes 12,000 btu/lb coal; 1% sulfur at $300/ton of SO 2 and $2,880/ton for NO x for Plant X and assumes Plant X has no NO x controls. Total with Sulfur and NO x = $120.44/ton or $5.02 per MMBtu Subtotal with Sulfur= $106.65/ton or $4.44 per MMBtu

2009 Southern Company Outlook  Decrease in coal burn – Natural gas – Economy – Environmental costs  Increase in Inventory – Strategically optimize system inventories to account for any overage – Carrying cost vs. avoided cost  Projected Purchases – 2009 – forward

Future Generation Supply  Nuclear – Vogtle 3 & 4 – Georgia Power Company –2,200 MW - ownership share is 45.7% –Certification ruling in March/April 2009, on-line in 2016 and 2017  Gas CC – Plant McDonough conversion – Georgia Power Company –500MW coal to 3 gas/oil CC units at 840MW each –Completed in 2012  IGCC – Kemper County – Mississippi Power Company –582 MW lignite mine mouth coal gasification plant –Carbon capture and sequestration capabilities –Certification ruling in late 2009, on-line in November 2013  Biomass – Plant Mitchell conversion – Georgia Power Company –96 MW – one of largest biomass plants in the country –Certification ruling in March/April 2009, on-line in June 2012 –Lower fuel and operating costs when compared to continued operation using coal  Plentiful supply all within 100 miles, low transportation costs  Biomass – 5% co-firing being studied at many other system plants

Conclusion  2009 will continue to present challenges  Environmental costs will continue to have a negative impact on coal burn  No projected additional coal purchases this year  2010 and beyond there are projected needs  Southern Company is continuing to investigate new generation sources
