Electric Interconnections<br />
SCE&G purchases all of the electric generation of GENCO’s Williams Station under a Unit Power Sales Agreement which<br />
has been approved by FERC. Williams Station has a net generating capacity (summer rating) of 605 MW.<br />
SCE&G’s transmission system, which extends over a large part of the central, southern and southwestern portions of South<br />
Carolina, interconnects with Duke Energy Carolinas, Progress Energy Carolinas, Santee Cooper, Georgia Power Company,<br />
Oglethorpe Power <strong>Corporation</strong> and the Southeastern Power Administration’s Clarks Hill (Thurmond) Project. SCE&G, Duke Energy<br />
Carolinas, Progress Energy Carolinas, Santee Cooper, Dominion Virginia Power and ALCOA Power Generating, Inc. (Yadkin<br />
Division), are members of VACAR, one of several geographic divisions within the SERC. SERC is one of eight regional entities with<br />
delegated authority from NERC for the purpose of proposing and enforcing reliability standards approved by FERC. SERC is divided<br />
geographically into five diverse sub-regions that are identified as Central, Delta, Gateway, Southeastern and VACAR. The regional<br />
entities and all members of NERC work to safeguard the reliability of the bulk power systems throughout North America. For a<br />
discussion of the impact certain legislative and regulatory initiatives may have on SCE&G’s transmission system, see Electric<br />
Operations within the Overview section of Management’s Discussion and Analysis of Financial Condition and Results of Operations<br />
for <strong>SCANA</strong> and SCE&G.<br />

Six of the seven fossil fuel-fired plants use coal. Unit trains and, in some cases, trucks and barges deliver coal to these plants.<br />
Coal is obtained through long-term supply contracts and spot market purchases. Long-term contracts exist with suppliers<br />
located in eastern Kentucky, Tennessee and West Virginia. These contracts provide for approximately 3.5 million tons annually,<br />
which is substantially all expected coal purchases for 2012. Sulfur restrictions on the contract coal range from 1% to 2%. These<br />
contracts expire at various times through 2014. Spot market purchases are expected to continue when needed or when prices are<br />
believed to be favorable.<br />
<strong>SCANA</strong> and SCE&G believe that SCE&G’s operations comply with all applicable regulations relating to the discharge of<br />
sulfur dioxide and nitrogen oxide. See additional discussion at Environmental Matters in Management’s Discussion and Analysis of<br />
Financial Condition and Results of Operations for <strong>SCANA</strong> and SCE&G.<br />
