3 SCANA CORPORATION Basic Earnings $0.74 (2010) vs. $0.62 (2009) EPS for the Fourth Quarter $2.99 (2010) vs. $2.85 (2009) EPS for the Year

4 SCANA CORPORATION Note (1): In the first quarter of 2010, pursuant to authorization by the Public Service Commission of South Carolina (SCPSC) in connection with its annual review of fuel cost and rates, the Company accelerated the recognition of previously deferred state income tax credits in the amount of $17 million, or 9 cents per share (thereby lowering income tax expense) and recorded an offsetting reduction of 2010’s recovery of fuel costs (electric revenue). Note (2): In January 2010, the SCPSC approved SCE&G’s retroactive adoption of updated, lower depreciation rates for its electric operations effective January 1, 2009. The SCPSC also approved SCE&G’s request that the credit to depreciation expense resulting from the adoption of these rates be applied to reduce recovery of fuel costs (electric revenue). As such, the Company decreased both depreciation expense and electric revenue by $14 million, or 7 cents per share, in the quarter and year ended December 31, 2009. These offsetting decreases had no impact on 2009 net income. Fourth quarter 2009 depreciation expense reflects the entire annual impact of these lower depreciation rates. As a result, depreciation expense is $10 million, or 5 cents per share, lower in the fourth quarter of 2009 compared to the fourth quarter of 2010. Note (3): In May 2010, SCANA entered into an equity forward sales agreement. During periods when the average market price of SCANA’s common stock is above the per share adjusted forward sales price, the Company computes diluted earnings per share giving effect to this dilutive potential common stock utilizing the treasury stock method. 2010 Variances vs. 2009 ^  Quarter Ended Year Ended December 31, 2010 December 31, 2010  * Electric Margin (1)(2) .28 .60 * Natural Gas Margin .00 .15 * Operation & Maintenance Expense (.06) (.15) * Interest Expense (Net of AFUDC) .00 (.09) * Property Taxes .00 (.07) * Depreciation (2) (.08) (.10) * Dilution (.03) (.09) * EIZ State Income Tax Benefit (including interest) .00 (.11) * Other, Net .01 .00 •Total, Basic .12 .14 * Additional Dilution re: potential common stock(3) .00 (.01) •Total, Diluted .12 .13
