According to The Commercial Appeal, TVA's use of gas climbed 70 percent in the fiscal year just ended. At the same time, coal-fired generation declined 30 percent from fiscal 2011. The fiscal years end Sept. 30.
TVA Vice President Bob Dalrymple said the federal utility is trying to achieve a good mix of generation sources, so it can adjust as the market shifts.
The greater use of gas by TVA mirrors a national trend as hydraulic fracturing in drilling releases abundant sources of the fuel.
Nuclear generation also is a major player, accounting for one-third of the power produced by TVA.
