(WBIR) People cranking up the heat during this bitter cold wave nearly surpassed the Tennessee Valley Authority's winter record for power demand.

TVA's power system reached a preliminary peak power demand of 32,460 megawatts at 9 a.m. Tuesday as the valley's average temperature hit 4 degrees.

This was just 112 megawatts less than TVA's winter record of 32,572 megawatts set back on Jan. 16, 2009 when temperatures averaged 9 degrees. TVA's all-time record is 33,482 megawatts set on Aug. 16, 2007 when temperatures averaged 102 degrees.

TVA said it's thankful for local power companies that have reduced voltage. The electricity provider said it's continuing an in-house conservation effort to reduce electricity use in TVA facilities.
