As of 11 a.m. Monday, power has been restored to most North Georgia EMC customers affected by the snow storm, NGEMC officials said. Several isolated outages may remain. Poor road conditions forced NGEMC to close its Trion business office Monday. However, NGEMC’s business offices in Calhoun, Dalton and Fort Oglethorpe were open for regular business.  At the height of the power outages Sunday night and Monday morning, approximately 600 NGEMC customers were without service in Gordon, Whitfield, Walker, and Chattooga counties. Snow-laden tree limbs falling across power lines were to blame for most of the outages. Crews worked throughout the night and into the morning to restore power as quickly and safely as possible. Tree-cutting crews assisted line crews by working to clear fallen trees across roads and power lines. As mixed precipitation is expected to continue, power outages may continue through the day and night. NGEMC urges extreme caution around fallen trees and power lines. Please do not go near them, but report these immediately to NGEMC or local emergency authorities. Customers without electricity are asked to call their local NGEMC office and use the automated telephone outage reporting system. If outages are widespread, the phone lines may be busy due to a heavy call volume. For customers and media with internet capability, outage information will be posted on the NGEMC web site at www.ngemc.com.   Phone numbers to local NGEMC offices are as follows: Ft. Oglethorpe — (706) 866-2231; Calhoun — (706) 629-3160; Trion — (706) 734-7341; Dalton — (706) 259-9441. NGEMC serves more than 99,000 customers in a seven-county area that includes Catoosa, Chattooga, Floyd, Gordon, Murray, Walker and Whitfield counties.
