The Electric Reliability Council of Texas says extreme cold temperatures are forecast statewide early next week. The state's electric grid operator issued a weather watch on Wednesday concerning the arctic front that's on its way. Little or no precipitation is expected, so the system isn't a winter storm. ERCOT's advisory says the three-day cold spell could result in "higher electrical demand" and "the potential for lower reserves," grid conditions are expected to be normal. The advisory doesn't direct Texans to conserve energy.
