Additional crews have been coming into Kentucky to help with power restoration efforts.By the end of the day on Thursday, E-On U.S. had hoped to have 18 hundred utility workers in the Louisville area.The crews are mostly coming from the south, where winter storms were not as damaging. E-On Vice President of Energy Delivery Chris Hermann says many of the expected crews have already arrived.“We are therefore moving beyond the hotel rooms that we have acquired and we are beginning to establish options and early plans to set up another staging area, which would be a place for not only feeding and assembling vehicles but also for sleeping, showering and so on," he says.As of Thursday evening, 190 thousand households in the Louisville area were without power. Statewide, more than 600,000 were without power.
