As of late Sunday, more than 80,000 customers were still without power in Louisville. But utility crews made progress thanks to warmer weather. And no new reports of downed power lines came in Sunday, which also helped lighten workers’ loads. While LG&E spokesman Chris Hermann says Louisville’s power infrastructure suffered heavy damage, repairs and equipment replacements will shore up electricity delivery in the future.“Because we’ll be able to rebuild those transmission sites, those towers, those lines, and actually reliability goes up from that point on," says Hermann.Hermann says western Kentucky suffered extreme damage to its transmission capability. Utility crews from out of state are still assisting here. Local officials also warn people without power not to use generators or grills indoors for heat because of the risk of carbon monoxide poisoning.
