The Nashville Electric Service (NES) has implemented an "enhanced" outage map following the historic winter storm in late January, which left over 230,000 customers without power for several days. The company has also launched an independent investigation into its response to the outages and has made significant changes to its power outage tool. The updated outage tool has been revamped to make it easier for customers to track outages, and has expanded capacity for more customers to report power outages on high-demand days. Future changes will include restoration timelines and power estimates.
