Thanks to all of you for what you do, we learned through COVID that we are much more interconnected than we ever dreamed. We need each other more than we want to admit. Keeping the lights on is more than just lineman, substations, and generating plants. It takes all of us and all of you. Congratulations on your awards and an “attaboy” to Emerald for taking the time to do so.
