Entergy pointed to investments made at Grand Gulf over the past year and described more recent problems with its operations, but didn't address past issues brought up in the complaint. In a statement, the company said: "In late 2020, the plant experienced operational issues related to that upgrade, including unplanned shutdowns and time spent off the grid. We've worked to identify the related issues, implemented a maintenance outage and conducted additional training for our team." Entergy generates and distributes electric power to customers in Arkansas, Louisiana, Mississippi and Texas.
