Georgia Power has revised the projected commercial operation dates for Vogtle-3 and -4 a total of four times this year—most recently in October—but some experts are saying that at least one more delay is probable.

Georgia Power yesterday announced that due to 'productivity challenges' and the need for 'additional time for testing and quality assurance,' it has revised the schedule for the Vogtle-3 and -4 nuclear expansion project. The new schedule pushes back the Unit 3 in-service date to the second quarter of 2022 and the Unit 4 date to the first quarter of 2023—a three-to-four-month shift for each unit.
