Vogtle Unit 3 has safely reached 100 percent power, marking a major milestone towards commercial operation and service for customers. This milestone marks the maximum energy the unit is licensed to produce in the reactor core and is the first time the unit has reached its expected output of approximately 1,100 electric MW, which can power an estimated 500,000 homes and businesses.
In alignment with the testing performed throughout power ascension, testing at the 100 percent power level is focused on the operation of the reactor, plant control systems for the reactor and support systems, and integrated plant operations. Plant performance is monitored at various conditions and data is gathered and evaluated by site engineers. With the unit reaching full power for the first time, other tests must be performed at this power level before the unit is available for reliable dispatch in accordance with its combined operating license.
Once all startup testing is successfully completed and the unit is available for reliable dispatch, Vogtle Unit 3 will enter commercial operation. Unit 3 is projected to be placed in service during June 2023.
