Point Lepreau is producing electricity.
NB Power says the generating station began producing electricity yesterday for the first time since 2008.
The plant has been out of service since March 2008 for a refurbishment meant to extend the life of the reactor by 25 years.
The project is about three years behind schedule and $1 billion over the original $1.4-billion budget.
NB Power has said the reactor is expected to return to full service sometime this fall.
