The world's largest nuclear plant is living up to its name.

Bruce Power is now an eight unit nuclear juggernaut, producing electricity for over five million Ontarians.

CEO Duncan Hawthorne is pleased he finally has a full compliment of functioning reactors.

"When I first came here we had four units and they'd all be gone by 2018, now we've got eight units and we want to make sure they're there until 2050," he says.

For the first time in over 20 years, units 1 through 8 at the sprawling site are producing electricity.

It's enough power for over for over a third of Ontario, or over five million households.

Bruce Power has spent $7 billion since taking over in 2001 restarting and refurbishing reactors.

"We've done things that people didn't think you could to these units as we've extended the life, as we've totally rebuilt reactors from the inside out," Duncan adds.

But despite the prosperity it has brought to the region, not everyone is excited about the resurrection of the Bruce site.

Ruth McLean lives nearby and says "So maybe we need to look beyond monetary value and compensations and really address the whole situation at hand," she says.

There's speculation that there are already plans for more reactors at the site.
