Nuclear is responsible for operating the Point Lepreau Generating Station. Here, we safely and reliably generate electricity for the wholesale market. Commissioned in 1983, the 660 MW unit, was the first CANDU-6 to begin commercial operation.

Nuclear safety is the primary focus of station activities. CANDU is an established Canadian technology with an excellent nuclear safety record, and Point Lepreau is a safe working environment. The station has exceeded one million person-hours without a lost-time accident – three times.
