[Pickering]: Ontario Power Generation's Pickering Units 4 and 1 are being shut down to begin a short outage to inspect and perform maintenance on a backup electrical distribution network connecting the Pickering A and B stations.

Following recent inspections it was identified that under unusual conditions the performance of some ventilation systems could be reduced. Using a conservative decision-making approach, the Units are being taken off-line while maintenance is completed on the electrical system.

Pickering Units 6 and 8 are operating at or near 100 per cent, delivering over 1,000 MW of electricity to the Ontario electricity grid. Pickering Units 5 and 7 are currently in maintenance outages.

Ontario Power Generation Inc. is an Ontario-based electricity generation company whose principal business is the generation and sale of electricity. Our focus is on the efficient production and sale of electricity from our generation assets, while operating in a safe, open and environmentally responsible manner.
