Planned Saturday night power outage in Clarington to knock out power to more than 17,000 homes

A planned power outage Saturday night will knock out power for more than 17,000 Clarington residents as Hydro One replaces ageing equipment to enable a back-up power supply for the Darlington Nuclear Station.

Hydro One will be replacing poles that have reached end of life and installing switches at its Wilson Transmission Station. In order to complete the work a power outage is required.

The outage will take place overnight on April 29 from 11 p.m. to 7 a.m. and affect nearly 13,500 Hydro One customers and approximately 3,600 Elexicon customers, mostly in Bowmanville and Courtice.

“We understand how difficult it is to be without power and thank our customers for their patience as we complete this critical work,” said Hydro One Executive Vice-President (Operations and Customer Experience) Teri French. “Homes and businesses throughout the region rely on us to deliver the power that energizes their lives and communities.”

The company said it has worked to minimize the duration of the outage and schedule it during a time when customers are using the least amount of power. Additional area investments to improve local reliability will also be completed during the outage to eliminate the need for future planned outages.

Affected Hydro One customers have been notified via an automated phone call and can visit Hydro One’s outage map or call 1-888-664-9376 for more information. Affected Elexicon customers have received a notice.

The company is also sharing tips to help customers prepare for the upcoming outage which includes:

  • Making sure appliances, such as the stove, are in the off position.
  • Making sure cellphones and devices are fully charged.
  • Using a battery-powered alarm clock or cellphone to ensure Sunday morning alarms aren’t missed.
  • Keeping refrigerator and freezer doors closed as much as possible and using a cooler with ice for items needed during the planned outage.
  • If water services will be affected at your home, consider filling jugs of water to use for drinking and cooking.

If using a generator, remember to use it in a dry area outdoors away from any open windows, doors and vents. Visit the Electrical Safety Authority at for more tips.
