‘Tis the Season to Stay Clear, Stay Safe

Winter water poses additional dangers

Toronto, ON – Winter holidays can be an excellent time for outdoor activities – but please ensure you and yours stay clear of hydroelectric facilities when doing so.

Operation of hydro dams can affect both water flow and ice conditions, making it absolutely critical to follow signage and barriers around Ontario Power Generation’s (OPG’s) hydroelectric facilities. Even in very cold conditions, ice in these areas can be thinner than expected and less consistent, due to the way water flows around dams.

"While you take part in outdoor activities this holiday season, please respect signs and barriers around hydroelectric facilities. Our best wishes for the holiday season include a reminder to stay clear and stay safe."

Nicolle Butcher, OPG SVP of Renewable Generation and Power Marketing

For more information about water safety, please visit: dev.opg.com/watersafety.

Quick facts

OPG operates 66 hydroelectric stations and 240 dams on 24 Ontario river systems.
Many of these facilities are remote controlled, meaning there’s no one there to warn you of imminently changing, potentially dangerous conditions.
For your safety, do not snowmobile, ski, ice-fish or participate in any other activity around dams and generating stations.
Drowning doesn’t just happen in the summer: according to the Lifesaving Society, approximately 35 per cent of drownings in Canada occur from October to April when most people have no intention of going into the water.

Quote

“Water safety is a year-round concern,” said Nicolle Butcher, OPG Senior Vice President of Renewable Generation and Power Marketing. “While you take part in outdoor activities this holiday season, please respect signs and barriers around hydroelectric facilities. Our best wishes for the holiday season include a reminder to stay clear and stay safe.”

About OPG

As a global climate change leader and the largest, most diverse electricity generator in the province, OPG and its family of companies are helping lead the charge to a post-carbon economy.

Au cours de la saison hivernale, restez à l’écart, c’est plus sûr

En hiver, les cours d’eau présentent des dangers supplémentaires

Toronto, ON – Les vacances d’hiver représentent une excellente période pour pratiquer des activités de plein air. Mais assurez-vous de demeurer à l’écart des installations hydroélectriques.

L’exploitation des barrages hydroélectriques peut avoir une incidence à la fois sur le débit d’eau et les conditions de la glace. C’est pourquoi il est primordial de respecter les panneaux et les barrières autour des installations hydroélectriques d’Ontario Power Generation (OPG). Même par grands froids, la glace dans ces secteurs peut être plus mince que prévu et moins uniforme, en raison de la façon dont l’eau circule autour des barrages.

Pour de plus amples renseignements sur la sécurité aquatique, veuillez consulter le site Web suivant : dev.opg.com/watersafety.

Faits en bref

OPG exploite 66 centrales hydroélectriques et 240 barrages sur 24 rivières de l’Ontario.
Bon nombre de ces installations sont contrôlées à distance, ce qui signifie qu’il n’y a personne sur place pour vous avertir des conditions potentiellement dangereuses qui changent de façon imminente.
Pour votre sécurité, ne pratiquez pas la motoneige, le ski, la pêche sur glace ou toute autre activité près des barrages et des centrales hydroélectriques.
Selon la Société de sauvetage de l’Ontario, les noyades ne surviennent pas uniquement en été : environ 35 % des noyades au Canada ont lieu d’octobre à avril, alors que la plupart des gens n’ont pas l’intention de se retrouver dans l’eau.

Citation

« La sécurité aquatique est une préoccupation tout au long de l’année », a déclaré Nicolle Butcher, vice-présidente principale, Production d’énergie renouvelable et marketing d’énergie à OPG. Au moment de pratiquer des activités de plein air pendant la période des Fêtes, nous vous prions de respecter les panneaux et les barrières autour des installations hydroélectriques. Nous vous offrons nos meilleurs vœux de bonheur en cette période de célébrations, et n’oubliez pas de rester plus loin, c’est plus sûr.

À propos de OPG

En tant que leader mondial de la lutte contre les changements climatiques et le plus important et diversifié producteur d’électricité de la province, OPG et sa famille d’entreprises contribuent à montrer la voie vers une économie à faibles émissions de carbone.
