NL Hydro continues power watch to Friday, Avalon customers may be asked to conserve

A power watch issued for Newfoundland and Labrador Hydro customers on the Avalon Wednesday morning will stay in effect until Friday.

One of three generating units at theHolyroodplant was taken offline for repair early Wednesday morning.

Dawn Dalley, Nalcor Energy'svice-president of corporate relations and customerservices,says that's not an unusual event this time of year.

"It's very technical, but it looks like a boiler tube leak," she told CBC Radio's St. John's Morning Show.

Crews, she said, are working to assess the damage and should know in the coming days how long repairswill take.

With cold temperatures forecasted again for Friday, Hydro said it will continue a system watch until then and advise customers of any changes.

Dalley saidthe incident washandled differently "this time around" compared to outages two years agoas the Crown corporationput "additional generation online early."

"We've had additional generation on last night, our gas turbines are up and running just at the ready in case something does happen that we'll be able to respond quickly," she said.

Lessons learned from #DarkNL

Dalley said after the rolling blackouts and other power setbacks ofrecent years, the corporationhas learned customers want to be warned ahead of time.

"What it saysis we're watching the system closely, load is high and we want you to know that we're monitoring it closely. A bit like if you were driving your car and your engine light came on," she said.

Dalley said power generation across the islandis fine.

"This really is just an issue for the Avalon Peninsula. It's the nature of how our system is. We have a lot of people on the Avalon, lots of electricity usage on the Avalon."

Scale back

The utility is working closely with Newfoundland Power and Dalley said, if the situation worsens, a power warning will be issued.

Dalley said heat and hot water are the biggest drains on the system.

Customers were asked to turn down their heat by a couple of degrees and to turn off any unnecessary appliances Wednesday morning.

By afternoon, Hydro no longer requested customers conserveelectricity, but said it's always a good idea to "be prepared to conservein the event of a status change."

Hydro forecasts that peak times of demand on the system arebetween 7 and 9 a.m., and 5 and 7 p.m.

Cold weather is expected again on Friday.Hydro said it will continue monitoring the system and will notify customers of any changes.
