Wildfires threaten power lines; DWP asks residents to conserve [Updated]

Firefight

With wildfires near Palmdale threatening power lines, the L.A. Department of Water and Power asked residents Friday to reduce their energy usage wherever possible.

“We’re asking people to help care for our infrastructure while this fire is burning, as we wait for the potential threat to diminish,” said Brooks Baker, a spokesman for the agency.

Officials said the agency minimized power imports Friday on a transmission line that passes through the Leona Valley -- where the Crown fire is burning -- and began generating power at in-basin power plants to deliver energy to the city.

“At this time, the power system is functioning normally, and there are no fire-related outages,” Baker said.

[Updated at 1:29 p.m.: With multiple transmission and distribution lines threatened, Edison officials said 21 customers were without service in Lancaster, most of them located south of Elizabeth Lake Road.

Those customers had been without power since about 4:20 p.m. Thursday, and it was unclear when service would be restored, officials said in a statement.

The California Independent System Operator, which manages the state's electrical grid, has brought additional generation resources on line in case Edison loses transmission lines.]

 

Deputy Chief Michael Bryant of the L.A. County Fire Department said both DWP and Edison power lines were threatened, and protecting this “critical infrastructure” was a priority for firefighters battling the blaze.

“These power lines provide the infrastructure for power throughout the state of California,” Bryant said.

By late Friday morning, the Crown fire -- driven by dense fuel, steep slopes and wind -- had consumed around 8,000 acres. Four dwellings and at least half a dozen outbuildings had been destroyed, Bryant said.

How is conserving going to stop the wild fires?

Conserving doesn't stop the wild fires, but it does help minimize the power disruptions that could results from the fire. The fire is threatening lines used to bring power into the city that's been generated elsewhere. If we can't bring that power in, we have to generate it here. If we don't have enough capacity to generate as much power as is being used, there may be disruptions. If people conserve energy while the fire is burning (that is, while we cannot bring in as much energy through those transmission lines) then the chances that there will be more demand for energy than we can produce are lessened and there's less likely to be disruptions to service. Simple enough.

Darn shame other communities have to import their juice from Oxnard....

Paul, the request to conserve electricity has nothing to do with putting out the fires. In simple terms, with the loss of any major power lines, the entire electrical grid is stressed as power demands shift to other sources. Widespread brownouts or even blackouts can occur if the entire system is too greatly burdened. When a transmission line goes down, not all customers lose power, but the ones who don't receive it via a different source.
