California fire knocks power lines out temporarily, ISO calls transmission emergency

Houston (Platts)--5 Dec 2017 348 pm EST/2048 GMT


The California Independent System Operator issued a transmission emergency notice for Southern California as a wildfire continues to rip through part the region.

The fire forced four 230-kV lines owned by Southern California Edison out of service, ISO spokesman Steven Greenlee said Tuesday, but the lines have since returned to service.

The notice is effective through midnight PST Tuesday (0800 GMT Wednesday) due to a "local transmission emergency in the Ventura area," according to the ISO.

"A local transmission emergency was declared by the California Independent System Operator due to the loss of critical transmission lines serving the Ventura and Santa Barbara area, and [the ISO] has requested additional generation units to support restoration of power for the impacted area," according to Southern California Edison.

The ISO did not reply immediately to requests for information on how much additional generation was required.

SoCal Ed reported early Tuesday that about 180,000 of its customers in Ventura County and 83,000 customers in Santa Barbara County were without power due to the Thomas Fire, which started Monday night north of Santa Paula.

Around 11 am EST Tuesday that number had dropped to 20,000 customers, according to SoCal Ed.

The size of the Thomas Fire was estimated to be 31,000 acres around 7 am PST Tuesday and was being pushed by strong easterly winds, according to readyventuracounty.org, a partnership between the Ventura County Sheriff's Office of Emergency Services, the US Federal Emergency Management Agency and the Ad Council.

Fixed wing aircraft and helicopters were expected to attack the fire at daybreak.

"Transmission lines will continue to be threatened as the fire continues to burn along the transmission path, possibly causing additional interruptions," according to SoCal Ed.

Real-time power prices in California seemed unaffected by the fire and were in the mid-$20s/MWh around 11:15 am EST.
