Some AM stations went silent last week as SDG&E cut power to San Diego County zones they deemed vulnerable to winds during extreme fire season. According to Darnell Forde, Salem Media Group Chief Engineer, KCBQ 1170 kHz and Family Radio’s KECR 910 kHz at their shared site in Lakeside lost power December 2nd, 2020 at 10:13 PM and it did not return until 5:02 AM on December 4th, some 31 hours later. They do not have generator backup power available.
KPRZ 1210 kHz south of San Marcos lost power briefly the same night, but an emergency generator ran until the utility restored power at 9:28 AM on December 4th.
Darnell said Lakeside and the area around Elfin Forest where the KPRZ transmitter is located experienced high winds during those outages.
San Diego Gas & Electric has adopted a policy of cutting power during wind storms since several fires in California were blamed on power lines arcing.
