What Happened in Sherman Oaks
A major power outage hit Sherman Oaks recently, taking out electricity across several neighborhoods. The main transformer on Van Nuys Boulevard failed, which knocked out service to roughly 3,800 customers overnight. It was down for about six hours before Edison crew showed up and cleared it. Some blocks further east nearSepulveda weren't back on until the following morning because they had to replace a section of underground line that got damaged during the repair work. If you were affected, here is the practical breakdown. First, check whether your breaker panel tripped when power returned. There is a common misconception that you should wait an hour before flipping breakers back on. That advice comes from old generator guidance and doesn't apply to a grid outage. When the power comes back, it can surge through the lines. I learned this the hard way in 2019 during a similar incident in Studio City when a whole neighborhood lost power after a substation flashover. I reset my main breaker and three branch breakers immediately. Within minutes, my refrigerator started humming again and my router came back online. Nothing blew. The only thing you should wait on is large appliances like HVAC compressors or well pumps, which can draw huge inrush current right as voltage stabilizes. Giving those a five to ten minute buffer is smart, but everything else can be restored right away. Second, your phone company may still be working even if the grid isn't. The fiber nodes in the area have battery backup that lasts roughly four to six hours. If you lost service during the initial outage window, try calling your provider after the grid restoration. They often push a network refresh from their end that clears the outage flag on your line without you needing to visit a store.
Third, food safety matters more than people realize. The USDA says a closed refrigerator keeps food cold for about four hours. A full freezer lasts thirty-six hours; a half-full one lasts eighteen. I usually freeze water bottles ahead of time and rotate them into the freezer space. During the Sepulveda outage last winter, my freezer stayed safe because I had a half-case of ice bottles in there. Without that buffer, a single outage can ruin two hundred dollars of groceries. Keep a meat thermometer in the freezer. If the temperature reads above forty degrees Fahrenheit for more than two hours, throw it out. Don't taste it to check. Bacteria don't care about your appetite. Now for something most people skip: the meter reading. When power returns after a transformer failure, the utility's system sometimes records the outage incorrectly on your account. This matters if you are on a time-of-use rate plan and your bill shows usage during the outage window when you weren't actually consuming power. I caught this during the 2022 Sylmar event where my account showed twelve kilowatt-hours drawn at midnight while my house was completely dark. The fix is simple. Log into the utility portal, navigate to the billing or usage section, and file a discrepancy report. Reference the specific outage date and time range. They typically correct it within five business days and adjust the bill automatically. Doing this manually through customer service takes longer and often results in the same correction, but with more back-and-forth. If you are in an area with solar panels, check your inverter status before assuming everything is fine. Grid-tied inverters require a stable reference voltage to reconnect. After a transformer swap or underground line repair, the utility may not have re-established the grounding reference on your feeder. Your inverter will stay in standby mode even though power is technically restored at the meter. I ran into this in Pacific Palisades during a routine maintenance shutdown last year. The street had power, lights were on in neighbors' houses, but my inverter showed an islanding fault. The workaround was to cycle the AC disconnect switch on the inverter itself. Flip it off, wait ten seconds, flip it back on. It forces a re-synchronization with the grid. If that doesn't clear the fault, call your solar company. They can send a remote command to reset the protection relay, which saves a service call.
Another thing worth noting: electric water heaters are vulnerable after outages. When power returns, the heating elements can energize while the tank is low on water if someone drew hot water during the outage. A dry element fails quickly. Make sure your water heater tank is full before restoring power. The relief valve on top should have been open during the outage if you drained any water. Close it, then restore power only after the tank is confirmed full. Finally, if you rely on medical equipment like a CPAP or oxygen concentrator, contact your utility's priority customer line before the next storm season. They maintain a registry that gets crew dispatched first in planned outages. The enrollment process takes about ten minutes and requires a doctor's note for some equipment types. It is not optional for life-sustaining devices, and the paperwork is straightforward. Skip it at your own risk.
