Dozens of San Diego County neighborhoods are scheduled to lose power for stretches of several hours between Wednesday and Friday while crews carry out repairs and system upgrades, and for households that run oxygen concentrators, CPAP machines, powered wheelchairs, or refrigerated medicine, that is a medical planning problem rather than an inconvenience.
San Diego Gas and Electric's outage detail list shows planned work affecting Ocean Beach, Lemon Grove, San Ysidro, La Jolla, Escondido, Valley Center, Ramona, Clairemont, City Heights, Oceanside, Fallbrook, El Cajon and other communities across the county. Most daytime windows run between about three and eight hours, a few are much shorter, one runs most of a working day, and several are scheduled overnight.
The health consequences of a planned outage are largely preventable with a day or two of notice, which is exactly what customers have right now. The households that get hurt are usually the ones that did not know the outage was coming or did not realize a device or a medication depended on the grid.
Neighborhoods on the Schedule Between Wednesday and Friday
The scheduled work is spread widely rather than concentrated in one area. Ocean Beach, Midway and Lindbergh Field are listed for an outage running from morning to mid-afternoon Wednesday, as are Lemon Grove and the Nestor, San Ysidro and Otay Mesa area. East Ramona appears on all three days with separate plans.
Thursday's list includes La Jolla and La Jolla Shores, Valley Center and Rincon, City Heights and Chollas Creek, Blossom Valley, northeast Escondido, Oceanside, and the Dehesa and Alpine area. Friday brings work in Clairemont and Bay Park, Torrey Pines and University City, Mission Bay and Pacific Beach, and the Dulzura, Potrero and Campo corridor.
Several plans run overnight rather than during business hours, including North City West and Torrey Pines, Escondido, Rancho Peñasquitos and Rancho Bernardo, El Cajon, and West San Marcos. One plan covering Sorrento, Mira Mesa, and Scripps Ranch carries an extended restoration window running into the following week.
Restoration times are estimates. The utility says planned outage details appear on its outage map up to three days before the work is scheduled, and each plan is listed with a six digit plan number. Notifications sent to affected customers include the outage dates, the reason and estimated restoration times, and the utility notes that a scheduled outage can begin as early as midnight on the listed day.
Powered Medical Devices Need a Plan Before the Lights Go Out
The equipment most likely to be affected in an ordinary household includes oxygen concentrators, home ventilators, CPAP and BiPAP machines, nebulizers, powered wheelchairs and scooters, feeding pumps, home dialysis equipment, suction machines and electric hospital beds.
The utility's own guidance is direct on this point. It tells customers who rely on uninterrupted power for medical equipment that a backup plan is essential, because continuous service cannot be guaranteed. In practice, that means knowing device battery run time, having a charged backup battery, and knowing where to go if the outage runs longer than the battery does. The utility also advises working with the hospital or durable medical equipment company that supplied the device, since some suppliers provide additional equipment during emergencies.
Oxygen users should confirm they have a backup cylinder and know how to switch to it. CPAP users can generally skip a single night without harm but should ask their clinician if they have significant cardiac or respiratory disease. Powered wheelchair users should charge fully the night before rather than during the outage window.
Generators solve the problem and create a new one. Carbon monoxide poisoning from portable generators run in garages or other enclosed spaces kills people every year in outage situations. The utility's generator safety guidance says a generator should never run inside a home, garage, or other enclosed building, and asks customers to call and notify the company before using one, because an improperly connected generator can endanger line workers.
Insulin and Other Refrigerated Medicines in a Warm Kitchen
Refrigerated medications are the quieter risk. Insulin, some injectable biologics, certain eye drops, several fertility medications and some antibiotics carry temperature requirements, and a long outage on a warm September day can push a refrigerator out of range.
The practical answer is to keep the refrigerator door closed. The utility notes that an unopened refrigerator can hold food cold for several hours depending on outside temperature, and recommends placing blocks of ice inside to extend that window. Opening the door to check on the medicine is the most common way people ruin it.
Do not guess about whether a specific medication is still usable. Tolerance for time out of refrigeration varies substantially by product and by manufacturer, and a pharmacist can look up the exact figure for a specific insulin or biologic in minutes. Do not discard a costly prescription without asking first, and do not keep using one that a pharmacist advises against.
Food safety runs on similar but separate rules. The utility's planned outage guidance advises that perishable foods should not sit above 40 degrees Fahrenheit for more than two hours, and that items should be moved to a cooler with ice for outages longer than that.
Medical Baseline Enrollment and Free Local Resources
Households that depend on electricity for medical reasons can apply to the utility's Medical Baseline Allowance Program, which provides qualifying customers with an additional monthly allowance of electricity and flags the account so the household is identified as having a medical need. Enrollment requires certification from a licensed medical provider.
It is worth pursuing now rather than during the next emergency, since the benefit only helps if the account is already flagged. Renters and people in multi-unit buildings qualify on the same terms as homeowners. The utility also runs a separate survey form for customers who use an electronic medical device for health, safety, or independence.
Anyone whose service is affected can call the utility's customer line at 1-800-411-7343 for questions about a specific plan number or to report a generator. During hot weather, the utility directs customers to local Cool Zone locations, which offer a place to wait out an afternoon outage for people who cannot tolerate heat. General power outage safety advice covers lighting, phones, and appliance protection.
The schedule will change. Individual plans get delayed, added, or completed early, and unplanned outages from equipment damage and weather have also been reported across the county this week. Readers who rely on power for health reasons should check their own address against the current list rather than relying on any published summary, including this one.
Key Questions Answered
Which San Diego areas are affected? Planned work is listed for Ocean Beach, Lemon Grove, San Ysidro, La Jolla, Escondido, Valley Center, Ramona, Clairemont, City Heights, Oceanside, Fallbrook, El Cajon, and other communities.
How long will the outages last? Most daytime windows run roughly three to eight hours, with several scheduled overnight and one plan carrying an extended window into the following week.
How can someone confirm whether their address is affected? Check the utility's outage detail list or outage map, where each planned outage is listed with a six digit plan number.
What should oxygen and ventilator users do? Confirm backup battery charge and cylinder supply in advance, and know where to go if the outage outlasts the battery.
Is refrigerated medicine ruined by an outage? Not necessarily. Keep the door closed, then ask a pharmacist about the specific product before discarding or continuing to use it.
Is a generator a safe solution? Only when run outside and well away from enclosed spaces. The utility also asks customers to notify it before running one.
What is the Medical Baseline program? A utility program giving qualifying customers who depend on electricity for medical needs an additional monthly electricity allowance, with provider certification required.
