When the lights go out in Pinecrest during a Public Safety Power Shutoff, what is your plan for the next 72 hours? If you own a mountain cabin, you know outages can affect more than lights. Wells, heating, refrigeration, and connectivity can all go offline. In this guide, you’ll learn how PSPS events work locally, where to find community support, and how to choose a safe, right‑sized backup power setup for your cabin. Let’s dive in.
PSPS in Pinecrest: What to expect
A Public Safety Power Shutoff is a utility‑initiated outage used to reduce wildfire risk during extreme fire weather. When high winds, low humidity, and dry fuels align, utilities de‑energize targeted lines until conditions improve and inspections are complete. In Tuolumne County, that can include unincorporated mountain communities like Pinecrest.
Expect practical impacts on lighting, refrigeration, well pumps, septic lift stations that use electricity, internet routers, and cell service. Traffic signals and road signage can also be affected. Durations vary by event. Some shutoffs last a few hours, while others extend for multiple days. Plan for at least 48 to 72 hours, and be ready for longer in severe conditions.
For notifications, enroll in PG&E phone, text, and email alerts. Use Tuolumne County emergency alerts for local routing, shelter updates, and safety guidance. State and federal agencies coordinate guidance, but it is smart to rely on multiple local channels for timely updates.
Community resources during outages
PG&E Community Resource Centers
Community Resource Centers offer temporary relief during PSPS events. Typical services include device charging, restrooms, bottled water, and information. Locations, hours, and services vary by event. For Pinecrest residents, CRCs are usually set up in nearby population centers rather than at remote cabin areas. Plan your route, transportation, and pet needs before you rely on a CRC.
County resources and shelters
Tuolumne County’s Office of Emergency Services may open warming or cooling centers and evacuation shelters. Local aid groups often support these efforts. Check county alerts to learn if shelters are open and whether county transport is available.
Stay connected with neighbors
Cell service can be intermittent in mountainous terrain during a PSPS. Build a simple phone tree with neighbors and identify nearby community hubs that may have backup power. Map out gas stations, grocery stores, and visitor centers that typically operate with generators.
Medical and access needs
If you or someone in your home depends on powered medical equipment, enroll in medical baseline or vulnerable customer programs through the utility and county. These registries provide enhanced notifications and help prioritize resources. Apply early, since documentation and lead times may apply.
Choose the right backup power
Before you pick equipment, answer a few questions:
- Which critical loads must run during an outage? Typical essentials include a well pump, refrigerator or freezer, a few lights, a router, and medical devices.
- How long do you expect outages to last? Hours or multiple days?
- What fuel can you reliably access in all seasons? Consider propane, diesel, gasoline, and delivery constraints.
- What is the state of your electrical system? Note panel age and whether your well pump has a dedicated breaker.
- What is your budget, and how important are low noise and low emissions?
Portable inverter generators and solar power stations
These include small gasoline or propane inverter generators and compact battery units often called “solar generators.” They are relatively low cost, quiet, and easy to store. They work well for device charging, LED lights, routers, small refrigerators, and CPAP machines if the continuous rating is adequate.
Limits matter. Run time depends on refueling or recharging. Many units are not powerful enough for well pumps or central heating. For safe home use, connect through a transfer panel rather than stringing cords across rooms.
Conventional portable generators
Open‑frame gasoline or propane generators offer more output, often in the 2 to 8 kW range or higher. They can support a refrigerator, small appliances, and select circuits when sized correctly. They cost less upfront than standby systems, but they are noisier and need careful outdoor placement.
Never run a generator indoors due to carbon monoxide risk. Size for starting surge, not just running watts. Well pumps often need two to three times their running wattage at startup. Use a manual transfer switch or an approved interlock with a generator inlet, and install carbon monoxide monitors in living areas.
Standby generators
Permanently installed standby generators start automatically when utility power fails. They connect through an automatic transfer switch and can be fueled by on‑site propane or natural gas. This setup can support whole‑home or essential loads, including wells and HVAC, with minimal manual effort.
Expect higher total cost that includes equipment, professional installation, permits, and ongoing maintenance. In California, permanent installations require building and electrical permits and must follow county codes and utility safety rules for transfer switching. Plan for fuel storage and delivery access, especially in winter.
Battery storage systems
Home batteries can power essential loads with quiet operation and no on‑site combustion emissions. When paired with solar, they can recharge during daylight and extend autonomy from hours to days depending on sizing and weather.
Batteries alone have finite energy. For multi‑day, heavy‑load events, pair batteries with solar or a generator for recharging. Incentive programs may be available to reduce costs, and utility interconnection approvals apply for grid‑interactive systems. Ask installers to handle required paperwork.
Hybrid setups that work well in cabins
Many remote owners choose a solar plus battery system sized for daily essentials, then add a small standby or portable generator to recharge batteries and cover heavier loads as needed. This reduces fuel use and noise while extending resilience.
Another approach is a standby generator sized for your well pump and HVAC, combined with a small battery for quiet overnight backup of electronics and medical equipment.
Transfer switches and anti‑backfeed safety
Never connect a generator to home wiring without a proper transfer method. A manual or automatic transfer switch, or a utility‑approved interlock, is essential. Backfeeding the grid is dangerous and illegal because it can endanger utility line crews. For battery systems with grid‑interactive inverters, follow utility interconnection rules and approved settings.
Fuel, altitude, and winter notes
Plan for safe, legal fuel storage and confirm supplier access during storms. Propane deliveries can be limited in winter. Gasoline has shelf‑life limits, so use stabilizers and rotate stock. Cold weather reduces battery performance unless systems include thermal management. Generators may need cold‑weather kits and careful choke use. Engine output can de‑rate at higher elevations, so check equipment specifications for performance at mountain altitudes.
Your step‑by‑step PSPS plan
Immediate steps
- Enroll in PG&E PSPS and outage alerts and in Tuolumne County emergency notifications.
- Create a written family plan with emergency contacts, evacuation routes, and a checklist for pets. Stock food, water, and medications for at least 72 hours per person.
- Inventory critical loads. Note model numbers and wattage for your well pump, refrigerator, heating devices, medical gear, and routers.
- Label circuits in your main electrical panel and identify the breaker for your well pump.
Choose and install backup power
- Match technology to your needs, expected outage length, budget, and fuel access.
- Hire licensed contractors for electrical work and generator or battery installations. In California, permits are typically required for permanent systems.
- Coordinate permits with Tuolumne County building and planning departments. Confirm noise and setback rules for generators and follow utility transfer switch requirements.
Safety first
- Install carbon monoxide detectors and test them regularly. Operate generators outdoors, away from windows and vents.
- Store fuel per local fire code in approved containers and keep it away from ignition sources.
- Never backfeed the grid. Use an installed transfer switch or approved interlock and inlet.
- Test systems monthly under load and keep user manuals accessible.
