Power shutoffs during high fire weather now feel like a season of their own in Orinda. If you have wondered which backup power option actually fits your home, budget, and lifestyle, you are not alone. In this guide you will learn how portable generators, standby generators, and battery systems compare, what local permits and utility steps to expect, and how incentives may help. Let’s dive in.

Orinda PSPS risk at a glance

Orinda includes large areas mapped as very high and high fire hazard. Local agencies emphasize defensible space, home hardening, and safe equipment siting to reduce risk. You can review recent fire hazard updates in Contra Costa County reporting for context and planning. Local coverage of updated fire hazard maps explains how widespread the risk is.

PG&E initiates Public Safety Power Shutoffs when wind, humidity, and vegetation conditions raise the risk of power lines igniting wildfires. Alerts can come with limited lead time, and there are special programs for Medical Baseline customers. Learn more on PG&E’s PSPS overview.

Independent reviews of utility data show PSPS outages often last about 1.5 to 2 days and can stretch longer in severe events, so planning for multi‑day resilience is smart. See the duration context from PSE Healthy Energy’s analysis.

Your backup power options

Portable generators

Portable gasoline, diesel, or inverter generators can keep a few key appliances running using extension cords or a manual transfer switch.

• Best for: Short outages and lower upfront cost.
• Advantages: Affordable, quick to purchase, and flexible.
• Trade‑offs: Fuel storage and refueling, noise, emissions, and manual setup. For safety, always run units outdoors and far from doors and windows. The CPSC reminds consumers to install carbon monoxide alarms and never use generators indoors. Review CPSC generator safety guidance.
• Orinda note: Useful for short PSPS events, but fuel access and runtime can become challenges in multi‑day outages.

Standby generators (natural gas or propane)

Standby systems are permanently installed with an automatic transfer switch that senses grid loss and powers all or most of the home.

• Best for: Whole‑home power and longer outages.
• Advantages: Automatic operation, can run major loads, and offer long runtimes on natural gas.
• Trade‑offs: Higher upfront cost, professional installation, ongoing maintenance, and siting rules for noise and clearances. Propane users should plan refills during regional events.
• Orinda note: Expect building and electrical permits, and coordinate siting with local guidelines. County permit steps are outlined in Contra Costa’s permit guidance.

Battery storage (with or without solar)

Home batteries store electricity and can automatically power critical circuits during an outage. Systems can be paired with solar or charged from the grid in advance of a PSPS.

• Best for: Quiet, low‑maintenance backup and daily energy management.
• Advantages: No on‑site fuel, low upkeep, and automatic switchover. When paired with solar, batteries can recharge during daytime for multi‑day resilience. California’s SGIP program offers meaningful rebates for many households. Explore SGIP basics and eligibility.
• Trade‑offs: Upfront cost and runtime limitations depend on system size and your home’s load. Some systems require PG&E interconnection steps, including possible pre‑parallel inspections, before islanding is enabled. See PG&E’s interconnection handbooks for process details.
• Orinda note: Quiet operation can be a neighborhood plus. Plan ahead for interconnection timelines and fire‑safety placement requirements.

Hybrid setups and community options

• Hybrid systems that combine solar, battery, and a standby generator offer flexibility. The battery handles immediate outage switchover and short events, while solar or the generator can recharge the battery for longer PSPS periods.
• Community resilience hubs and microgrid projects in California provide backup for critical facilities and neighborhoods. Keep an eye on regional updates as these models expand.

How much power do you need?

Start by defining what matters most during an outage. List your must‑run items like the refrigerator, lights, Wi‑Fi, phone charging, selected outlets, medical equipment, and any pumps.

• Set a runtime goal: Are you targeting 24 hours, 48 hours, or longer? That choice guides capacity.
• Estimate daily energy use for those circuits. Your utility bills and smart plugs can help. Many homes can ride out a day on a modest critical‑loads plan, while whole‑house needs require more capacity.
• Battery sizing tip: A single home battery unit often stores around 13 to 14 kWh. That can cover essential loads for many hours to roughly a day, but larger homes or whole‑house plans often need multiple units or solar recharging.
• Safe switchover: Use an automatic or manual transfer switch so you do not back‑feed the grid. For islanding batteries, plan the PG&E interconnection paperwork early.

Permits, interconnection, and safety in Orinda

Local approvals and safe installation are just as important as equipment selection.

• Building and electrical permits: Expect permits for generators, solar, and batteries. Start early to accommodate plan review and inspections. Review the County’s process in Contra Costa’s permit guidance.
• Fire‑safety and siting: Battery locations, clearances, and signage must meet code. Coordinate with the Moraga‑Orinda Fire District and follow local hardening and Zone Zero guidance for safer equipment placement. See MOFD defensible space and Zone Zero.
• Utility steps: For batteries that can island, PG&E may require a pre‑parallel inspection and final approval before you are allowed to operate during outages. Plan timelines with your installer using PG&E’s interconnection handbooks.
• Safety first: Never operate a portable generator indoors or near windows and doors. Install and test carbon monoxide alarms. The CPSC outlines key generator safety tips.

Costs and incentives to expect

Budget ranges vary by site, equipment brand, and electrical upgrades.

• Battery systems: Installed costs often range from about $7,000 to $30,000 or more depending on capacity and complexity. See a cost overview here: how much is a solar battery backup.
• Standby generators: Smaller units can be several thousand dollars, while whole‑house natural gas systems with automatic transfer switches and site work commonly land in the mid‑five figures.
• Incentives: California’s SGIP can significantly reduce net cost for qualifying households, especially under equity and resiliency categories. The federal Investment Tax Credit may also apply to residential storage and solar plus storage under current law. Consult your installer and a tax professional for the latest guidance.

A simple action plan

• Check your risk and alerts: Sign up for PG&E notifications and confirm your address details. Review MOFD defensible space guidance and your home’s fire hazard zone.
• Define critical loads: Make a must‑run list and a target runtime so you can compare options apples to apples.
• Get multiple quotes: Ask for itemized proposals that include permitting, PG&E interconnection steps, and commissioning timelines.
• Map the timeline: Permits and utility approvals can add weeks. Start early and plan around seasonal PSPS risk.
• Put safety first: Install CO alarms and follow CPSC guidance for generator use. Confirm your installer’s code compliance and final sign‑offs.
