Solar Panels & Home Battery Storage Can Help Mitigate Wildfire Impacts?

What is the Problem?

As extreme weather events are increasingly common and destructive across the U.S., the impact of wildfires on electricity distribution has become a prominent problem.

In Western states, the wildfire season is noticeably longer. Fires that can forever change public lands and destroy private property occur nearly year-round. Plus, these harrowing wildfires are much more frequent and larger over the past few decades.

In upcoming years, such climate change effects are anticipated to continue disrupting our energy systems more often and on a greater scale. For homeowners, businesses and communities, this means longer-lasting power outages, plus service disruptions in critical industrial and technical centers.

During power outages, life as we know it nearly comes to a stop. So, communities are starting to build a more dependable, resilient electrical grid with solar.

How Did We Get Here?

Today’s Grid

We need to rethink our electric grid. We all use it, yet seldom think about it—until it’s not there.

Today’s electric grid is generally energized by large power lines that transmit electricity across long distances from centralized fossil fuel power plants. Greater than 70% of America’s power lines and transformers are over 25 years old.

This aging infrastructure was not built to withstand extreme conditions. And, its vulnerabilities grow with each storm and wildfire. GPS knows there’s a better way to power our lives.

What is the Solution?

Solar Reduces Hazards and Provides Backup Power

Local distributed energy resources (DERs), such as home solar and battery systems, can provide a resilient energy solution in high-risk fire areas currently served by electric lines. The value of DERs is gaining broad community attention and growing government promotion, especially in California due to their recent fire tragedies.

Home solar and battery storage offer reliable energy that keeps households running and safer during wildfire threats. Beyond backup power, DERs reduce the chance of electric sparks from overhead lines potentially resulting in wildfires.

How DERs Support the Grid

Our antiquated electric grid is vulnerable to extreme weather and wildfires, which causes

power outages and further fire hazards. When electricity flows through circuits, power lines

heat up, expand and sag closer to the ground. Too much sag brings circuits near objects or

other circuits potentially resulting in sparks. Circuit sag was a known contributing factor in the

2017 California Fire Siege. Traditionally, to manage wildfire risk, some circuits are entirely

shut down. DERs can take on some network power loads. This keeps electrical circuits within

operating limits, maximizes capacity, and reduces sag. Also, during grid outages, DERs can

directly power impacted homes. Increasing DERs in high-risk locations will help protect

homeowners and assist electric companies in future wildfires.

Consider a community of 500 homes where each uses five kilowatts of power--roughly

equivalent to homes in California’s fire-prone areas. Typically, all these homes are

connected to the grid by a single electricity line creating high stakes for an outage during

hot, dangerous wildfire conditions. However, a network of just 50 to 100 homes with solar

and storage could return the whole community to electrical stability.

Solar and batteries can maintain a safe power flow level on distribution lines, enabling local networks to carry additional power if there are problems on the grid. As an augmenting backup solution, DERs help communities maintain electricity—even if power lines are shut down for prevention by the electric company or due to wildfire destruction. A network of rooftop solar and battery installations reduces strain on energy infrastructure by lowering the amount of electricity pulled from the grid. This reduced power load maintains safer circuit tolerances for a longer time, giving grid operators, line workers, and emergency responders more time to handle outages and wildfire impacts.

Reducing the Chance of Power Outages

With nationwide dependence on today’s traditional grid, cutting electricity transmission is considered a last line of defense because of serious consequences caused by service disruption. In 2018, Pacific Gas and Electric (PG&E) in California faced the difficult decision of when and if to cut off electricity to help ensure community safety during a red flag fire warning. Despite proactively choosing to de-energize power lines in high-risk areas, the massive fire may have been caused by an active line.10 DERS can expand the boundaries of a safe, resilient electrical solution in wildfire regions.

Benefits of an Efficient, Clean Grid

DERs offer a flexible approach to supporting grid load versus unpredictable, traditional poles and wires. This new energy infrastructure would also reduce the use of fossil fuel power generators during emergencies. The bottom line is DERs provide safety, quality and financial gains to both electric companies and consumers.

Join the solar revolution. Homes and communities with rooftop solar and batteries can maintain continuous power during emergency events.  Solar regulation progress will inevitably increase the adoption of DERs as a dependable, sustainable, long-term energy solution.11

Community members and policymakers have the opportunity to fundamentally change grid planning in the West and across the country to benefit future generations. With distributed energy solutions, electricity consumers have greater control of their power supply, peace of mind from power outages, and protection from the ravages of wildfires and extreme climate events.
