The idea that wildfires are seasonal is fading, with fires occurring during summer, fall and now even winter months. Urban damage and destruction from fires are no longer an occasional matter, but rather are recurring events that demand more attention from utilities.
It all starts with a basic understanding of electric grids. Specifically, that existing distribution grid architecture is ubiquitously deployed throughout local communities. Typically, the density of transformers within a localized distribution grid is commensurate with the density of people, businesses and institutions in the community. Populous areas are precisely where increased wildfire protection is needed.
Each overhead transformer presents a unique opportunity for improved public safety, by capitalizing on the location, height and density of existing transformer fleets. Specifically, existing overhead distribution transformer fleets present an opportunity to establish a community-wide wildfire sensor network — an emerging solution to help utilities improve public safety protection.
Wildfire Sensor Network
While no single solution is going to solve all wildfire woes, it is important to note that multiple solutions operating synergistically can deliver tremendous value. Increased vegetation management efforts, more frequent electric grid inspections and occasional public safety power shutoff (PSPS) actions have been implemented. However, it is painfully evident every year that more robust solutions are necessary when it comes to increasing public safety protection and reducing wildfire destruction. One emerging solution allows utilities to use their existing grid architecture.
By leveraging the height, location and density of existing overhead transformers, field sensors can be used to create an overarching community-wide canopy that monitors certain atmospheric and environmental conditions (i.e., outdoor smoke/gas, ground-level fire, ambient temperature and humidity). One such example, Gridwide Fire-Spy, provides always-on, outdoor wildfire sensors that can be deployed quickly on overhead transformers to mitigate wildfires.
Using cellular communications, the Gridwide Fire-Spy sensors simultaneously deliver early detection of wildfires, automated alerts, ongoing situational awareness and certain wildfire prevention capability. By leveraging existing grid infrastructure, this emerging solution not only adds a protection level that benefits the community and local economy, stakeholders and the environment but also reduces future wildfire cost impacts.
Ask any first responder what the key is to fighting wildfires: Beyond the obvious response of prevention comes the response of timely notification. In other words, time is key, time is money, time is life. Time is everything when it comes to fighting wildfires. A timely notification typically is the difference maker between thwarting a disaster
and battling one (and then paying for it). Early detection and automated alerts are instrumental to getting timely notification of a potential event.
With an emerging solution like the community-wide outdoor wildfire monitoring canopy, utilities can capitalize on what they already have at their disposal — a wildfire mitigation framework that leverages their existing transformer fleet for proactive community-wide protection.
Wildfire Season
The seasonality of wildfires is diminishing, as fires have become a perennial occurrence. Recent history has proven ongoing vigilance is necessary and more robust wildfire mitigation solutions are needed. Following are some notable wildfire impacts that have occurred during different times of the year over the last five years:
This abbreviated list of wildfire-inflicted disasters is merely the tip of the data iceberg when it comes to wildfire incidents, acres burned, structures destroyed, fatalities and injuries incurred, and related costs. It is now apparent the so-called wildfire season is expanding. In California, the wildfire season increased by upwards of 75 days in 2021, according to the California Department of Forestry and Fire Protection (CAL FIRE). Then came the Colorado Fire on Dec. 30, 2021. Given the ongoing increases in annual ambient temperature, expanded and extended drought conditions, and more frequent windstorms, it seems there is no longer a conveniently definable wildfire season.
Related Costs
Estimated wildfire costs in the U.S. in 2020 were US$ 114.2 billion. Annually, wildfire destruction represents billions of dollars in losses. Think about that: Billions of dollars every year are required from somewhere to pay for wildfire aftermaths. A single fire, the 2018 Camp Fire in Paradise, California, resulted in an estimated US$ 25.5 billion in losses. Wildfire suppression costs alone require hundreds of millions and sometimes even billions of dollars each year. Oregon’s suppression costs topped US$ 354 million in 2020. The Camp Fire incident exceeded US$ 150 million in suppression costs.
In addition, tens of thousands of firefighters and first responders are put at risk each year to address ongoing wildfires. For example, approximately 5600 firefighters were dispatched to the 2018 Camp Fire event.
Yet, while post-event insurance monies, legal settlement monies, and local, state and federal funding support are helpful, nothing truly replaces what is lost because of wildfires — whether it be human loss, material and property loss, or environmental loss. However, money is always an important element in the wildfire equation because annual wildfire costs are staggering. Local, state, and federal governments have been burdened substantially by the combination of ongoing wildfire suppression costs and post-event rehabilitation costs. In some cases, wildfire costs and collateral impacts on local economies have demonstrated the potential to severely impact local, state and even federal budgets. Notably, the economic impact loss and related tax revenue loss that ensues from wildfires.
All these recurring wildfire-induced cost impacts result in tax increases, insurance premium increases, cost of material increases and more. These increases must be factored into the overall costs associated with wildfires. Although, regardless of how helpful it is to receive post-event funds from any source, no amount of money truly restores people’s lives, their homes and the environment following a disastrous event. It is clear additional steps need to be taken to decrease wildfire impacts and try to prevent more wildfires from occurring. Utilities must reduce the size, scope and frequency of these events.
GHG Emissions
Ongoing messaging from federal and state authorities, academia, environmentalists and climate activists indicates greenhouse gas (GHG) emissions can be curtailed. From coal plant closures to coal-generated electricity plant decommissioning, to electric vehicles adoption, etc., steps are being taken to reduce GHG emissions, typically in the form of carbon dioxide. Increasing average ambient temperatures, prolonged droughts, increased windstorms and wildfires are now commonly attributed to climate change conditions.
Using this environmental understanding as a foundation, it is clear wildfire mitigation must be actively addressed at more serious levels. Annually, wildfires churn out massive levels of carbon dioxide into the atmosphere. Plumes of smoke and ash sometimes travel hundreds of miles and even enter the jet stream to travel greater distances. Think about it: Almost every year, wildfires cause as much GHG emissions as nearly one-fifth to one-fourth of the U.S. auto fleet’s annual GHG emissions.
Thinking Bigger
Now, utilities can start thinking bigger when it comes to their role in wildfire mitigation and public safety gains. Whether it be due to massive annual cost burdens, environmental damage, GHG emissions impacts, and loss of life and injuries associated with these events, all stakeholders including utility operators must now apply perpetual focus. Year after year, wildfire events have proven to us that “worst-case scenarios” just keep coming; they are becoming commonplace. And, we now see that our wildfire season has become a full-time threat (i.e., nearly every month is now registering wildfire occurrences). In turn, utility operators need our ongoing support to adopt emerging technologies to broaden our public safety protection efforts. The grid provides a unique solution opportunity.
Once upon a time, people did not wear seat belts. Now, virtually everyone does. Once upon a time, few people had smoke detectors in their homes. Now, virtually everyone does. At present, community-wide outdoor wildfire monitoring canopies are merely an emerging solution. However, in due time, outdoor wildfire mitigation sensor solutions will become commonplace for utilities. Perhaps the real question is this: How much cost burden, environmental damage and loss of life will justify this proactive approach?
As utilities contemplate where and when to deploy community-wide wildfire monitoring solutions, they also must consider the mental anguish and anxieties that ongoing wildfire risks present. Given the frequency and magnitude of wildfire events recorded to date, surely utilities have seen enough. Now is the time to begin the proactive process of further enhancing wildfire mitigation and public safety efforts by leveraging existing distribution grid assets to get there.
