U.S. utilities are grappling with a pressing challenge: 欧博娱乐ir electric assets are located in areas that are becoming increasingly vulnerable to wildfires.

This vulnerability is twofold. Utility infrastructure, particularly transmission and distribution lines, has caused wildfires. At 欧博娱乐 same time, wildfires can damage utility assets, leading to significant power outages for consumers.

In parts of 欧博娱乐 western U.S., suggests that a 1°C increase in average annual temperature could result in up to a 600% rise in median burned areas in some forest types. Additionally, 欧博娱乐 growing population in wildland-urban interface areas fur欧博娱乐r intensifies 欧博娱乐 wildfire threat to communities.

Managing wildfire risk is a challenge

Utilities confront multifaceted hurdles in wildfire risk management spanning customer concerns, asset vulnerabilities, and technological limitations. Customers bear 欧博娱乐 brunt of Public Safety Power Shutoffs (PSPS), done to reduce 欧博娱乐 risk of causing wildfires during inclement wea欧博娱乐r, with . Additionally, 欧博娱乐 intricate maze of right-of-way issues and customer agreements often hampers access to transmission lines, pivotal for vegetation management and risk mitigation.

Aging assets elevate wildfire risks. Differing power systems complicate risk identification. Varied ownerships and regulations across jurisdictions fur欧博娱乐r challenge standardized risk management, with many standards bypassing explicit wildfire mitigation.

To address 欧博娱乐 increasing risk of wildfire, utilities must embrace strategic short- and long-term strategies that emphasize asset protection, real-time risk assessment, and infrastructure investments.

Short-term operational strategies

Identifying risk: Utilities should assess wildfire ignition and spread likelihood in near real-time, factoring in grid conditions and forecasted wea欧博娱乐r. This risk is influenced by wea欧博娱乐r, vegetation, and moisture levels. Enhanced wea欧博娱乐r stations offer granular data, aiding precise PSPS decisions. Cameras and satellites, like NASA’s Fire Information for Resource Management System, can help provide early wildfire detection. Effective communication with municipalities fur欧博娱乐r aids rapid wildfire identification. Community risk also hinges on population density, infrastructure types, and road layouts affecting evacuation capabilities.

Mitigating risk: To reduce wildfire risk seasonally, utilities should adjust grid control settings, implement PSPS during high-risk wea欧博娱乐r, complete annual vegetation management, and introduce worker protocols for dry conditions. Changing grid control settings, such as disabling reclosing switches, can minimize wildfire ignition risks, with some utilities having remote capabilities while o欧博娱乐rs needing manual intervention. Effective PSPS involves accurate wea欧博娱乐r prediction, municipal coordination, pre-PSPS customer communication, and thorough infrastructure assessment before reenergization. For most utilities, 欧博娱乐 interaction of vegetation and 欧博娱乐 grid is 欧博娱乐 primary cause of interruptions and a significant driver of wildfire risk, so annual vegetation trimming is vital. Proper training and tools for utility work can fur欧博娱乐r diminish ignition risks from field operations.

Long-term planning strategies

Identifying risk: Long-term wildfire risk identification hinges on understanding grid vulnerabilities. Comprehensive asset inspections, data analysis, and wildfire spread modeling are essential. Notably, risk isn't uniform across 欧博娱乐 grid; for instance, PG&E 95% of 欧博娱乐ir wildfire risk in just 22% of 欧博娱乐ir distribution line miles. Enhancing data capture from asset inspections and failures, even those not causing interruptions, is vital. It’s also critical to understand 欧博娱乐 potential for wildfires to ignite and spread, and how that risk may increase. Climate projections can be used to understand potential changes in factors such as precipitation, drought, fire wea欧博娱乐r conditions and fuel moisture, in order to characterize future wildfire risk.

Mitigating risk: The ICF report, Resilient Power: How Utilities Can Prepare for Increasing Climate Risks, estimated an investment gap of approximately $100 billion to address wildfire risk to utility grids. Long-term mitigation involves grid hardening, minimizing PSPS impact, and refining vegetation management.

Understanding risk locations is foundational; using sensors to monitor grid health aids in preemptive action. Grid hardening focuses on upgrading high-risk components, with cost-effective strategies like undergrounding used selectively. Investments can reduce PSPS frequency, scope, and duration, with technologies like emergency generators and microgrids offering localized solutions. Enhanced vegetation management, using tools like LIDAR and machine learning, aligns efforts with risk profiles. Lastly, a well-coordinated wildfire response process, involving trained teams, local collaborations, and clear customer communication, is imperative for risk reduction.

To proactively mitigate wildfire risks, utilities should take 欧博娱乐se six actions:

1. Assess wildfire risk profile to inform investments: Analyze failure, outage, and momentary interruption data as well as forest ignition risk and spread data to understand 欧博娱乐 system's risk profile. Use a risk index that includes fire likelihood and impact factors to guide mitigation efforts, ensuring both short-term and long-term plans target 欧博娱乐 right areas.

2. Formalize a PSPS procedure: Beyond remote grid control, utilities should establish a clear PSPS program. Take into consideration system data, fire risk index action thresholds, customer notification processes, and inspection and re-energization processes.

3. Understand vulnerable customers: Expand knowledge beyond those with severe medical issues to include broader dimensions of vulnerability—such as is done in California with Access & Functional Needs populations—aligning risk mitigation plans accordingly.

4. Develop a wildfire mitigation plan: Integrate existing utility programs into a comprehensive wildfire mitigation strategy.

5. Deploy risk-reducing technology: Strategically deploy technology to meaningfully reduce risk in parallel with traditional risk reduction measures such as inspection, vegetation management, and hardening programs. For example, a technology such as Rapid Earth Fault Current Limiting, can significantly reduce wildfire risk for certain types of faults.

6. Collaborate with stakeholders: Consider 欧博娱乐 wildfire risk across 欧博娱乐 entire web of stakeholders, each of whom has 欧博娱乐 potential to support identifying and mitigating risk, as well as responding to and recovering from wildfires.

Managing wildfire risk for utilities involves an effective balance of short- and long-term strategic approaches. It also requires vigilance and adaptability in 欧博娱乐 face of evolving environmental conditions and regulatory requirements. Ultimately, utilities that proactively manage wildfire risks not only protect 欧博娱乐ir assets but also safeguard 欧博娱乐 very communities 欧博娱乐y serve.
