Disasters are cyclical. The main goal of resiliency is to break the cycle so that the impacts of the next disaster are less severe for people and property. Planning and preparation may seem synonymous, but in this context, planning refers to actions taken years if not decades ahead of time. Consider the way we prioritize our personal health and well-being: while visiting an emergency doctor may be necessary on rare occasions, making preventative care visits to a primary physician lowers the risk of unforeseen health crises. Similarly, safeguarding our critical infrastructure requires a proactive approach centered around prevention. In the planning phase, it’s critical for energy utilities to evaluate weather-related risks, identify vulnerable assets and infrastructure, and determine what can be done ahead of time to mitigate these risks.

New Infrastructure: Design for Resiliency

Although retrofits and repairs are unavoidable in some cases, the ideal strategy is to consider storm resiliency at the time of design and construction – going back as far as the site due diligence and land use planning stages. Before embarking on the development of critical infrastructure such as transmission lines or substations, consider the geographical features, elevations, and water levels of the proposed site. For ongoing construction projects, implement strategies to protect assets and equipment. Flood plains and shorelines are shifting, so assets close to waterways should consider a hydrology study and coastal terrain mapping. Energy utilities may also want to consider a long-term approach to undergrounding their power lines in regions prone to weather-related disruptions; underground lines are less vulnerable to storm damage, falling debris and other environmental factors that cause outages.

Existing Infrastructure: Mitigate Impacts

Aging infrastructure tends to be more at-risk; it’s recommended to perform routine inspections and maintenance of rights-of-way. Develop a comprehensive hazard mitigation plan that includes a thorough risk assessment, operational optimizations, disaster procedure development, personnel training, and technology upgrade recommendations. Procure essential replacement parts and equipment ahead of time to avoid supply chain disruption in future emergencies. Analyze organizational effectiveness to assure staff are trained and available at critical times. Frequently test communications networks used to distribute evacuation warnings and other life-saving information. Many areas also have Local Emergency Planning Commissions (LEPCs) available to advise utilities directly on how to make infrastructure and operations more resilient.

Consider Climate Modeling

As weather events increase in severity, climate risk modeling is another modern planning measure that benefits service providers. Engaging a climate trend analysis consultant can provide valuable insights and help you make informed decisions regarding your service area. Predictive analytics reveal when existing infrastructure and physical assets may be at risk in the near and long term. These insights will help determine what, where and when to prioritize climate risk mitigation measures. Climate risk modeling also helps with making a strong business case for system hardening by enabling a cost-benefit analysis of potential preventative investments. Black & Veatch's eBook on climate modeling for utilities explains how to address key factors including location, weather patterns and climate change data.

The planning phase consists of what an organization does on paper to document physical actions to take. During the preparedness phase, plans are executed to ensure that people, equipment, resources and infrastructure are ready before disaster strikes. Although actions in the preparation phase still are considered preventative measures, the time available to implement them may be more limited than during the planning stage. Regardless of missed planning opportunities, preparation efforts still are more affordable than emergency responses and can optimize outage and recovery timelines.

Focus on Low-Cost, High-Impact Strategies

There are cost-effective, high-impact preparation measures such as deploying sandbags to strategically re-route stormwater in flood-prone areas. Monitor the storm’s progress and adjust the response as necessary. Prepare field crews for potential rapid deployment and extended work hours.

Coordinate with Other Stakeholders

To protect inhabitants of the service area, it’s critical to cooperate with the federal, state and/or local emergency management departments and collaborate to prepare a customized, comprehensive plan. These public safety officials have the authority in all jurisdictions to enforce evacuations, and it’s essential for all stakeholders (including other utilities, law enforcement, transit agencies, and local businesses) to follow their instructions in disaster situations. The emergency management department has planned for the worst-case scenario (such as a downed power line over a major road) and developed redundant evacuation routes to get people out of harm’s way. Make sure personnel are informed on the latest version of this plan. Prepare a procedure on how to communicate real-time hazard updates and outages with customers and other affected stakeholders.

Much like planning and preparation, response and recovery sometimes are seen as interchangeable, but the distinction in this context is important. Response refers to actions taken during and immediately after a natural disaster, while recovery refers to the more long-term efforts to get a community back on its feet. With aging infrastructure plaguing virtually every service provider, the possibility of failure is looming. The planning and preparedness phases are critical for increasing the resilience of these systems, and those pre-disaster phases should inform response and recovery activities when facing the threat of a system failure.

Prioritize the Three Ps: People, Property and Prevention

Response efforts include protecting people, protecting property, and preventing the situation from escalating. Even if the customer has been evacuated from the service area, the hazards aren’t gone. A damage assessment and triage of district assets needs to be completed to identify and immediately address live electrical wires, damaged substations and fallen poles. Damage assessments can be completed by personnel on foot, by vehicle, through remote-enabled technology such as drones, or a combination of these methods. Energy utilities benefit from employing either in-house or external damage assessment professionals that can be mobilized immediately after a natural disaster.

Safely Repair Assets and Restore Services

Restoration of the power grid continues to be important in the response phase. To ensure a complete restoration of operations, deploy crews for repair and replacements as necessary. Conduct adequate testing of repaired equipment and infrastructure before restoring to full operation.

Recovery encompasses long-term and future-focused efforts to restore damaged grid infrastructure and get the community back to “business as usual.” These recovery efforts could take months, years or even decades depending on the severity of the disaster and the region’s level of resiliency. Mitigation activities should be considered while conducting recovery efforts, to increase resiliency and ensure that future disasters do not repeat the same damage to infrastructure.

Leverage Applicable Funding

If an organization is eligible, the recovery phase presents an opportunity when federal funding may become of greater interest. The Infrastructure Investment and Jobs Act (IIJA) provides funding for new and existing programs related to storm resiliency and response. Even with billions of dollars on the table, it can be challenging for energy utilities to navigate the funding available for recovery efforts and the complex requirements. Consider working with an expert consultant partner that specializes in getting the most out of federal grant dollars.

Return to Step 1: Continuous Improvement to Break the Cycle of Devastation

The recovery phase builds upon all the previous steps: planning from years prior, preparation from just before the storm, and damages remaining after the initial response. Although recovery is the “final” step in this context, this is actually where the resiliency journey makes a full circle back to the planning phase. Reflecting on lessons learned and continuously improving the resiliency plan is essential to prevent history from repeating itself.

Storm-related dangers are only increasing in severity. Half of all U.S. states will be in the top 5% most at-risk locations in the world by 2050. Many grid systems are built upon aging infrastructure and are at risk of catastrophic failure. Many energy utilities haven’t been able to make upgrades due to complicated funding qualifications or uncertainty about the best path forward. Fortunately, expert advisory partners are available to help utilities navigate all the complexities of developing a robust and comprehensive storm resiliency strategy.

At the end of the day, the core mission is to ensure uninterrupted power for customers, regardless of the challenges posed by nature. Although all four of these steps -- plan, prepare, respond and recover -- are important, planning cultivates the biggest opportunity to mitigate risk and bolster resiliency. Mapping out resilience before critical infrastructure is even built is ideal. Collaborating with a design-build expert that offers a full suite of engineering, construction, management, funding advisory, and storm readiness services can provide numerous advantages for both new and existing assets. By partnering with a company that offers all these capabilities in-house, providers can benefit from a streamlined process that ensures continuity and consistency throughout the project lifecycle. This approach can help to optimize project outcomes, reduce delays and budget overruns, and ensure that assets are well-equipped to withstand natural disasters and other disruptive events.
