Electricity production and distribution in the United States heavily relies on an aging infrastructure. With more than 10,000 power plants, 642,000 miles of high voltage lines, 56,000 substations, and 6.3 million miles of local distribution lines, much of the infrastructure has exceeded 30 years of service. This aging infrastructure, coupled with the increasing frequency and intensity of extreme weather events such as hurricanes, heatwaves, wildfires, and winter storms, raises concerns about the resilience of the nation’s power grid. In recent years, the US has experienced a significant number of costly extreme weather events, resulting in prolonged blackouts and infrastructure failures. To mitigate these risks, a team associated with the Emerging Energy Markets Analysis initiative at Idaho National Laboratory has developed a novel framework for assessing the resilience of critical infrastructure. This analytical framework takes into account various factors beyond just technical considerations.
The Meta-Level Framework developed by the team at the Idaho National Laboratory provides a comprehensive approach to assessing the resilience of power infrastructure. Unlike traditional frameworks that focus solely on quantitative measurements, such as the cost of interrupting power or hardening a system, the Meta-Level Framework incorporates qualitative factors, including social costs and ecological impacts. By considering these non-technical factors, the framework enables a more holistic understanding of resilience and helps identify important knowledge gaps. It also facilitates the analysis of interdependencies between infrastructure systems, which can have cascading effects during failures. For instance, a power outage can disrupt the operation of a water purification plant, highlighting the need to address the vulnerabilities of interdependent systems. The Meta-Level Framework is a starting point in understanding resilience and emphasizes the importance of future planning.
The Meta-Level Framework was developed under the Emerging Energy Markets Analysis (EMA) initiative led by the Idaho National Laboratory. This collaboration involves several academic institutions and is dedicated to assisting states and regions in transitioning to clean energy technologies, including nuclear energy. The framework’s development is timely, given the recent extreme weather events experienced during the summer of 2023 and the passage of federal laws aimed at enhancing the resilience of critical infrastructure. The EMA connects communities with academic researchers who can apply the framework to address resilience challenges. This partnership ensures that the analysis conducted is specific to local conditions and enables informed decision-making. By incorporating economic, industrial, community, and environmental influences into the decision-making process, communities can make more thoughtful and resilient choices.
When considering the resilience of power infrastructure, it is crucial to move beyond a narrow focus on technological solutions and consider the broader implications. Resilience should not be solely determined by economic considerations; it must also encompass social and environmental aspects. Thoughtful decision-makers recognize the complexity of these choices and understand that resilience and energy security are high-priority concerns. The Meta-Level Framework facilitates a comprehensive evaluation of various options and helps communities navigate the trade-offs associated with resilience planning. It empowers decision-makers to consider a wide range of factors and aligns resilience with economic, industrial, community, and environmental considerations.
The Meta-Level Framework is just one of several efforts undertaken by the Idaho National Laboratory to advance systems resilience and risk management. Recognizing the importance of bolstering the resilience of critical infrastructure, the laboratory is actively engaged in research and development initiatives in this field. By visiting the websites of the Idaho National Laboratory and the Resilience Program, stakeholders can access further information on the ongoing work and advancements in enhancing resilience across the energy sector.
The United States faces significant challenges in maintaining a resilient electricity infrastructure. To address these challenges, a comprehensive approach that goes beyond technical considerations is essential. The Meta-Level Framework for assessing resilience developed by the Idaho National Laboratory provides a valuable tool for utilities, businesses, and communities to analyze their power infrastructure and make informed decisions. By incorporating quantitative and qualitative factors and considering interdependencies between infrastructure systems, the framework enhances our understanding of resilience. Collaboration between academic institutions and communities through initiatives like the Emerging Energy Markets Analysis further enhances the applicability of the framework in real-world scenarios. Thoughtful decision-makers recognize that resilience is not solely an economic concern but rather a complex and multifaceted challenge that requires consideration of social and environmental aspects. Through a systematic evaluation of options and trade-offs, communities can make informed decisions to enhance the resilience of their critical infrastructure.
