Observations of PV Systems Post-Hurricane

NREL's observations of post-hurricane photovoltaic (PV) systems were shared with PV reliability researchers during the Photovoltaic Reliability Workshop held in Lakewood, Colorado the week of February 26, 2018. NREL hosts an annual Photovoltaic Reliability Workshop (PVRW) so that solar technology experts can share information leading to the improvement of PV module reliability. Such improvement reduces the cost of solar electricity and promotes investor confidence in the technology - both critical goals for moving PV technologies deeper into the electricity marketplace. This presentation is intended to share real world examples of PV survivability during and after Hurricanes Irma and Maria in 2017.

Valuing Resilience

There is a variety of work in progress at NREL that is evaluating the value of resiliency. This presentation summarizes of this ongoing work, which including: 1. The development of quantitative resilience metrics for the power system. 2. The implementation of quantitative, performance-based resilience metrics into existing models and tools 3. Methods for valuing resilience, including a time-varying value of lost load. 4. The extent to which accounting for performance-based resilience metrics and/or the value of resilience could impact investment (planning) decisions related to electricity supply. 5. Developing and implementing a consistent valuation methodology for resilience distribution system field validation projects.

Resilience Roadmap: A Collaborative Approach to Multi-Jurisdictional Resilience Planning

Extreme weather and aging infrastructure are creating unprecedented challenges in the United States and around the globe. Many communities have suffered damages from a variety of weather-related events, such as severe weather such as hurricanes, droughts, increasing temperatures, wildfires, and storm surges. Numerous efforts exist to improve resilience to protect national security, energy and water security, economic well-being, and quality of life. As severe weather events increase in frequency and severity, many cities, states, tribes, and federal agencies are addressing the impacts through resilience planning and measures. In an effort to support communities with resilience planning, the White House Council on Environmental Quality (CEQ) initiated preparedness pilot projects designed to showcase community resilience planning in the City of Houston and the State of Colorado. This publication is the full, technical document, for the Colorado pilot project. The process is also summarized in a user-friendly web-version on NREL's website (visit www.nrel.gov/resilience-planning-roadmap) for easier access and replicability. NASA's pilot project with the City of Houston is summarized separately (visit https://toolkit.climate.gov/case-studies/climate-resilience to learn more). water security, economic well-being, and quality of life.

Best Practices in Resilience Planning

At various levels of government across the United States and globally, resilience solutions are being adopted and implemented. Solutions vary based on predicted hazards, community context, priorities, complexity, and available resources. Lessons are being learned through the implementation process, which can be replicated, regardless of level or type of government entity carrying out the resilience planning. Through a number of analyses and technical support activities across the world, NREL has learned key lessons related to resilience planning associated with power generation and water distribution. Distributed energy generation is a large factor in building resilience with clean energy technologies and solutions.

Distributed Energy Planning for Climate Resilience

At various levels of government across the United States and globally climate resilient solutions are being adopted and implemented. Solutions vary based on predicted hazards, community context, priorities, complexity, and available resources. Lessons are being learned through the implementation process, which can be replicated regardless of level or type of government entity carrying out the resiliency planning. Through a number of analyses and technical support across the world, NREL has learned key lessons related to resilience planning associated with power generation and water distribution. Distributed energy generation is a large factor in building resilience with clean energy technologies and solutions. The technical and policy solutions associated with distributed energy implementation for resilience fall into a few major categories, including spatial diversification, microgrids, water-energy nexus, policy, and redundancy.

Bridging Climate Change Resilience and Mitigation in the Electricity Sector Through Renewable Energy and Energy Efficiency: Emerging Climate Change and Development Topics for Energy Sector Transformation

Reliable, safe, and secure electricity is essential for economic and social development and a necessary input for many sectors of the economy. However, electricity generation and associated processes make up a significant portion of global greenhouse gas (GHG) emissions contributing to climate change. Furthermore, electricity systems are vulnerable to climate change impacts - both short-term events and changes over the longer term. This vulnerability presents both near-term and chronic challenges in providing reliable, affordable, equitable, and sustainable energy services. Within this context, developing countries face a number of challenges in the energy sector, including the need to reliably meet growing electricity demand, lessen dependence on imported fuels, expand energy access, and improve stressed infrastructure for fuel supply and electricity transmission. Energy efficiency (EE) and renewable energy (RE) technical solutions described in this paper can bridge action across climate change mitigation and resilience through reducing GHG emissions and supporting electric power sector adaptation to increasing climate risk. Integrated planning approaches, also highlighted in this paper, play an integral role in bringing together mitigation and resilience action under broader frameworks. Through supporting EE and RE deployment and integrated planning approaches, unique to specific national and local circumstances, countries can design and implement policies, strategies, and sectoral plans that unite development priorities, climate change mitigation, and resilience.
