Study Findings Help Grid Planners Prepare for the New “Extreme”

A study by NREL and Sharply Focused finds that the impact of extreme weather on the power grid is changing. The analysis produced eight findings that are important in the examination of the weather resilience and resource adequacy of future power system infrastructure. Most notably, the type of weather with extreme grid risks evolved as renewable generation increased. Renewable generation was robust during extreme weather events that drive today’s peak demand, reducing risk during those periods; however, less extreme cold or hot periods concurrent with low wind speeds and/or cloudy conditions can yield extreme net loads, making these events the new extreme concern for energy planners.

How To Realize the Full Value of Interregional Transmission

Transmission across planning regions, or interregional transmission, is becoming more important for decarbonization because the best wind and solar resources are often located far from areas with lots of electricity demand; however, this type of transmission requires a new level of coordination across regions. A new study takes a fresh look at today’s transmission market and operating rules to identify the potential changes that are needed to maximize the value of interregional transmission. This work is part of the National Transmission Planning Study led by the U.S. Department of Energy Grid Deployment Office in partnership with NREL and Pacific Northwest National Laboratory.

On the Road to Increased Transmission: Four Options for the U.S. Grid

The U.S. power grid is incorporating increasing amounts of clean energy. By 2050, there could be 5 times as much wind power and 10 times as much solar coming online. That means we might need to consider new means to increase transmission on the grid to ensure all that power can reach the areas with the highest demand. NREL produced a brief video on YouTube explaining four options to achieve increased transmission: dynamic line ratings, flexible alternating current transmission systems, higher-voltage alternating current lines, and high-voltage direct current lines. An accompanying series of four web articles dives deeper into each option. Read how each option works, starting with dynamic line ratings.

NREL Partners With Industry Leaders To Prove Out Grid Integration Solutions

“These simulations will help us better prepare for the future,” says Colorado Springs Utilities as it launches a new project at NREL. Colorado Springs Utilities and Dominion Energy were both selected to demonstrate ways distribution utilities can adapt as more of their customers drive and charge electric vehicles, adding load to the grid. The teams will use NREL’s premier capability for grid control research, the Advanced Distribution Management System Test Bed, to validate forward-looking solutions for charging vehicles and improving service for the community.

New Dataset Exploring U.S. Electric Vehicle Charging Load Is Now Available via Demand-Side Grid Toolkit and OpenEI

NREL's open-source demand-side grid tool kit has a new dataset that could aid in planning power and other energy systems. The data, detailed in this report from June 2023, were developed using the Transportation Energy & Mobility Pathway Options (TEMPO™) model and outline three scenarios through 2050: Annual Energy Outlook Reference Case, which aligns with the U.S. Energy Information Administration Annual Energy Outlook 2018; Electrification Futures Study High Electrification, which aligns with the High Electrification scenario of the Electrification Futures Study; and All EV Sales by 2035, which assumes average light-duty passenger electric vehicle adoption sales reach 50% in 2030 and 100% in 2035. The dataset provides county-level, hourly data for the contiguous United States for the three light-duty passenger electric vehicle adoption scenarios. The data also differentiate between 60 household bins, 12 vehicle types, and 2 charging types. View the new TEMPO dataset on OpenEI.

Publications Roundup

Autonomous Energy Systems: Building Reliable, Resilient, and Secure Electrified Communities, NREL Fact Sheet (2024)

Technological changes across energy systems are forcing utilities and operators to reconsider their methods for managing power delivery, but few operators have adopted advanced controls and operational software. The challenge is that every system has peculiar requirements, and the available solutions are relatively new, untested, and difficult to integrate into an operational environment. Through extensive collaboration with utilities and cooperatives, NREL has realized the need for the autonomous and optimized management of energy resources, leading to the development of autonomous energy systems, a packaged set of controls that is ready to be integrated into existing control rooms.

Exploring Equality and Sustainability Trade-Offs of Energy Transition Outcomes in the United States in 2050, Applied Energy (2024)

With increasing focus on an equitable and just energy transition, it is critical to understand the trade-offs of different decarbonization outcomes across economic, environmental, and social sustainability criteria. In this analysis, the authors use a multicriteria decision analysis to quantify sustainability outcomes across 32 decarbonization outcomes in 2050 in the United States. They evaluate performance across these criteria under 11 different stakeholder preference scenarios. They find that decarbonization policies with indefinitely extended tax credits have the highest sustainability score under equal criteria weighting, with greater investments in renewable energy technologies, and result in better environmental, system cost, job, and air pollution disparities compared to mid-case scenarios, which include only current policies and carbon dioxide reduction targets.

Reducing Current and Future Risks to Energy Security, NREL Fact Sheet (2024)

As global communities transition to clean energy technologies, the threat landscape for energy security is more complex than ever before. Although broad adoption of clean energy technologies has progressed across the world, NREL has been researching how to reduce risks and the value renewable energy technologies bring to improved energy security, today and decades into the future. Continuing to adopt technologies to meet clean energy and climate mitigation goals requires consideration of energy security, making NREL’s risk reduction and mitigation research increasingly important.

Strategies for Considering Environmental Justice in the Early-Stage Development of Circular Economy Technologies, Sustainable Chemistry & Engineering (2024)

The circular economy could transform how industry and society approach resources and waste, resulting in significant environmental justice implications; however, there are few resources for analyzing the energy justice impacts of new circular economy technologies before they are deployed. This work presents an energy justice framework tailored for early-stage circular economy technologies and showcases its capabilities through a case study on enzymatic plastic recycling. By providing concise, actionable, and accessible guidelines based on technology readiness levels and a series of 20 questions, the framework empowers both experts and nonexperts to evaluate the justice implications of circular economy solutions. Preliminary user feedback highlights the approachability of the framework and its corresponding interactive worksheet as well as their potential to stimulate innovative thinking toward a more just and sustainable future.
