This paper examines expert perceptions of enhancing grid resilience with electric vehicles in the United States.
Electricity and transportation systems in industrialized countries are undergoing transformations that, if coordinated, could improve the resilience and environmental performance of energy systems. The electrification of transportation and the expansion of renewable electricity can be leveraged by the bidirectional smart charging of electric vehicles, called “vehicle-grid integration” (VGI). Studies to date have focused on simulations and pilot studies to estimate the technical potential of VGI. We survey members of the U.S. Department of Energy’s Electricity Advisory Committee using a Delphi approach to assess VGI’s …View Full Resource
This issue brief provides a summary of the Federal Energy Regulatory Commission (FERC)’s decision
on the Department of Energy (DOE)’s Proposed Rule on Grid Reliability and Resilience Pricing. The
proposed rule provided cost recovery to coal and nuclear power under the guise of promoting grid
resilience with preference for a 90-day supply of on-site fuel. On Jan. 8, 2018, FERC issued an order
to terminate the rulemaking proceeding and established a new proceeding to gather additional
information on resilience. FERC’s decision was a 5-0 unanimous agreement, with concurring
opinions by Commissioners Cheryl LaFleur, Neil Chatterjee and Richard Glick. The independent…
On September 28, 2017, the US Department of Energy (DOE) issued a Notice of Proposed Rulemaking (NOPR), proposing significant changes to the nation’s wholesale markets for electricity. The NOPR directs the Federal Energy Regulatory Commission (FERC) to develop new tariffs to compensate unregulated units with a 90-day on-site supply of fuel for their “operating and fuel expenses, costs of capital and debt, and a fair return on equity and investment.”2 The full text of the memo makes clear that the rule is intended to apply to coal and nuclear facilities, which it mentions as having firm on-site fuel.
The proposal …View Full Resource
The nation’s grid delivers electricity that is essential for our modern life.
However, risks such as extreme weather, cyberattacks, and electromagnetic events like solar storms can damage our electrical infrastructure (like power lines) and communications systems. The resulting power outages can threaten the nation’s economic and national security.
With examples drawn from several GAO reports, we describe these risks and highlight key opportunities to improve federal efforts in this area.…View Full Resource
Customers choose to install microgrids based on a wide range of motivations, which often include increasing reliability and resilience, decreasing electricity costs, expanding access to clean energy, and/or providing power to remote communities (e.g., when extending the existing transmission/distribution grid is infeasible or too costly). Customer motivations are not mutually exclusive; in fact, customers often have multiple motivations for installing a microgrid, such as increasing renewable generation while improving reliability and resilience. This paper cites numerous examples of operational microgrids across the country that represent one or more of these objectives.…View Full Resource
Buildings drive up to 80 percent of the peak demand on energy grids in the United States. As utilities incorporate more time-of-use pricing based on the cost or carbon intensity of the electricity being generated, grid interactivity has become more important and valuable than ever.
Grid-interactive efficient buildings (GEBs) are energy-efficient buildings that flex their energy load from one time to another based on the cost or carbon intensity of grid electricity. GEBs are constantly responding to minute changes to grid price and carbon intensity, resulting in more beneficial integration between buildings and the grid that can reduce utility costs …View Full Resource
This Applied Economics Clinic policy brief—prepared on behalf of GreenRoots, a resident–led organization working to achieve environmental justice in Chelsea, East Boston, and surrounding communities—presents ways in which microgrids, depending on their design, can provide opportunities for vulnerable communities to realize important benefits. We define characteristics of “sustainable community microgrids” that have the potential to enhance grid resilience, lower electric bills, improve public health and strengthen the local community when equitable outcomes are prioritized throughout the project.…View Full Resource
Electric utilities are facing new challenges in the United States. Here in the West, we are beginning to experience the direct impacts of climate change, through extreme weather, droughts, reduced snowpack, and wildfires. A hotter, drier climate intensifies wildfire risk and severity. Electric utility infrastructure—like high-voltage transmission lines—have always posed fire risks, but those risks are now much greater than when those facilities were initially constructed. This has led utilities to commence preventative emergency disconnection of electricity service as a tool to mitigate the risk of utility infrastructure sparking deadly and devastating wildfires. These interruptions in service, while reducing wildfire …View Full Resource
California’s electricity infrastructure is entering a period of profound change. From a policy perspective, the state is moving toward goals of 60 percent renewable electricity by 2030 and 100 percent zero-carbon power by 2045, while state and local governments are striving to electrify more buildings and vehicles. At the same time, climate change is destabilizing these efforts, as extreme heat waves and record-setting wildfires are leading to electricity demand spikes, public safety power shutoffs, and questions about the reliability and resilience of an increasingly renewable-powered grid.
As the grid becomes more defined by flexible, distributed assets that generate, store, and …View Full Resource
In fall 2019, the National Association of Regulatory Utility Commissioners (NARUC) and the National Association of State Energy Officials (NASEO) initiated a joint Microgrids State Working Group (MSWG), funded by the U.S. Department of Energy (DOE) Office of Electricity (OE). The MSWG aimed to bring together NARUC and NASEO members to explore the capabilities, costs, and benefits of microgrids; discuss barriers to microgrid development; and develop strategies to plan, finance, and deploy microgrids to improve resilience. Based on member input, the MSWG developed two companion briefing papers to answer key questions about microgrids: (1) User Objectives and Design Approaches for …View Full Resource
