A More
Resilient Grid

The U.S. Department
of Energy Joins with
Stakeholders in an R&D Plan
E
ELECTRIC DISTRIBUTION GRID RESEARCH AND DEVELOPment (R&D) has long focused on the reliability, affordability, flexibility,
and efficiency of electricity delivery for end users; however, this focus
has primarily been outside the realm of severe climate events. Due to
the increasing frequency and intensity of weather-caused grid outages
in recent years, the U.S. Department of Energy (DOE) has placed an
added emphasis on R&D to enhance resilience to climate change and
extreme weather. To forge a focused national R&D effort on grid resilience, the DOE is adopting a public/private partnership approach to join
with key stakeholders in developing and implementing a resilient grid
R&D plan. This article presents the plan development process and the
R&D need areas identified for pursuit.
Weather and Climate Disasters
and Grid Resiliency
From 1980 to 2014, a total of 178 weather/climate disasters occurred in
the United States, with overall damages/costs reaching or exceeding US$1
billion for each event and US$1 trillion for all events. Eight of these events
occurred in 2014, as shown in Figure 1. Both the frequency and intensity
of these disaster events have been trending higher in recent years, with
seven of the ten costliest storms in U.S. history occurring in the last ten
years. These weather disaster events represent one of the most significant
threats posed by climate change.
With increasing dependence on electricity for most daily activities
and vital services (such as transportation, commerce, communications,
health care, water, and emergency responses), an urgent need exists to
