Burying Short Sections of Power Lines Could Drastically Reduce Hurricanes' Impact on Coastal Residents
As Earth warms, people living near the coasts not only face a higher risk of major hurricanes but are also more likely to experience heat waves while grappling with widespread power outages. Strategically burying just 5% of power lines — specifically those near main distribution points — would almost halve the number of affected residents.

Puerto Rico’s Vulnerability to Hurricanes Is Magnified by Weak Government and Bureaucratic Roadblocks
Hurricane Maria caused extensive damage to Puerto Rico’s power grid in 2017 that left many residents without electricity for months. Rebuilding it has been hampered by technical, political and financial challenges. Now Hurricane Fiona has, again, exposed the sorry state of Puerto power grid.

Better Human-Machine Coordination to Thwart Growing Threats to the U.S. Power Grid
The U.S. electrical grid faces a mounting barrage of threats which could trigger a butterfly effect – floods, superstorms, heat waves, cyberattacks, not to mention its own ballooning complexity and size – which the nation is unprepared to handle. Researchers have plans to prevent and respond to potential power grid failures.

What Would It Take to Survive an EMP Attack?
We are increasingly vulnerable to both natural disruptions and military attacks on our power grids. An electromagnetic pulse impulses (EMPs) would destroy your electronics, leaving you and your surroundings intact — but without easy means of survival. Remember, almost all conventional power sources and the entire internet would be knocked out and might take many months to replace.

Protecting National Public Warning System from EMPs
DHS released a report of operational approaches to protect the National Public Warning System from an electromagnetic pulse (EMP). The report summarizes recommendations that federal, state, local agencies, and private sector critical infrastructure owners and operators can employ to protect against the effects of an EMP event.

Strengthening Puerto Rico's Power Grid
The 2017 Hurricane Maria made a direct hit on Puerto Rico in 2017, it ravaged the island’s power grid and caused the longest blackout in U.S. history. Maria left many residents without power for nearly a year. As more hurricanes threaten, Puerto Rico utilities are shoring up their defenses using the Electrical Grid Resilience and Assessment System (EGRASS) planning tool.

New Dataset Shows Value Building Flexibility Adds to Grid
New study estimates the gross value (including capacity, energy, and ancillary service values) of generic building flexibility in future power systems projected for the contiguous United States using computer modeling. Building flexibility refers to a building’s capability to shed, shift, and modulate electricity demand.
