The United States' critical energy infrastructure, including its power grid, faces escalating threats from adversaries like Iran, China, and Russia, according to energy security experts. These nations are perceived to be developing capabilities and doctrines that target American domestic energy supplies, posing a risk through cyberattacks, sabotage, and electromagnetic pulses (EMP).

Recent cyberattacks on water systems in at least seven U.S. states, attributed to Iran, serve as an example of these threats. Iranian representatives have explicitly threatened to target American domestic energy supplies and other strategic infrastructure. China and Russia also incorporate attacks on energy infrastructure into their military doctrines, according to reports.

Hardening the Power Grid

Experts propose four key steps to bolster the security of the U.S. power grid against foreign threats. First, the U.S. should mandate that components for critical infrastructure are not manufactured in adversary states, particularly China, which is the largest producer of electricity inverters. These inverters are crucial for making electricity from power plants usable in homes and businesses. The concern is that China could remotely control these components to trigger widespread blackouts, potentially aiding allies like Iran.

Second, the government and utility companies must prioritize secure and reliable electricity, influencing fuel source choices. Third, U.S. electricity systems need to be hardened against cyber-attacks and sabotage. Recent incidents, such as the cyberattack on the Colonial Pipeline and physical attacks on high-voltage power transformers in California, Utah, and Oregon, highlight the vulnerability of existing systems. Despite these events, few substantial changes have been implemented to prevent future occurrences.

Fourth, the nation must develop defenses against electromagnetic attacks. China, Russia, and North Korea are reported to possess EMP capabilities, and Iran was reportedly close to achieving this technology. EMPs can cause significant and lasting damage to electronic equipment.

Hybrid Warfare and Dependence on Technology

The lines between foreign and domestic fronts in warfare have blurred, with hybrid warfare displacing conventional conflict. Adversaries believe that America's reliance on technology presents a vulnerability. Attacks on energy supplies could diminish U.S. advantages during conflicts. Powering military installations largely depends on civilian supply lines, and disruptions could lead to public panic and undermine support for military operations.

Chinese military doctrine, for instance, reportedly includes attacking the U.S. domestic energy sector before any potential invasion of Taiwan. The U.S. military itself is heavily dependent on electricity and electronics for communications, logistics, and weapons systems, making the protection of these resources paramount.

Furthermore, the increasing investment in renewable energy sources in some regions, while beneficial in certain contexts, has added new layers of vulnerability and instability to electricity grids. European nations and Taiwan have made changes to their energy policies, such as closing nuclear power plants, which experts suggest may have compromised their energy and, consequently, their physical security. This could impact the ability of U.S. forces operating in these regions during wartime.

Experts emphasize that while the U.S. has not yet experienced a catastrophic failure, its vulnerability stems from its success and technological advancement. Countries with more developed electrical systems have more to lose from attacks on their energy infrastructure compared to less electrified nations. Protecting the nation's energy sector is therefore identified as a critical priority in response to the threats posed by adversaries.
