Texas is the only state with an isolated electrical grid, which is vulnerable to electromagnetic pulse (EMP) attacks. An EMP is a strong burst of electromagnetic energy that can disable or destroy electronics over a large area. Texas's independent nature and position as the largest energy producer in the US make it an attractive target for such an attack. While the state has taken steps to defend against EMPs, such as proposing legislation and establishing committees to evaluate and improve grid security, it currently lacks a robust plan to address long-term power outages. Texas's electrical system is not fully EMP-hardened, but ongoing efforts aim to enhance its resilience against this growing technological warfare threat.

What You'll Learn
Texas' independent electrical grid
Texas has its own independent electrical grid, known as the Texas Interconnection. This grid is maintained separately from the two main US grids (the Eastern Interconnection and the Western Interconnection) for political rather than technical reasons. The Texas grid is managed by the Electric Reliability Council of Texas (ERCOT), the first independent system operator (ISO) in the United States. ERCOT manages the flow of electric power on the Texas Interconnection, supplying power to 26 million customers, which is 90% of the state's electric load.
The Texas Interconnection is tied to the Eastern Interconnection with DC ties near Oklaunion and Monticello, and to NERC systems in Mexico with DC ties near McAllen and Laredo. There is also one AC tie switch in Dayton, Texas, though this has only been used once in its history, after Hurricane Ike.
Texas' independent grid means that the state has the opportunity to unilaterally secure its portion of the electric grid from the threat of electromagnetic pulse (EMP) attacks. An EMP is a strong burst of electromagnetic energy that can disable or destroy electronics over a wide area, and it could be produced by a nuclear weapon or by natural disturbances caused by solar storms. While some specialists do not believe EMPs are a significant risk, others argue that they could be used to cause widespread interruption to electricity-dependent societies.
Texas is taking steps to defend its grid from EMP attacks. For example, utilities are deploying tactics that include shielding control rooms with Faraday cages and using new grounded metallic relay houses. Texas has also introduced legislation to increase the security of its electric grid, including the creation of a 10-member electromagnetic threat preparedness task force and a six-member grid security advisory committee.

EMP weapons and their effects
Texas has its own independent electrical grid, separate from the rest of the United States. This makes the state an attractive target for electromagnetic pulse (EMP) attacks, which can cause widespread disruption to electricity-dependent societies. EMPs are strong bursts of electromagnetic energy that can disable or destroy electronics over a wide area.
EMPs can occur naturally, such as during solar storms, or they can be artificially generated through nuclear explosions or non-nuclear means. Nuclear electromagnetic pulses (NEMP) are created as a secondary effect of nuclear explosions, while non-nuclear electromagnetic pulses (NNEMP) are generated without the use of nuclear technology. NNEMP weapons have a much shorter range than NEMP weapons but allow for finer target discrimination.
The effects of an EMP attack can be mitigated through various means, such as shielding control rooms with Faraday cages, using grounded metallic relay houses, and grounding and shielding power supplies. Texas is taking steps to defend its electrical grid against EMP attacks, recognizing the potential threat they pose. The state has proposed bills to develop a disaster preparedness plan, implement threat protection, and set recovery requirements to secure its electrical grid.
EMP weapons have the potential to cause significant disruption to critical infrastructure, communications, and defense systems. They can be used to target specific locations and can be employed by militaries or terrorist groups. The vulnerability of a country to EMP attacks depends on its reliance on computers and electronic systems to control infrastructure and other vital functions.

Texas' vulnerability to EMP attacks
Texas is highly vulnerable to EMP attacks due to its isolated electrical grid. An electromagnetic pulse (EMP) is a strong burst of electromagnetic energy that can disable or destroy electronics over a wide area. EMPs can occur naturally or be triggered by nuclear weapons.
The state's independent electrical grid, which is separated from the rest of the nation, makes Texas an attractive target for EMP attacks. The grid's vulnerability to EMPs has been highlighted by Texas' recent electrical grid failures, which caused significant challenges for Texans, including freshwater shortages.
The potential effects of an EMP attack on Texas could be devastating, resulting in no heating, cooling, light, water, internet, food, or medications for millions. The state's economy, which is the 10th largest in the world, and its large military population could also be severely impacted.
While some specialists believe that EMPs do not pose a significant risk, others argue that these weapons could cause widespread disruption to electricity-dependent societies. Texas has started to take steps to defend against EMPs, with a focus on hardening its electrical grid. The state has proposed legislation to develop a disaster preparedness plan and implement threat protection measures, including the use of Faraday Cages to shield control rooms and grounded metallic relay houses.

Devices to protect against EMPs
An electromagnetic pulse (EMP) is a burst of electromagnetic radiation, creating energy that can easily damage and destroy electronic devices. EMPs are rapid, invisible, and unpredictable bursts of energy that can be produced by a nuclear detonation, powerful natural solar events, or EMP bombs.
Faraday Cages
A Faraday cage is a closed box composed of a conductive material such as metal or plastic, which creates an invisible field that cancels out all electronic energy. Devices inside the cage are protected from damaging currents. Faraday cages can be purchased or built at home using tinfoil.
EMP-Shielding
EMP-shielding reduces the coupling of radio waves, electromagnetic fields, and electrostatic fields, all of which pose threats to electronic systems. EMP Shield, for example, offers shielding for homes, vehicles, and businesses from EMP surges caused by lightning, solar flares, and electromagnetic pulses.
Safe Room Pulse Suppressors
These devices have a built-in magnet or Faraday Shield, which protects the electrical circuitry from intense surges of electromagnetic radiation.
Multi-Zone Safety Appliances
Similar to safe room pulse suppressors, these devices protect electrical circuitry from surges of electromagnetic radiation.
Steel Trash Cans
During an EMP attack, electronic devices can be thrown into a steel trash can with a lid for protection.
While the above devices can help protect against EMPs, it is also important to prepare basic survival supplies, such as food, water, and medical kits.

Legislation to protect Texas' grid
Texas has its own independent electrical grid, which is essentially separated from the rest of the United States. This makes the state an attractive target for electromagnetic pulse (EMP) attacks, which could wreak havoc on the electrical system.
The Electric Power Research Institute (EPRI) has started a three-year EMP research program to counter the threat of EMP attacks. Texas lawmakers have also proposed regulations and legislation to protect the power grid.
One such bill, SB6, aims to prevent a repeat of the deadly outages of 2021, caused by freezing temperatures, and to protect residents and small businesses from massive electricity rate hikes. It would also require companies seeking to develop power-hungry facilities to pay a fee of at least $100,000 to apply to connect to the power grid. The bill would create a new voluntary program that pays large electricity users to reduce power consumption when the grid is strained.
Another bill, SB819, would create a discriminatory and capricious permitting standard that could halt renewable energy development. It would make it much more difficult to build wind and solar energy projects in Texas, threatening to increase pollution, blackouts, and electric bills.
Additionally, a bill proposed by Phil King, known as Senate Bill 6, seeks to put restraints on the state's open-energy market and help the grid plan for the future. It would place more requirements on businesses to help ERCOT better forecast electricity needs and manage the strain on the power grid.
To protect against EMP attacks, utilities are deploying tactics such as shielding control rooms with Faraday cages and using new grounded metallic relay houses. Texas may become a testing ground for defending the grid against EMP attacks, given its independent grid and the fact that it is the nation's largest energy producer.
