Grid Resilience

The power grid has vulnerabilities that can be exploited by manmade and natural events. INL plays a leading role in protecting the modern power grid from cyber and physical threats.



INL solves national challenges with technology innovations that provide intelligent sensors and wireless communications to enhance the resilience and security of the Smart Grid, secure control systems to reduce the threat of cyber attack, and physical devices and barriers to protect substations and transformers from geomagnetic disturbance and ballistic attacks.

Critical Infrastructure Test Range

INL’s Critical Infrastructure Test Range allows for scalable physical and cyber performance testing to be conducted on industry-scale infrastructure systems. It includes an Electric Grid Test Bed and a Cyber Security Test Bed.


The complexity of the systems that make up our critical infrastructures requires that actual systems be used for testing and validation. These tests give an understanding of the complex interaction of a real integrated infrastructure. The Test Range allows organizations to visualize, analyze, and test their infrastructure systems in a domain that is more realistic than computer simulations, yet safe and secure.

Electric Grid Reliability

To help protect the modern power grid from cyber and physical threats, INL performs full-scale, end-to-end grid reliability testing for industry and government.


In addition to conducting vulnerability assessments in Idaho, INL engineers and cyber specialists perform on-site assessments at transmission and generation control centers and at substation automation installations throughout the United States.

INL’s Electric Grid Test Bed

INL facilities are spread across 890 square miles in clusters similar to modern cities and other environments. Because of this, INL operates its own electrical power transmission and distribution system.


It is a 61 mile, 138kV dual-fed power loop complete with seven substations and a control center, all linked with state–of–the–art communications and instrumentation capabilities. Portions of the power loop can be isolated and reconfigured for independent, specialized testing.


Real Time Digital Simulator

In collaboration with the Department of Defense, cyber and electric grid reliability researchers at INL have acquired and are using the physics-based Real Time Digital Simulator for enhancing the security of the nation’s electric power grid and related control systems including supervisory control and data acquisition systems. It allows engineers to visualize the effects of power grid failures. With 15 racks, INL has the largest installation of RTDS in the national lab system.

The ability to simulate real–time power grid information is a key factor in detecting previously unknown vulnerabilities and providing infrastructure owners and operators with a path forward for responding to grid failures. The simulator allows critical infrastructure protection specialists to predict, plan and prepare for catastrophic events.

Instrumentation, Control and Intelligent Systems

Instrumentation, Control and Intelligent Systems (ICIS) research is centered on developing components, programs, systems and individuals for any application that requires monitoring, control, and human interaction.

External peer review and advisory committees made up of academic, R&D, and customer organizations provide independent and ongoing review of the strategy within the signature and the focus or research funds.
