The Electric Power Research Institute (EPRI) is an independent, nonprofit center for energy and environmental research. It brings together members, participants, the institute’s scientists and engineers, and other experts to work on solutions to the challenges of electric power. Its members represent over 90 percent of the electricity generated in the United States.
The institute has released guidelines on control systems security, including a report in 2003 and another in 2005. An institute report titled, "Compliance Guidelines for Cyber Security Reliability Standards-2006 Update" (May 25, 2006), provided information, recommendations, and tools to help the electric power industry comply with the mandatory NERC cybersecurity reliability standards.
