PNNL

Abstract

Pacific Northwest National Laboratory has developed this positioning, navigation, and timing (PNT) profile for the energy sector at the request of the U.S. Department of Energy (DOE). DOE is the Sector-Specific Agency for the energy sector and is responsible for providing guidance in the form of this PNT profile, per Executive Order 13905, Strengthening National Resilience Through Responsible Use of Positioning, Navigation, and Timing Services1? (Executive Office of the President 2020)? issued February 18, 2020. Executive Order 13905 directed the National Institute of Standards and Technology (NIST) to develop a PNT profile that is broadly applicable to all sectors and to serve as a foundation for sector-neutral guidance, NIST Internal/Interagency Report (NIST IR) 8323 Foundational PNT Profile: Applying the Cybersecurity Framework for the Responsible Use of Positioning, Navigation, and Timing (PNT) Services. This document builds on NIST IR 8323r1 to serve as specific guidance for the energy sector. For purposes of this PNT Profile, energy sector time is between 0.5 µs (microseconds) and 1?µs precision and accuracy. Currently, the electricity subsector has systems that use this level of precision time, but the oil and natural gas subsector does not. While the electricity subsector uses precision timing, it does not use positioning and/or navigation at this level of accuracy. For this reason, this PNT profile will focus on only precise time for the electricity subsector.
