The Center for Alternative Synchronization and Timing (CAST) at Oak Ridge National Laboratory (ORNL) performs research, development, testing, evaluation, and technical assistance to enable resilient timing and synchronization for the power grid. Working closely with power utilities, timing hardware and software vendors, network operators, and federal stakeholders, CAST helps develop and validate alternative timing architectures to augment GPS time. CAST also translates and transfers ORNL’s research and development (R&D) advances in secure timing and grid communications to power sector applications, and engages across the broader timing community to develop best practices to ensure the resilience of US critical infrastructure. CAST was established in 2021 and is sponsored by DOE’s Office of Electricity.
