Adtran announced that a leading Canadian hydropower producer is using its Oscilloquartz grandmaster device combined with its optical cesium atomic clock to achieve new levels of precision, reliability and resilience in its power grid synchronization network. The deployment addresses the urgent need to implement the highest standards of protection against GNSS disruptions, including jamming and spoofing cyberattacks, and helps bolster North America?s energy resilience. Featuring multi-source protection, the enhanced timing architecture offers a zero-trust approach to positioning, navigation and timing (PNT), ensuring robust and accurate synchronization.

It also seamlessly supports existing services, enabling a smooth transition from legacy timing to power grids with advanced PTP technology. For streamlined operations and assurance, the synchronization network is remotely managed through the Adtran Ensemble Controller with Sync Director. It?s great to be helping another major utility to modernize its timing infrastructure and prepare for next-generation smart grid applications.

The transition from traditional TDM to advanced packet-based synchronization marks a significant milestone for this forward-thinking power supplier. The solution will also strengthen its timing network against the growing dangers of relying solely on GNSS,? commented John Scherzinger, GM of Americas sales at Adtran.

?The deployment of advanced grandmaster clock enables the utility to extend reliable timing to Canada?s most remote regions. The superior stability and precision of optical cesium clock are key to realizing levels of accuracy and resilience never seen before. What?s more, Ensemble Sync Director system brings the benefits of centralized control, ensuring comprehensive monitoring and simplified operational management.

This is essential for maintaining the reliability and security of the utility?s extensive and often remotely located network. By enhancing its timing framework with Adtran?s Oscilloquartz solution, the hydroelectric producer is ensuring it maintains the highest standards of cybersecurity and energy reliability in its critical infrastructure. The deployment will also improve the stability and security of the energy supply across Canada and the US.

The new solution includes Adtran?s OSA 3350 ePRC+ combined with its highly versatile OSA 5422 to provide the highest precision, stability and resilience against GNSS vulnerabilities. Featuring an all-digital design, the OSA 3350 ePRC+ utilizes optical-pumping techniques, guaranteeing timing accuracy and optimal stability for over a decade ? twice the lifespan of conventional cesium clocks.

Together with the OSA 5422, the solution future-proofs the utility?s timing network and assures compliance with governmental regulations. It also fortifies security and underscores the renewable energy utility?s commitment to maintaining a continuous, secure power supply.
