Bear Valley Electric Service enhances grid automation with fiber optic upgrades

Bear Valley Electric Service (BBS) is making significant strides in enhancing its grid automation as part of its 2026-2028 Base Wildfire Mitigation Plan (WMP). The utility company has been laying the groundwork since 2019, focusing on advanced communication technologies to improve infrastructure resilience and operational efficiency.

BBS has opted for fiber optic communication as the backbone of its major infrastructure, including substations and a 34 kV sub-transmission line. This decision allows for real-time communication between field devices and the central Distribution Management Center, which was established during the 2020-2021 period. While fiber optics cover critical infrastructure, BBS also employs radio communication to connect with additional field devices, ensuring comprehensive monitoring capabilities.

As part of the ongoing WMP, BBS has automated three substations annually, with plans to complete full automation by the end of this year. This automation enables better monitoring of equipment and enhances the utility's ability to respond to potential issues. Additionally, BBS has replaced outdated explosion fuses with modern electronic fuses, further improving system reliability.

Looking ahead, BBS plans to upgrade two more substations in 2026, continuing its commitment to modernizing infrastructure. The utility has also implemented a quality control process for new equipment, ensuring thorough testing before installation to mitigate the risk of equipment failure.

BBS's SCADA system plays a crucial role in this modernization effort, providing real-time monitoring and control capabilities at both the substation and circuit levels. This system not only tracks equipment status but also logs historical data, allowing BBS to benchmark equipment life expectancy and schedule necessary maintenance or replacements.

Through these initiatives, Bear Valley Electric Service is positioning itself to better manage wildfire risks and enhance service reliability for its customers, demonstrating a proactive approach to infrastructure safety and resilience.
