Space Weather Prediction Testbed 2026 Bulk Electric System Exercise

The 2026 Space Weather Prediction Testbed Bulk Electric System (BES) Exercise will evaluate prototype decision-support services designed to improve how geomagnetic storm risk is communicated and applied in BES real-time operations. Through an operator-in-the-loop simulation, the exercise will assess whether modernized products provide actionable, user-driven, and risk-based information for preparedness, response, recovery, and all-clear decisions under operational uncertainty. The exercise will also examine how emerging scientific models, probabilistic forecasting techniques, and prototype applications can improve operational decision-making. Participant feedback will directly inform the development of next-generation space weather services that are aligned with real-world operational workflows.
