January 11, 2019 Eastern Interconnection Forced Oscillation Event

On January 11, 2019, a steam turbine at a combined cycle power plant in Florida experienced a faulty input to a control system that resulted in oscillations that persisted for around 18 minutes before the plant operator manually removed the unit from service.

The goal of this report is to document the root causes of the oscillation, determine the reasons for propagation of the oscillation throughout the EI, and provide key findings and recommendations to the industry for proactive mitigation of potential future oscillation events.
