Upon telemetry failure of a generator's output, what is the most likely change you would expect?

When a generator's telemetry fails, it indicates that the system is no longer receiving real-time data about the generator's output. In such scenarios, the actual load becomes the most affected variable.

Telemetry systems provide critical information regarding the operational status and output of generators, ensuring that the grid can balance supply and demand effectively. If a generator's output telemetry fails, operators lose visibility into how much power the generator is producing. As a result, they may not be able to manage load appropriately, leading to discrepancies in what the system is expecting versus what it is actually supplying.

Without accurate telemetry data, the control systems can struggle to maintain the balance between generation and load, potentially leading to fluctuations in actual load that could deviate from planned levels. This lack of data could cause operators to either overestimate or underestimate the actual load that could exacerbate stability issues and affect overall grid reliability.

The other aspects, like frequency, ACE (Area Control Error), and tie-line flow, may also be influenced by telemetry failure but the most immediate and prominent change, especially in the context of adjustments made based on generator output, would directly pertain to the actual load. Hence, the actual load is the primary focus in such a scenario as it represents the immediate need for
