  1. What is the primary purpose of a SCADA system in BGE's grid operations?

    Answer: To monitor and control grid equipment remotely in real time

    SCADA (Supervisory Control and Data Acquisition) systems allow operators to monitor and control grid components—like switches and breakers—remotely and in real time.

  2. Which organization sets reliability standards that BGE must follow as a transmission owner?

    Answer: FERC-delegated NERC

    NERC (North American Electric Reliability Corporation), under authority delegated by FERC, sets and enforces mandatory reliability standards for bulk power system owners like BGE.

  3. A distribution feeder experiences repeated voltage sag complaints from customers. Which device is BEST suited to correct this issue?

    Answer: Voltage regulator

    Voltage regulators automatically adjust voltage levels along a feeder to compensate for load-induced sags and keep voltage within acceptable limits.

  4. What does the term 'N-1 reliability criterion' mean in transmission planning?

    Answer: The grid must survive the loss of any single major element without cascading failure

    The N-1 criterion requires that the bulk power system remain stable and within operating limits even after losing any single element, such as a line or transformer.

  5. BGE's transmission system operates primarily at which voltage level?

    Answer: 115 kV to 500 kV

    BGE operates its transmission network at high voltages ranging from 115 kV to 500 kV to efficiently move large amounts of electricity over long distances.

  6. What is the function of a capacitor bank installed on a distribution feeder?

    Answer: Reduce reactive power demand and improve power factor

    Capacitor banks supply reactive power locally, reducing reactive power flow from the source, improving power factor, and reducing line losses.

  7. Which metric does BGE use to measure the average number of times a customer experiences a sustained outage per year?

    Answer: SAIFI

    SAIFI (System Average Interruption Frequency Index) measures the average number of sustained interruptions per customer per year.
