FDNY Study Guide: Advanced Meter Infrastructure (AMI) Electric Meter Procedures

Overview of Advanced Meter Infrastructure (AMI) Electric Meters

  • Definition and Identification: Advanced Meter Infrastructure, commonly referred to as AMI meters, serve as the modern replacement for traditional electric meters.
  • Deployment and Prevalence: These meters have been installed in over 90%90\% of residential occupancies throughout New York City. They are utilized across all residential categories, which explicitly includes High-Rise (Hi-Rise) buildings.
  • Primary Functions: The implementation of AMI meters serves three primary organizational purposes:
        * Elimination of Manual Meter Reading: The electric meter reading process is entirely automated, removing the need for physical inspections.
        * Outage Mapping: They allow the utility to accurately determine customer outages following storms.
        * Service Logistics: They facilitate the immediate turning on or off of electric service as tenants or homeowners move in or out of a location.
  • Technology: These meters are read and controlled remotely by the electric utility provider utilizing radio frequency technology.

Functional Capabilities and Automated Monitoring

  • Supervisory Monitoring: AMI meters possess internal monitoring capabilities and are programmed to transmit automated alarms to the electric utility for the following conditions:
        * Tampering: Detected interference with the meter hardware.
        * Temperature Increase: Monitoring for localized overheating.
        * Equipment Failure/Malfunction: Internal diagnostics for hardware errors.
  • Remote Power Regulation: The utility has the capability to perform remote turn-on, remote turn-off, and power reduction. This allows for the regulation of power usage or the total cessation of electric service to a building without requiring a utility crew to respond to the scene or gain physical access to the meter.

Geo-fencing Strategy for Power Removal

  • Definition: "Geo-fencing" is a strategy used by the electric utility to remove power from a designated larger area by establishing specific geographical boundaries and perimeters.
  • Practical Examples of Geo-fencing Requests:
        * Example A: "Remove power for all buildings one block in every direction from 123123 Main Street."
        * Example B: "Remove power for all buildings on Main Street between 1st1^{st} Avenue and 2nd2^{nd} Avenue."

FDNY Incident Commander (IC) Operational Procedures

  • Requesting Power Removal: An FDNY Incident Commander (IC) can request the remote removal of power through the following chain of command:
        * Step 1: The IC makes the request to the FD borough dispatcher via department radio.
        * Step 2: The IC must provide specific identifiers, namely the exact building address for a single building request, or the defined perimeters for a Geo-fence request.
        * Step 3: The FDNY dispatcher contacts the relevant electric control center to request the removal.
        * Step 4: The electric utility initiates the remote removal process immediately.
  • Confirmation Loop:
        * The utility provides confirmation to the FDNY dispatcher once power is removed.
        * The utility must identify any specific buildings where power could not be removed (if applicable).
        * The FDNY dispatcher then notifies the IC, providing the identity of buildings with successfully removed power and the identity of any buildings where power remains active.

Safety Considerations and Technical Risks

  • Tactical Advantages: Remote shut off is deemed advantageous for reducing or eliminating potential ignition sources during specific high-risk scenarios, including:
        * Major gas emergencies.
        * Illegal drug manufacturing operations.
        * Building collapse incidents.
        * Post-explosion operations.
  • Risk of Arcing and Ignition:
        * Direct Arcing: The process of remote AMI meter shut off produces an arc at the meter at the moment the power is disrupted.
        * Secondary Arcing: Small arcs may be created when electronic devices transfer from primary electric power to secondary sources. This includes:
            * Generators.
            * Battery back-up burglar alarms.
            * Battery back-up hardwired smoke detectors.
            * Uninterrupted Power Supply (UPS) units for electronics.
        * Explosion Hazard: In an explosive atmosphere, these arcs can trigger an immediate ignition or explosion.
  • Protocol Compliance: Any power removal conducted in an explosive atmosphere must strictly adhere to the procedures outlined in "Emergency Procedures Natural Gas," Section 9.2.29.2.2.
  • State of the Infrastructure: It is critical to understand that even when remote power removal is successful, electric power remains present up to and inside the meter itself. This is a distinct condition from physical service disconnection, such as when a utility crew cuts a service line on a pole or inside a manhole.

Limitations and Scope of Remote Shutdown

  • Customer Constraints: Remote power removal (including Geo-fencing) is strictly available for residential customers, including those in High-Rise buildings.
  • Life Safety Exclusion: AMI meters will not remotely shut off power to any occupancy that has Life Safety Equipment on record with the utility.
  • Commercial Exclusion: Commercial customers do not have remote shut off capabilities at this time.
  • Utility Type Constraint: Remote shut off is only available for electric service. Gas service cannot be shut off remotely via this system.
  • Administrative Authority: These procedures are established by order of the Fire Commissioner and Chief of Department (A.U.C. 182182, dated August 2424, 20222022).
