NEW GR
Generic Requirements for Energy Generators for Remote Telecommunication Facilities, Issue 1

Telcordia proposes that a new GR be developed to define the functional performance requirements needed for energy generators and storage systems — primary (distributed power), secondary (backup), or hybrid systems that are designed to provide power to telecommunications equipment in remote applications (huts, cabinets, towers). Such distributed and backup power systems are necessary to support the increasing demands of widespread wireless cell sites, and anywhere-anytime broadband communication services.

This new GR will include the generic powering requirements as well as the criteria to address the anticipated environmental, mechanical, electrical and operational stresses under which these systems are required to provide reliable power. The intent is for this GR document to include, but not be limited to, the following general areas:

• Physical Design Criteria - Spatial, Acoustic, Illumination Requirements
Environmental Operational Tolerances and Criteria - e.g., temperature, humidity, altitude
• Thermal characteristics - Such as heat dissipation, cooling efficiency, equipment airflow criteria
• Physical robustness - Resistance to earthquake, vibration, fire, and other stresses
• Electromagnetic Compatibility (EMC) Issues - Surges, transients, corrosion, bonding, and grounding
• System Integration - Alarm capability and remote sensing systems
• Safety - Operational "fail-safe" ability and fuel system controls
• Power Quality of Delivered Power (DC or AC) - Voltage control, load following, noise characteristics, etc.
• Operational - maintenance, installation, remote communications/control, and design lifetime (20+years) requirements
• Regulatory requirements in terms of applicable building, electrical, and safety codes
• Quality and Reliability requirements - e.g., TL9000/ISO9000.

The systems addressed in this GR shall include powering schemes based on gasoline/diesel engines, solar, wind, flywheels, fuel cells, smart battery technologies, and other generator technologies. These systems can be located in or adjacent to Controlled Environmental Vaults (CEVs), Telecommunications Huts, Electronic Equipment Cabinets (EECs), pedestals, or customer interfaces in the outside plant environment.

This new GR document shall draw relevant and applicable requirements from other communications documents that have helped maintain the highly reliable and available communications network of today, including the following Telcordia documents:

• GR-513, Power Requirements in Telecommunications Plant
• TR-1293, Generic Requirements for Permanent Engine-Generators for Remote Electronic Sites
• SR-4482, DC Bulk Power System for Confined Locations
• GR-3108, Generic Requirements for Network Equipment in the Outside Plant (OSP)
• GR-1089, Electromagnetic Compatibility and Electrical Safety - Generic Criteria for Network Telecommunications Equipment.

The Value of Participation

With the increased widespread demand for communications services to be continuously efficient and reliable, Telcordia proposes this new GR to address and define performance requirements to ensure that energy generators and storage systems in remote applications never fail. As a participating company in this Telcordia Technical Forum (TTF), you will have the opportunity to influence the content of the new GR and specifically have input into new requirements as well as give consideration to existing requirements.

Telcordia Invites Your Participation

Pursuant to provisions of the Telecommunications Act of 1996, related to the development of industry-wide generic requirements, Telcordia invites all interested parties to participate in the development of this new GR. If your company is interested in participating in this activity, please contact Telcordia. The resulting document will only be available through the purchase of an Enterprise License. Such a license is provided under the participation fee for this project.

To proceed with this new GR, it is expected that Telcordia will need at least four industry participants. While the project can proceed with fewer participants, the scope of work may need to be scaled back accordingly. Participating industry members will be apprised regularly of project status and change in scope.

A preliminary conference call for all interested participants in this GR development project is scheduled for December, 2011, at which time project details and status will be discussed. Please contact the project manager below for conference call details. If this date is not convenient, one-on-one discussions can be arranged with the project manager.
