"Recent events that cause long term downtime (i.e. catastrophic weather patterns) create many challenges to provide communication services to the right emergency response groups at the right time.
Applying Adaptive Power tools and techniques will allow the Critical Facility – CF (Headend or Hub) to:
• Selectively reduce energy consumption at the CF
• Allow power only to selected communication capability supporting Emergency Response needs
• Effectively turn down non-essential network elements and service delivery equipment
• Reducing over-all CF load
• Extend runtime of the backup generation
• Effectively restore to standard operation when emergency is cleared
Critical facilities have set operational plans to ensure availability and resiliency (via - back-up energy generation) to sustain the facility. NREL Studies have shown that the typical backup generator has only 2 days-worth of fuel before requiring refill.
Applying Adaptive Power in a systematic approach to monitor and control energy at the Critical Facility (CF) during a major power outage can help ensure service continuity to - First Responders, Local & State Agencies, Communication Towers, etc. This is not intended for every Headend or Hub. However, the cable service delivery network has evolved: Missing from this illustration are all the other communication facilities and links to subscribers that are not typical “triple play” customers. Providing connectivity and communication to these Emergency Response groups allows effective coordination with each other and outside the affected area.
Adaptive Power as a tool to power down network elements in the critical facilities is the first step. This allows the energy generation by the generator or other energy source to support a modified or smaller critical load.
If the reduced load is significant then there is the potential to extend the run time on the backup generator. NREL studies have indicated that recent weather related incidents and resulting down time of infrastructure have been averaging longer than 2 days.
This implementation is intended for those CFs that are strategically located in the Metro Region and clearly Network Engineering, Operations and Facilities would need to establish the exact items in the CF that need to be managed. However, with that plan there is a strong potential for providing effective communications to Emergency Response needs and optimize the resiliency of the CF by utilizing Adaptive Power tools and techniques.
" Applying Adaptive Power in this scenario has a two-fold impact. First the systematic turn down of network elements and service delivery equipment is needed because newer technologies require a power off sequence. One cannot just un-plug this equipment.
Once utility power is restored at the CF there is the need to reenergize the network elements and service delivery equipment. This is not just flipping a switch.
The challenge is to bring back full operation of the network elements and service delivery equipment requires the reverse of the shutdown process.
This is the second impact of applying Adaptive Power. The same sequence that powered down can be applied in reverse to sequentially power up the CF with minimum manual intervention.
The result, a disaster recovery plan that optimizes the CF network elements and service delivery equipment load requirements:
• allowing for selected communication capability to Emergency Response needs
• effectively turning down non-critical network elements and service delivery equipment
• potentially reducing CF load
• extending the runtime of the backup generation
• effectively get back on-line when infrastructure is restored
o in a managed cost effective approach
o With minimal manual intervention.
