Session 3: Best Practice Combinations of
Alternate Power Sources to Provide Optimum Duration
List of Sources
Best Practices – Existing (Wireline)
-
Battery = 8 hours for OSP (sufficient?)
Generator
-
Fixed Generators (typical 72 hours fuel)
Portable Generators (DOT limits to ~200 gal transport w/o fuel trailer)
Best Practices – Existing Technologies (Wireless)
-
Battery = 2-4 hours (up to 8 hours) is cell site norm
Generator (not at every sites)
-
Fixed Generator at Critical Sites
-
-
not typical at most Cell Sites
Local Factors determine fuel storage (3 days fuel would be desired – not always doable)
Best Practices – Data Centers (IDCs, Multi-tenant/Co-locations)
-
More typical AC environments with large UPSs
Dual commercial power sources is common
Generators: minimum is n+1, n+2, …

Session 3: Best Practice Combinations of
Alternate Power Sources to Provide Optimum Duration
List of Sources
Existing Technologies:
•
•
•
Wireline/Wireline - Battery backed up by generators
IDC’s – Dual AC commercial w/UPS & Generator backup
Backup Generators: Natural Gas + Diesel OR Natural Gas + LPG backup (Dual Fuel)
Emerging Technologies
Lead Acid:
Issues: human cost/maintenance, life cycle, environment impact
New Battery Types:
Higher initial cost – Lower life cycle
Human Cost (tech training, …)
Fuel Cells:
Alternate to either Battery or Generators
Issues/Concerns:
- Delivery of fuel
- Storage of fuel issue (Power requirements >10Kw)
