arXiv (Texas Tech University) 2021
In a data-centre LV system with generator backup, run the arc-flash study for both grid-connected and islanded topologies, and check that the much lower islanded fault current (1,296 A instead of 22,793 A) does not lengthen clearing time.
Teksan 2025
Add DCP to the rating-class field of the generator catalogue and set 'utility parallel allowed' to false for it.
Uptime Institute 2010
Avoid labelling designs by N-count; run a path-based concurrent-maintainability analysis in Tier advisory tools.
Siemens 2018
Offer W/m2 defaults by building type (data centre vs IT room) and redundancy-dependent simultaneity factors in early sizing.
Cummins 2025
Store per generator the ISO 8528-5 class achieved, BMEP at rated load and the maximum single load step (%) that meets the stated dip limits.
Uptime Institute 2021
When building a failure-mode catalogue, list the UPS, ATS/STS and generator as the main power-outage contributors.
Uptime Institute 2026
Add an onsite primary generation scenario (gas turbine or engine) to the power module.
Caterpillar 2021
Warn when planned monthly exercise or normal running load is under 30% of rating, and recommend load-bank testing or a reduced set count.
Vertiv 2024
Extend the power-source library beyond utility plus diesel: BESS (AC- or DC-coupled to the UPS), SOFC prime power, PEM backup fuel cell, PV and CHP, each with fuel type, start time, ramp capability and emissions factor.
Schneider Electric 2011
Use it as a quick-sizing calculator in novice mode: take IT kW, future kW, floor area, cooling type and UPS input type, and output service kW/A and generator kW, with the multipliers as editable defaults.
FEMA 2007
For site selection, look beyond the 100-year flood to the 500-year (0.2%) flood and the facility's occupancy category, and avoid flood hazard areas where possible.
FEMA 2014
At critical-facility data centers, place generators, ATS, fuel tanks and pumps above the greatest of BFE + 3 ft, DFE + 1 ft and 500-year elevation + 1 ft, and prefer elevation to dry floodproofing.
Schneider Electric 2018
Run a generator check: estimate leading kVAr from the IT kW on the non-UPS or bypass path and the PSU load percentage.
Cummins India Limited 2020
Build the fuel curve from the selected model and rating; do not reuse these numbers for other generators.
Meta 2026
Add a fuel-type parameter to the generator catalog {diesel, HVO, natural gas, dual-fuel}, with HVO as a drop-in option for the same genset.
Cummins 2022
Take site conditions (altitude, temperature) and nonlinear-load factors as evidenced inputs.
Schneider Electric 2022
Keep fuel type (diesel, HVO, natural gas, fuel cell, BESS) as a field in the generator catalogue
Uptime Institute 2018
For Tier III/IV targets, accept only generator ratings flagged 'continuous' or unlimited-hours in the sizing module
Headquarters, Department of the Army (U.S. Army Corps of Engineers PREP) 2006
When modelling the power and cooling chain use these values as starting failure rates and MTBF/MTTR inputs and convert them into availability with the method of TM 5-698-1.
Siemens 2013
Use the tier factors as defaults in the early-stage area estimator: grey space = white space x factor.
U.S. DoD (UFC) 2025
Select supply voltage by demand load (208Y/120 V below 150 kVA, 480Y/277 V above) and attach a life-cycle comparison to the design analysis if 208Y/120 V is proposed for a larger data hall.
U.S. DoD (UFC) 2023
Include transient and steady-state loads, transformer inrush, motor starting and UPS load in the generator sizing study, and calculate UPS charging load using the minimum charging current allowed while on generator.
Schneider Electric 2024
Add BESS as a site energy asset with kW, kWh and chemistry inputs
POWER Magazine 2024
Use it as a negative test case: the app's Tier explanations must not hard-code availability percentages or equate Tier IV with '2N+1'
