Uptime Institute Journal (Uptime Institute) 2015

Arc Flash Mitigation in the Data Center

Include an arc flash incident-energy study placeholder and a labelling output for each switchboard in the electrical module.

  • Incident energy is measured in cal/cm2.

Siemens 2020

Arc-fault mitigation in unit substations (white paper)

In the arc-flash module, evaluate incident energy at the LV main line-side terminals using the upstream MV device's clearing time, not the LV main's.

  • MV primary fuse clearing: about 900 ms and 38.3 cal/cm2; LV main with 0.4 s short-time delay: 17.0 cal/cm2.

Arc-Flash Hazards: Standards Development Framework in Facilities of National Importance in Healthcare and Data Centers

Schedule the arc-flash study after the coordination study and make that order a mandatory step in the project plan and model.

  • Example studies assumed available utility fault current of 21,000 A for the 440 V residential service and 21,000-40,000 A for the 480 V/1200 A commercial service.

Best Practices for Large Load Interconnections: A North American Perspective on Data Centers

In a large-load interconnection application, verify the relevant entity's large-load threshold (10-75 MW) and ramp limit (Southern ≤20 MW/min) early; definitions differ widely between entities.

  • Southern Company is the only entity in this review with a numeric ramp cap: ≤20 MW/min under normal operation.

T.C. Cumhurbaşkanlığı Siber Güvenlik Başkanlığı 2026

Bilgi ve İletişim Güvenliği Rehberi - 3.6.2 Sistem Odası/Veri Merkezine Yönelik Güvenlik Tedbirleri (Information and Communication Security Guide - measures for system rooms/data centres)

Provide a Turkey public-sector compliance checklist mapping the measures to design objects: dedicated IT UPS, N+1 air conditioning with auto changeover, redundant feeds, generator fuel redundancy, room adjacency checks against wet areas.

  • Water, power, humidity, temperature and smoke must be monitored with thresholds and alarms; monitoring must not be exposed externally (3.6.2.5).

Open Compute Project Foundation 2026

Clean Backup Power Technology Requirements, Base Specification Version 0.3 (effective Apr 22, 2026)

Extend the generator catalogue with technology type (diesel, HVO, gas, H2 ICE, PEM fuel cell), emissions factor relative to the 1742 lb/MWh baseline, start time, block-load capability and NFPA 110 level.

  • Overload 110% for 60 s and 150% for 3 s; transient voltage response to ISO 8528-5 G3; steady-state frequency within +/-0.5%.

European Commission 2022

Commission Notice on the application of ecodesign requirements on the efficiency of power-supply units in servers and data-storage products and on the power-source efficiency of welding equipment (2022/C 469/03)

When validating server PSU data against the 2023 tier, apply an informational exception, not a hard error, for units placed on the market during 2023 (legacy stock).

  • The Commission expects the problem to be short-term and largely resolved before 1 January 2024.

European Commission 2019

Commission Regulation (EU) 2019/424 of 15 March 2019 laying down ecodesign requirements for servers and data storage products - consolidated text 01.03.2021 (incl. Regulation (EU) 2021/341)

In the IT equipment catalogue store PSU efficiency at 10/20/50/100% load, power factor, active state efficiency (SERT/EN 303470) and declared operating class A1-A4, and validate new models against the 2023 tier.

  • Secure data deletion applies from 1 March 2020; latest firmware and security updates must be made available from 1 March 2021.

Consulting-Specifying Engineer 2008

Commissioning on-site electrical systems

For phased builds, the tool should place load-bank connection points and isolation breakers and output a Cx test list with individual, discrete and integrated levels.

  • The owner estimated a $5 million recovery cost had the load dropped.

CIGRE US National Committee, 2026 Grid of the Future Symposium (arXiv preprint) 2026

Comparative Analysis of Large Load Interconnection Requirements Across U.S. Transmission Entities

Design data-centre UPS and load control to the most restrictive entity's requirement: 6.0 s ride-through at 0.70-0.90 pu (CAISO), six fault-clearing attempts within 90 s (SPP), six 50-70 ms reclosings (Dominion), and the ban on constant-power control (SPP).

  • MISO's proposal requires withstanding three voltage disturbances within 10 s and phase-angle jumps up to 25 degrees.
