Independent protection, arc flash, commissioning-readiness, and reliability support for EPCs, colocation operators, utilities, commissioning firms, and infrastructure owners building at hyperscale.
From greenfield design review through live-site commissioning, we provide independent senior technical oversight — drawing on direct operating experience at Meta, AWS, Microsoft, and Black & Veatch. We are not a replacement for your EPC or engineer of record. We are the specialist review layer that catches what generalist teams miss.
Independent QA and execution of arc flash, short-circuit, and coordination studies. Validation of relay settings, arc flash assumptions, and protection configurations against IEEE 1584, NFPA 70E, utility requirements, and owner-specific operating modes.
Pre-energization review, commissioning sequencing, and utility coordination for new data center builds and retrofits. Translating design packages into field-executable energization plans — with owner-side judgment on what can go wrong.
Root-cause analysis for electrical incidents, fleet-wide corrective action development, and condition-based maintenance strategy. Converting field failures into systemic improvements that raise uptime across your portfolio.
Power system advisory for high-density GPU compute infrastructure — harmonic behavior, protection coordination under variable load, BESS integration, and large-load utility interconnection planning for AI-scale deployments.
Hyperscalers may be the end-market. They are not always the first client. Arcline serves the broader ecosystem — the firms building, commissioning, financing, and operating hyperscale-grade infrastructure. If your team is exposed when something goes wrong on a high-voltage data center project, we are built for you.
Independent review of protection coordination, arc flash studies, commissioning risk, and utility interface assumptions before issues reach the owner. We help EPC teams de-risk deliverables — especially at the MV/HV boundary where most data center failures originate.
Hyperscale-grade electrical infrastructure advisory for teams expanding capacity, evaluating new sites, or preparing for energization — without needing a full internal power systems team. We bring the owner-side operational judgment that most consultants lack.
Senior MV/HV power-system support behind your commissioning program — relay setting validation, energization sequencing, UPS bypass planning, generator paralleling, and live-site cutover risk review. We are not a replacement for your Cx team. We are the technical layer that protects it.
Customer-side data center load expertise for large-load interconnections, power quality concerns, protection coordination alignment, and AI/GPU load behavior. We help utilities understand what hyperscale operators actually need — before and after the meter.
Technical due diligence on electrical capacity, reliability exposure, protection gaps, expansion readiness, and operational risk. We give infrastructure investors and owner's reps the same independent technical lens that hyperscale operators apply internally.
Senior QA/QC for SKM/ETAP models, arc flash scenario matrices, TCC reviews, and protection settings — calibrated to hyperscale architecture. We provide overflow review and independent validation for study vendors working on high-stakes data center programs.
Most advisory relationships start with a well-scoped, fixed-fee review. You get a clear deliverable. We get a clear line of sight into your risk. Below are the most common ways teams bring us in.
A 2–3 week fixed-fee review of your power system — designed to surface protection, arc flash, and commissioning risks before they become schedule delays, failed energizations, or safety exposures. Deliverable is an executive risk memo, findings matrix, and prioritized corrective actions.
Deliverable: Executive risk memo + technical findings matrix + top corrective actions. PE-stamped where required.
Pre-energization review of test scripts, relay settings, switching sequences, and outage risk. Designed to catch field exposure before energization day — for EPCs and Cx firms.
Independent QA of existing coordination studies, arc flash models, and scenario matrices. We review what was done, what was assumed, and what was missed — then deliver a gap findings report.
Customer-side review of utility interconnection packages, protection interface assumptions, large-load study inputs, and ERCOT-facing interconnection documentation for Texas data center projects.
Rapid RCA support for electrical events — SER and relay data analysis, failure mode assessment, corrective action development, and fleet-level lessons-learned documentation.
Independent electrical review for investors and owner's reps — one-line review, equipment basis-of-design, power capacity and expansion readiness, and electrical risk summary for decision-making.
We work on a project basis — no retainer lock-in. Engagements are scoped, fixed-fee where possible, and designed to deliver a clear, actionable deliverable. You get direct access to our senior engineers from day one.
A 30–60 minute call to understand your project, timeline, and what you need. No charge. We'll tell you directly if we're the right fit — and who to call if we're not.
A written proposal defining deliverables, timeline, and fee structure. Fixed-fee for well-defined reviews; T&M for ongoing advisory. Delivered within 3 business days.
Direct access to our senior engineers — not junior staff. Deliverables are PE-stamped where required and built to hold up under third-party and owner review.
Arcline brings together hyperscale owner-side perspective, EPC execution depth, and utility-grade power systems rigor. Our team has delivered, reviewed, operated, and optimized critical power infrastructure from the utility interconnection to the data hall — across AI/GPU deployments, colocation fleets, utility substations, protection studies, commissioning programs, and live-site reliability work.
Our team has worked inside hyperscale environments where electrical decisions are measured by uptime, deployable capacity, safety, commissioning readiness, and long-term operational risk. That experience shapes how we review SKM/ETAP models, protection settings, arc flash assumptions, GPU capacity constraints, live-site cutovers, and post-event corrective actions.
Arcline's team has produced and reviewed the engineering packages that drive real infrastructure delivery: one-lines, equipment specifications, relay settings, grounding studies, protection schemes, RFPs, construction packages, commissioning documents, and vendor submittals. We know where design intent gets lost between drawings, procurement, construction, testing, and operations.
AI-scale data centers increasingly depend on utility-grade engineering: high-voltage substations, large-load interconnections, transformer capacity, protection and control, grounding, insulation coordination, short-circuit duty, and transmission-level coordination. Arcline brings that substation and grid-interface discipline into the data center environment.
Data center power risk rarely lives in one drawing, one relay file, or one arc flash report. It lives in the gaps between utility assumptions, equipment ratings, operating modes, construction sequencing, commissioning constraints, protection settings, and real-world operating behavior. Arcline exists to close those gaps before they become failed energizations, unsafe assumptions, delayed schedules, or costly rework.
Arcline is led by Texas-licensed Professional Engineers with experience across hyperscale operators, cloud infrastructure owners, EPC delivery, utility substations, and mission-critical power systems. We bring owner-side judgment, design execution depth, and field-aware technical review to high-stakes electrical infrastructure decisions.

Practical perspectives on protection, commissioning, and reliability — written for the teams doing the work.
Most arc flash studies get done — but most get done wrong for hyperscale environments. Here are the three most common errors and why they matter when your systems are live.
Coming soonThe interface between your campus protection scheme and the utility's transmission system is where most large-scale failures originate. The coordination gaps EPCs consistently miss.
Coming soonMost reliability programs die after the first audit. This is how we've structured condition-based maintenance and PD trending programs that outlast the engagement.
