Power, Grid Interface & Resilience

Grid Interconnection & Feasibility

Site-specific grid capacity and timeline analysis — the single most consequential input to most AI-DC programmes right now
Utility engagement strategy and interconnection agreement negotiation support
Contracted capacity sizing against near-term build and long-term expansion envelope; avoiding the dual failure mode of under-sizing (future constraint) and over-sizing (stranded capacity and reservation charges)
Alternative-supply feasibility: second utility feed, on-site generation, behind-the-meter renewables, storage co-location, and Power Purchase Agreement (PPA) structuring
Load-flow and short-circuit modelling at the point of common coupling
Power-quality assessment and harmonic-compliance strategy (IEEE 519) against utility and regulatory obligations

Medium-voltage topology review: ring, radial, primary-secondary selective; switchgear rating, protection, and selectivity study
Transformer selection and sizing; loss profile, efficiency class, and harmonic tolerance for modern GPU workloads
Low-voltage distribution architecture: busway vs cable, redundancy topology (N, N+1, 2N, 2(N+1)), concurrent-maintainability review
Fault-current and arc-flash analysis; IEC 61439 assembly verification; protection coordination and discrimination
Grounding, bonding, and EMC design review (IEEE 1100 / IEC 62305) — material for GPU-dense halls where harmonics and transient behaviour are elevated

UPS topology selection: static double-conversion, rotary/diesel-rotary, hybrid, modular scalable — against load profile, efficiency economics, and maintainability
Battery technology evaluation: VRLA, Li-ion (LFP, NMC), flow, flywheel — with fire-protection, containment, and end-of-life implications explicitly modelled
Energy-storage sizing and runtime design tied to generator-start confidence, grid-support obligations, and operational-recovery profile
Harmonic impact and input filtering for UPS banks under GPU-transient load conditions
Eco-mode, Energy Storage System (ESS) integration, and grid-services participation strategy where commercially and regulatorily relevant

Generator sizing, topology, and redundancy — synchronous parallel, isolated, or isochronous-bus configurations
Prime-mover selection: diesel, gas, dual-fuel, HVO (hydrotreated vegetable oil), and hydrogen-ready architectures; engineered against fuel availability, regulatory trajectory, and owner sustainability commitments
Fuel storage, polishing, and logistics; bunded tank design, spill containment, and environmental permitting
Emissions compliance: EU IED (Industrial Emissions Directive), MCPD (Medium Combustion Plant Directive), Stage V, and national/regional permits
Starting-reliability engineering: black-start sequences, load-acceptance, governor tuning, and retained-maintenance protocols

Factory acceptance test (FAT) and site acceptance test (SAT) witnessing for switchgear, UPS, transformers, and generator sets
Integrated electrical-system commissioning: protection testing, selectivity demonstration, load-bank testing at full envelope
Pull-the-plug and black-start demonstrations
Redundancy and concurrent-maintainability validation; every redundant path proven under load
Eco-mode, Energy Storage System (ESS) integration, and grid-services participation strategy where commercially and regulatorily relevant
Operational-readiness review: spares, service contracts, operator training, runbooks

PUE attribution analysis — electrical losses isolated from thermal, IT, and parasitic loads
UPS efficiency-profile review against operating load factor; eco-mode and modular-scaling decisions revisited annually
Generator reliability analytics: start confidence, runtime hours, maintenance-to-load correlation
Emissions compliance: EU IED (Industrial Emissions Directive), MCPD (Medium Combustion Plant Directive), Stage V, and national/regional permits
Harmonic and power-quality drift monitoring under evolving workload mix
