Our Electrical Infrastructure Services
We organize our electrical infrastructure work into nine integrated workstreams covering strategy, utility coordination, network and substation design, SCADA/EMS, contracting, financing and project execution. Most clients engage us across multiple workstreams to maintain consistency between design, contracting and energization.
Development, Feasibility & Electrical Infrastructure Strategy
Strategic electrical planning — done early — prevents the most expensive surprises in a development: insufficient supply capacity, mismatched voltage levels, late utility approvals and unnecessary infrastructure cost. Our strategy work establishes the right framework before detailed design begins.
- Existing electrical supply assessment
- Load assessment and demand forecasting
- Electrical master planning for large-scale developments
- Voltage level selection and supply strategy
- Utility connection strategy and point of supply identification
- MV / LV / HV infrastructure planning where applicable
- Internal distribution network strategy
- Phased implementation and energization strategy
- Future expansion and load growth planning
- CAPEX / OPEX benchmarking
- Early-stage risk assessment covering technical, utility, permitting, routing, cost and energization risks
Utility Connection & Grid Interface Management
Coordinating with utilities is one of the most under-resourced parts of many developments. Our team manages the utility-facing process end to end — from initial application to energization clearance freeing up the client’s internal team and accelerating approvals.
- Utility connection application support
- Point of connection / point of supply assessment
- Coordination with utility, grid operator and relevant authorities
- Utility technical requirement review
- Connection capacity assessment
- Metering and service connection coordination
- Right-of-way, route and corridor coordination
- Permit and NOC support where required
- Connection agreement technical support
- Energization sequence planning and interface management between client, utility, contractor and authorities
Transmission & Distribution Network Planning
We design transmission and distribution networks that meet today’s load and accommodate tomorrow’s growth, with appropriate redundancy, voltage regulation and operational flexibility built in from the start.
- MV distribution network planning
- LV distribution network planning
- HV / EHV interface planning where applicable
- Underground cable network planning
- Overhead line routing and network planning where applicable
- Ring, radial and open-loop network configuration
- Main feeder and sub-feeder arrangement
- Distribution transformer placement strategy
- RMU, feeder pillar and distribution board allocation
- Redundancy and reliability planning, including N-1 assessment where required
- Voltage regulation and power quality planning
- Network expansion provisions, operational continuity and load transfer strategy
Power System Studies & Technical Analysis
Our electrical infrastructure designs are validated through structured power system studies — ensuring equipment is correctly rated, protection is properly coordinated and the network behaves as expected under all operating conditions.
- Load flow analysis
- Voltage drop studies
- Short-circuit studies and equipment rating validation
- Protection coordination and selectivity studies
- Transformer loading studies
- Cable ampacity and thermal rating studies
- Motor starting studies for pumps, compressors and large process loads
- Reactive power and power factor correction studies
- Harmonic and power quality assessment
- Earthing system studies, including step voltage and touch voltage assessment
- Arc flash assessment where required
- Reliability and redundancy analysis
- Insulation coordination studies where required
- Network modelling using ETAP / DigSILENT
T&D Network, Substation & Facility Design
We deliver detailed design for substations, distribution networks and facility electrification — producing the IFC-grade documentation that contractors need to build, and authorities need to approve.
- MV / LV distribution network design
- HV interface design where applicable
- Underground cable and overhead line design
- Ring, radial and open-loop network configuration
- Primary and secondary substation design
- Transformer, switchgear, RMU and LV panel specification
- Cable routing, trenching and duct bank design
- Earthing and lightning protection design
- Facility electrification design for agricultural, industrial, commercial and private developments
- Power supply design for pumping stations, motor loads, cold storage, warehouses and support facilities
- Emergency, backup power and load-shedding strategy where required
- Technical specifications, design basis and IFC package preparation
SCADA / EMS & Metering
Modern electrical infrastructure depends on monitoring, control and metering systems that are correctly architected from day one. We specify SCADA, EMS and metering systems that integrate cleanly with utility requirements and the client’s operational needs.
SCADA / EMS architecture
- SCADA, RTU and communication system requirements
- EMS communication system requirements
- Utility metering, revenue metering and check metering coordination
Tendering, Procurement & Contractual Support
Electrical infrastructure tenders are technically dense and easily mis-priced if specifications are unclear. We prepare tender documents, design tender drawings and evaluate bids with the rigour these contracts require.
- RFP and Employer’s Requirements preparation
- Technical specifications and BOQ development
- Tender drawing package preparation
- Bidder prequalification and tender management
- Technical and commercial bid evaluation
- Approved vendor and material review and long-lead equipment identification
- FAT / SAT requirements definition
- EPC or multi-package procurement strategy
- Responsibility matrix between client, utility, EPC, OEMs and authorities
- Definition of technical performance requirements covering capacity, reliability, voltage quality, losses, redundancy and energization milestones
- Testing, commissioning and acceptance criteria definition
- Utility approval, delay and energization risk allocation
Financial, Loan, Tax & Project Funding Support
Electrical infrastructure is a major capital expenditure on most developments — and increasingly something lenders, government funds and infrastructure investors are willing to finance. We help clients structure that financing.
- Infrastructure CAPEX and OPEX modelling
Project cost breakdown by scope:
- Utility connection
- Substations
- MV / LV networks
- Cables and overhead lines
- Facility electrification
- Protection, SCADA and metering
- Testing and energization
- Cash-flow forecasting and cost-to-complete analysis
- Lifecycle cost assessment
- Grid electrification cost-benefit analysis
- Existing self-generation or temporary power replacement savings assessment where applicable
- Financial sensitivity analysis covering load growth, equipment cost, connection cost, exchange rate, interest rate and project delays
- Funding requirement assessment, debt and equity structuring support
- Loan application technical and financial input preparation
- Commercial bank, development finance, infrastructure fund, government fund, supplier or vendor financing support where applicable
- Lender due-diligence coordination
- Financial close roadmap and conditions precedent tracking
- VAT / GST, corporate tax, withholding tax and customs duty impact assessment
- Asset depreciation and capital allowance review
- Coordination with tax advisors, auditors and legal counsel
