Every kilowatt engineered — Audit to Grid.

AVEX GRID is an independent Zimbabwean electrical engineering consultancy. We deliver energy audits, ETAP electrical studies, grid-code compliance, captive-solar design and bankable feasibility studies that get projects onto ZERA's IPP register — cutting ZESA bills and powering mines, industries and IPPs through Zimbabwe's energy transition.

02 What we do

Ten disciplines, built for ZERA & the Grid Code.

Aligned with the National Energy Efficiency Policy (NEEP 2025), ZERA's Energy Management Regulations, and the captive‑power directive. Two practices: technical engineering & grid forensics for the work on the wire, and strategic advisory & capital projects for the work that gets signed off by lenders and boards.

Practice 01

Technical Engineering & Grid Forensics

The on‑the‑wire engineering: audits, studies, models and stamped reports that hold up to ZERA inspection and lender due‑diligence.

01 · 01

Energy Auditing

Tiered audits — from walkthrough to investment‑grade — that turn waste into a bankable savings plan.

Turn Zimbabwe's 19% national energy waste into your most profitable virtual power plant.

With NEEP 2025 targeting 19% consumption savings and proposed legislation making audits mandatory for intensive users, waiting is a liability. We deliver a three‑tier audit — preliminary walkthrough, detailed assessment, and investment‑grade analysis — producing a bankable blueprint that typically cuts the electricity bill 30–40%.

  • Verified utility baselining to surface hidden production‑cycle losses.
  • Thermal imaging for ageing industrial infrastructure leaks.
  • IPMVP‑compliant M&V reporting for carbon credits or ZESA negotiations.

Power Quality Forensics

Harmonic, transient and flicker investigations behind the burnt VFDs and tripped relays.

Every load‑shedding cycle is a fresh insult to your motors, drives and transformers.

We instrument the supply with class‑A PQ analysers (Fluke 1770 / Dranetz), capture the disturbance before the next switchover, and produce an evidence pack you can take to ZESA, your insurer, or your switchgear supplier. Root‑cause every nuisance trip — not guess.

  • 7–30 day class‑A logging per IEC 61000‑4‑30, harmonic limits per IEEE 519.
  • Harmonic, transient, sag/swell and flicker characterisation.
  • Mitigation sizing — active filters, line reactors, K‑rated transformers.

Grid Code Compliance

Interconnection, anti‑islanding and ROCOF studies that get ZETDC to sign off.

The captive‑power directive turned every major plant into a micro‑grid. The Grid Code is no longer optional.

Every PV, BESS or DG plant connecting to ZETDC infrastructure must demonstrate compliance with the Zimbabwe Grid Code & Distribution Code. We deliver the full evidence package — protection settings, anti‑islanding, ROCOF, fault contribution and reactive‑power capability — in the format the utility expects.

  • ETAP‑modelled load flow, short circuit and motor starting.
  • Anti‑islanding & ROCOF coordination per IEEE 1547.
  • Stamped interconnection report ready for ZETDC submission.

Energy Efficiency

ECMs, VFDs and ISO 50001 readiness — payback before the next load‑shedding cycle.

With peak demand exceeding supply by roughly 700 MW, motors running flat‑out when 80% will do is a tax on profit.

We deploy VFDs, smart automation and ranked ECM portfolios that cut motor energy 20–60% — integrated with the Industrial Energy Efficiency Programme (IEEP) and ISO 50001 readiness for the coming certification of large consumers.

  • Immediate reduction in diesel backup costs during grid outages.
  • ECMs ranked by payback for clean CAPEX planning.
  • ISO 50001 EnMS framework ready for third‑party audit.

Electrical Engineering

Compliant, certified electrical design tuned to Zimbabwe's grid realities.

Stamped design that survives Hwange‑grade dirty power and karst‑terrain grounding.

As ZERA intensifies enforcement of the Electricity (Licensing) Regulations, non‑compliant installations risk penalties or full disconnection. We deliver end‑to‑end design and review tuned for Zimbabwean conditions — mining‑equipment harmonics, variable grid frequency, and the realities of importing certified equipment.

  • Mandatory electrical inspections with ZERA‑approved installer oversight.
  • Grid Code & Distribution Code compliance for legal operation.
  • ZWS / IEC‑certified equipment specifications.

Arc Flash & Protection Coordination

IEEE 1584 incident‑energy modelling and stamped relay coordination.

Engineered safety for plants that have just become micro‑grids.

Once a plant is generating its own power, every fault scenario changes. Stamped ETAP / SKM short‑circuit, arc‑flash and protection‑coordination studies are the first defence against equipment damage, regulator scrutiny and worker injury.

  • Load flow & short circuit — prevent oversized infrastructure that wastes CAPEX.
  • Arc flash per IEEE 1584 — legally defined PPE levels and approach boundaries.
  • Protection coordination — keep your solar array from blinding utility relays.

Strategic Advisory & Capital Projects

The work that gets a project financed, signed and built: bankable studies, owner‑side oversight, PPA structuring and the decarbonisation roadmap your board can defend.

02 · 01

Bankable Feasibility Studies

Techno‑economic models and yield assessments that DFIs and commercial lenders actually fund.

In Zimbabwe, finance is the first gate — not engineering.

DFIs (AfDB, IDC, World Bank) and commercial lenders demand a defensible techno‑economic model: P50/P90 yield, LCOE, sensitivity, DSCR and merchant‑risk analysis. We deliver the engineering side of the bankable pack — the part your financial advisor cannot fabricate.

  • P50/P90 PV & wind yield (PVsyst, satellite‑validated irradiance).
  • LCOE, NPV, IRR and DSCR sensitivity matrices.
  • Independent Engineer ready‑pack for lender's technical advisor.

PPA & Wheeling Architecture

Third‑party access structures aligned to ZERA's wheeling framework.

Wheeling is finally legal — and the deal structure is now the asset.

ZERA's wheeling framework — built on SI 86 of 2018 (Net Metering) and the 2026 Own‑Consumption Licensing & Energy Management Regulations — has unlocked third‑party PPAs across the national grid. We engineer the technical schedules (capacity, profile, take‑or‑pay, deemed‑generation, curtailment) that turn a one‑page intent letter into a contract a generator, off‑taker and ZETDC can all sign.

  • Generation & consumption profile modelling for capacity schedules.
  • Wheeling charge analysis under current ZETDC tariff methodology.
  • Curtailment, deemed‑energy and force‑majeure technical drafting.

Owner's Engineer Services

Independent oversight of EPC contractors — from spec to commissioning.

EPC contractors optimise for their margin. The Owner's Engineer optimises for your 25‑year LCOE.

Most Zimbabwean captive‑PV builds are turnkey EPCs from Chinese or Indian contractors, with MV switchgear imported from South Africa. We sit on your side of the table through tender adjudication, FAT/SAT witnessing in Shanghai or Mumbai, on‑site construction monitoring and provisional acceptance — protecting performance guarantees and catching variation orders before they hit your invoice.

  • EPC tender pack: SoW, technical schedules, BoQ, evaluation matrix.
  • Construction monitoring & non‑conformance reporting.
  • FAT, SAT & performance‑ratio testing per IEC 61724.

Asset Decarbonisation

Roadmaps that price carbon into the capex stack — for boards, lenders and off‑takers.

Export‑facing Zimbabwean producers are now priced against EU CBAM and ESG‑indexed capital.

We build a multi‑year decarbonisation roadmap that prices Scope 1 & 2 emissions into your capex stack — captive PV, BESS, fuel switching, process electrification and verified M&V. The output is what a sustainability‑linked lender or a tobacco / horticulture off‑taker wants to see.

  • GHG Protocol Scope 1 & 2 inventory, baseline year fixed.
  • Marginal abatement cost curve — ranked, dated, costed.
  • Sustainability‑linked KPI structure for SLL covenants.

05 About us

Senior engineers, real credentials.

Founded in 2025 by a qualified electrical engineer committed to raising the standard of power system design and energy consultancy in Zimbabwe.

AVEX GRID operates as a senior‑led consultancy — every project has at least one licensed P.E. on the model, the drawings, and the report. We don't subcontract the engineering.

Our reports are written to be read by the people who'll act on them: facility managers, plant electricians, controls vendors, insurers. Annotated, indexed, and reproducible in five years.

01

Stamped or not delivered

Every calculation set is reviewed and stamped by a licensed P.E. before release.

02

Measured, not modeled alone

Site data — sub‑meters, loggers, IR — anchors every recommendation.

03

Vendor‑independent

No equipment kickbacks. Specs are written for the facility, not the rep.

04

Document for posterity

Deliverables follow the practice's archival template — readable in 10 years.
