Deliver a viable, bankable mini-grid plan that balances engineering accuracy, commercial viability and real community benefit. At MzansiWriters.co.za we produce comprehensive feasibility studies for renewable mini-grids and distributed generation projects — written, modelled and validated by energy engineers, financial modellers and community engagement specialists.

What we deliver — bankable, action-ready studies
Our feasibility studies are tailored to investors, utilities, NGOs, municipalities and developers. Each study includes:
- Technical design and sizing for generation, storage and low-voltage networks.
- Detailed tariff modelling options with sensitivity and affordability analysis.
- Community impact assessment and stakeholder engagement plan.
- Financial model (Excel) with CAPEX/OPEX, cashflows, IRR and payback.
- Implementation roadmap and procurement recommendations.
- GIS maps, single-line diagrams and Bill of Quantities (BoQ).
- Clear executive summary and risk register for decision-makers.
Technical design: proven engineering, optimised performance
We design mini-grids that are safe, scalable and cost-effective. Our technical approach covers:
- Resource assessment (solar, wind, biomass, hydro).
- Load assessment (households, productive uses, seasonal variations).
- System architecture (AC vs DC, hybrid configurations).
- Battery sizing and lifecycle planning.
- Protection, control and metering strategies.
- Grid interconnection and islanding provisions.
Key technical components
- Generation: PV arrays, wind turbines, diesel gensets (as backup), biomass units.
- Storage: Lithium-ion or advanced lead alternatives with life-cycle cost analysis.
- Distribution: Overhead/underground LV network design, transformer siting.
- Controls: Energy management systems (EMS), SCADA and remote monitoring.
What we validate
- System losses and expected performance ratio.
- Battery degradation and replacement timeline.
- Safety compliance with local electrical standards.
- Scalability options for future demand growth or grid arrival.
Tariff models: fair, sustainable and flexible
Tariff design is central to mini-grid success. We build and compare multiple tariff models and quantify impacts on affordability, revenue stability and take-up.
- Flat tariffs for predictable billing and simple administration.
- Tiered tariffs (lifeline + commercial) to protect vulnerable consumers.
- Time-of-use tariffs to incentivise load shifting and manage peak demand.
- Prepayment systems to reduce non-payment risk and improve cashflow.
- Net-metering / wheeling where partial grid connectivity exists.
Tariff comparison
| Tariff Model | Pros | Cons | Best for |
|---|---|---|---|
| Flat tariff | Simple to administer; predictable revenue | May be regressive; low demand signals | Small communities with uniform demand |
| Tiered tariff | Protects low-users; progressive | More complex billing | Mixed-income communities |
| Time-of-use | Encourages efficient use; reduces peaks | Requires smart meters; behaviour change | Areas with flexible loads |
| Prepayment | Reduces collection risk; quick payments | Risk of disconnection for poorest | High non-payment environments |
| Net-metering | Enables exports and prosumers | Requires interconnection rules | Areas near the main grid |
We model each option in a dynamic financial model with sensitivity runs for solar yield, demand growth, CAPEX escalation and collection rates.
Community impact: social, economic and environmental outcomes
A technically sound mini-grid must also benefit the community. Our community impact work is evidence-based and participatory.
- Conduct baseline socio-economic surveys and needs assessments.
- Map productive uses (agriculture processing, small enterprises, health and education).
- Assess gender and inclusion impacts and propose mitigation/enhancement measures.
- Quantify job creation potential (construction, operations, entrepreneurship).
- Evaluate environmental impacts and propose safeguards (waste battery management, land use).
- Create stakeholder engagement and benefit-sharing plans.
Community acceptance is measured and reported with recommendations to increase adoption and reduce social risk.
Our process: clear milestones, transparent deliverables
We follow a structured, transparent workflow to deliver studies on time and within budget.
- Phase 1 — Desktop review and preliminary scoping (2 weeks)
- Phase 2 — Site visits, resource measurement and community engagement (2–4 weeks)
- Phase 3 — Technical design, tariffs and financial modelling (3–4 weeks)
- Phase 4 — Report finalisation, GIS outputs and procurement package (1–2 weeks)
Each phase includes stakeholder workshops and draft review cycles. Typical total delivery time: 6–12 weeks, depending on scope and site accessibility.
Deliverables & formats
We deliver materials ready for investors and implementers:
- Full written feasibility report (PDF) with executive summary.
- Financial model (Excel) with scenarios and sensitivity analysis.
- Engineering drawings: single-line diagrams, layout plans (PDF/DWG).
- GIS layers and site maps (shapefile/KML).
- Procurement-ready BoQ and scope of work.
- Stakeholder engagement and gender action plan.
Pricing packages (indicative)
We price to match the complexity of your project. Final quotes follow a scoping call.
| Package | Scope | Typical turnaround | Indicative price (ZAR) |
|---|---|---|---|
| Basic | Desktop study, preliminary sizing, high-level tariff options | 2–3 weeks | 40,000–80,000 |
| Standard | Full site survey, detailed technical design, tariff modelling, Excel financial model | 6–8 weeks | 120,000–250,000 |
| Comprehensive | All standard items + community impact study, GIS, procurement pack, investor-ready report | 8–12 weeks | 260,000–480,000 |
Prices vary with site remoteness, number of villages, and data collection complexity. We provide fixed-price proposals after scoping.
