Solvanta Renewables Business Plan › Section 12 › Technology Infrastructure

Generation and storage technologies

• Solar PV: n-type bifacial modules on single-axis
  trackers; DC/AC ratios 1.25–1.35; string inverters for O&M
  simplicity on distributed sites, central inverters on 100 MW+
  blocks.
• Wind: 5.5–6.5 MW class turbines on 120–140 m hub
  heights, matched to SA wind corridor profiles; full-scope OEM service
  agreements for the first 10 years.
• BESS: Containerised LFP systems at 2–4 hour
  durations; augmentation-based capacity maintenance contracts;
  grid-forming inverter capability for ancillary service
  eligibility.
• Hybrid control: Plant-level power plant
  controllers coordinating solar, wind and BESS dispatch against
  contracted delivery profiles and TradeCo’s balancing positions.

Digital platform

The commercial differentiation of the wheeling and FlexPower products
depends on an energy data platform performing three functions: metering
and settlement (half-hourly reconciliation of generation, wheeling
losses and consumption across every customer meter, integrated with
Eskom/NTCSA and municipal wheeling frameworks); forecasting (AI-based
generation and load forecasting driving day-ahead trading positions and
BESS dispatch, forecast accuracy directly converts to balancing cost
avoided); and customer transparency (portals providing real-time
delivered-energy, savings and carbon accounting per site, supporting
customers’ scope 2 reporting and CBAM documentation). The platform is
built on commercial energy-trading and asset-management software
configured in-house, with an estimated R120 million cumulative
investment through FY2029 included in development capex.

Technology risk posture

All deployed technologies are proven at global scale, no technology
development risk is taken. Vendor risk is managed through tier-1
procurement, dual-vendor frameworks and OEM performance guarantees.
Cybersecurity follows IEC 62443 for operational technology, with the
trading and settlement platform subject to financial-grade controls; a
dedicated security operations budget is carried in ServCo opex.
