De-risked by design

Where the risk sits — and how it is removed

Every conventional objection to a metering programme is answered by the structure of the UtCS engagement, not by a promise.

Capital exposure on the metering rollout

BMM would traditionally fund R17.9m of metering infrastructure up front.

Mitigation: UtCS finances 100% of the CAPEX. BMM commits no capital — the infrastructure is recovered through the Phase 1 service fee over approximately 11 months.

Uncertain return on investment

Efficiency programmes often promise savings that never materialise.

Mitigation: The commercial model is cost-avoidance based: BMM only pays a percentage of verified avoided cost, so savings are structurally guaranteed before any fee applies.

Operational & maintenance burden

In-house metering demands specialist skills, vending systems and 24/7 support.

Mitigation: UtCS operates the prepaid vending platform, maintains all 1,920 meters and manages resident collections for the full Phase 1 term.

Optimisation figures are indicative

NMD and water-balancing savings depend on post-deployment load profiles.

Mitigation: Phase 2 optimisation targets are presented as indicative and confirmed against live data before commitment. The signed proposal prevails in any discrepancy.

Assurance & governance

Compliance, confidentiality & source integrity

This is a decision-grade document. The figures are traceable, the assumptions are stated, and the contractual instrument remains authoritative.

STS-compliant prepaid metering

All electricity meters conform to the Standard Transfer Specification, ensuring interoperable, tamper-evident prepaid vending.

Contractual figures prevail

Every figure in this portal is drawn from the signed technical & commercial proposal. Executed contractual documentation governs in any discrepancy.

Source notes & assumptions

  1. 1Capital recovery is described as approximately 11 months in line with the annuity model (6.5% p.a. cost of capital).
  2. 2Phase 2 commences following the successful CAPEX-recovery and asset-transfer milestone; the source references differing month boundaries, so no single boundary is presented as definitive.
  3. 3NMD and water-balancing figures are indicative and dependent on post-deployment profile analysis.
  4. 4In the event of any discrepancy, the signed technical & commercial proposal and executed contractual documentation shall prevail.
