NERSA Tariff Compliance Analysis

This dashboard illustrates the critical disconnect between the Bulk Supply Cost from Eskom and the NERSA-approved Distribution Tariffs. As per NERSA regulations, municipalities should generate a 60% gross profit margin on electricity distribution to fund infrastructure maintenance and service delivery obligations.

Executive Summary

The DBNLM Bulk Account Status Quo

Dr. Beyers Naudé Local Municipality faces a systemic institutional challenge that threatens its ability to fulfill constitutional service delivery mandates — not due to administrative failure, but due to structural tariff misalignment beyond municipal control.

The Problem Statement
Structural tariff misalignment creating institutional crisis

NERSA-approved Distribution Tariffs are designed to generate a 60% gross profit margin on electricity trading — a margin essential for municipalities to fund infrastructure maintenance, operational costs, and cross-subsidize other essential services.

Current Gross Profit
19.6%
40.4 points below target
NERSA Target
60%
Required for sustainability
Current Bulk Cost
R10.1M/mo
Target: R4.0M/mo

Constitutional Mandate at Risk

  • Service Delivery: Electricity collections cannot cover electricity expenditure, let alone support other services
  • Inter-Service Cross-Subsidization: Monthly shortfall of R33.6M across Water, Refuse, Sewerage and Other services historically dependent on electricity surplus
  • Credit Control Paralysis: Eskom distribution areas prevent DBNLM from implementing credit control via prepaid electricity blocking
The Solution Hypothesis
My SSEG DBNLM — A replicable national model for municipal financial recovery

The My SSEG DBNLM initiative proposes a sustainable, technology-driven intervention that addresses the root cause of the tariff disconnect through strategic energy asset deployment:

BESS Deployment
121.94 MWh Battery Storage
  • • Tariff arbitrage: Charge off-peak, discharge peak
  • • Virtual Wheeling: Eskom credits against debt
  • • First national debt-recovery-by-energy model
  • • Across 6 towns in DBNLM
PV Distributed Generation
137.61 MWp Planned Capacity
  • • Reduce Eskom bulk dependency by 60%
  • • Generate new gross profit to cover asset costs
  • • Achieve NERSA-compliant 60% gross margin
  • • Optimal BESS:PV ratio of 1.13:1

Target Outcome

Transform current bulk supply cost from R10.1M/month to a blended cost of R4.0M/month — achieving the 60% gross profit margin prescribed by NERSA for sustainable municipal electricity trading.

The Key Asks
Concessions required to achieve normalization
Normalization Target
Gross Profit = 60% or equivalently Bulk Supply ≤ R4.0M/month
1

Debt Suspense Account Concession

Authorization for DBNLM to place historical Eskom debt in a Suspense Account, enabling debt reduction through proceeds generated from the municipality's sale of stored BESS energy under the Eskom Virtual Wheeling program.

Estimated Monthly Debt Recovery
R1.8M/month
Via Virtual Wheeling credits against suspense account
2

9-Month Grace Window

A 9-month implementation window for DBNLM to complete deployment of all planned PV Distributed Energy Resources, allowing the municipality to achieve the required bulk supply cost reduction.

Planned PV Deployment
137.61 MWp Total Capacity
Distributed across 6 towns

Expected Outcome Upon Approval

  • Bulk supply cost reduced from R10M to R4M/month (60% reduction)
  • Gross profit margin aligned with NERSA 60% target
  • Historical debt systematically reduced through energy credits
  • Constitutional service delivery mandate restored
  • First replicable national model for municipal financial recovery
