Treasury supports cost-reflective municipal tariffs as non-cost-reflective pricing creates hidden fiscal liabilities.
Interest: Fiscal consolidation with public debt stabilising below 75% of GDP; structural reforms that improve revenue without expanding contingent liabilities;…
Concern: Unfunded mandates in energy transition (JETP co-financing); Eskom's R400bn+ debt and how restructuring socialises costs; reform proposals that create…
Engagement path: Reforms must be fiscally neutral or revenue-positive over the MTEF window; SOE restructuring must demonstrably reduce contingent liabilities; credible…
Eskom supports cost-reflective municipal tariffs as non-cost-reflective tariffs create revenue shortfalls that undermine grid investment.
Interest: Managing R400bn+ debt restructuring with government support; maintaining grid stability during the unbundling transition; preserving technical and ins…

Municipal tariff rationalisation and cost-reflective pricing is core NERSA regulatory mandate.

South Africa's electricity tariff structure is fragmented across Eskom bulk supply and approximately 160 municipal distributors, with municipal tariffs varying widely and often lacking cost-reflective design. NERSA's approval process under the MFMA has historically been weak in enforcing cost-reflectivity, enabling cross-subsidisation of rates income from electricity margins. The reform involves NERSA developing standardised tariff methodologies for municipalities, enforcing ring-fenced electricity accounts, and introducing time-of-use pricing aligned with Eskom's Megaflex tariff structure. Cost-reflective tariffs are essential for rooftop solar economics, demand response, and private distribution investment. Several municipalities — including Ekurhuleni and eThekwini — face electricity distribution entity (EDE) viability questions. As of early 2026, NERSA's municipal tariff review process has been initiated but standardisation is nascent and politically contested in councils dependent on electricity revenue surpluses.
Referenced in OECD Economic Surveys: South Africa
OECD SA Survey (2017, 2020, 2022, 2025). Consistently recommended as key structural reform; the 2025 survey estimates pro-competition reforms including energy could add ~4.5pp to GDP over 10 years.
Industrial users leaving the municipal grid to escape punitive tariffs take their cross-subsidy with them — tariff rationalisation is urgent before the spiral worsens. — NERSA Electricity Distribution Industry Task Team, 2024
Municipal electricity distributors — responsible for approximately 40% of South Africa's electricity distribution — operate with widely diverging tariff structures that cross-subsidise from industrial to residential consumers and suppress demand-side investment. NERSA's Municipal Tariff Guidelines set a framework but enforcement is limited, with many municipalities filing non-compliant tariffs or failing to file altogether. The reform establishes NERSA's binding authority over municipal electricity tariffs, mandates cost-reflective pricing aligned with the national tariff framework, and introduces a three-year rationalisation path for municipalities with unsustainable cross-subsidy structures. Coordination with the Electricity Distribution Industry Restructuring process managed by COGTA is essential.

Implement a Municipal Electricity Audit programme: annual NERSA inspections of metering infrastructure, non-technical loss rates, and tariff compliance; publish results in an Annual Municipal Tariff Report
Establish a Municipal Distribution Infrastructure Grant through National Treasury to fund metering upgrades and loss-reduction investments in municipalities transitioning to cost-reflective tariffs
18 months for legislative amendment and framework (Q1 2025–Q3 2026); three-year rationalisation path for municipalities (2026–2029)
NERSA cost-of-supply studies: ~R150 million over two years (funded by licensee levy). Municipal Distribution Infrastructure Grant: R2–5 billion over MTEF. NERSA capacity expansion for audit function: R80 million/year.
Amendment to Electricity Regulation Act 4 of 2006 (Section 15) converting NERSA municipal tariff guidelines from advisory to binding. The ERA Amendment Act (2024) may require a targeted further amendment to close the binding authority gap on municipal tariffs.
Municipal tariff reform faces resistance from metro governments (City of Cape Town, Ekurhuleni, eThekwini) who derive cross-subsidy revenue from industrial customers. ANC-controlled municipalities are ambivalent. National Treasury supports reform for fiscal sustainability. The COGTA Section 154 intervention mechanism is the backstop for non-compliant municipalities but is politically costly to invoke.
The UK's Ofgem RIIO distribution price control framework is the benchmark for binding regulatory tariff determination with cost-of-service methodology. Australia's AEMC distribution determination framework provides a comparable model for cost-reflective pricing transition. Botswana's BPC single national tariff framework offers an African precedent for rationalisation at scale.
