Description

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.

Assessment

Growth Impact4/5

Feasibility Assessment

Medium: NERSA has guideline-setting powers but enforcement is limited. Municipalities guard tariff autonomy under the Constitution. Requires COGTA-NERSA coordination framework with legislative backing.

OECD

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

Implementation Roadmap

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.

Q3 2025–Q1 2026 (budget process)National Treasury / NERSA / COGTA
Timeline

18 months for legislative amendment and framework (Q1 2025–Q3 2026); three-year rationalisation path for municipalities (2026–2029)

Estimated Cost

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.

Required Legislation

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.

Political Feasibility

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.

International Precedents

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.
