Theme: Electricity regulation / tariffs
Assessment

Feasibility Assessment
Medium: NERSANERSA — National Energy Regulator of South Africa: The regulatory authority for the electricity, piped-gas, and petroleum pipelines industries in South Africa. NERSA approves Eskom's tariff applications and licenses new electricity generators. has guideline-setting powers but enforcement is limited. Municipalities guard tariff autonomy under the Constitution. Requires COGTA-NERSA coordination framework with legislative backing.

Treasury supports cost-reflective municipal tariffs as non-cost-reflective pricing creates hidden fiscal liabilities.

Description
South Africa's electricity tariff structure is fragmented across EskomEskom: South Africa's national electricity utility and dominant power producer, transmitter, and distributor. Eskom's debt crisis and maintenance failures have been a primary cause of load shedding and a binding constraint on economic growth. 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.

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.
Amend Electricity Regulation Act Section 15 to give NERSA explicit binding authority to approve, reject, or cap municipal electricity tariffs; eliminate the current advisory-only guideline regime
