Competition Law and Self-Regulating Market Ecosystems

1. Meaning and Concept

The concept of electricity as a legal public good recognises that electricity is not merely an ordinary commercial commodity. Modern societies depend upon electricity for housing, healthcare, education, communication, industry, public safety and economic development. Consequently, legal systems increasingly regulate electricity supply in accordance with public-interest obligations, even where generation or distribution is performed by private or corporatised entities.

Economically, electricity does not perfectly satisfy the classical definition of a “public good,” because access can be restricted and consumption must be paid for. Legally, however, describing electricity as a public good emphasises its essential public-service character. Electricity regulation therefore seeks to reconcile commercial sustainability with accessibility, affordability, reliability, equality and security of supply.

The South African Constitutional Court has specifically recognised electricity as an important basic municipal service that has become virtually indispensable, particularly in urban society.

2. Constitutional and Public-Law Foundation

Although the Constitution of the Republic of South Africa, 1996 does not expressly establish a standalone constitutional right to electricity comparable to the right of access to sufficient water, electricity provision is connected with constitutional values including human dignity, adequate housing, equality and socio-economic development.

Sections 152 and 153 of the Constitution establish important developmental and service-delivery responsibilities for municipalities. These principles are reinforced by the Local Government: Municipal Systems Act 32 of 2000. Section 73 requires municipalities to prioritise basic community needs and ensure access to at least a minimum level of basic municipal services.

Accordingly, electricity acquires a public-law dimension because government institutions cannot treat its provision purely as a private contractual transaction.

3. Public Good and Regulatory Control

Electricity's public-good character justifies extensive regulation of generation, transmission, distribution, tariffs, licensing, grid access and service quality. Regulation attempts to prevent electricity infrastructure from being managed exclusively according to private commercial interests where doing so would undermine broader societal welfare.

This approach can also be seen comparatively. In 2025, the Supreme Court of India expressly stated that “Electricity is a public good and is regulated under the Act.” The Court connected electricity regulation with the common good and explained that electricity tariffs are determined through the statutory regulatory framework rather than ordinary market forces alone.

4. Case Law – Joseph and Others v City of Johannesburg and Others

Case Name/Citation

Joseph and Others v City of Johannesburg and Others [2009] ZACC 30; 2010 (4) SA 55 (CC).

Facts

Tenants living in Ennerdale Mansions had their electricity disconnected because the landlord accumulated substantial arrears owed to City Power. The tenants themselves had no direct contractual relationship with City Power.

Legal Issue

The Constitutional Court considered whether occupants without a direct electricity contract nevertheless possessed public-law rights requiring procedural fairness before disconnection.

Judgment

The Court held that electricity was supplied pursuant to the constitutional and statutory responsibilities of local government. The tenants therefore received electricity through a corresponding public-law right, and City Power was required to provide procedural fairness before terminating supply.

Legal Principle/Ratio

Electricity is an important basic municipal service, and municipalities have public duties concerning its provision. The legal relationship between electricity users and public suppliers therefore extends beyond ordinary contract law.

Significance

Joseph provides strong authority for understanding electricity as a service possessing a public-good and public-law character. It demonstrates that electricity disconnection may engage administrative-law protections even where contractual privity is absent.

5. Case Law – Eskom Holdings SOC Ltd v Emfuleni Local Municipality

Case Name/Citation

Eskom Holdings SOC Limited v Emfuleni Local Municipality and Others [2023] ZAGPPHC 497.

Facts

The dispute concerned electricity supply and municipal obligations in circumstances affecting consumers and economic activity within the municipality.

Legal Issue

The Court considered the legal significance of municipal electricity obligations and the regulatory framework governing electricity distribution.

Judgment

The Court reaffirmed the principle from Joseph that electricity is an important basic municipal service. It also emphasised the connection between reliable electricity provision and the constitutional objective of promoting social and economic development.

Legal Principle/Ratio

Electricity distribution carries statutory and public responsibilities that cannot be reduced to ordinary commercial supply arrangements.

Significance

The decision illustrates how electricity's public-service character extends beyond household consumption and affects industry, employment and economic development.

6. Legal Consequences of Treating Electricity as a Public Good

Recognising electricity as a legal public good supports obligations relating to universal access, reasonable tariffs, continuity of supply, procedural fairness, non-discrimination and regulatory accountability. Nevertheless, the concept does not mean electricity must always be supplied free of charge. Courts recognise that municipalities and electricity utilities must remain financially sustainable and may legitimately collect unpaid debts.

7. Conclusion

Electricity as a legal public good represents the transformation of electricity from a purely market commodity into an essential regulated public service. Its indispensable role in human dignity, housing, economic activity and social development justifies extensive public regulation. Cases such as Joseph and Eskom v Emfuleni demonstrate that electricity provision creates significant public-law duties concerning accessibility, fairness and continuity. The concept therefore balances individual access, collective welfare, regulatory accountability and the financial sustainability of the electricity system.
