SOCIAL LEGITIMACY OF ELECTRICITY MARKETS

1. Meaning and Concept

Social legitimacy of electricity markets refers to the degree to which consumers, communities, businesses and wider society regard the organisation, regulation and outcomes of the electricity sector as fair, acceptable, transparent and justified. Electricity markets cannot operate sustainably merely because their rules are legally valid or economically efficient. They must also maintain public confidence, particularly because electricity is an essential service affecting housing, health, education, employment and economic participation.

Legitimacy therefore connects electricity-market regulation with affordability, procedural fairness, transparency, public participation, environmental sustainability and distributive justice.

2. Legal Foundations of Market Legitimacy

In South Africa, legitimacy is strongly connected with constitutional and administrative-law principles. The Electricity Regulation Act 4 of 2006 requires regulation to safeguard present and future customers, facilitate universal access and establish a fair balance between consumers, licensees, investors and the public. In NERSA v Borbet, the Supreme Court of Appeal emphasised that tariff regulation operates within this statutory framework and affects households and businesses throughout society.

Social legitimacy consequently requires regulators such as NERSA to demonstrate that electricity pricing and market decisions are based upon lawful procedures, relevant evidence and rational regulatory objectives.

3. Procedural Legitimacy

Citizens are more likely to accept difficult electricity decisions—including tariff increases, infrastructure development or disconnections—where decision-making processes are transparent and procedurally fair.

Case Name/Citation

Joseph and Others v City of Johannesburg and Others (CCT 43/09) [2009] ZACC 30; 2010 (4) SA 55 (CC).

Facts: Tenants at Ennerdale Mansions had their electricity disconnected because their landlord owed substantial amounts to City Power, even though the tenants had generally paid their electricity charges to the landlord.

Legal Issue: Whether persons without a direct contractual relationship with City Power were entitled to procedural fairness before electricity was disconnected.

Judgment: The Constitutional Court held that the disconnection was unlawful and recognised that electricity is an important basic municipal service. Affected residents were entitled to procedural fairness and notice.

Legal Principle/Ratio: Public electricity provision creates public-law responsibilities extending beyond narrow contractual relationships.

Significance: The case demonstrates that electricity-sector legitimacy depends upon treating affected consumers as rights-bearing participants rather than merely market customers.

4. Tariff Fairness and Regulatory Accountability

Case Name/Citation

National Energy Regulator of South Africa v Borbet SA (Pty) Ltd [2017] ZASCA 87.

Facts: Businesses challenged NERSA's approval of an additional electricity tariff increase granted to Eskom.

Legal Issue: Whether NERSA's tariff determination constituted reviewable administrative action and whether the regulatory process complied with applicable requirements.

Judgment: The Supreme Court of Appeal confirmed that NERSA's tariff determination constituted administrative action subject to judicial scrutiny, while ultimately upholding the appeal and dismissing the challenge to the determination.

Legal Principle/Ratio: Specialist economic regulation receives appropriate judicial respect, but regulatory decisions are not immune from legality, rationality and administrative-law review.

Significance: Market legitimacy requires a credible independent regulator capable of balancing utility sustainability, investment requirements and protection of consumers.

5. Environmental and Intergenerational Legitimacy

Electricity markets also require legitimacy concerning environmental consequences. Communities increasingly expect generation and investment decisions to account for climate risks and future generations.

Case Name/Citation

Earthlife Africa Johannesburg v Minister of Environmental Affairs (65662/16) [2017] ZAGPPHC 58.

Facts: Environmental authorisation had been granted for the proposed Thabametsi coal-fired power station without comprehensive prior assessment of its climate impacts.

Legal Issue: Whether climate-change impacts had to be properly considered within the environmental authorisation process.

Judgment: The High Court set aside the Minister's appeal decision and required reconsideration incorporating a climate-change impact assessment and public comments.

Legal Principle/Ratio: Relevant climate impacts must form part of lawful environmental decision-making where required by the statutory framework.

Significance: Electricity-market legitimacy extends beyond price and reliability to environmental accountability and meaningful participation.

6. Conclusion

Social legitimacy is therefore a governance condition for durable electricity markets. A legitimate market combines economic efficiency with affordability, transparency, participation, procedural fairness, environmental responsibility and effective regulatory oversight. Courts reinforce this legitimacy by ensuring that electricity institutions exercise public power lawfully and rationally. Consequently, electricity-market reform should not measure success solely through competition, investment or technical efficiency; it should also examine whether market institutions retain the confidence and acceptance of the society they serve.
