206. CONSTITUTIONAL DUTIES OF ENERGY REGULATORS

1. Introduction

Energy regulators occupy a constitutionally important position because electricity, energy security, tariffs, environmental protection and access to essential services directly affect the public. In South Africa, the National Energy Regulator of South Africa (NERSA) exercises statutory powers within a constitutional framework. Its decisions must therefore comply not only with the Electricity Regulation Act 4 of 2006, but also with constitutional values such as lawfulness, accountability, transparency, rationality, public participation, equality and the rule of law.

The constitutional duty of an energy regulator is consequently broader than merely approving tariffs or issuing licences. A regulator must exercise its technical discretion in a manner consistent with constitutional rights and administrative justice.

2. Constitutional Foundation

Section 7(2) of the Constitution requires the State to respect, protect, promote and fulfil the rights in the Bill of Rights. Section 33 guarantees lawful, reasonable and procedurally fair administrative action and requires written reasons where rights are adversely affected. Section 195 establishes principles of accountable, transparent and responsive public administration, while section 237 requires constitutional obligations to be performed diligently and without delay.

Energy regulators must therefore:

exercise statutory powers lawfully and rationally;

provide meaningful public participation;

disclose sufficient information for informed participation;

give adequate reasons for important regulatory decisions;

consider relevant constitutional and socioeconomic consequences;

act within reasonable statutory and constitutional timeframes; and

remain accountable despite possessing specialised technical expertise.

3. Major Constitutional Duties

A. Duty of Lawfulness

A regulator cannot exercise powers beyond its enabling legislation. Tariff determinations, licensing decisions and regulatory methodologies must remain within the authority granted by Parliament.

B. Duty of Public Participation

Because energy decisions can affect households, municipalities, businesses and vulnerable communities, regulators must create genuine opportunities for affected persons to participate. Participation must be meaningful rather than merely formal.

C. Duty of Transparency and Accountability

Regulators must explain the basis of important decisions and make relevant information reasonably accessible. Confidentiality cannot automatically be used to prevent meaningful scrutiny of regulatory decisions.

D. Duty to Act Without Undue Delay

Regulatory delay can have constitutional consequences where it interferes with municipal budgeting, electricity access or public participation. Section 237 reinforces the requirement that constitutional obligations be performed diligently and without delay.

E. Duty to Protect Constitutional Rights

Energy regulation must operate consistently with rights including human dignity, equality, property, environmental rights and socioeconomic interests. Regulatory choices must therefore consider their consequences for communities and essential public services.

4. Case Law

Case 1: Organisation Undoing Tax Abuse v NERSA 2016

Facts: OUTA challenged NERSA's regulatory process concerning Eskom's Regulatory Clearing Account application.

Legal Issue: Whether NERSA was required to conduct a proper participatory and reasoned regulatory process.

Judgment: The court emphasised that NERSA was required to act properly and provide an informed decision with adequate reasons.

Legal Principle: A specialist regulator remains subject to constitutional and administrative-law standards.

Significance: Regulatory expertise does not remove the duties of fairness, transparency and accountability.

Case 2: Earthlife Africa Johannesburg v Minister of Energy

Facts: The dispute concerned governmental decisions relating to a proposed nuclear-energy project.

Legal Issue: Whether environmental and constitutional considerations had been properly incorporated into energy decision-making.

Judgment: The litigation demonstrated that major energy decisions must comply with environmental and administrative-law requirements.

Legal Principle: Energy governance cannot be separated from constitutional environmental and participatory obligations.

Significance: Regulatory and executive energy decisions remain reviewable where constitutional and administrative requirements are disregarded.

Case 3: AfriForum NPC v NERSA [2025] ZAGPPHC 1305

Facts: NERSA's repeated delays and public-participation processes concerning municipal electricity tariffs were challenged.

Legal Issue: Whether persistent regulatory delay and inadequate participation violated constitutional and statutory duties.

Judgment: The High Court held that NERSA's chronic lateness impaired municipal budgeting and meaningful public participation and imposed procedural timelines.

Legal Principle: Judicial deference to a specialist regulator cannot protect systemic constitutional non-compliance.

Significance: The case strongly illustrates that regulatory expertise operates within, rather than above, constitutional accountability.

5. Conclusion

Constitutional duties transform energy regulators from purely technical institutions into accountable constitutional actors. NERSA and comparable regulators must combine technical expertise with legality, transparency, participation, reasoned decision-making, constitutional rights protection and timely performance. The central principle is that regulatory discretion is not unlimited discretion. Energy regulators possess specialised authority, but that authority must continuously operate within the Constitution, legislation and the rule of law.
