Constitutional Sovereignty and Electricity Regulation

1. Introduction

Constitutional sovereignty means that the Constitution is the highest legal authority in the country. Government departments, regulators, public companies and municipalities must exercise their powers according to the Constitution. In South Africa, this principle is particularly important in electricity regulation because electricity involves public resources, economic development, essential services, environmental protection and large public expenditure.

Electricity regulation therefore cannot be based only on government policy or administrative decisions. It must comply with constitutional principles such as constitutional supremacy, legality, accountability, equality, administrative justice, cooperative government and protection of fundamental rights.

2. Constitutional Supremacy

Section 2 of the South African Constitution provides that the Constitution is the supreme law of the Republic. Any law or conduct inconsistent with it is invalid.

This means that electricity legislation and regulatory decisions must comply with constitutional requirements. The Electricity Regulation Act 4 of 2006 (ERA), the National Energy Regulator Act 7 of 2004, municipal electricity decisions and decisions of the National Energy Regulator of South Africa (NERSA) are all subject to constitutional review.

This creates a hierarchy:

Constitution → legislation → regulations and policies → individual regulatory decisions.

No electricity regulator can exercise powers outside this legal framework.

3. Constitutional Sovereignty and the Principle of Legality

Constitutional sovereignty is closely connected with the rule of law. Public officials cannot exercise power simply because they believe that doing so would improve the electricity system.

In Pharmaceutical Manufacturers Association of SA: In re Ex Parte President of the Republic of South Africa 2000 (2) SA 674 (CC), the Constitutional Court established that the exercise of public power must comply with constitutional principles, including legality and rationality.

For electricity regulation, this means that decisions relating to licensing, tariffs, procurement, grid access, electricity supply and market regulation must have a lawful basis.

4. Constitutional Distribution of Electricity Powers

Electricity governance in South Africa involves different spheres of government.

The Constitution gives national government important responsibilities concerning energy policy and electricity generation and transmission, while electricity reticulation is listed under Schedule 4B as a municipal function.

This division can create disputes between Eskom, municipalities and national government.

In Eskom Holdings SOC Ltd v Vaal River Development Association (Pty) Ltd 2023 (4) SA 325 (CC), the Constitutional Court considered the constitutional and statutory division of responsibilities concerning electricity supply. The Court emphasised that electricity governance must be understood within the constitutional structure of government.

Similarly, Eskom Holdings SOC Ltd v Lekwa Local Municipality and Others [2022] ZASCA 26 concerned the relationship between Eskom and municipal electricity responsibilities.

These cases demonstrate that constitutional sovereignty requires electricity institutions to remain within their legally assigned powers.

5. Cooperative Government

Sections 40 and 41 of the Constitution establish a system of cooperative government. National, provincial and local governments must cooperate and avoid unnecessary conflict.

This is especially important in electricity regulation because electricity projects frequently involve:

national government;

municipalities;

Eskom;

NERSA;

private electricity producers;

communities; and

environmental authorities.

Electricity regulation cannot function effectively if these institutions exercise overlapping powers without coordination.

6. Constitutional Rights and Electricity Regulation

Constitutional sovereignty also requires electricity regulation to respect fundamental rights.

Relevant rights include:

Section 9: equality;

Section 10: dignity;

Section 24: environmental protection;

Section 25: property;

Section 33: just administrative action.

In Joseph and Others v City of Johannesburg and Others 2010 (4) SA 55 (CC), the Constitutional Court considered the termination of electricity supply to residents. The Court recognised the importance of electricity services and held that procedural fairness was required before termination.

The case demonstrates that electricity regulation and service delivery must operate consistently with constitutional rights.

7. Regulatory Discretion and Constitutional Review

NERSA has specialised technical responsibilities. However, regulatory expertise does not place it outside constitutional review.

In Bato Star Fishing (Pty) Ltd v Minister of Environmental Affairs and Tourism 2004 (4) SA 490 (CC), the Constitutional Court explained that courts should recognise the expertise of specialised administrative bodies while still ensuring that administrative decisions comply with law and constitutional standards.

Therefore, NERSA may make technically complex electricity decisions, but its decisions must remain lawful, reasonable and procedurally fair.

8. Environmental Constitutional Sovereignty

Section 24 of the Constitution requires the state to protect the environment for present and future generations. Electricity regulation must therefore consider environmental and climate-related consequences.

In Earthlife Africa Johannesburg v Minister of Environmental Affairs 2017 (2) SA 519 (SCA), the court recognised that climate-change impacts were relevant when considering environmental authorisation for a proposed coal-fired power station.

This demonstrates that constitutional sovereignty includes environmental responsibilities and cannot be reduced to electricity production alone.

9. Conclusion

Constitutional sovereignty places the Constitution at the centre of electricity governance. Electricity regulators, Eskom, municipalities and government departments must exercise their powers within constitutional and statutory boundaries.

The most important safeguards are constitutional supremacy, legality, rationality, administrative justice, cooperative government, protection of rights and environmental responsibility.

Thus, constitutional sovereignty does not prevent the state from regulating electricity markets. Instead, it ensures that electricity regulation is conducted according to law, within institutional powers, transparently and consistently with constitutional values.
