Connection Agreement Disputes

1. Introduction

A connection agreement is an agreement between a generator, electricity consumer or other network user and a transmission or distribution licensee for connecting an electricity facility to the electricity network.

The agreement normally deals with the point of connection, technical standards, construction responsibilities, connection costs, metering, capacity, maintenance, safety, tariffs, liability and dispute resolution.

Connection agreement disputes arise when the parties disagree about the terms or implementation of the connection. These disputes are becoming increasingly important because South Africa is connecting more renewable-energy projects, embedded generation, battery storage facilities and private electricity users to the grid.

2. Common Types of Disputes

Several types of disputes may arise.

A. Connection Costs

A generator may disagree with the amount charged for network reinforcement, equipment, substations or connection infrastructure.

B. Delays in Connection

A project developer may argue that the network operator has delayed connection without adequate justification. This can cause significant financial losses where a generation project cannot begin commercial operation.

C. Technical Requirements

The network operator may require particular protection systems, transformers, metering equipment or grid-code compliance. A developer may challenge whether those requirements are technically or contractually justified.

D. Available Network Capacity

A dispute may arise when the network operator says that there is insufficient capacity to connect a proposed project.

E. Curtailment and Operating Restrictions

After connection, disagreements can arise concerning restrictions on generation, power export, wheeling or curtailment.

F. Contractual and Regulatory Conflicts

A connection agreement may contain contractual rights, while the Electricity Regulation Act and Grid Code impose regulatory obligations. The parties may therefore disagree about whether a matter should be resolved through the contract, NERSA or judicial review.

3. South African Legal Framework

Connection agreements operate within the Electricity Regulation Act 4 of 2006 (ERA), electricity licences, the relevant Grid Code and NERSA's regulatory framework.

The Grid Code establishes technical requirements for connecting and operating generation and network facilities. The ERA also provides an important dispute-resolution mechanism. Section 30 gives NERSA power to settle disputes between an end-user and a licensee.

The Constitutional Court in Eskom Holdings SOC Ltd v Vaal River Development Association (2022) emphasised that section 30 provides a statutory mechanism for electricity disputes and that parties may need to use this mechanism before seeking judicial review.

4. Important Case Laws

Sibanye Gold v Eskom (2026)

Sibanye Gold (Pty) Ltd v Eskom Holdings SOC Ltd and Others is particularly relevant to modern connection disputes.

The case involved a proposed solar PV facility and infrastructure associated with connecting the project to Eskom's network. Eskom refused a wayleave relating to infrastructure crossing its transmission lines. The High Court reviewed the decision and declared it unlawful and constitutionally invalid, setting it aside.

The case did not decide a conventional contractual connection-agreement dispute. However, it is highly relevant by analogy because it demonstrates that decisions affecting access to electricity infrastructure must have a lawful and properly supported basis.

The court later refused Eskom leave to appeal.

Du Plooy v Van Zyl (2022)

This case demonstrates the importance of the dispute-resolution clause contained in an electricity agreement.

The agreement required the parties first to attempt informal negotiation and then, if necessary, to use arbitration through the Arbitration Foundation of Southern Africa. The applicants instead pursued a NERSA complaint. The court held that the contractual dispute-resolution mechanism was important because the parties had agreed to arbitration.

The lesson is that a connection agreement should clearly identify whether disputes go to negotiation, NERSA, arbitration or court proceedings.

Eskom v Letsemeng Local Municipality (2022)

The dispute concerned non-payment under an electricity-supply relationship and Eskom's proposed interruption of supply. The SCA recognised the relevance of the ERA's statutory dispute-resolution mechanism.

Although the case concerned supply rather than a physical grid connection, it demonstrates how contractual electricity disputes interact with statutory regulatory remedies.

Cape Gate v Eskom (2018)

In Cape Gate (Pty) Ltd v Eskom Holdings SOC Ltd, industrial electricity consumers challenged Eskom's proposed interruption of electricity supply. The litigation involved contractual, administrative and regulatory considerations.

The case illustrates the importance of considering both contractual rights and public-law obligations when an electricity network decision affects users.

Eskom v City of Johannesburg (2024)

The High Court examined electricity supply agreements between Eskom and the City of Johannesburg and considered the contractual terms governing electricity supply and tariffs.

This reinforces the importance of carefully drafted electricity agreements and the relationship between contractual terms and regulated electricity tariffs.

5. Role of NERSA

NERSA can become important where a dispute falls within its statutory jurisdiction. However, parties must distinguish between:

a purely contractual dispute;

a regulatory dispute;

a technical Grid Code dispute; and

an administrative decision that may be reviewed under PAJA.

The correct forum depends on the nature of the dispute and the terms of the agreement.

6. Legal Principles for Connection Agreements

A sound connection agreement should provide:

Clear technical standards: The parties should know exactly what equipment and grid requirements apply.

Defined costs: Connection and network-reinforcement costs should be clearly allocated.

Timelines: The agreement should establish realistic connection milestones.

Capacity rules: Available and reserved capacity should be clearly identified.

Dispute resolution: Negotiation, NERSA processes, arbitration and court remedies should be clearly distinguished.

Transparency: Reasons for refusing or delaying connection should be properly recorded.

Conclusion

Connection agreement disputes arise where disagreements develop over network access, technical requirements, connection costs, capacity, delays, tariffs, curtailment or contractual obligations.

South African law requires these disputes to be considered within both the contractual framework and the statutory electricity-regulation framework. Sibanye Gold v Eskom, Du Plooy v Van Zyl, Eskom v Letsemeng, Cape Gate v Eskom, and Eskom v City of Johannesburg demonstrate important principles concerning infrastructure access, contractual dispute resolution, regulatory remedies and electricity-supply agreements.

As renewable generation and private electricity projects expand, clear connection agreements and transparent dispute-resolution procedures will become increasingly important for fair and reliable grid development.
