QUEUE MANAGEMENT FOR GRID CONNECTIONS

1. Introduction

Queue management for grid connections refers to the legal, regulatory, and administrative system used to determine the order in which electricity generation, storage, and other projects obtain access to limited transmission or distribution capacity. It has become particularly important as renewable-energy and private-generation projects compete for connection to networks that cannot immediately accommodate every applicant.

In South Africa, grid constraints have been especially significant in major renewable-energy regions. Eskom identified constrained transmission corridors in the Northern Cape, Eastern Cape, and Western Cape, creating a need for allocation mechanisms that prevent scarce capacity from being reserved indefinitely by projects that are not ready to proceed.

2. From “First Come, First Served” to Project Readiness

Traditional connection queues commonly followed a first come, first served principle. Under this model, an applicant obtaining an early position could effectively reserve scarce capacity even where its project remained commercially, environmentally, or technically immature.

Eskom responded by introducing Interim Grid Capacity Allocation Rules (IGCAR) in 2023 based upon a “first ready, first served” approach. The objective was to allocate scarce connection capacity to projects demonstrating genuine readiness rather than merely possessing an earlier application date.

Readiness considerations have included matters such as environmental approvals, water-use requirements where applicable, evidence relating to off-take arrangements, technical preparation, and other indicators demonstrating that a project can realistically proceed.

3. Current Queue Structure

South Africa's framework has continued to develop. Grid-capacity allocation rules published in December 2025 establish a three-stage queuing structure: project registration, capacity reservation, and capacity allocation. Queue positions are linked to defined milestones and verified evidence of project readiness.

Importantly, queue management is therefore not necessarily a static chronological waiting list. A project progressing efficiently through required milestones may move ahead of an earlier project that fails to progress. This approach reduces speculative applications and capacity hoarding while encouraging developers to obtain permits, financing, land rights, and technical approvals promptly.

4. Capacity Reservation and Milestones

Effective queue governance requires clearly defined milestones. Applicants may initially enter the connection process, but permanent reservation of scarce network capacity should depend upon demonstrated progress.

Eskom's current guidance states that its connection process continues to operate according to First Ready, First Served principles. Where projects fail to advance, capacity may return to the available pool and become accessible to subsequent projects.

This creates a form of “use it or lose it” discipline, helping ensure that transmission capacity supports projects capable of contributing electricity within realistic timeframes.

5. Administrative-Law Requirements

Grid queue decisions can have enormous financial consequences. Allocation, refusal, withdrawal, or reassignment of connection capacity must therefore operate within applicable statutory and administrative-law requirements.

Decision-makers should apply published criteria consistently, consider relevant information, avoid improper purposes, and provide procedures compatible with lawfulness, rationality, transparency, and procedural fairness. These safeguards become particularly important where a network operator controls infrastructure essential for market participation.

6. CASE LAW

G7 Renewable Energies (Pty) Ltd v Eskom – IGCA Litigation (2023)

Facts: G7 Renewable Energies sought an interdict preventing Eskom from implementing its Interim Grid Capacity Allocation Rules and sought continued application of the previous first-come, first-served approach.

Legal Issue: Whether implementation of the new grid-capacity allocation regime should be restrained pending further legal proceedings.

Judgment: In July 2023, the Johannesburg High Court dismissed the interim interdict application with costs, allowing implementation of the rules to continue.

Legal Principle/Ratio: The proceedings illustrate that allocation of scarce grid capacity may legitimately involve consideration of project readiness and broader system requirements, subject to administrative-law scrutiny.

Significance: The dispute directly demonstrates the legal tension between established queue positions and regulatory efforts to ensure efficient utilisation of scarce transmission capacity.

Sibanye Gold (Pty) Ltd v Eskom Holdings SOC Ltd [2026] ZAGPJHC 123

Facts: Sibanye sought a wayleave necessary for infrastructure associated with a 50 MW solar PV project. Eskom refused the application.

Legal Issue: Whether Eskom's refusal constituted lawful administrative decision-making.

Judgment: The High Court reviewed and set aside the refusal, finding improper considerations and errors affecting Eskom's decision, and substituted it with a decision granting the wayleave.

Legal Principle/Ratio: Network-related powers cannot be exercised for ulterior purposes or on irrational and legally erroneous grounds.

Significance: The case reinforces that grid-access administration, including decisions affecting connection progression, remains constrained by PAJA and the principle of legality.

7. Conclusion

Queue management is essential where grid capacity is scarce. A well-designed system combines project readiness, transparent milestones, non-discrimination, efficient capacity utilisation, and administrative fairness. South Africa's movement toward readiness-based allocation demonstrates how electricity law can prevent capacity hoarding while accelerating viable renewable and private-generation projects. At the same time, allocation decisions must remain rational, transparent, procedurally fair, and consistent with statutory authority.
