Competitive Delivery Models in Network Expansion

1. Introduction

Competitive delivery models in network expansion refer to methods of developing electricity transmission and distribution infrastructure through competitive procurement, private participation, concessions, independent power or network developers, and other market-based arrangements.

Electricity networks require large investments in transmission lines, substations, transformers, distribution systems and digital grid infrastructure. Because network infrastructure often has natural-monopoly characteristics, it may not be efficient for several companies to construct duplicate networks in the same area.

Therefore, competition can be introduced through the delivery process, even where the physical network itself remains regulated.

2. Meaning of Competitive Network Delivery

Traditional network expansion may involve a government-owned utility planning, financing, constructing and operating all infrastructure.

A competitive model can divide these functions among different participants.

For example, government or a regulator may invite companies to compete to:

design a transmission project;

construct a new transmission line;

finance network infrastructure;

operate a particular network facility;

provide distribution infrastructure;

install smart-grid equipment; or

maintain network assets.

The successful participant is selected according to transparent criteria such as cost, technical quality, reliability, construction time and long-term performance.

3. Why Competition Is Useful

A. Lower Infrastructure Costs

Competitive bidding can place pressure on companies to offer efficient construction and operating costs.

B. Faster Development

Private participation can provide additional financial and technical capacity for network expansion.

C. Innovation

Competition may encourage the use of smart-grid technology, advanced transformers, automated systems and digital monitoring.

D. Reduced Dependence on One Supplier

Competitive procurement can prevent excessive dependence on a single construction or equipment supplier.

E. Better Value for Money

Government or the network operator can compare different technical and financial proposals before selecting a project developer.

4. Main Delivery Models

4.1 Competitive Tendering

A public authority invites companies to bid for construction or maintenance of a network project.

4.2 Concession Model

A private company receives a defined right to develop or operate network infrastructure for a specified period.

4.3 Public-Private Partnership

The public sector and private investors share responsibilities for financing, construction and operation.

4.4 Independent Transmission or Network Developer

An independent entity may develop specific network assets subject to regulatory oversight.

4.5 Design-Build Procurement

A company competes to design and construct the infrastructure while ownership or long-term operation remains with the public network operator.

5. Competition Law Concerns

Competitive delivery must be carefully designed because infrastructure projects can involve large contracts.

Bid Rigging

Companies may agree in advance who will win a particular contract.

Market Sharing

Competitors may divide geographic areas or network projects among themselves.

Supplier Concentration

A small number of companies may control specialised equipment or construction services.

Preferential Treatment

A network operator could favour an affiliated company through confidential information, technical specifications or contract conditions.

Vertical Integration

If the same company controls network assets and also operates generation or electricity trading businesses, regulators should consider whether access to infrastructure could be used to disadvantage competitors.

6. South African Legal Framework

Section 217 of the South African Constitution requires public procurement to be fair, equitable, transparent, competitive and cost-effective.

The Competition Act 89 of 1998 also applies where procurement arrangements involve prohibited collusion, restrictive agreements, abuse of dominance or mergers.

Electricity-network expansion additionally operates within electricity-sector regulation, including licensing, grid-access requirements and technical standards.

7. Important Case Laws

AllPay Consolidated Investment Holdings v SASSA

In AllPay, the Constitutional Court emphasised the importance of compliance with procurement requirements and constitutional procurement principles.

Although it was not an electricity infrastructure case, the principle is directly relevant to competitive network delivery. A tender process must be structured and implemented according to lawful and transparent rules.

Competition Commission v Waco Africa

Waco Africa is particularly relevant by analogy to electricity infrastructure procurement because it concerned collusive tendering connected with Eskom procurement.

The case demonstrates that competitive procurement can fail if bidders coordinate their prices or otherwise manipulate the tender process.

Competition Commission v Senwes

In Senwes, the Constitutional Court examined market power and vertical relationships involving storage infrastructure.

Although the infrastructure was grain storage rather than electricity networks, the case provides a useful analogy for situations where control of important infrastructure can affect competition in related markets.

Competition Commission v Telkom

The Telkom case involved exclusionary conduct associated with telecommunications infrastructure.

Its broader importance for electricity is that control over essential network infrastructure can create competition concerns if access is restricted or competitors are disadvantaged.

8. Regulatory Safeguards

A successful competitive network-delivery model should provide:

transparent tender documents;

objective evaluation criteria;

equal access to information;

independent bid evaluation;

anti-collusion measures;

clear construction standards;

reasonable contract duration;

performance guarantees;

non-discriminatory network access; and

regulatory monitoring.

The regulator should also ensure that competition during construction does not disappear into a permanent private monopoly after the project is completed.

9. Conclusion

Competitive delivery models can help expand electricity networks while controlling costs and encouraging private investment and innovation. Because transmission and distribution networks have natural-monopoly characteristics, the objective is generally not to construct multiple competing networks. Instead, competition can occur in project selection, construction, financing, technology supply and service delivery.

The principles illustrated by AllPay, Waco Africa, Senwes and Telkom show the importance of transparent procurement, genuine competition and safeguards against infrastructure-related market power.

A balanced model should therefore combine competitive procurement with strong network regulation, fair access, technical standards and long-term accountability.
