Competition Remedies in Retail Electricity Markets

1. Introduction

Retail electricity markets are the part of the electricity sector where electricity is supplied to final consumers, including households, businesses, industries and public institutions. Competition in retail markets can give consumers greater choice, better services and potentially more efficient prices.

However, retail electricity markets may face competition problems because of dominant suppliers, municipal monopolies, long-term contracts, high switching costs, limited network access and unequal access to customer information.

Competition remedies are legal measures used to correct these problems and restore effective competition. In South Africa, the Competition Act 89 of 1998 works alongside electricity-sector regulation.

2. Meaning of Competition Remedies

A competition remedy is a legal measure designed to stop anti-competitive conduct or prevent its continuation.

In retail electricity markets, remedies may include:

prohibiting anti-competitive agreements;

changing restrictive contracts;

requiring non-discriminatory network access;

preventing discriminatory treatment;

imposing financial penalties;

requiring information disclosure;

imposing merger conditions; and

structural separation in serious cases.

The appropriate remedy depends on the specific competition problem.

3. Abuse of Dominance

A dominant electricity supplier may have substantial control over a particular retail market, especially where consumers have few alternative suppliers.

Potentially problematic conduct may include:

excessive pricing;

refusal to supply;

discriminatory pricing;

loyalty-inducing arrangements;

exclusive contracts;

tying and bundling; and

exclusion of competing retailers.

Under section 8 of the South African Competition Act, specified forms of conduct by dominant firms are prohibited.

Importantly, dominance itself is not unlawful. The authority must establish the prohibited conduct and the applicable legal requirements.

4. Excessive Pricing Remedies

Retail electricity prices can raise competition concerns where consumers have no realistic alternatives.

In Sasol Chemical Industries Ltd v Competition Commission, the Competition Appeal Court considered excessive pricing under section 8(a) of the Competition Act.

The case demonstrates that excessive-pricing analysis requires economic evidence. A high price alone does not automatically establish an infringement.

In electricity retail markets, authorities may consider:

costs;

investment requirements;

comparable prices;

profitability;

market conditions; and

availability of alternatives.

Any price-related remedy should also preserve incentives for investment and reliable electricity supply.

5. Discriminatory Treatment

A dominant electricity retailer could potentially disadvantage some customers or competing businesses through discriminatory terms.

For example, a retailer might offer favourable conditions to an affiliated company while imposing less favourable conditions on independent businesses.

A remedy could require:

objective pricing criteria;

equal treatment;

transparent contracts; and

non-discriminatory access.

These measures are particularly important where one company controls both electricity supply and essential network infrastructure.

6. Long-Term and Exclusive Contracts

Long-term electricity contracts can provide investment certainty. However, very restrictive contracts may make it difficult for competing retailers to enter the market.

Competition authorities may examine:

contract duration;

exclusivity;

termination provisions;

customer switching costs; and

the supplier's market position.

Where an agreement substantially restricts competition, a possible remedy may involve modifying the restrictive clause or preventing future use of similar arrangements.

The principles from Competition Commission of South Africa v Senwes Ltd are useful by analogy. The case concerned exclusionary conduct and contractual arrangements involving a dominant firm and important storage infrastructure.

7. Network Access Remedies

Retail competition depends on access to electricity networks.

A new retailer may be unable to compete if it cannot obtain fair access to distribution infrastructure.

Therefore, remedies may require:

transparent connection procedures;

non-discriminatory network access;

transparent charges;

objective technical requirements; and

effective dispute-resolution procedures.

Competition through the network is particularly important because it may be economically inefficient to construct duplicate distribution networks.

8. Telkom Case and Infrastructure Access

Competition Commission v Telkom SA Ltd provides an important comparative South African precedent concerning competition and essential network infrastructure.

Although it concerned telecommunications rather than electricity, the case demonstrates how control over an important network can potentially be used to restrict competition in related markets.

Its principles are therefore relevant by analogy to electricity distribution networks where network control affects the ability of independent retailers to reach customers.

9. Merger Remedies

Retail electricity markets may become concentrated through mergers between:

electricity retailers;

generation and retail businesses;

energy-service companies;

electricity traders; or

vertically integrated energy groups.

Competition authorities may impose merger conditions where necessary.

Possible conditions include:

divestiture of assets;

restrictions on exclusive contracts;

access commitments;

non-discrimination requirements; and

information-separation measures.

The purpose is to preserve competitive alternatives while allowing legitimate efficiencies.

10. Customer Switching

Effective competition requires consumers to be able to change suppliers where retail choice exists.

Competition remedies may therefore address:

excessive switching fees;

complicated switching procedures;

misleading information;

automatic renewal clauses; and

unreasonable termination requirements.

Lower switching barriers can make retailers compete more actively for customers.

However, consumer-protection rules and competition remedies should be coordinated so that consumers receive clear and accurate information.

11. Information and Data

Modern electricity retailers collect large amounts of information concerning:

electricity consumption;

customer preferences;

payment behaviour;

demand patterns; and

distributed-energy resources.

A vertically integrated electricity company could potentially use commercially sensitive information to disadvantage independent competitors.

Appropriate remedies may include:

information firewalls;

equal access to necessary market information;

restrictions on discriminatory data use; and

transparent data-sharing rules.

12. Municipal Electricity Markets

South African municipalities play an important role in electricity distribution and retail supply.

Competition issues may arise where municipal arrangements interact with:

private electricity suppliers;

embedded generation;

rooftop solar;

independent power producers; and

electricity traders.

In Cape Gate (Pty) Ltd v Emfuleni Local Municipality, the Competition Tribunal considered an excessive-pricing complaint concerning electricity supplied by a municipality.

The case illustrates how competition law can interact with electricity pricing and public-sector electricity supply.

13. Renewable Energy and Retail Competition

Distributed solar generation, battery storage and embedded generation are changing retail electricity markets.

Consumers may increasingly obtain electricity through:

rooftop solar;

private generators;

battery systems;

wheeling arrangements; and

independent electricity suppliers.

Competition remedies should therefore prevent incumbent suppliers from unnecessarily blocking legitimate alternatives.

At the same time, technical grid requirements and reliability standards remain legitimate regulatory concerns.

14. Conclusion

Competition remedies in retail electricity markets are designed to protect and restore effective competition while maintaining reliable electricity supply.

Important remedies include price-related remedies, non-discrimination obligations, network-access requirements, modification of restrictive contracts, merger conditions, switching protections and financial penalties.

The Sasol Chemical Industries, Senwes, Telkom, and Cape Gate cases provide useful principles concerning excessive pricing, exclusionary conduct, network infrastructure and municipal electricity pricing.

The central objective is to ensure that electricity retailers compete fairly, consumers have meaningful choices where retail competition is available, and dominant suppliers cannot unlawfully use their market position to exclude competitors.
