Competition Law and Infrastructure Convergence and Market Power

1. Introduction

Infrastructure convergence refers to the increasing integration, sharing, interconnection, and functional overlap of infrastructure that was traditionally operated through separate networks or sectors.

Examples include:

telecommunications infrastructure used for cloud and digital services;

electricity grids supporting data centres and digital infrastructure;

railway infrastructure carrying fibre-optic networks;

roads and transport infrastructure supporting digital logistics;

telecom towers shared by multiple operators;

energy infrastructure supporting hydrogen, electric-vehicle and data-centre ecosystems;

ports integrating logistics, communications and digital platforms;

satellite, telecom and cloud infrastructure;

smart-city infrastructure combining telecommunications, energy, transport and data systems.

This convergence can produce significant efficiencies. A single physical or digital infrastructure may support several markets simultaneously. At the same time, it can create new forms of market power, because control over one infrastructure layer can provide leverage over several downstream markets.

The competition-law question is therefore:

When does infrastructure integration create legitimate efficiencies, and when does control over converged infrastructure become a mechanism for foreclosure, exclusion or extension of market power?

Modern EU competition policy expressly recognises that infrastructure sharing can reduce deployment costs and improve connectivity, while also warning that sharing arrangements can reduce infrastructure competition and thereby affect wholesale and retail competition. (Eur-Lex)

2. Meaning of Infrastructure Convergence

Traditional infrastructure markets were often vertically separated.

For example:

Electricity generation → transmission → distribution

Railway tracks → train operators → passengers

Telecom towers → mobile networks → communications services

Ports → shipping companies → logistics services

Infrastructure convergence changes this structure.

A single infrastructure may increasingly perform several functions:

Physical infrastructure → communications infrastructure → data infrastructure → platform infrastructure → commercial ecosystem

For example, a telecom tower can support:

mobile communications;

IoT;

smart-city sensors;

edge computing;

emergency communications;

autonomous vehicles; and

industrial connectivity.

The owner of that infrastructure may therefore possess competitive significance in several interconnected markets.

3. Infrastructure Convergence and Market Power

Market power can arise at different levels.

Level 1 — Physical infrastructure

Examples:

fibre networks;

railway tracks;

electricity transmission;

ports;

pipelines;

towers;

ducts;

airports.

Level 2 — Network infrastructure

Examples:

telecommunications networks;

electricity grids;

transport networks;

payment networks.

Level 3 — Digital infrastructure

Examples:

cloud infrastructure;

data centres;

APIs;

identity infrastructure;

operating systems;

digital platforms.

Level 4 — Information infrastructure

Examples:

databases;

traffic information;

energy data;

customer data;

industrial data.

Level 5 — Platform infrastructure

Examples:

marketplaces;

app stores;

cloud marketplaces;

logistics platforms;

digital advertising infrastructure.

The higher the number of markets dependent upon the same infrastructure, the greater the possibility that infrastructure control can generate cross-market leverage.

4. Why Infrastructure Convergence Can Increase Market Power

A. Economies of scale

Infrastructure often involves substantial fixed costs.

Once infrastructure is constructed, the marginal cost of serving another user may be relatively low.

This can create:

high entry costs;

economies of scale;

natural-monopoly characteristics; and

substantial advantages for incumbents.

B. Network effects

Infrastructure becomes more valuable as more users connect to it.

For example:

More telecom users → greater network value → more applications → more users.

The same principle can operate in:

payments;

cloud computing;

transport platforms;

logistics;

IoT;

energy management.

5. Scope Economies

Convergence can produce economies of scope.

A company that already possesses:

fibre;

towers;

data centres;

electricity infrastructure;

customer information;

may be able to use the same infrastructure for several products.

This can lower costs.

But it can also create an advantage that competitors cannot replicate because they must construct separate infrastructure for each service.

6. Vertical Integration

Infrastructure convergence often encourages vertical integration.

For example:

Infrastructure owner
↓
Wholesale access provider
↓
Platform
↓
Retail service

Vertical integration is not inherently anticompetitive.

The problem arises where the vertically integrated infrastructure owner can:

discriminate against competitors;

increase access prices;

degrade quality;

delay access;

restrict interoperability;

bundle infrastructure with downstream services;

impose exclusivity;

refuse access; or

use sensitive information obtained from infrastructure users.

7. Horizontal Infrastructure Sharing

Two competitors may share infrastructure.

Examples include:

telecom tower sharing;

fibre sharing;

railway facilities;

energy networks;

data centres;

spectrum;

charging infrastructure.

Infrastructure sharing can be pro-competitive because it may:

reduce duplication;

lower capital expenditure;

accelerate deployment;

improve coverage;

reduce environmental costs;

permit entry by smaller firms.

But it can also reduce the incentives of the parties to compete through independent infrastructure investment.

The European Commission has specifically recognised that infrastructure-sharing arrangements may reduce infrastructure competition and consequently affect wholesale and retail competition. (Eur-Lex)

8. Network-Sharing Agreements and Competition

A network-sharing agreement may affect several competitive parameters:

price;

quality;

capacity;

geographic coverage;

technology;

investment;

innovation;

rollout speed.

Therefore, competition analysis should not focus exclusively on price.

A sharing arrangement that results in:

fewer independent networks → less independent investment → reduced technological competition

may have long-term competitive consequences.

At the same time, passive sharing may create substantial efficiencies without eliminating meaningful competition.

Consequently, infrastructure-sharing agreements generally require case-by-case analysis rather than an automatic finding of illegality. (Eur-Lex)

9. Access to Converged Infrastructure

One of the most important questions is:

Who gets access to the infrastructure?

A dominant infrastructure owner might provide access to:

some competitors but not others;

its own subsidiary on better terms;

selected customers;

affiliated platforms;

preferred downstream businesses.

Competition authorities may investigate:

Price discrimination

Different access prices for similarly situated competitors.

Quality discrimination

Providing slower or inferior access to rivals.

Technical discrimination

Providing better APIs, interfaces or interoperability to affiliated businesses.

Delayed access

Creating delays that disadvantage competitors.

Capacity discrimination

Allocating scarce capacity preferentially.

10. Essential Facilities Doctrine

The essential facilities doctrine is highly relevant to infrastructure convergence.

The basic question is whether a dominant undertaking controls infrastructure that competitors genuinely cannot reasonably duplicate or substitute.

The doctrine is associated with cases such as:

United States v Terminal Railroad Association;

MCI Communications Corp. v AT&T;

Oscar Bronner v Mediaprint;

Magill;

IMS Health;

Microsoft.

However, courts have generally imposed demanding conditions before requiring compulsory access.

A facility being:

expensive,

convenient,

or

commercially advantageous

does not necessarily make it legally essential.

11. Case Law 1 — United States v Terminal Railroad Association, 224 U.S. 383 (1912)

Facts

A group of railroad companies controlled essential terminal facilities in St. Louis.

Competitors seeking to operate railway services faced substantial barriers because access to the terminal infrastructure was controlled by the existing participants.

Principle

The U.S. Supreme Court found the arrangement problematic because control over the terminal infrastructure could prevent competitors from effectively competing in the relevant railway market.

Importance

This is one of the foundational infrastructure-access cases.

It demonstrates that:

control over a bottleneck infrastructure facility can translate into control over downstream competition.

Relevance to infrastructure convergence

Modern equivalents could include:

a dominant fibre network;

a critical electricity connection;

a port facility;

a railway terminal;

a digital infrastructure gateway.

12. Case Law 2 — Otter Tail Power Co. v United States, 410 U.S. 366 (1973)

Facts

Otter Tail operated an integrated electric power system and supplied electricity in several communities.

Municipalities sought to establish their own electricity distribution systems and required access to transmission facilities.

Otter Tail resisted providing transmission access in circumstances relevant to the litigation.

Principle

The Supreme Court treated control over transmission facilities as significant to competition in downstream electricity distribution.

Relevance

The case demonstrates the relationship between:

upstream infrastructure control → downstream market access.

This principle becomes especially important under infrastructure convergence because a single network may simultaneously support several competitive markets.

13. Case Law 3 — MCI Communications Corp. v AT&T, 708 F.2d 1081 (7th Cir. 1983)

Facts

MCI sought interconnection with AT&T's telecommunications network.

AT&T controlled significant telecommunications infrastructure.

Principle

The Seventh Circuit developed a well-known framework for analysing refusal to provide access to an essential facility.

The analysis considered matters including:

control of the facility by a monopolist;

inability of competitors reasonably to duplicate it;

denial of access; and

feasibility of providing access.

Relevance

This case is particularly important for converged infrastructure because interconnection is frequently the mechanism through which one network connects to another.

Modern applications may involve:

telecommunications;

cloud infrastructure;

payment networks;

energy systems;

transport networks;

digital identity systems.

14. Case Law 4 — Oscar Bronner GmbH & Co. KG v Mediaprint, C-7/97

Facts

Bronner operated a newspaper and sought access to Mediaprint's newspaper-delivery system.

Mediaprint had a substantial delivery network.

Principle

The Court of Justice imposed stringent requirements before a refusal to provide access could constitute abuse of dominance.

The infrastructure generally had to be indispensable and the refusal had to threaten the elimination of effective competition, among other requirements.

Relevance

The case remains important because infrastructure convergence creates frequent demands for access.

The existence of:

a cheaper,

more efficient,

or

more convenient

infrastructure does not automatically make that infrastructure an essential facility.

15. Case Law 5 — Microsoft Corp. v Commission, T-201/04

Facts

Microsoft possessed substantial power in PC operating systems.

The European Commission found problems concerning Microsoft's refusal to provide interoperability information necessary for competitors in the work-group server market.

Principle

The case demonstrated that technological information and interoperability can become competitively indispensable under particular circumstances.

Relevance

Infrastructure convergence increasingly involves software-defined infrastructure.

Physical infrastructure is increasingly controlled through:

APIs;

protocols;

operating systems;

cloud interfaces;

data formats;

software management layers.

Thus:

control of information infrastructure can produce effects similar to control of physical infrastructure.

16. Case Law 6 — Slovak Telekom v European Commission, C-165/19 P

Facts

Slovak Telekom was the incumbent telecommunications operator and was subject to regulatory obligations relating to local-loop access.

The dispute concerned conditions imposed on competitors seeking access and allegations of exclusionary conduct.

Principle

The Court examined the relationship between regulated access obligations, dominance and abusive access conditions.

The case is particularly important because the legal analysis distinguishes between an outright refusal to supply and conduct involving conditions imposed on access. (Eur-Lex)

Relevance

This is directly applicable to converged infrastructure because modern disputes often involve:

"I will provide access, but only on these conditions."

The conditions themselves may therefore become the competition-law issue.

17. Case Law 7 — CK Telecoms UK Investments Ltd v European Commission, T-399/16

Facts

The case concerned the proposed acquisition of Telefónica Europe by Hutchison 3G UK in the UK mobile telecommunications sector.

The Commission examined:

market concentration;

close competitors;

network-sharing arrangements;

wholesale access;

retail competition;

infrastructure investment.

Principle

The case illustrates the importance of assessing not merely market shares but also:

competitive constraints;

network-sharing arrangements;

infrastructure investment;

wholesale relationships; and

non-coordinated effects.

The General Court's judgment specifically addressed the relationship between the transaction and network-sharing arrangements and the potential impact on mobile-network infrastructure development. (Eur-Lex)

Relevance

It is a particularly useful precedent for understanding how concentrated infrastructure markets can affect both retail competition and infrastructure investment.

18. Case Law 8 — Iliad Italia v Commission, T-692/20

Facts

The case concerned a transaction involving the grouping of passive mobile infrastructure into a joint venture.

Access to the resulting infrastructure was an important element of the commitments examined by the Commission.

Principle

The case illustrates the competition-law importance of:

passive infrastructure;

joint infrastructure ownership;

access commitments;

potential discrimination;

implementation of merger remedies.

The General Court considered whether the Commission had adequately assessed the commitments concerning access to the infrastructure and safeguards against discriminatory site selection. (Eur-Lex)

Relevance

This case is especially important for infrastructure convergence because it demonstrates how competition authorities can allow infrastructure consolidation while using access remedies to preserve downstream competition.

19. Infrastructure Convergence and Self-Preferencing

A converged infrastructure operator may also compete against firms that depend upon its infrastructure.

For example:

Fibre network owner
+
cloud platform
+
content service

The infrastructure owner could potentially provide better:

bandwidth;

latency;

access;

data;

technical support;

interoperability

to its own downstream service.

This creates a classic vertical foreclosure problem.

20. Infrastructure Convergence and Bundling

A dominant infrastructure provider may bundle several services.

For example:

telecom access + cloud storage + cybersecurity + data analytics.

A customer may technically have the ability to purchase the components separately, but contractual or technical bundling can make independent providers less competitive.

Competition authorities may examine:

tying;

bundling;

loyalty discounts;

conditional rebates;

exclusivity;

minimum-purchase obligations.

21. Cross-Market Leveraging

One of the most important risks of convergence is leveraging.

Suppose Firm A controls:

electricity infrastructure.

It subsequently enters:

electric-vehicle charging.

Then:

charging infrastructure → EV services → mobility platform.

If Firm A uses control over the electricity infrastructure to disadvantage rival charging operators, its infrastructure dominance may potentially be extended into a neighbouring market.

The same pattern can occur with:

telecom → cloud;

rail → logistics;

port → shipping services;

energy → hydrogen;

cloud → AI;

data centres → digital platforms.

22. Infrastructure Data as a Competitive Asset

Converged infrastructure generates enormous amounts of data.

Examples include:

traffic data;

energy-consumption data;

network-performance data;

customer demand;

location information;

capacity data;

logistics information;

machine-generated industrial data.

An infrastructure owner may therefore acquire informational advantages over competitors.

Potential concerns include:

discriminatory data access;

withholding commercially important data;

preferential access for affiliates;

combining datasets across markets;

using competitor-generated information to compete against those competitors.

23. Infrastructure Convergence and Information Asymmetry

Suppose several businesses depend upon an infrastructure operator.

The infrastructure operator may know:

how much capacity each competitor uses;

where competitors are expanding;

what their customers demand;

their peak usage;

their operational weaknesses;

their investment plans.

This information can become competitively sensitive.

Competition law may therefore need to consider not merely physical access, but also:

informational access and informational neutrality.

24. Infrastructure Sharing and Cartel Risk

Infrastructure sharing between competitors creates another important concern.

The parties may legitimately need to exchange information necessary to operate shared infrastructure.

But excessive information exchange could facilitate coordination.

For example, competitors sharing telecommunications infrastructure might unnecessarily exchange:

future pricing plans;

customer strategies;

rollout plans;

investment decisions;

commercially sensitive capacity information.

The European Commission has expressly noted that information exchange between parties to infrastructure-sharing arrangements can create competition concerns where it goes beyond what is strictly necessary for the arrangement. (Eur-Lex)

Therefore:

Infrastructure sharing should not become a mechanism for commercial coordination.

25. Infrastructure Convergence and Merger Control

Merger control becomes particularly important when two firms control complementary infrastructure.

Consider:

Merger A

Telecom network + cloud infrastructure

Merger B

Port + logistics platform

Merger C

Electricity grid + EV charging network

Merger D

Rail infrastructure + freight platform

Merger E

Data centre + AI platform

The merged firm may acquire the ability to:

foreclose rivals;

bundle services;

discriminate in access;

raise rivals' costs;

control complementary infrastructure;

obtain large datasets.

Thus traditional market-share analysis may be insufficient.

26. Vertical Foreclosure

Vertical foreclosure can take two major forms.

Input foreclosure

The infrastructure owner prevents downstream competitors from obtaining competitive access.

Example:

Fibre infrastructure → denies or worsens access to competing internet providers.

Customer foreclosure

A downstream platform controlled by the infrastructure owner absorbs demand and prevents rival infrastructure suppliers from obtaining sufficient customers.

Both can reduce effective competition.

27. Infrastructure Convergence and Natural Monopoly

Some infrastructure markets exhibit natural-monopoly characteristics because duplication is economically inefficient.

Examples may include:

electricity transmission;

water networks;

railway tracks;

certain pipelines;

local telecom ducts.

Competition law cannot necessarily create multiple parallel infrastructures.

Instead, competition may be introduced at the service level.

This produces the model:

Monopoly infrastructure + competitive downstream services

The success of this model depends heavily upon:

fair access;

reasonable pricing;

non-discrimination;

interoperability;

transparency;

capacity allocation.

28. Access Pricing

Access pricing becomes crucial where infrastructure cannot easily be duplicated.

An infrastructure operator could potentially charge:

excessive prices;

discriminatory prices;

margin-squeeze prices;

loyalty-conditioned prices;

different prices to affiliated and unaffiliated firms.

Competition authorities may therefore examine whether wholesale prices prevent an equally efficient downstream competitor from competing effectively.

The Slovak Telekom litigation is particularly relevant to access conditions and margin-squeeze analysis in telecommunications. (Eur-Lex)

29. India: Competition Act, 2002

Infrastructure convergence can be analysed under several provisions of Indian competition law.

Section 3 — Anti-competitive agreements

Relevant where infrastructure competitors enter into arrangements involving:

infrastructure sharing;

market allocation;

coordinated capacity;

information exchange;

exclusionary agreements.

Section 4 — Abuse of dominant position

Potentially relevant conduct includes:

denial of market access;

discriminatory access;

unfair conditions;

unfair pricing;

leveraging;

tying;

limiting technical or market development.

Sections 5 and 6 — Combinations

These provisions become relevant when infrastructure convergence results from:

mergers;

acquisitions;

joint ventures;

consolidation of infrastructure assets.

The CCI can therefore examine whether consolidation eliminates important competitive constraints.

30. Infrastructure Convergence and Sector Regulation

Competition law frequently overlaps with sector-specific regulation.

Relevant regulators may include authorities responsible for:

telecommunications;

electricity;

railways;

airports;

ports;

petroleum and natural gas;

digital infrastructure.

This creates a dual-regulation problem.

A sector regulator may impose:

access obligations.

Competition law may separately ask:

whether the access conditions constitute abuse of dominance.

The two systems can therefore complement each other.

31. Ex Ante and Ex Post Regulation

Ex ante regulation

Rules are established before harmful conduct occurs.

Examples:

mandatory infrastructure sharing;

interoperability requirements;

access obligations;

non-discrimination rules.

Ex post competition enforcement

Authorities intervene after conduct occurs.

Examples:

refusal to supply;

discriminatory access;

tying;

excessive pricing;

foreclosure;

anti-competitive agreements.

Converged infrastructure markets may require a combination of both approaches.

32. Efficiency Justifications

Infrastructure convergence can produce significant legitimate efficiencies.

Cost reduction

Shared infrastructure reduces duplication.

Faster deployment

Firms can use existing infrastructure rather than construct parallel networks.

Greater coverage

Infrastructure sharing can extend services to areas where independent deployment would not be economical.

Innovation

Interoperability can encourage new services.

Environmental benefits

Infrastructure sharing can reduce:

construction;

energy consumption;

land use;

duplicated physical networks.

EU telecommunications policy expressly recognises that infrastructure sharing can facilitate high-capacity network deployment, particularly where replication is economically or physically difficult. (Eur-Lex)

33. But Efficiencies Must Be Distinguished from Foreclosure

A sharing arrangement may simultaneously create:

efficiency effects + exclusionary effects.

For example:

Positive:

Shared fibre → lower costs.

Potential negative:

Shared fibre → competitors become dependent on the same infrastructure → independent investment declines → infrastructure competition weakens.

Therefore, the correct competition-law analysis should examine the overall competitive structure, not simply whether infrastructure sharing produces cost savings.

34. Important Competition-Law Tests

When analysing infrastructure convergence, authorities should consider:

1. Relevant market

What infrastructure and services compete?

2. Market power

Does the undertaking possess substantial market power?

3. Replicability

Can competitors economically reproduce the infrastructure?

4. Substitutability

Are alternative infrastructures available?

5. Access

Do competitors depend upon the infrastructure?

6. Indispensability

Is access genuinely necessary?

7. Foreclosure

Does the conduct exclude competitors?

8. Efficiencies

Does convergence create measurable efficiencies?

9. Consumer effects

What happens to:

price;

quality;

choice;

innovation;

coverage?

10. Long-term investment

Does the arrangement strengthen or weaken incentives to invest in independent infrastructure?

35. A Useful Analytical Model

Infrastructure convergence can be understood through the following chain:

Infrastructure integration

↓

Economies of scale and scope

↓

Lower costs / increased efficiency

↓

Greater infrastructure utilization

↓

Potential market power

↓

Control over access

↓

Potential vertical or horizontal foreclosure

↓

Effect on downstream competition

↓

Effect on consumers and innovation

This model helps distinguish legitimate infrastructure integration from problematic consolidation.

36. Key Competition Concerns at a Glance

37. Overall Significance of the Case Law

The cases discussed establish several complementary principles:

Terminal Railroad

Control over a bottleneck infrastructure can obstruct downstream competition.

Otter Tail

Infrastructure control can confer leverage into downstream markets.

MCI v AT&T

Interconnection can be essential to competitive access to a network.

Bronner

Compulsory access should not be imposed merely because access is commercially useful.

Microsoft

Control over interoperability information can produce exclusionary effects.

Slovak Telekom

Access conditions themselves can constitute an important competition-law issue.

CK Telecoms

Infrastructure sharing and network structure can materially affect merger analysis and investment incentives.

Iliad Italia

Infrastructure consolidation can be accompanied by access commitments designed to preserve downstream competition.

38. Conclusion

Infrastructure convergence fundamentally changes the way market power should be analysed.

A firm may no longer control merely one infrastructure market. Through convergence it may control a combination of:

physical infrastructure + network infrastructure + data infrastructure + software infrastructure + platform infrastructure.

This creates the possibility of multi-layer market power.

The central competition-law risks are:

infrastructure foreclosure;

discriminatory access;

refusal to supply;

excessive access prices;

margin squeeze;

interoperability restrictions;

self-preferencing;

vertical leveraging;

exclusive dealing;

excessive information exchange;

coordinated infrastructure investment;

anti-competitive infrastructure mergers.

At the same time, infrastructure convergence can produce substantial efficiencies through cost sharing, faster deployment, improved coverage, interoperability and innovation. EU competition principles expressly recognise this dual character of infrastructure sharing: it can promote deployment and efficiency while potentially reducing infrastructure competition if structured improperly. (Eur-Lex)

Accordingly, the appropriate legal approach is not to treat infrastructure convergence itself as anti-competitive. The critical question is whether the converged infrastructure creates a genuine bottleneck and whether its owner uses that position to exclude competitors, discriminate in access, leverage dominance across markets, or weaken the competitive process.

The most useful authorities for this analysis include United States v Terminal Railroad Association, Otter Tail Power v United States, MCI Communications v AT&T, Bronner v Mediaprint, Microsoft v Commission, Slovak Telekom v Commission, CK Telecoms v Commission, and Iliad Italia v Commission. Together they provide a framework covering essential facilities, interconnection, access obligations, interoperability, infrastructure sharing, merger control and downstream foreclosure.
