Arbitration Concerning Telecom Tower Sharing Charge Disagreements

1. Introduction

Telecom tower sharing charge arbitration arises when two or more telecom operators, infrastructure providers, or network companies disagree about the amounts payable for sharing passive or active telecom infrastructure.

The dispute may concern:

tower/site rental;

antenna mounting charges;

electricity and power charges;

diesel-generator costs;

air-conditioning charges;

battery and backup-power costs;

maintenance charges;

additional antenna charges;

additional technology charges;

fibre/backhaul charges;

equipment-space charges;

escalation clauses;

taxes;

security deposits;

minimum guaranteed charges;

decommissioning/exit fees;

retrospective billing;

incorrect invoices;

set-off of disputed amounts; or

whether a particular item of equipment falls within the agreed sharing tariff.

This area is especially important in India because telecom operators frequently use passive infrastructure-sharing arrangements, while regulatory instruments and inter-party contracts may operate simultaneously.

A particularly relevant Supreme Court authority is Bharat Sanchar Nigam Ltd. v. Tata Communications Ltd. (2022), which concerned infrastructure-sharing charges and the effective date of revised rates. The Supreme Court considered the contractual and regulatory framework governing charges for infrastructure used by licensed telecom service providers. (Indian Kanoon)

2. Typical factual scenario

Suppose:

Tower Company A owns 10,000 telecom sites.

Operator B enters into a Passive Infrastructure Sharing Agreement.

The agreement provides:

₹25,000 per site per month;

₹5,000 electricity charge;

additional charge for additional antennas;

annual escalation of 5%;

separate charge for additional technology;

three-year minimum commitment.

After two years, the tower company raises additional invoices claiming:

₹40 crore for additional power consumption and additional LTE equipment.

Operator B disputes the invoices, arguing:

the equipment was already included;

the contract contains an all-inclusive site charge;

the additional technology charge applies only to specified technologies;

the invoices are retrospectively raised;

the tower company cannot unilaterally revise the tariff.

The matter proceeds to arbitration.

The central question becomes:

What charges did the parties actually agree upon, and did the contractual/regulatory framework permit additional or retrospective charges?

3. Nature of telecom infrastructure sharing

Infrastructure sharing can broadly involve:

Passive infrastructure

towers;

poles;

rooftops;

shelters;

cabinets;

power systems;

batteries;

generators;

air-conditioning.

Active infrastructure

radio equipment;

base-station equipment;

antennas;

transmission equipment;

active network components.

Backhaul infrastructure

fibre;

microwave links;

transmission facilities.

The contractual charging methodology differs depending upon the infrastructure being shared.

4. Regulatory framework

In India, telecom sharing operates within a combination of:

licence conditions;

Department of Telecommunications requirements;

TRAI regulations/orders;

interconnection arrangements;

infrastructure-sharing agreements;

commercial tariffs.

The regulatory environment can therefore affect the interpretation of a private agreement.

For example, TRAI's regulatory framework has contemplated circumstances where parties may mutually determine revenue-sharing arrangements and, where agreement cannot be reached, regulatory intervention may follow. (Telecom Regulatory Authority of India)

The tribunal must therefore determine whether the disputed charge is:

purely contractual,

or:

controlled or constrained by a mandatory regulatory framework.

5. First major issue — jurisdiction of the arbitral tribunal

A tower-sharing agreement may contain an arbitration clause such as:

"Any dispute arising out of or relating to this Agreement shall be referred to arbitration."

The dispute may involve:

unpaid charges;

interpretation of tariff;

billing errors;

escalation;

additional equipment;

termination;

exit charges.

These are ordinarily contractual disputes.

However, if one party asks the tribunal to determine the validity of a regulatory tariff or exercise a statutory regulatory function, arbitrability may become more complicated.

6. Booz Allen & Hamilton Inc. v. SBI Home Finance Ltd., (2011) 5 SCC 532

Principle

The Supreme Court distinguished between:

rights in rem; and

rights in personam.

Application

A dispute concerning:

"Whether Operator B owes ₹20 crore under the tower-sharing agreement"

is essentially a contractual dispute concerning rights in personam.

It can generally be referred to arbitration where a valid arbitration agreement exists.

By contrast, a challenge to a statutory regulatory determination may raise different questions concerning the appropriate forum.

Practical significance

A telecom company should frame its claim as:

contractual interpretation + billing + payment

rather than unnecessarily converting the arbitration into a challenge to regulatory policy.

7. Vidya Drolia v. Durga Trading Corporation, (2021) 2 SCC 1

The Supreme Court established the modern framework for determining arbitrability.

The tribunal/court should consider whether the subject matter:

is capable of private adjudication;

is reserved for a statutory forum;

involves rights in rem;

concerns sovereign functions;

has been made non-arbitrable by law.

Tower-sharing application

A disagreement over:

site charges;

electricity costs;

antenna charges;

escalation;

billing;

will ordinarily be suitable for arbitration if covered by the arbitration agreement.

However, the tribunal should not assume that it can exercise every power available to TRAI or another statutory regulator.

8. Bharat Sanchar Nigam Ltd. v. Tata Communications Ltd., Supreme Court, 22 September 2022

This is one of the most directly relevant authorities.

The dispute concerned infrastructure charges payable by licensed telecom service providers to BSNL.

The Supreme Court considered revised infrastructure charges and the question of their effective date.

The underlying framework divided infrastructure-related charges into categories including:

building-space sharing;

electricity and miscellaneous charges;

tower sharing;

duct sharing. (API SCI)

The Court ultimately addressed whether revised rates introduced by BSNL could retrospectively operate from an earlier date or only from the date determined by the regulatory/contractual framework. (Indian Kanoon)

Significance

This case demonstrates that telecom infrastructure charges cannot be analyzed solely as ordinary invoices.

The tribunal must examine:

the applicable regulatory instrument;

the contractual arrangement;

the effective date of revised charges;

whether retrospective recovery is permissible;

whether the parties had agreed to the revised tariff.

Arbitration relevance

Where a tower company says:

"Our revised tariff applies from 2018."

while the operator argues:

"It can apply only prospectively from 2020,"

the reasoning in BSNL v. Tata Communications becomes highly relevant.

9. Reliance Infocomm Ltd. v. Chairman & Managing Director, MTNL, TDSAT, 19 March 2007

This dispute involved infrastructure-sharing charges imposed by MTNL.

The petitioner challenged:

infrastructure charges;

their allegedly arbitrary level;

duplicate charging;

charges imposed for shared equipment;

the basis for determining the charges.

Reliance alleged that the same equipment used for different services had effectively been charged multiple times. (Indian Kanoon)

The case is particularly useful for tower-sharing disputes because it illustrates a recurring problem:

Can the infrastructure owner charge separately for the same physical infrastructure merely because it supports multiple services or technologies?

Arbitration application

Suppose a tower accommodates:

2G;

3G;

4G;

5G.

The tower company claims four separate equipment charges.

The operator argues:

the agreement permits only one site-sharing charge.

The tribunal must examine the contractual definition of:

"equipment";

"technology";

"tenant";

"site";

"sharing unit."

10. ATC Telecom Tower Corporation Pvt. Ltd. v. Videocon Telecommunications Ltd., Delhi High Court, 15 September 2016

This is another highly relevant authority.

The dispute arose under a Passive Infrastructure Sharing Agreement.

ATC claimed substantial outstanding dues, while Videocon had issues concerning its service closure and the resulting financial obligations.

The agreement contained an arbitration mechanism providing for a three-member tribunal. (Indian Kanoon)

Significance

The case demonstrates how tower-sharing agreements can generate disputes concerning:

outstanding site charges;

termination;

exit arrangements;

payment obligations;

arbitration.

Practical lesson

A tower-sharing agreement should expressly address what happens to:

recurring charges;

minimum commitments;

equipment removal;

site restoration;

exit fees;

when the telecom operator shuts down service.

11. McDermott International Inc. v. Burn Standard Co. Ltd., (2006) 11 SCC 181

Principle

Contract interpretation is principally for the arbitral tribunal.

Tower-sharing application

Suppose the agreement states:

"Monthly site rental includes power consumption up to 5 kW."

The operator consumes:

6.5 kW.

The tower company claims an additional amount.

The tribunal must interpret:

"power consumption";

"included";

"additional power";

tariff schedule;

technical annexures.

The tribunal should determine the parties' contractual intention from the agreement as a whole.

12. Nabha Power Ltd. v. Punjab State Power Corporation Ltd., (2018) 11 SCC 508

Principle

Contracts should be interpreted in their commercial context.

Application

A telecom tower agreement is often a long-term commercial arrangement.

If the agreement contains:

basic site rental + power charges + maintenance + escalation,

the tribunal should read the pricing provisions together.

A party should not ordinarily isolate one sentence and ignore:

schedules;

technical specifications;

pricing annexures;

amendments.

13. Alopi Parshad & Sons Ltd. v. Union of India, AIR 1960 SC 588

Principle

An arbitrator cannot rewrite a contract simply because a different outcome appears fairer.

Application

If the tower-sharing contract expressly provides:

5% annual escalation,

the tribunal should not substitute:

10%

merely because electricity or maintenance costs increased substantially.

Similarly, an operator cannot demand elimination of a contractually agreed charge merely because market prices later fell.

14. Associate Builders v. Delhi Development Authority, (2015) 3 SCC 49

Principle

The Supreme Court discussed the permissible grounds for judicial interference with arbitral awards.

Tower-sharing application

Tower-charge disputes frequently require technical evidence concerning:

power consumption;

tower loading;

equipment count;

site capacity;

maintenance costs;

diesel consumption.

If the tribunal evaluates the evidence reasonably and reaches a reasoned conclusion, judicial review should remain limited within the statutory framework.

15. Dyna Technologies Pvt. Ltd. v. Crompton Greaves Ltd., (2019) 20 SCC 1

Principle

An arbitral award should contain sufficient reasoning.

Application

A good tower-charge award should show:

Number of sites = 2,000

Contractual site charge = ₹20,000/month

Contractual monthly charge = ₹4 crore

Additional power charge = ₹40 lakh

Disputed additional equipment charge = ₹15 lakh

Amount already paid = ₹3.8 crore

Net amount due = ₹60 lakh.

This makes the award transparent and enforceable.

16. Ssangyong Engineering & Construction Co. Ltd. v. NHAI, (2019) 15 SCC 131

Principle

Courts have limited grounds for interfering with arbitral awards under the Arbitration and Conciliation Act.

Application

If the tribunal chooses one reasonable interpretation of a tower-sharing tariff after examining:

the agreement;

technical schedules;

invoices;

regulatory materials;

a court should not ordinarily conduct a complete commercial reappraisal merely because another interpretation is possible.

17. Major category of dispute: site rental

The simplest disagreement is:

"How much is payable per site?"

Possible contractual variables include:

urban/rural site;

rooftop/ground-based tower;

macro/micro site;

number of antennas;

number of operators;

tenancy duration;

annual escalation.

Example

Contract:

₹30,000/site/month.

Tower company invoices:

₹35,000/site/month.

It argues:

revised market rates.

Operator responds:

no contractual amendment.

The tribunal will generally prioritize the agreed contractual mechanism.

18. Power charges

Power costs are often more complicated than basic tower rent.

The contract may provide:

actual electricity cost + administration fee.

or:

fixed monthly power charge.

or:

charge based upon metered consumption.

or:

tariff linked to electricity-distribution-company rates.

A dispute may arise because:

meter readings are unavailable;

meters are defective;

consumption is estimated;

diesel consumption is disputed;

multiple operators share the same power system.

19. Diesel-generator disputes

Where grid power is unreliable, the tower site may use:

diesel generators;

batteries;

hybrid power;

solar systems.

The tower company may claim:

₹10 per litre + handling.

The operator may argue:

actual diesel usage was significantly lower.

The tribunal may require:

generator logs;

fuel purchase records;

meter data;

site-level consumption reports.

20. Additional antenna charges

Suppose the agreement permits:

two antennas per tenant.

The operator installs:

four antennas.

The tower company raises additional charges.

The dispute may concern:

whether additional antennas were approved;

whether they increase structural loading;

whether the contract permits additional fees;

whether approval was withheld unreasonably;

whether the charge is per antenna or per installation.

21. Technology charges

This is increasingly important with:

4G;

5G;

Massive MIMO;

small cells;

multiple radio units.

A contract may say:

"Additional technology charge applies for each additional technology deployed."

A dispute can arise where the operator says:

"5G uses existing infrastructure and should not attract a separate charge."

The infrastructure provider may argue:

"The agreement expressly charges per technology."

The tribunal must interpret the contractual definition.

22. BSNL/Jio-type additional technology dispute

The relevance of infrastructure charging has become especially clear from public reporting surrounding BSNL's infrastructure-sharing arrangements.

The CAG has reportedly identified substantial revenue implications associated with BSNL's failure to charge for additional technologies used by another operator under a passive infrastructure-sharing arrangement. (Reddit)

Although an audit finding is not itself an arbitral precedent, it illustrates why contracts should precisely define:

technology;

equipment;

antenna;

BTS;

RRH;

capacity;

additional-tenancy charges.

23. Retrospective billing

This is among the most significant arbitration issues.

Suppose:

2018

Contractual charge = ₹20,000.

2021

Tower company issues revised tariff = ₹25,000.

It then demands:

₹5,000 × 3 years × 5,000 sites.

The operator argues:

retrospective billing is impermissible.

The tower company argues:

the revised tariff was always intended to apply from 2018.

The tribunal should examine:

effective date;

regulatory approval;

contractual amendment;

notice;

acceptance;

past conduct.

The Supreme Court's reasoning in BSNL v. Tata Communications is particularly relevant to disputes concerning the effective date of revised infrastructure charges. (Indian Kanoon)

24. Minimum commitment charges

A tower-sharing contract may require:

minimum annual revenue.

Suppose an operator uses only:

700 sites.

but contractually committed to:

1,000 sites.

The tower company claims payment for all 1,000.

The operator argues:

payment should reflect actual usage.

The tribunal must determine whether the contract establishes:

minimum commitment;

take-or-pay obligation;

actual-use billing;

termination consequences.

25. Exit charges

When an operator leaves a tower:

equipment must be removed;

site must be restored;

records must be updated;

access systems may need modification.

The agreement may impose:

exit fee.

A dispute may arise over whether the exit fee is:

fixed;

cost-based;

liquidated damages;

reimbursement;

penalty.

The tribunal must characterize the clause under the applicable governing law.

26. Duplicate charging

A tower owner may inadvertently charge:

site rent;

antenna rent;

equipment-space charge;

technology charge;

for overlapping infrastructure.

The operator may argue:

"These charges compensate the same underlying facility."

The tribunal should examine whether the charges are:

cumulative;

alternative;

expressly separated.

The Reliance Infocomm v. MTNL dispute is especially instructive on allegations of duplicate charging for shared equipment. (Indian Kanoon)

27. Set-off disputes

Suppose:

Tower company claims

₹50 crore.

Operator claims

₹20 crore service credits.

The tower company deducts the ₹20 crore from amounts otherwise payable.

The operator argues:

unilateral set-off is prohibited.

The tribunal should examine:

contractual set-off clause;

mutuality;

disputed versus admitted amounts;

notice requirements;

billing procedures.

28. Tax and GST

Telecom infrastructure-sharing charges may raise tax questions involving:

GST;

input-tax credits;

withholding;

tax invoices;

changes in tax rates.

The tribunal must distinguish:

contractual price

from

statutory tax component.

If tax is mandatory, a contractual clause should ordinarily be read consistently with applicable tax law.

29. Measurement disputes

Charges may depend on technical measurements:

tower height;

number of antennas;

power consumption;

equipment footprint;

bandwidth;

number of technologies;

number of tenants.

An engineering expert may be necessary.

For example:

Contract permits 3 antenna units.

Operator says:

Tower company says:

6, because each radio unit counts separately.

The answer depends upon the contractual definition of "antenna" or "equipment."

30. Data and billing-system evidence

A sophisticated tower-sharing arbitration may require:

site-management databases;

electronic invoices;

meter data;

GPS/site records;

equipment inventories;

access logs;

energy-management systems.

A party should ideally reconcile:

contract → site list → equipment list → consumption data → invoices → payments.

31. Calculation-agent or billing finality clauses

Some agreements provide that:

invoices generated by the infrastructure provider are final unless disputed within 30 days.

Such a clause can become important.

The tribunal should determine:

Was the invoice challenged on time?

Does the clause bar substantive claims?

Does it apply to obvious errors?

Was the underlying charge legally authorized?

Did the parties waive objections through conduct?

32. Limitation

Tower-sharing relationships can last:

10–15 years.

A billing error may be discovered years later.

Limitation therefore becomes critical.

Questions include:

when did the cause of action arise?

when was the invoice issued?

when was the error discovered?

does an acknowledgment restart limitation?

does continuing billing create separate causes of action?

33. Regulatory change

Telecom regulation can change substantially during a long-term agreement.

For example:

Contract signed in 2014.

New infrastructure-sharing policy introduced in 2018.

New technology deployed in 2020.

5G introduced in 2022.

The parties may disagree about whether the old tariff continues to apply.

The tribunal should examine:

change-in-law clause;

regulatory hierarchy;

modification mechanism;

contractual tariff revision clause.

34. Force majeure

Tower companies sometimes invoke force majeure where costs increase because of:

electricity shortages;

government restrictions;

natural disasters;

fuel shortages;

regulatory changes.

But increased operating costs do not automatically constitute force majeure.

The tribunal must examine the contractual definition.

35. Damages

A successful tower-sharing claimant may seek:

unpaid charges;

contractual interest;

late-payment charges;

costs of restoration;

additional maintenance expenses;

contractual exit fees.

However, consequential losses may be limited by:

liability exclusions;

causation;

remoteness;

mitigation.

36. Interest

Interest can become substantial because telecom disputes often continue for years.

The tribunal should examine:

contractual interest;

pre-reference interest;

pendente lite interest;

post-award interest;

statutory provisions.

The award should clearly identify:

principal + applicable interest period + applicable rate.

37. Evidence matrix

38. Model arbitration dispute

Assume:

10,000 tower sites.

Contractual rent:

₹20,000 per site/month.

Annual escalation:

5%.

The tower company claims:

₹3,000 additional power/site/month.

The operator argues:

actual power costs were already included.

The tower company additionally claims:

₹1,500 per additional 5G technology.

The operator says:

the contract contains no 5G-specific charge.

The tribunal should determine:

Issue 1

Was power separately chargeable?

Issue 2

Was the escalation properly applied?

Issue 3

What constitutes an "additional technology"?

Issue 4

Was 5G within the contractual definition?

Issue 5

Were the charges retrospectively imposed?

Issue 6

Were invoices challenged within the contractual period?

Issue 7

What amount remains outstanding?

39. Possible tribunal outcomes

Outcome A — Tower company succeeds

The contract expressly provides separate charges.

Outcome B — Operator succeeds

The additional charges were not contractually authorized.

Outcome C — Partial award

Some charges are valid, while others are not.

Outcome D — Recalculation

The methodology is correct but the underlying data is wrong.

Outcome E — Regulatory limitation

The contractual tariff is subject to a mandatory regulatory ceiling or methodology.

40. Ten key authorities

41. Most important legal principles

Principle 1 — Contractual tariff governs

Where parties have clearly agreed a tower-sharing tariff, the tribunal ordinarily enforces that tariff.

Principle 2 — Regulatory rules may qualify contractual freedom

A private agreement cannot simply override mandatory telecom regulation.

Principle 3 — Retrospective charges require clear authority

A party seeking several years of additional charges should identify the contractual or regulatory basis for retrospective application.

Principle 4 — Same infrastructure should not automatically generate multiple charges

The contract must determine whether charges are:

per site;

per tenant;

per antenna;

per technology;

per equipment unit.

Principle 5 — Technical evidence matters

A tower-charge arbitration is often partly an accounting and engineering dispute.

Principle 6 — Arbitration cannot replace the regulator

The tribunal may interpret the commercial contract but should not assume statutory powers belonging to the telecom regulator.

42. Recommended arbitral approach

A tribunal should adopt the following sequence:

1. Identify the arbitration agreement

↓

2. Identify the governing law

↓

3. Identify the regulatory framework

↓

4. Identify the type of infrastructure

↓

5. Identify the contractual pricing unit

↓

6. Determine the applicable tariff

↓

7. Determine whether escalation applies

↓

8. Determine whether additional equipment/technology attracts charges

↓

9. Verify site-level data and invoices

↓

10. Determine retrospective applicability

↓

11. Calculate the net outstanding amount

↓

12. Determine interest, costs and other remedies

This approach prevents the tribunal from treating a complex infrastructure-sharing relationship as merely an unpaid-invoice case.

43. Conclusion

Telecom tower-sharing charge arbitration is fundamentally a contractual pricing dispute operating within a regulated telecommunications environment.

The strongest cases generally turn on five questions:

What infrastructure was shared?

What pricing formula did the parties agree?

Did the regulatory framework modify or constrain that formula?

Were the disputed charges properly calculated and timely raised?

Was any revised tariff legally and contractually effective from the date claimed?
