1. Introduction

Energy projects are rarely undertaken by a single entity. A power plant, transmission line, renewable-energy facility, offshore wind farm, battery-storage project, or hydrogen facility normally involves a project owner, developer, EPC contractor, subcontractors, equipment suppliers, lenders, operators, consultants, insurers, grid operators and public authorities. Because several parties contribute to the same project, an important legal question arises: who bears responsibility when something goes wrong?

“Liability allocation among project participants” refers to the legal mechanisms through which responsibility for delay, defective construction, equipment failure, environmental harm, regulatory non-compliance, safety incidents, cost overruns, performance shortfalls and third-party losses is distributed among participants.

The allocation generally depends on a combination of contract law, tort law, statutory duties, regulatory licences, project agreements, insurance arrangements and principles of causation and contribution.

2. Why Liability Allocation Matters

Large energy projects involve significant technical, financial and regulatory risks. For example:

• An EPC contractor may construct a defective generating unit.
• An equipment manufacturer may supply defective turbines.
• A project company may fail to obtain a required environmental approval.
• An operator may negligently maintain equipment.
• A grid operator may fail to provide an agreed connection.
• A subcontractor may cause a workplace accident.
• A developer may fail to achieve contractual commissioning dates.

Without clearly allocated responsibility, disputes can arise over whether the loss should be borne by the project company, contractor, supplier, operator, insurer or another participant.

The principal objectives of liability allocation are therefore:

1. identifying the party best positioned to control a risk;
2. preventing duplication of liability;
3. establishing contractual remedies;
4. protecting lenders and investors;
5. ensuring compensation for affected third parties;
6. complying with mandatory statutory duties; and
7. providing certainty regarding project costs.

3. Contractual Allocation of Liability

The most important mechanism is usually the contractual structure.

Energy projects commonly contain:

• EPC contracts
• Power Purchase Agreements (PPAs)
• Operation and Maintenance Agreements
• Engineering and consultancy agreements
• Equipment supply agreements
• Grid connection agreements
• Concession agreements
• Joint-venture agreements
• Shareholder agreements
• Government support agreements

Each agreement allocates particular risks.

Example

Suppose a solar project suffers a substantial generation loss because panels supplied by a manufacturer are defective.

The project company may have:

• contractual performance guarantees against the supplier;
• warranty claims;
• liquidated damages provisions;
• insurance coverage; and
• potentially claims against an EPC contractor if the EPC contractor was responsible for procurement and integration.

The precise allocation depends on the contractual chain.

4. EPC Contractor Liability

In an EPC contract, the contractor generally undertakes responsibility for designing, procuring and constructing the facility.

Typical contractor liabilities include:

A. Design defects

If the contractor is responsible for design and the facility fails because of defective engineering, the contractor may be liable for resulting losses.

B. Construction defects

Poor workmanship can create liability for:

• repair costs;
• replacement costs;
• delay;
• lost production;
• safety incidents.

C. Delay

Contracts frequently establish liquidated damages for failure to achieve contractual milestones.

D. Performance failure

Energy projects commonly include performance tests.

For example, a power plant may have contractual requirements relating to:

• capacity;
• heat rate;
• efficiency;
• availability;
• output;
• emissions.

Failure may trigger contractual damages.

5. Equipment Manufacturer Liability

Equipment suppliers may bear responsibility for defects in:

• turbines;
• transformers;
• generators;
• solar modules;
• batteries;
• inverters;
• control systems.

Liability is often governed by warranties and performance guarantees.

A critical issue is the distinction between manufacturer liability to the purchaser and liability to third parties.

A manufacturer may have contractual liability to the project company while third-party liability may arise independently under tort or statutory law.

6. Subcontractor Liability

An EPC contractor frequently employs subcontractors.

A common contractual structure is:

Project Company → EPC Contractor → Subcontractor

The project company normally seeks to preserve a single point of responsibility by making the EPC contractor responsible for subcontractor performance.

Thus, although a subcontractor may have caused the physical defect, the project company may pursue the EPC contractor under the EPC agreement.

The EPC contractor can subsequently seek indemnification or contribution from the subcontractor.

This structure prevents the owner from having to pursue numerous subcontractors separately.

7. Operator Liability

After commissioning, operational risks become particularly important.

An O&M contractor may be responsible for:

• maintenance;
• operational errors;
• failure to follow technical procedures;
• failure to meet availability guarantees;
• negligent maintenance;
• unsafe operation.

For example, if negligent maintenance causes a turbine failure, the operator may bear contractual responsibility subject to agreed exclusions and liability caps.

However, the project owner may retain certain risks, particularly risks that cannot legally be transferred.

8. Project Company Liability

The Special Purpose Vehicle (SPV) generally owns and operates the project.

The SPV may therefore bear responsibility for:

• regulatory compliance;
• permits;
• environmental obligations;
• land rights;
• financing obligations;
• PPA obligations;
• grid obligations;
• employment and workplace duties;
• third-party claims.

The use of an SPV does not mean that all project risks disappear. Limited liability generally protects shareholders from direct exposure beyond their investment, but statutory duties and contractual obligations remain applicable to the project company.

9. Joint and Several Liability

One of the most important questions is whether participants are:

• jointly liable;
• severally liable; or
• liable according to their respective shares of responsibility.

Where joint and several liability applies, an injured party may potentially recover the full amount from one liable participant, leaving that participant to pursue contribution from other responsible parties.

This is particularly significant in construction and infrastructure disputes because several participants may contribute to the same loss.

10. Indemnities

Indemnity clauses are frequently used to redistribute liability.

For example:

The contractor may indemnify the project company against third-party claims arising from the contractor's negligence.

Indemnities can address:

• bodily injury;
• property damage;
• intellectual property infringement;
• environmental claims;
• tax liabilities;
• regulatory penalties where legally permissible;
• subcontractor claims.

However, indemnities must be interpreted carefully because courts generally examine the actual wording of the clause.

11. Limitation and Exclusion Clauses

Energy contracts often contain liability caps.

For example:

Contractor's aggregate liability shall not exceed 100% of the contract price.

There may also be exclusions for:

• consequential loss;
• loss of profit;
• loss of revenue;
• loss of production;
• indirect damages.

However, these clauses may not protect a party against every form of liability.

Mandatory statutory duties, fraud, wilful misconduct, certain environmental obligations and some forms of personal injury may be treated differently depending on the applicable jurisdiction.

12. Liquidated Damages

Liquidated damages provide a predetermined mechanism for compensation.

For example, an EPC agreement may provide:

Delay damages = ₹X per day of delay

This provides greater certainty than requiring the owner to prove actual losses.

In energy projects, liquidated damages commonly cover:

• construction delay;
• delayed commissioning;
• failure to achieve performance guarantees;
• failure to meet availability requirements.

The legal enforceability of such clauses depends upon the applicable law and whether the provision is viewed as a genuine contractual allocation of loss or an unenforceable penalty.

13. Force Majeure

Participants usually distinguish risks within their control from extraordinary external events.

Force majeure provisions may cover:

• natural disasters;
• war;
• governmental action;
• epidemics;
• extreme weather;
• grid-wide emergencies;
• certain supply-chain disruptions.

A force majeure clause can excuse contractual non-performance if its requirements are satisfied.

However, economic difficulty alone does not automatically establish force majeure. The wording of the contract and the causal connection between the event and the failure are critical.

14. Insurance as a Liability Allocation Mechanism

Insurance supplements contractual allocation.

Common project insurance includes:

• Construction All Risks insurance;
• Delay in Start-Up insurance;
• operational all-risk insurance;
• machinery breakdown insurance;
• third-party liability insurance;
• marine cargo insurance;
• environmental liability insurance.

Insurance does not necessarily eliminate legal liability. Instead, it provides a financial mechanism for absorbing specified risks.

15. Environmental Liability

Energy projects create particular environmental risks.

Potential liabilities include:

• pollution;
• land contamination;
• water contamination;
• biodiversity damage;
• hazardous-material releases;
• unlawful emissions.

Environmental liability can arise independently of contractual arrangements.

Consequently, a project participant cannot always avoid statutory environmental responsibility merely by transferring contractual responsibility to another participant.

16. Regulatory Liability

Energy-sector participants also operate within regulatory frameworks.

A generating company may be required to comply with:

• electricity licensing requirements;
• grid codes;
• environmental regulations;
• safety requirements;
• emissions standards;
• market rules.

A contract cannot necessarily transfer a statutory obligation imposed directly upon a licensee.

This creates an important distinction:

Contractual allocation ≠ regulatory allocation.

A project company may contractually transfer performance responsibilities to an EPC or O&M contractor, but the regulator may continue to hold the licensed entity responsible.

17. Indian Legal Framework

In India, liability allocation in energy projects may involve several bodies of law, including:

• Indian Contract Act, 1872
• Specific Relief Act, 1963
• Electricity Act, 2003
• Environment (Protection) Act, 1986
• Water Act, 1974
• Air Act, 1981
• Consumer Protection Act, 2019, where applicable
• principles of tort law
• arbitration law
• sector-specific regulations.

The Indian Contract Act, 1872 is particularly important because EPC, supply, O&M and other project agreements are primarily contractual arrangements.

18. Important Indian Case Law

A. Energy Watchdog v. CERC (2017)

The Supreme Court considered the relationship between contractual obligations, force majeure and regulatory intervention in the context of power purchase agreements.

The Court examined whether changes in circumstances affecting coal supply could excuse contractual performance.

The case is important because it demonstrates that commercial difficulty and changes in circumstances do not automatically justify departure from contractual obligations. The contractual force-majeure provisions and the statutory framework must be examined carefully.

Importance for liability allocation:
Project participants must clearly identify which external risks are allocated to the generator, purchaser or another participant.

B. Central Inland Water Transport Corporation Ltd. v. Brojo Nath Ganguly (1986)

The Supreme Court examined unconscionable contractual terms and unequal bargaining power.

Although not an energy-project case, its principles are relevant to project contracts because sophisticated infrastructure agreements can contain extensive exclusion and limitation clauses.

Importance:
Contractual freedom is important, but contractual provisions may be scrutinised where broader principles of public policy and unconscionability become relevant.

C. ONGC Ltd. v. Saw Pipes Ltd. (2003)

The Supreme Court dealt extensively with liquidated damages and contractual compensation.

The case is significant for infrastructure contracts because it demonstrates the importance of contractual provisions governing delay and compensation.

Importance for energy projects:
EPC agreements should specify measurable consequences for delay and performance failure rather than leaving every dispute to uncertain damages litigation.

D. Kailash Nath Associates v. Delhi Development Authority (2015)

The Supreme Court clarified principles concerning compensation and forfeiture under Section 74 of the Indian Contract Act.

The decision is relevant to project agreements containing predetermined damages or forfeiture mechanisms.

Importance:
The mere existence of a contractual damages clause does not mean that every claimed amount will automatically be recoverable.

E. Ssangyong Engineering & Construction Co. Ltd. v. NHAI (2019)

This arbitration case is particularly relevant to infrastructure projects.

The Supreme Court examined the scope of judicial intervention in arbitral awards and the limits of contractual interpretation in infrastructure disputes.

Importance:
Because major energy projects frequently use arbitration, the case demonstrates the importance of precise contractual drafting and the relationship between contractual risk allocation and arbitral decision-making.

19. English Case Law Relevant to Energy and Infrastructure Projects

Hadley v Baxendale (1854)

This foundational case established principles concerning recoverability of contractual damages.

Loss must generally fall within the appropriate scope of foreseeable contractual consequences.

Energy-project significance:
A project participant cannot automatically recover every economic consequence arising from another party's breach.

Transfield Shipping Inc. v Mercator Shipping Inc. (The Achilleas) (2008)

The House of Lords reconsidered the principles governing remoteness of contractual damages.

The case is particularly useful in understanding how parties' assumed responsibility affects recoverable losses.

Project significance:
Parties should clearly identify which categories of economic loss they intend to allocate contractually.

MT Højgaard A/S v E.ON Climate & Renewables UK Robin Rigg East Ltd (2017)

This is especially important for energy infrastructure.

The dispute concerned defects associated with foundations used in an offshore wind project.

The UK Supreme Court examined the relationship between contractual technical requirements and performance obligations.

The case illustrates an important principle: careful drafting is essential where technical specifications, industry standards and performance obligations coexist.

For renewable-energy projects, it is highly relevant to the allocation of design and engineering risk.

20. Liability Matrix

A project can use a liability matrix to allocate responsibility:

The matrix should be integrated with the project's contracts rather than treated as a standalone document.

21. Direct and Indirect Liability

A critical distinction exists between direct liability and pass-through liability.

Direct liability

The project owner suffers a loss directly because of the contractor's breach.

Pass-through liability

The owner incurs a liability to a third party and seeks to recover that amount from the contractor.

For example:

Subcontractor negligence → EPC contractor liability → project company loss

The EPC contract may allow the project company to recover the resulting amount from the EPC contractor.

22. Causation and Contribution

When multiple parties contribute to a loss, courts and arbitral tribunals may have to determine:

1. Who breached a duty?
2. Was the breach causally connected to the loss?
3. Did another participant contribute?
4. Was there contributory negligence?
5. Was the loss foreseeable?
6. Is the claimed loss contractually recoverable?
7. Is liability limited by an exclusion or cap?

This makes causation central to energy-project disputes.

23. Lender Considerations

Project-finance lenders are particularly interested in liability allocation.

They may require:

• direct agreements;
• assignment of warranties;
• step-in rights;
• performance guarantees;
• completion guarantees;
• insurance;
• parent-company guarantees;
• liquidated damages;
• security packages.

The objective is to ensure that a project failure does not leave the SPV without meaningful contractual remedies.

24. Dispute Resolution

Energy projects frequently use:

• arbitration;
• expert determination;
• dispute adjudication boards;
• mediation;
• courts.

Technical disputes may be particularly suitable for expert determination, while major contractual disputes may proceed to arbitration.

The dispute-resolution mechanism itself therefore forms part of effective liability allocation.

25. Key Principles

Effective liability allocation should follow several principles:

1. Allocate risk to the party best able to control it

Construction risk should ordinarily be allocated to the party responsible for construction.

2. Avoid conflicting obligations

Technical specifications should not contradict performance guarantees.

3. Clearly define loss

Terms such as “consequential loss,” “indirect loss,” “loss of profit,” and “loss of production” should be carefully defined.

4. Coordinate contracts

The EPC, PPA, supply agreement, O&M agreement and financing documents should operate consistently.

5. Protect third parties

Contractual allocation should not undermine mandatory statutory protections.

6. Align insurance with contractual responsibility

An uninsured contractual risk can create serious financial exposure.

26. Conclusion

Liability allocation among project participants is a central component of modern energy-project governance. Energy projects involve interconnected contractual and regulatory relationships, meaning that responsibility cannot be determined solely by asking who physically caused an incident.

The principal mechanisms include EPC contracts, warranties, performance guarantees, indemnities, liquidated damages, liability caps, insurance, force-majeure provisions, statutory duties and dispute-resolution mechanisms.

The case law demonstrates the importance of precise drafting. Energy Watchdog highlights the significance of contractual force-majeure allocation; ONGC v. Saw Pipes and Kailash Nath Associates demonstrate the importance of contractual damages provisions; while MT Højgaard v. E.ON illustrates the special importance of reconciling technical specifications with contractual performance obligations in energy infrastructure.

Ultimately, an effective liability structure seeks to place each risk with the participant best positioned to prevent, manage, insure against, or financially absorb that risk, while recognising that contractual allocation cannot necessarily override mandatory statutory or regulatory responsibilities.
