ENERGY LAW AND CROSS-BORDER CLEAN ELECTRICITY TRADE

Introduction

Cross-border clean electricity trade refers to the import and export of electricity generated from renewable or other low-carbon sources between two or more countries through interconnected transmission networks. It is an important component of the modern energy transition because countries may possess different levels of renewable-energy resources, generation capacity, electricity demand, and grid flexibility. Cross-border electricity trade allows surplus clean electricity generated in one jurisdiction to be supplied to consumers in another jurisdiction.

The legal framework governing such trade combines energy regulation, electricity-market rules, international trade law, environmental law, transmission regulation, investment law, and bilateral or regional agreements. Electricity is also treated as a good under the Harmonized System, and WTO materials recognize electricity under tariff heading 2716.

India provides an important regional example. The Ministry of Power issued the Guidelines for Import/Export (Cross Border) of Electricity, 2018, while the Central Electricity Regulatory Commission subsequently issued the CERC (Cross Border Trade of Electricity) Regulations, 2019. These instruments seek to facilitate cross-border electricity trade while maintaining grid reliability and regulatory transparency.

1. Meaning and Scope

Cross-border clean electricity trade occurs when electricity crosses an international boundary through transmission infrastructure. The electricity may be generated by:

Solar power;

Wind power;

Hydropower;

Geothermal energy;

Biomass or other renewable sources; or

Other low-carbon generation technologies where recognized by the applicable regulatory framework.

The transaction normally involves a generator, trader or market participant, transmission-system operators, regulators, and consumers or distribution companies.

Unlike ordinary trade in physical goods, electricity cannot ordinarily be stored economically at large scale in the transmission network. Consequently, cross-border electricity trade requires real-time coordination of generation, transmission capacity, balancing, scheduling and system security.

2. Major Legal Issues

A. Market Access

A central issue is whether foreign electricity producers and traders are legally permitted to access the importing country's electricity market.

A discriminatory or state-controlled import system may restrict competition. European Union jurisprudence has historically treated electricity as falling within the rules concerning free movement of goods. In Almelo v. Energiebedrijf IJsselmij NV (Case C-393/92), the European Court of Justice dealt with restrictions surrounding electricity supply and emphasized the interaction between electricity monopolies and European competition/free-movement principles.

The principle became particularly important in the development of an integrated European electricity market.

B. Transmission Access

Cross-border electricity trade depends upon access to interconnectors and transmission networks. Legal rules therefore need to establish:

third-party access;

transmission capacity allocation;

congestion management;

transmission charges;

priority rules;

balancing responsibilities; and

emergency curtailment procedures.

GATT Article V and energy-specific international arrangements have also raised questions concerning the legal treatment of energy transit through fixed infrastructure such as electricity grids. WTO research has specifically examined whether electricity transit through grids can fall within international transit disciplines.

C. Grid Reliability and Security

Electricity systems operate as interconnected physical networks. A transaction that is commercially lawful may nevertheless be restricted if it threatens system stability.

Cross-border rules therefore commonly require:

frequency control;

reserve capacity;

balancing arrangements;

outage coordination;

emergency assistance;

cybersecurity protection;

technical standards; and

coordinated system operation.

India's 2018 cross-border guidelines expressly identify reliable grid operation and transmission of electricity for import/export as an objective.

D. Renewable-Energy Certification

Clean electricity trade creates an important legal question: how can the importing country verify that imported electricity is genuinely renewable?

Legal systems may use:

guarantees of origin;

renewable-energy certificates;

power-purchase agreements;

tracking systems;

metering requirements; and

contractual environmental attributes.

Without reliable certification, the same renewable attribute could potentially be claimed in more than one jurisdiction, creating the risk of double counting.

E. Climate and Environmental Regulation

Cross-border clean electricity trade is increasingly connected with national climate targets. Governments may give preferential treatment to electricity satisfying renewable or low-carbon standards.

However, environmental requirements must be designed consistently with applicable trade obligations. WTO jurisprudence demonstrates that renewable-energy measures can raise questions concerning non-discrimination, domestic-content requirements and subsidies.

For example, in Canada – Renewable Energy / Feed-In Tariff (DS412 and DS426), WTO adjudicators examined Ontario's renewable-energy procurement programme and its domestic-content requirements. The dispute demonstrates that renewable-energy policies can interact with international trade disciplines.

Similarly, in India – Certain Measures Relating to Solar Cells and Solar Modules (DS456), the WTO dispute settlement bodies found India's domestic-content requirements inconsistent with certain GATT and TRIMs obligations.

These cases are not direct cross-border electricity-import cases, but they establish important legal principles concerning the design of clean-energy trade policies.

3. Indian Legal Framework

India has progressively developed a legal framework for cross-border electricity trade with neighbouring countries.

The Ministry of Power's 2018 Guidelines for Import/Export (Cross Border) of Electricity were designed to facilitate electricity trade with neighbouring countries and promote transparent, consistent and predictable regulation. The framework also provides for a designated authority responsible for facilitating approvals and procedures.

India has developed or pursued electricity interconnections with countries including Bhutan, Bangladesh and Nepal. Government materials identify interconnection projects involving India-Nepal, India-Bangladesh and India-Bhutan transmission links.

The CERC (Cross Border Trade of Electricity) Regulations, 2019 further establish the regulatory framework for cross-border transactions.

4. Important Case Laws

1. Almelo v. Energiebedrijf IJsselmij NV, Case C-393/92

Facts: The dispute concerned contractual restrictions and electricity supply within the Dutch electricity system.

Principle: The Court examined electricity within the framework of European Community competition and market rules.

Importance: The case is significant for demonstrating that electricity markets cannot automatically be insulated from broader rules governing competition and market integration.

2. Commission v Netherlands, Case C-157/94

Facts: The Netherlands maintained arrangements giving a national electricity undertaking exclusive rights relating to electricity imports.

Judgment: The European Court of Justice examined the compatibility of such arrangements with European Community law governing trade and competition.

Importance: The case illustrates the legal tension between national electricity monopolies and cross-border electricity-market integration. The Court's electricity-import/export monopoly litigation also covered Italy, France and Spain.

3. Commission v Italy, Case C-158/94

Facts: Italy had historically entrusted electricity activities, including import and export, to ENEL.

Principle: The Court examined national electricity-import/export monopolies against European Community obligations.

Importance: It demonstrates that state control over electricity imports can be subject to supranational market rules.

4. Canada – Renewable Energy / Feed-In Tariff, DS412 and DS426

Facts: Ontario's renewable-energy programme included domestic-content requirements.

Finding: WTO adjudicators examined whether the measures discriminated against imported renewable-energy equipment and whether government procurement exceptions applied.

Importance: The case establishes that clean-energy policies must be carefully designed in light of international trade obligations.

5. India – Solar Cells, DS456

Facts: India imposed domestic-content requirements under its solar-energy programme.

Finding: WTO adjudicators found relevant measures inconsistent with certain GATT and TRIMs obligations.

Importance: The case demonstrates that renewable-energy promotion cannot automatically justify discriminatory treatment of foreign products.

6. EU – Certain Measures Relating to the Energy Sector, DS476

Facts: Russia challenged various measures associated with the EU Third Energy Package.

Issues: The dispute involved GATT, GATS and subsidy-related claims concerning regulation of the European energy sector.

Importance: Although not a pure electricity-trade case, it demonstrates how international trade law can interact with cross-border energy-market regulation and infrastructure access.

7. Aquind v. ACER, Case T-342/23

Facts: The case concerned a proposed electricity interconnector between the United Kingdom and France and actions associated with EU energy regulation.

Importance: The General Court's 2025 judgment demonstrates the significance of EU regulatory decisions affecting cross-border electricity interconnection projects.

5. Cross-Border Power Purchase Agreements

Long-term Power Purchase Agreements (PPAs) can support clean-electricity trade by providing predictable revenue to renewable-energy projects.

A cross-border PPA should address:

governing law;

delivery point;

transmission responsibility;

renewable attributes;

currency and payment mechanisms;

curtailment;

force majeure;

change in law;

political risk;

transmission congestion;

imbalance charges;

environmental compliance; and

dispute resolution.

The contract must also coordinate with the regulatory rules of both the exporting and importing jurisdictions.

6. Role of International Trade Law

Electricity trade may engage WTO rules because electrical energy is classified under HS heading 2716. WTO materials note that electricity has been treated as a good for international trade purposes.

Relevant principles can include:

Most-Favoured-Nation treatment;

National Treatment;

quantitative restrictions;

subsidies;

technical regulations;

customs treatment; and

transit.

Nevertheless, electricity has unique physical characteristics, meaning that ordinary trade rules must operate alongside specialized energy regulation. WTO literature specifically recognizes the distinctive characteristics of energy trade and the challenges of applying general trade disciplines to the sector.

7. Challenges in Cross-Border Clean Electricity Trade

The major legal and regulatory challenges include:

Different electricity-market structures;

Conflicting national energy-security policies;

Transmission congestion;

Grid instability;

Different renewable-energy definitions;

Double counting of renewable attributes;

Cross-border taxation;

Currency and payment risk;

Political and regulatory changes;

Disputes concerning transmission capacity;

Cybersecurity risks; and

Differences in environmental standards.

These issues require coordination between national regulators and transmission-system operators.

Conclusion

Cross-border clean electricity trade is an important legal mechanism for integrating renewable-energy resources across national boundaries. Its success depends not merely on commercial contracts but on a coordinated legal framework covering market access, transmission, grid reliability, renewable certification, environmental standards, international trade law, investment protection and dispute resolution.

For India, the 2018 Cross-Border Electricity Trade Guidelines and the CERC 2019 Regulations provide an important regulatory foundation for electricity exchange with neighbouring countries. International and comparative jurisprudence, particularly European electricity-market cases and WTO renewable-energy disputes, demonstrates that clean-energy objectives must operate alongside principles of non-discrimination, competition, market access and regulatory transparency.

Therefore, the future of cross-border clean electricity trade lies in developing interconnected regional grids, transparent transmission-access rules, credible renewable-energy certification, coordinated regulatory institutions and legally enforceable cross-border agreements.
