1. Introduction

Local Energy Markets (LEMs) are decentralised electricity-market arrangements in which electricity generated, stored, consumed, or managed by participants within a defined geographical area can be traded or allocated locally. Participants may include households, rooftop-solar prosumers, community-energy organisations, battery operators, electric-vehicle owners, commercial consumers, aggregators and distribution utilities.

Unlike the traditional electricity model—where electricity generally flows from large generators through transmission and distribution networks to consumers—local energy markets facilitate two-way participation. A consumer may simultaneously become a producer, or prosumer, and may sell surplus electricity to another consumer through a regulated platform.

A particularly important development is peer-to-peer (P2P) electricity trading. Delhi's 2024 P2P Guidelines define a P2P transaction as a marketplace in which consumers and prosumers transact electricity through an interconnected platform, including blockchain or other technology. Derc

The legal challenge is that electricity is not merely an ordinary commodity. Trading must coexist with rules governing licensing, grid operation, consumer protection, tariffs, balancing, metering, network charges, renewable-energy obligations, market competition and system security.

2. Meaning of a Local Energy Market

A local energy market can be understood as:

A regulated market mechanism through which electricity or electricity-related services are traded among participants connected to a local distribution network, generally using digital platforms and distributed energy resources.

The principal participants are:

(a) Prosumers

A prosumer both consumes and produces electricity—for example, a household with rooftop solar.

(b) Consumers

Consumers purchase electricity from a local market, utility, aggregator or another participant.

(c) Distributed Energy Resources

These include:

• rooftop solar;
• small wind systems;
• batteries;
• electric vehicles;
• demand-response systems;
• small-scale generators;
• microgrids.

(d) Aggregators

Aggregators combine multiple small resources and participate in electricity markets on behalf of consumers and prosumers.

(e) Distribution System Operators

The distribution network remains essential because locally traded electricity normally requires physical use of the electricity network.

(f) Market/platform operators

A digital platform can match buyers and sellers, calculate prices, record transactions and communicate schedules to the relevant distribution utility.

3. Local Energy Markets versus Traditional Electricity Markets

The distinction is not absolute. A local market generally remains physically dependent on the regulated distribution system.

This is why local trading cannot simply be treated as an unregulated private contract between two electricity users.

4. Legal Foundations of Local Energy Markets

A functioning LEM normally requires legal rules dealing with at least eight areas.

4.1 Market participation

Law must determine who can participate:

• generators;
• consumers;
• prosumers;
• aggregators;
• energy communities;
• traders;
• distribution licensees.

The EU Electricity Directive 2019/944, for example, requires citizen energy communities to have access to electricity markets, directly or through aggregation, on a non-discriminatory basis. EUR-Lex

4.2 Licensing

A central legal question is:

Does a person selling electricity locally become an electricity supplier or trader requiring a licence?

This is especially important in India.

The Electricity Act, 2003 separates activities such as generation, transmission, distribution and trading. Consequently, a regulatory framework for P2P trading has to determine whether the platform is merely providing technological services or is legally participating in electricity supply/trading.

This distinction prevents an online platform from unintentionally becoming an unlicensed electricity distribution business.

5. Local Energy Trading in India

India provides an important emerging example.

The Electricity Act, 2003, particularly its provisions concerning electricity markets, trading and regulatory powers, provides the broader legal framework. Section 66 directs the appropriate Commission to promote the development of a market for electricity.

The development of power exchanges demonstrates that electricity can be traded through organised market mechanisms, but local energy markets introduce an additional problem: transactions may occur between relatively small distributed producers and consumers connected to the same distribution network.

Delhi P2P framework

The Delhi Electricity Regulatory Commission adopted Peer-to-Peer Energy Transaction Guidelines in 2024.

The Guidelines contemplate a P2P platform operated by a service provider or DISCOM and define P2P transactions as transactions through an interconnected marketplace involving consumers and prosumers. Derc

Importantly, the subsequent DERC proceedings clarify that P2P transactions remain within the existing electricity regulatory framework and that electricity continues to be supplied through the distribution utility. The Guidelines initially focused on transactions between prosumers and consumers within the same DISCOM area. Derc

This illustrates an important principle:

Digital trading does not eliminate the legal and physical role of the distribution licensee.

6. Physical Electricity and Virtual Trading

One of the most important concepts in local energy markets is the distinction between:

Physical electricity flow

Electricity actually moves through the distribution network.

Financial/contractual transaction

A digital platform records that one participant sold electricity to another.

Electricity cannot ordinarily be directed through the grid in the same way that a parcel can be sent from one house to another.

Therefore, a P2P platform generally performs market matching and financial settlement, while the physical electricity continues to be managed by the network operator.

This raises questions concerning:

• network charges;
• losses;
• balancing;
• congestion;
• metering;
• scheduling;
• settlement;
• system security.

7. Local Market Clearing

A local energy market needs a mechanism for matching supply and demand.

Suppose:

• Solar Producer A offers 100 kWh at ₹5/kWh.
• Consumer B wants 60 kWh at up to ₹6/kWh.
• Consumer C wants 40 kWh at up to ₹5.50/kWh.

A market platform can match the offers and determine a clearing price.

Possible mechanisms include:

Pay-as-bid

Each successful seller receives its offered price.

Uniform-price clearing

All accepted sellers receive the market-clearing price.

Locational pricing

Prices reflect local network constraints.

Dynamic pricing

Prices change according to real-time supply and demand.

The legal framework must establish who is authorised to operate the market and how price discovery is supervised.

8. Local Congestion Management

Local markets can create a paradox.

Suppose a neighbourhood has:

• 500 rooftop-solar systems;
• low daytime demand;
• a distribution transformer with limited capacity.

If everyone exports electricity simultaneously, the network may become congested even though sufficient electricity exists locally.

Therefore, LEM legislation may need mechanisms for:

• export limits;
• flexible connection agreements;
• local congestion prices;
• demand response;
• battery dispatch;
• curtailment;
• network reinforcement.

This means local market design must combine economic efficiency with physical network constraints.

9. Balancing Responsibility

Electricity supply and demand must remain balanced.

If a P2P seller promises to deliver 10 kWh but produces only 7 kWh, someone must manage the resulting imbalance.

Possible arrangements include:

1. individual balance responsibility;
2. aggregator responsibility;
3. DISCOM responsibility;
4. market operator responsibility.

The EU framework expressly recognises this issue. Citizen energy communities must be financially responsible for the imbalances they cause, either becoming balance-responsible parties or delegating balancing responsibility. EUR-Lex

This principle is highly relevant to future Indian LEM regulation.

10. Network Charges

A major legal issue is:

If two consumers trade electricity locally, should they pay the same network charges as ordinary electricity consumers?

Even when electricity is generated nearby, the network may still provide:

• physical infrastructure;
• metering;
• protection;
• balancing;
• backup;
• system operation.

Therefore, eliminating network charges completely could shift costs onto other consumers.

The EU Electricity Directive recognises that energy-community electricity sharing remains subject to applicable network charges, tariffs and levies, while requiring transparent and non-discriminatory treatment. EUR-Lex

11. Consumer Protection

Local energy markets create new legal risks.

Consumers need protection against:

• misleading prices;
• hidden fees;
• inaccurate meters;
• discriminatory access;
• unreliable platforms;
• cyberattacks;
• manipulation of transactions;
• unfair contractual conditions.

A P2P platform therefore should ordinarily provide:

• transparent pricing;
• clear contracts;
• accessible complaint mechanisms;
• data protection;
• transaction records;
• dispute-resolution mechanisms.

12. Smart Meters and Data Governance

Local energy trading requires detailed measurement.

Smart meters can record:

• electricity imported;
• electricity exported;
• time of consumption;
• generation;
• battery charging;
• battery discharge.

This produces commercially and potentially personally sensitive information.

Consequently, LEM regulation must address:

• ownership of meter data;
• access rights;
• cybersecurity;
• privacy;
• data-sharing;
• consent;
• interoperability.

A blockchain platform does not remove these legal obligations.

13. Blockchain-Based Local Energy Trading

Blockchain can potentially provide:

• transaction records;
• automated settlement;
• smart contracts;
• identity management;
• transparent transaction histories.

For example:

Solar prosumer → blockchain platform → consumer → smart meter → settlement

However, blockchain cannot independently determine:

• whether electricity was physically delivered;
• whether a participant is licensed;
• whether grid capacity exists;
• whether tariffs are lawful.

Thus:

Technological decentralisation does not necessarily produce legal decentralisation.

The underlying electricity network remains subject to public regulation.

14. Energy Communities

Energy communities are closely connected to LEMs.

An energy community may collectively:

• own solar generation;
• operate batteries;
• purchase electricity;
• sell electricity;
• participate in demand response;
• share energy among members.

EU law expressly provides a regulatory framework for citizen energy communities and requires participation to be open and voluntary, while protecting members' rights as electricity customers. EUR-Lex

This represents a legal shift from purely commercial electricity markets toward participatory energy governance.

15. Important Case Law

Case 1: Bursa Română de Mărfuri SA v ANRE, C-394/21

This 2023 CJEU judgment concerned electricity-market trading and a national legal monopoly over electricity trading services.

The Court considered the relationship between national trading arrangements and EU electricity-market principles. EUR-Lex

Relevance to local energy markets

The case demonstrates that electricity trading markets are subject to:

• competition principles;
• market-access requirements;
• EU electricity-market rules;
• proportionality of national restrictions.

For local markets, this suggests that governments must carefully justify exclusive market structures rather than automatically granting one platform absolute control.

Case 2: Hidroelectrica, C-648/18

The CJEU examined Romanian legislation requiring electricity producers to sell electricity through platforms operated by the designated national electricity-market operator.

The Court concluded that requiring producers to offer all available electricity through the sole designated platform went beyond what was necessary to achieve the relevant objective and infringed EU free-movement principles. EUR-Lex

Importance

The case establishes an important regulatory principle:

Electricity-market regulation must balance market transparency and security with competition and proportionality.

For LEMs, excessive platform exclusivity could raise similar legal questions.

Case 3: ENGIE Deutschland GmbH v Landesregulierungsbehörde, C-293/23

The CJEU decided this case on 28 November 2024.

It concerned an electricity system serving residential buildings and the question of whether its operator could avoid obligations applicable to distribution-system operators.

The Court held that national legislation could not simply exclude such an operator from distribution-system-operator obligations where the system was being used to transport electricity to customers and no applicable exemption or derogation existed. EUR-Lex

Importance for LEMs

This is particularly significant.

A private or community-operated local network cannot necessarily avoid distribution regulation merely because it is small or serves a limited geographical area.

The legal classification of the network depends on its actual functions, not merely the label attached to it.

Case 4: Elektrorazpredelenie Yug

The CJEU's jurisprudence concerning the Bulgarian electricity-distribution system emphasises the importance of properly identifying what constitutes a distribution system under EU electricity law.

The Court's later ENGIE Deutschland judgment specifically noted that the concept of a distribution system already played a fundamental role under the earlier Electricity Directive. EUR-Lex

Relevance

This is important for:

• microgrids;
• private electricity networks;
• apartment-complex energy systems;
• industrial parks;
• community grids.

Case 5: Green Network SpA v Autorità per l'energia elettrica e il gas, C-66/13

This case concerned renewable electricity and national requirements concerning renewable-energy certificates.

Although it was not directly a P2P trading dispute, the judgment demonstrates how national renewable-electricity mechanisms interact with EU-level energy-market rules. EUR-Lex

Relevance

Local markets frequently involve renewable electricity. Therefore, questions of:

• renewable certificates;
• proof of renewable origin;
• cross-border electricity;
• market access

can become relevant to local trading systems.

16. Indian Case-Law and Regulatory Development

Indian electricity jurisprudence traditionally focuses more on:

• licensing;
• tariffs;
• regulatory jurisdiction;
• electricity trading;
• distribution;
• consumer rights;
• market structure.

The emerging P2P framework in Delhi is particularly significant because it directly addresses localised digital electricity transactions.

A recent 2026 APTEL judgment involving Indian Energy Exchange Ltd. v. CERC also illustrates the continuing legal development of India's organised electricity-market architecture. The case considered issues surrounding power exchanges, market coupling, the Electricity Act, 2003 and the Power Market Regulations, 2021. Indian Kanoon

The decision notes that Section 66 of the Electricity Act requires the Commission to endeavour to promote development of a market for power and that the regulatory framework governs transactions conducted through power exchanges. Indian Kanoon

Although a power-exchange dispute is different from a neighbourhood P2P market, the underlying principle is relevant: electricity markets operate within a statutory regulatory architecture rather than solely through private contractual arrangements.

17. Local Energy Market Governance Model

A comprehensive LEM framework can be represented as follows:

Prosumers
↓
Local Energy Platform
↓
Market Clearing / Price Discovery
↓
Metering & Verification
↓
Distribution System Operator
↓
Balancing & Settlement
↓
Consumer / Prosumer Accounts

Above this structure sits the electricity regulator, which supervises:

• licensing;
• tariffs;
• market conduct;
• consumer protection;
• network access;
• balancing;
• dispute resolution.

18. Key Legal Problems

1. Licensing uncertainty

Who legally sells the electricity—the prosumer, platform, aggregator or DISCOM?

2. Network-use charges

How should distribution costs be recovered?

3. Balancing

Who pays when local production differs from contracted production?

4. Market power

Could a dominant digital platform discriminate against participants?

5. Consumer protection

How are vulnerable consumers protected?

6. Data protection

Who controls smart-meter information?

7. Cybersecurity

Who bears responsibility for cyberattacks affecting transactions?

8. Grid security

Can economic transactions override technical grid constraints?

They cannot; physical system security must remain paramount.

19. Legal Principles Emerging from Case Law

Several principles can be identified from the European cases and emerging Indian regulatory practice.

Principle 1: Local markets remain regulated markets

Digital trading does not automatically remove electricity-sector regulation.

Principle 2: Physical networks remain legally significant

A local operator transporting electricity may attract distribution-system obligations, as demonstrated by ENGIE Deutschland. EUR-Lex

Principle 3: Market restrictions require justification

Bursa Română de Mărfuri and Hidroelectrica demonstrate the importance of competition and proportionality in electricity-market regulation. EUR-Lex

Principle 4: Energy communities require special regulatory treatment

EU law recognises their ability to participate in electricity markets while preserving consumer and system obligations. EUR-Lex

Principle 5: Technology cannot replace legal accountability

Blockchain, smart contracts and automated platforms must operate within licensing, network and consumer-protection requirements.

20. Future of Local Energy Markets

LEM development is likely to be closely connected with:

• rooftop solar;
• battery storage;
• electric vehicles;
• vehicle-to-grid systems;
• smart meters;
• artificial intelligence;
• demand response;
• virtual power plants;
• community microgrids;
• energy communities.

The future legal model is therefore likely to move from a simple generator–utility–consumer structure toward a multi-actor system involving prosumers, aggregators, communities, platforms and distribution-system operators.

In India, the Delhi P2P framework is an important early regulatory development because it demonstrates how local electricity trading can be introduced while retaining the DISCOM's role in physical electricity supply and billing/settlement. Derc

21. Conclusion

Local Energy Markets and Trading Systems represent a major transformation in electricity law. They enable consumers to become active market participants and allow distributed renewable generation, batteries and flexible demand to participate in electricity markets.

However, the central legal principle is that local trading does not mean deregulated trading. Electricity remains a network-dependent and highly regulated commodity. Consequently, an effective LEM framework must integrate:

1. market access;
2. licensing;
3. distribution-network regulation;
4. smart metering;
5. balancing responsibility;
6. network charges;
7. consumer protection;
8. data governance;
9. cybersecurity;
10. competition law; and
11. renewable-energy regulation.

The cases Bursa Română de Mărfuri, Hidroelectrica and ENGIE Deutschland demonstrate particularly important legal principles concerning electricity-market competition, proportionality, distribution-system regulation and market integration. EUR-Lex

For India, the Electricity Act, 2003, CERC's power-market framework and emerging state-level P2P regulations such as the DERC 2024 Guidelines provide the foundations from which a more comprehensive local-energy-market regime can develop. Derc
