1. Introduction

A Local Energy Market (LEM) is a decentralised electricity-market arrangement in which consumers, prosumers, distributed generators, batteries, electric vehicles, aggregators, and other local resources trade electricity or flexibility within a geographically or electrically defined area. Unlike the traditional electricity model—where generators sell into wholesale markets and distribution licensees supply consumers—an LEM can allow local bilateral trading, auctions, peer-to-peer (P2P) transactions, flexibility markets, or community energy sharing.

The legal importance of a local energy market therefore extends beyond determining who buys and sells electricity. A functioning LEM must answer a more difficult question: how are transactions measured, cleared, priced, billed, and financially settled while maintaining the physical security of the distribution network?

Recent European legal scholarship identifies the local market operator as potentially responsible for administering, clearing and settling local transactions, while also coordinating with distribution-system operators and wider wholesale or balancing markets. Taylor & Francis Online

Settlement structures are consequently the financial and legal backbone of a local energy market.

2. Meaning of Local Energy Market Settlement

Settlement refers to the process by which the financial consequences of electricity transactions are calculated and transferred between market participants after electricity has physically been generated, consumed, imported, exported, or curtailed.

A simplified settlement equation is:

Settlement Amount = Metered Energy × Applicable Settlement Price + Network Charges + Taxes/Levies ± Adjustments

For example, suppose a local solar prosumer exports 10 kWh and the agreed local market price is ₹7/kWh:

Energy payment = 10 × ₹7 = ₹70

But the final settlement may additionally include:

• distribution-network charges;
• balancing charges;
• platform/operator fees;
• renewable-energy charges;
• taxes;
• deviation charges;
• losses;
• ancillary-service payments; and
• adjustments resulting from meter corrections.

Thus, physical delivery and financial settlement are distinct legal concepts.

3. Main Components of a Local Energy Market Settlement Structure

A. Metering and Measurement

The first requirement is an accurate measurement of:

1. electricity generated;
2. electricity consumed;
3. electricity imported;
4. electricity exported;
5. battery charging/discharging;
6. demand response;
7. flexibility supplied; and
8. network losses where applicable.

Smart meters are particularly important because local markets may operate in short settlement intervals—for example, 15-minute or 5-minute intervals.

The legal framework should establish:

• who owns the meter;
• who can access meter data;
• the approved measurement standard;
• time synchronisation requirements;
• data retention;
• correction of erroneous readings; and
• procedures for disputes concerning meter accuracy.

Without reliable metering, a P2P or local-market settlement mechanism becomes legally vulnerable because the quantity forming the basis of payment cannot be independently verified.

B. Market Clearing

Before settlement, transactions must be cleared.

There are two principal structures.

1. Bilateral/P2P clearing

A consumer and prosumer agree directly:

Seller → Buyer

For example:

• Solar producer: 5 kWh
• Consumer: 5 kWh
• Contract price: ₹6/kWh

The platform records the transaction, while the distribution utility continues to physically deliver electricity through the network.

2. Centralised local-market clearing

Multiple buyers and sellers submit bids and offers to a local market operator.

For example:

The market operator determines the accepted transactions according to the applicable market-clearing rules.

This resembles conventional electricity-market clearing but at a smaller geographical or distribution-network level.

4. Settlement Price Structures

Several pricing models can be used.

A. Uniform Market-Clearing Price

All accepted transactions during a settlement interval receive one clearing price.

This provides simplicity and transparency.

For example:

Market-clearing price = ₹6/kWh

All accepted sellers receive ₹6/kWh, subject to applicable charges.

B. Pay-As-Bid Settlement

Each accepted seller receives its own accepted bid price.

For example:

• Seller A → ₹5/kWh
• Seller B → ₹5.50/kWh
• Seller C → ₹6/kWh

This structure is easier to understand contractually but can produce different revenues for similarly situated resources.

C. Locational Pricing

Local electricity markets may use prices reflecting the physical condition of the distribution network.

For example:

Area A has surplus solar → lower local price
Area B has congestion → higher local price

This creates a connection between market settlement and network constraints.

Such a model is legally significant because electricity cannot be treated as an ordinary commodity independent of network capacity.

5. Network Charges in Local Settlement

One of the most important issues is whether a local trade should pay the same network charges as electricity travelling through the wider transmission system.

A local transaction might involve:

Generator → Distribution Network → Local Consumer

Even if the buyer and seller are geographically close, the network is still being used.

The settlement system may therefore separate:

Energy price

Payment to the electricity seller.

Network-use charge

Payment for use of distribution infrastructure.

System-operation charge

Payment for balancing, scheduling, metering or system-operation services.

Market-platform charge

Payment to the entity operating the LEM.

This separation prevents the local energy price from being confused with the total electricity bill.

6. Loss Allocation

Electricity losses create a particularly difficult settlement problem.

Suppose:

• Generator injects: 100 kWh
• Consumer receives: 96 kWh
• Network losses: 4 kWh

The market must determine who bears the 4 kWh difference.

Possible approaches include:

1. seller bears losses;
2. buyer bears losses;
3. losses are allocated proportionally;
4. losses are incorporated into the market-clearing algorithm; or
5. distribution-system operator settles losses separately.

A legally robust system should specify this before transactions occur, rather than allowing the distribution utility to determine the allocation retrospectively.

7. Balancing and Imbalance Settlement

Local renewable generation is inherently uncertain.

A solar producer may contract to provide:

20 kWh

but actually produce:

17 kWh.

The resulting:

3 kWh shortfall

must be balanced by another resource.

The settlement framework therefore needs an imbalance price.

For example:

Contracted energy: 20 kWh
Actual energy: 17 kWh
Deviation: 3 kWh

The participant may have to pay:

3 kWh × imbalance price.

Conversely, a participant producing more than contracted may receive compensation, depending on the rules.

This makes settlement closely connected to grid balancing and system reliability.

8. Flexibility Settlement

Modern LEMs do not necessarily trade only electricity.

They may also trade:

• demand response;
• battery capacity;
• EV charging flexibility;
• load shifting;
• reactive power;
• congestion relief; and
• ancillary services.

The settlement structure must therefore distinguish between:

energy delivered and flexibility delivered.

For example, a battery may receive payment for being available to reduce local congestion even if it does not ultimately discharge.

9. Role of the Distribution System Operator

The Distribution System Operator (DSO) has a critical role because electricity trades occur on the distribution network.

The DSO may be responsible for:

• validating network capacity;
• providing connection data;
• identifying congestion;
• validating schedules;
• measuring network use;
• calculating losses;
• facilitating settlement;
• maintaining system security; and
• coordinating with the transmission/system operator.

However, the DSO's role must be carefully regulated to avoid conflicts of interest.

A DSO should not, for example, arbitrarily favour its own commercial interests over competing local-market participants.

10. Role of the Local Market Operator

A separate Local Market Operator (LMO) may administer:

1. registration;
2. bidding;
3. market clearing;
4. transaction matching;
5. settlement calculation;
6. payment reconciliation;
7. dispute resolution;
8. market monitoring; and
9. reporting.

Recent research specifically identifies administration, clearing and settlement as potential functions of an LMO and also highlights the need to coordinate local transactions with wholesale and balancing markets. Taylor & Francis Online

This creates an important institutional distinction:

DSO = physical network security

LMO = market administration

Supplier/aggregator = commercial relationship

Settlement agent = financial reconciliation

The same institution may perform several functions, but appropriate regulatory safeguards are necessary.

11. P2P Settlement

P2P electricity trading presents a particularly interesting legal model.

Under a P2P arrangement:

Prosumer A → Digital Platform → Consumer B

However, the electricity may still physically flow through the distribution network rather than directly from A's installation to B's premises.

Consequently, the legal system must distinguish:

Contractual electricity transaction

The financial agreement between A and B.

Physical electricity delivery

The actual movement of electricity through the network.

Network service

The distribution service enabling the transaction.

This distinction prevents the mistaken assumption that a digital P2P contract eliminates the regulatory role of the distribution licensee.

12. Indian Legal Position

India is particularly relevant because local energy settlement structures are developing within the framework of the Electricity Act, 2003, State Electricity Regulatory Commissions, distribution licensees, open-access rules, renewable-energy regulations and emerging P2P initiatives.

A significant recent development is the Delhi Electricity Regulatory Commission (DERC) framework concerning P2P green-energy transactions.

DERC has explained that P2P transactions involve electricity being traded between a prosumer and consumer through a digital platform, while continuing to operate within the existing electricity regulatory framework. It also states that the DERC P2P Guidelines require P2P transactions to be implemented through the distribution licensee's billing and settlement system, with electricity continuing to be supplied by the DISCOM. Derc

This is extremely important for settlement law.

It demonstrates a platform-plus-DISCOM settlement model, rather than completely independent electricity delivery.

Under such a model:

P2P transaction → platform → DISCOM billing/settlement → consumer/prosumer account

The regulatory authority therefore retains control over billing integrity, network operation and settlement.

13. Delhi P2P Regulatory Development

The DERC framework initially concerned P2P transactions between prosumers and consumers within the same distribution licensee.

DERC has subsequently considered questions involving transactions across different distribution-licensee areas and inter-State situations under the broader framework of the Electricity Act, tariff policy and relevant regulations. Derc

This illustrates an important principle:

Locality does not automatically remove electricity transactions from broader electricity-market regulation.

Once a transaction crosses:

• a distribution-licensee boundary;
• a State boundary;
• an open-access connection; or
• another regulated network,

additional settlement and scheduling rules may become applicable.

14. Maharashtra and Emerging P2P Regulation

P2P energy transactions are also being considered by Indian State regulators.

The Maharashtra Electricity Regulatory Commission's official hearing records show a 2025 petition seeking permission for P2P energy transactions through a technology-based P2P transaction platform under Section 86(1)(e) of the Electricity Act, 2003 and the State's rooftop renewable-energy regulations. Maharashtra Electricity Commission

This demonstrates that the legal architecture of local energy-market settlement in India is still developing through regulatory proceedings rather than being governed by one comprehensive national LEM statute.

15. Case Law: FERC v. Electric Power Supply Association

A highly relevant comparative authority is the United States Supreme Court decision:

Federal Energy Regulatory Commission v. Electric Power Supply Association, 577 U.S. 260 (2016).

The case concerned FERC's regulation of demand-response compensation in organised wholesale electricity markets.

The Supreme Court recognised FERC's authority to regulate wholesale-market compensation for demand response and upheld FERC's approach to compensating qualifying demand-response resources at the locational marginal price. SCOTUSblog

Relevance to local settlement

Although the case did not concern a neighbourhood LEM directly, it establishes an important legal principle:

Market settlement can legitimately compensate flexibility and demand reduction, not merely physical electricity generation.

This is highly relevant to future LEMs where batteries, EVs and flexible consumers participate in local congestion-management markets.

16. EnerNOC, Inc. v. EPSA

The EnerNOC litigation is particularly important because demand-response providers challenged restrictions on FERC's ability to establish compensation rules.

The Supreme Court ultimately recognised FERC's authority in the wholesale context and upheld the relevant compensation framework. SCOTUSblog

The broader significance for local markets is that market settlement rules can become a matter of regulatory jurisdiction, particularly where local resources affect regulated electricity markets.

17. FERC Order No. 745 as a Settlement Precedent

FERC Order No. 745 required qualifying demand-response resources participating in organised wholesale markets to receive the market price for energy when the applicable conditions were satisfied.

FERC explained that locational marginal pricing could appropriately reflect the marginal value of demand response when demand response is a cost-effective alternative to generation. Federal Energy Regulatory Commission

The principle is transferable to local-market design:

If a local resource provides a measurable system service, the settlement framework should identify the service and establish a transparent compensation methodology.

18. EnerNOC Settlement Enforcement Matter

FERC's enforcement record also demonstrates the importance of accurate settlement data.

In EnerNOC Inc. and Celerity Energy Partners LLC, 141 FERC ¶ 61,211 (2012), FERC approved a settlement involving inaccurate data submitted to ISO New England, resulting in overpayments for demand-response services, together with other compliance issues. Federal Energy Regulatory Commission

The matter illustrates why local-market settlement systems require:

• accurate meter data;
• auditable records;
• verification mechanisms;
• correction procedures;
• market surveillance; and
• penalties for inaccurate submissions.

Settlement is therefore not simply an accounting exercise—it is also a regulatory compliance mechanism.

19. European Legal Context

European Union electricity law provides an important conceptual foundation for local markets.

The EU's Clean Energy Package seeks to make electricity markets more consumer-centred and facilitates participation of consumers in renewable generation and flexibility markets. Taylor & Francis Online

However, P2P and local-market structures must coexist with established principles concerning:

• non-discriminatory market access;
• consumer protection;
• network access;
• balancing responsibility;
• supplier obligations;
• distribution-system operation; and
• electricity-market competition.

Legal scholarship has noted that P2P electricity trading may be possible under existing European electricity law but that the absence of specific provisions can create practical legal difficulties. Sage Journals

20. Settlement and Energy Communities

Energy communities can operate local markets by allowing members to:

• generate electricity;
• consume electricity;
• share renewable electricity;
• trade flexibility;
• operate batteries; and
• participate in local markets.

The settlement framework must determine whether transactions are treated as:

1. commercial electricity sales;
2. energy sharing;
3. internal community allocation;
4. peer-to-peer trading; or
5. market transactions.

This classification matters because different regulatory obligations can follow from each model.

21. Consumer Protection

Local settlement structures must protect consumers from:

• hidden fees;
• discriminatory pricing;
• inaccurate billing;
• automated trading errors;
• excessive imbalance charges;
• unclear contractual terms; and
• loss of access to regulated electricity supply.

A consumer participating in an LEM should receive a transparent statement showing, where applicable:

Energy purchased

• Network charge
• Market fee
• Taxes
  ± Adjustment
  = Final amount payable

This promotes procedural fairness and reduces billing disputes.

22. Dispute Resolution

A mature settlement framework should establish a hierarchy for disputes.

Stage 1 — Platform correction

The market operator checks transaction records.

Stage 2 — Meter verification

Meter data are examined.

Stage 3 — Settlement reconciliation

Financial records are recalculated.

Stage 4 — Regulatory complaint

The participant approaches the relevant electricity regulator or statutory grievance mechanism.

Stage 5 — Judicial review/arbitration

Where legally permitted, unresolved disputes can proceed to the appropriate adjudicatory forum.

This is especially important where automated digital platforms perform millions of settlement calculations.

23. Blockchain and Automated Settlement

Blockchain or distributed-ledger technology can potentially be used to record:

• P2P transactions;
• smart-meter readings;
• renewable-energy attributes;
• payment obligations; and
• settlement confirmations.

Smart contracts could theoretically execute:

Meter reading verified → transaction confirmed → payment automatically released.

However, technological automation does not eliminate legal responsibility.

Questions remain concerning:

• erroneous meter data;
• cyberattacks;
• smart-contract errors;
• consumer refunds;
• privacy;
• jurisdiction;
• liability; and
• regulatory supervision.

Therefore, code-based settlement should remain legally subordinate to the electricity regulatory framework.

24. Recommended Legal Architecture

A comprehensive local energy-market settlement framework should contain at least the following components:

25. Key Legal Principles

The settlement structure of a local energy market should be based on five fundamental principles.

1. Accuracy

Payments must correspond to verifiable electricity or flexibility delivered.

2. Transparency

Participants must understand how their settlement amount is calculated.

3. Non-discrimination

Comparable participants should not be arbitrarily treated differently.

4. Network neutrality

Local trading cannot compromise distribution-system security.

5. Regulatory accountability

Digital platforms and market operators must remain subject to electricity-law oversight.

26. Conclusion

Local Energy Market Settlement Structures provide the legal and financial mechanism through which decentralised electricity trading becomes operational. A local market cannot function merely by matching buyers and sellers; it requires a comprehensive settlement architecture connecting metering, market clearing, pricing, network charges, losses, balancing, billing and dispute resolution.

The emerging Indian P2P framework is particularly significant because the DERC model demonstrates that local digital trading can coexist with the traditional distribution-licensee system: the platform facilitates the transaction while the DISCOM remains involved in electricity supply and billing/settlement. Derc

Comparative authorities such as FERC v. EPSA and the EnerNOC proceedings further demonstrate that compensation for demand response, accurate market data and regulatory control over settlement are legally significant elements of modern electricity-market design. Federal Energy Regulatory Commission

Accordingly, the future legal model is likely to be hybrid rather than completely decentralised: local participants can trade electricity and flexibility through digital platforms, while the DSO, market operator and regulator continue to ensure network security, accurate settlement, consumer protection and compliance with wider electricity-market rules.
