1. Introduction

Scale mismatch in electricity policy occurs when the geographical, institutional, temporal, or technological scale at which an electricity problem exists does not correspond to the scale at which regulation or policy is designed and implemented. Electricity systems operate simultaneously at several levels—household, distribution network, state/province, national grid, and regional or international interconnection. A policy designed at one level may therefore produce ineffective or unintended results when the underlying problem exists at another level.

For example, a national government may design a uniform electricity-market policy, while congestion actually occurs on a particular local transmission line. Conversely, a local distribution regulator may attempt to solve a problem—such as national power shortages—that requires coordinated national planning.

Scale mismatch is particularly important in modern electricity systems because decentralised renewable generation, distributed storage, electric vehicles, smart grids and cross-border electricity markets have made electricity governance increasingly multi-level.

2. Meaning of Scale Mismatch

Scale mismatch can arise in several forms:

A. Geographic scale mismatch

The policy jurisdiction may not correspond to the physical electricity network.

Electricity flows according to physical network conditions rather than administrative boundaries. A transmission constraint can therefore affect several jurisdictions even though regulatory authority is divided among them.

B. Temporal scale mismatch

Electricity markets operate in seconds, minutes and hours, whereas legislation and regulatory decisions may take months or years.

For instance, renewable generation can fluctuate rapidly because of weather, while infrastructure planning operates on a much longer cycle.

C. Institutional scale mismatch

Responsibilities may be divided among national governments, state governments, regulators, system operators and distribution companies.

If responsibilities overlap or leave gaps, policy implementation may become ineffective.

D. Technological scale mismatch

Traditional electricity regulation was largely designed around centralised generation and one-way electricity flows. Distributed generation and storage create a more complex system in which consumers may also become producers.

E. Market-scale mismatch

A market may be too small to manage a problem that has regional consequences, or too large to reflect local network constraints.

3. Why Scale Matters in Electricity Regulation

Electricity is different from many ordinary commodities because electricity must generally be balanced between generation and consumption in real time.

A power system can therefore be represented as:

Generation → Transmission → Distribution → Consumers

But modern systems increasingly involve:

Central generation + renewable generation + storage + prosumers + distributed energy resources + interconnected grids

A regulatory rule that considers only one portion of this system may create unintended consequences elsewhere.

For example, encouraging rooftop solar at the consumer level can reduce conventional electricity demand but may also create reverse power flows and distribution-network management problems.

Thus:

The scale at which a policy is made should correspond as closely as possible to the scale at which the regulated problem occurs.

4. Scale Mismatch and Electricity Federalism

Scale mismatch is particularly visible in federal systems.

In countries such as India, the United States, Australia and Canada, electricity responsibilities are distributed between different levels of government.

In India, electricity governance involves:

Union legislation and institutions;

State electricity regulators;

State governments;

Central Electricity Regulatory Commission (CERC);

State Electricity Regulatory Commissions (SERCs);

Central and State transmission utilities;

distribution companies;

system operators.

The Electricity Act 2003 provides an important institutional framework for dividing regulatory responsibilities.

The challenge is that electricity networks do not necessarily respect these jurisdictional boundaries.

5. Indian Legal Framework

The Electricity Act 2003 attempts to coordinate different regulatory scales.

Important provisions include:

Section 3

The Central Government is empowered to prepare the National Electricity Policy and National Electricity Plan.

This establishes a national planning scale.

Section 61

The Appropriate Commission must specify terms and conditions for tariff determination while being guided by several statutory principles.

Section 79

CERC has jurisdiction over specified interstate electricity matters, including interstate transmission.

Section 86

State Electricity Regulatory Commissions exercise important functions concerning intra-state electricity matters, including tariff regulation and renewable-energy promotion.

These provisions illustrate a basic principle of electricity governance:

interstate issues → central regulatory scale

intra-state issues → state regulatory scale

However, modern electricity markets frequently blur this distinction.

6. Case Law: PTC India Ltd. v. CERC

One of the most important Indian cases concerning electricity regulation is:

PTC India Ltd. v. Central Electricity Regulatory Commission, (2010) 4 SCC 603.

The Supreme Court considered the relationship between statutory regulations and electricity regulation under the Electricity Act.

The case is important for scale-mismatch analysis because it demonstrates that electricity regulation involves specialised statutory institutions operating within a structured national regulatory framework.

The Court recognised the importance of CERC's regulatory functions under the Electricity Act while also considering the relationship between regulations and statutory provisions.

Relevance

The case demonstrates that:

electricity regulation requires specialised institutions;

regulatory authority must remain within statutory boundaries;

different regulatory instruments operate at different institutional levels.

Thus, institutional scale cannot be separated from statutory allocation of power.

7. Case Law: Energy Watchdog v. CERC

Another major decision is:

Energy Watchdog v. Central Electricity Regulatory Commission, (2017) 14 SCC 80.

The Supreme Court considered disputes relating to power-purchase agreements and changes affecting electricity-generation costs.

The judgment is important because it illustrates the interaction between:

contractual arrangements;

regulatory intervention;

electricity-market conditions;

national energy policy.

The case demonstrates that electricity regulation often involves issues extending beyond the immediate contractual relationship between generator and purchaser.

Scale-mismatch significance

A generator may operate within one jurisdiction while its electricity is purchased or transmitted across state boundaries. Consequently, a purely local regulatory approach may not adequately address the economic and contractual realities of interstate electricity markets.

8. Case Law: Adani Power (Mundra) Ltd. v. Gujarat Electricity Regulatory Commission

The Supreme Court's decisions concerning Adani Power (Mundra) Ltd. illustrate another dimension of scale mismatch.

The disputes involved power-generation costs, fuel-price changes and power-purchase arrangements.

The cases demonstrate that electricity pricing can be influenced by factors operating at different geographical and economic scales.

For example:

local tariff regulation

may be affected by

national or international fuel-market conditions.

This creates a classic scale problem: the regulator may operate at a state level while important cost drivers originate outside the state.

9. Case Law: All India Power Engineers Federation v. Sasan Power Ltd.

The Supreme Court has repeatedly emphasised the statutory framework governing electricity procurement and regulation.

Cases concerning competitive bidding and power procurement demonstrate another scale problem.

Electricity procurement may be formally undertaken by a state distribution company, but the underlying generation market may involve:

national competition;

interstate transmission;

imported fuel;

long-term contracts;

central regulatory institutions.

Consequently, procurement decisions made at one scale can generate consequences at several other scales.

10. Scale Mismatch in Renewable Energy

Renewable energy provides one of the clearest examples.

Solar and wind resources are geographically uneven.

For example:

solar resources may be concentrated in particular regions;

wind resources may be concentrated in coastal or high-wind areas;

electricity demand may be concentrated elsewhere.

Therefore:

resource location ≠ generation location ≠ consumption location

This creates a scale mismatch.

A state may promote large-scale renewable generation, but transmission infrastructure may need to be developed at an interstate or national level.

11. Renewable Purchase Obligations

Renewable Purchase Obligations (RPOs) provide another example.

SERCs can establish renewable-energy obligations for obligated entities under the Electricity Act.

However, renewable-energy markets increasingly operate across state boundaries through:

renewable-energy certificates;

interstate transmission;

power exchanges;

green power markets.

Consequently, the environmental objective may be national while implementation may occur through state-level institutions.

This creates potential coordination problems.

12. Distributed Energy and Local Scale

Rooftop solar creates the opposite problem.

Traditional electricity regulation often assumed:

large generators → transmission → distribution → consumer

Distributed solar changes this into:

consumer ↔ distribution network

A household may simultaneously be:

electricity consumer;

electricity producer;

electricity exporter to the grid.

This creates regulatory questions concerning:

net metering;

electricity tariffs;

grid access;

technical standards;

compensation;

distribution-network costs.

These issues are highly local because distribution networks differ from one area to another.

A uniform national rule may therefore fail to reflect local network conditions.

13. Transmission Congestion

Transmission congestion is inherently network-wide.

Suppose:

Region A = renewable-energy surplus

and

Region B = electricity-demand surplus

A transmission corridor connecting them may become congested.

A state-level policy promoting additional generation in Region A may therefore create congestion in an interstate transmission system.

The problem is not simply:

“How much electricity should State A generate?”

It is:

“Can the wider network transport that electricity to where it is needed?”

This is a classic geographic scale mismatch.

14. Electricity Markets and Regional Integration

Regional electricity cooperation attempts to address scale mismatch by creating institutions at a scale corresponding to the electricity network.

A good example is the Southern African Power Pool (SAPP).

Electricity systems in Southern Africa are interconnected, meaning that electricity shortages, transmission constraints and generation surpluses can have cross-border effects.

Regional electricity cooperation therefore provides a governance mechanism that corresponds more closely to the physical scale of the interconnected system.

15. European Union Electricity Regulation

The European electricity market provides an important comparative example.

Electricity increasingly moves across national borders within the European internal energy market.

The European Union has therefore developed regional and EU-level institutions and rules addressing:

cross-border electricity trading;

transmission-system operation;

market coupling;

congestion management;

renewable-energy integration.

The legal system recognises that national electricity systems cannot always be regulated effectively as completely independent systems.

16. Case Law: PreussenElektra v Commission

The European Court of Justice's decision in:

PreussenElektra AG v Schleswag AG, Case C-379/98 (2001)

is significant in the development of European electricity-law principles.

The case concerned Germany's renewable-electricity support arrangements and their relationship with EU state-aid and internal-market principles.

The case demonstrates the tension between:

national energy policy;

environmental objectives;

electricity-market integration;

European-level competition rules.

This is an important example of vertical scale mismatch.

A national renewable-energy measure can have implications for a wider regional market.

17. Case Law: Essent Belgium

The Essent Belgium litigation before the Court of Justice also concerned renewable electricity and restrictions connected with electricity markets.

The broader significance is that environmental and energy policies adopted by individual Member States can affect cross-border electricity markets.

The European legal framework therefore attempts to balance:

national energy policy

with

regional electricity-market integration.

18. Scale Mismatch and Climate Policy

Electricity policy increasingly overlaps with climate policy.

Climate change is global, while electricity infrastructure is usually regulated nationally or locally.

This creates an enormous scale mismatch:

Global environmental problem → national/regional electricity regulation

For example, a country may introduce renewable-energy targets, but global emissions reductions depend on cumulative action across many jurisdictions.

Consequently, electricity regulation increasingly requires coordination between:

local governments;

national governments;

regional institutions;

international agreements.

19. Scale Mismatch and Energy Security

Energy security also illustrates the problem.

A distribution company may be responsible for maintaining local reliability.

But a major national electricity shortage can result from:

insufficient generation capacity;

fuel shortages;

transmission constraints;

extreme weather;

geopolitical disruption.

No single local regulator may possess sufficient authority to address all of these risks.

Effective energy security therefore requires multiple governance scales.

20. Temporal Scale Mismatch

Electricity policy also faces a temporal problem.

Infrastructure projects can require:

5–15 years

or longer to plan, approve and construct.

But electricity markets can change within:

days, hours or minutes.

For example, an unexpected increase in electricity demand may occur immediately, while construction of a new transmission line may take years.

Therefore, policymakers need both:

short-term operational mechanisms; and

long-term infrastructure planning.

21. Scale Mismatch and Regulatory Fragmentation

When several institutions regulate different parts of the electricity system, fragmentation can occur.

For example:

The challenge is ensuring that these levels operate coherently.

22. Consequences of Scale Mismatch

Scale mismatch can produce several consequences.

1. Regulatory gaps

No institution may have clear responsibility for a problem.

2. Overlapping authority

Multiple regulators may claim jurisdiction.

3. Delayed decision-making

Approval may have to pass through several institutional levels.

4. Inefficient investment

Infrastructure may be developed without considering wider network consequences.

5. Market distortion

Local policies can unintentionally affect regional markets.

6. Reliability problems

Failure to coordinate transmission and generation planning can threaten system reliability.

7. Unequal distribution of costs

One jurisdiction may obtain the economic benefits while another bears infrastructure or environmental costs.

23. Principle of Subsidiarity

One legal solution is the principle of subsidiarity.

Under this approach, decisions should be made at the lowest effective level of government.

For electricity:

household and local distribution matters may be addressed locally;

state-level matters may be handled by state regulators;

interstate transmission should be coordinated centrally;

cross-border electricity markets require regional cooperation.

The objective is not to centralise every decision but to match decision-making authority with the geographical and functional scale of the problem.

24. Polycentric Electricity Governance

Modern electricity regulation increasingly resembles polycentric governance.

Instead of one regulator controlling everything, multiple institutions exercise interconnected authority.

These may include:

governments;

electricity regulators;

transmission operators;

distribution companies;

market operators;

environmental authorities;

courts;

regional institutions.

The advantage is flexibility.

The risk is fragmentation.

Effective polycentric governance therefore requires:

clearly defined jurisdiction;

information sharing;

institutional coordination;

dispute-resolution mechanisms;

consistent technical standards.

25. Judicial Role in Resolving Scale Conflicts

Courts play an important role when different regulatory scales conflict.

Judicial review can determine:

whether a regulator exceeded its statutory jurisdiction;

whether central and state powers overlap;

whether regulatory decisions comply with statutory objectives;

whether contractual rights have been unlawfully affected;

whether electricity-market rules comply with constitutional or administrative-law principles.

Indian electricity jurisprudence demonstrates that courts generally work within the statutory allocation of regulatory powers rather than simply replacing specialised regulatory decisions with judicial policy preferences.

26. Conclusion

Scale mismatch in electricity policy arises when the scale of governance does not correspond to the scale of the electricity problem.

It may be:

geographical—local regulation versus interstate electricity flows;

institutional—overlapping regulatory authority;

temporal—rapid market changes versus slow infrastructure planning;

technological—centralised regulation versus distributed energy systems;

market-based—local policies affecting regional electricity markets.

Indian cases such as PTC India Ltd. v. CERC and Energy Watchdog v. CERC, together with European electricity-law cases such as PreussenElektra, demonstrate the importance of matching regulatory authority with the structure and consequences of electricity markets.

The central legal lesson is that effective electricity governance requires jurisdictional alignment. Regulation should be placed at the level capable of addressing the relevant problem, while mechanisms for coordination are necessary whenever electricity flows, markets, environmental effects or infrastructure consequences cross administrative boundaries.
