1. Introduction

“Regulation embedded within regulation” refers to a regulatory structure in which one set of regulatory requirements is contained inside, dependent upon, or operationalised through another regulatory framework. In other words, regulation does not always operate as a single, independent rule. A primary regulation may establish a broad obligation, while a secondary regulation, licence condition, technical code, tariff order, standard, or administrative procedure determines how that obligation actually operates.

This concept is particularly important in energy law, where electricity, gas and renewable-energy activities are governed simultaneously by statutes, subordinate legislation, regulations, grid codes, licence conditions, tariff orders, environmental rules, procurement rules and contractual arrangements.

For example:

Electricity Act → Regulations → Grid Code → Licence Condition → Technical Operating Procedure

Here, each lower layer may contain regulatory requirements generated by the layer above it.

2. Meaning of Embedded Regulation

Traditional regulation can be represented as:

Legislature → Statute → Regulator → Rule → Regulated Entity

Embedded regulation is more complex:

Statute → Regulation → Sub-regulation/Code → Licence → Technical Standard → Operational Decision

The second regulatory layer does not necessarily operate independently. Its authority may derive from the first layer.

For example, a statute may require electricity utilities to maintain system reliability. A regulatory commission may then issue regulations prescribing reliability standards. A grid code may further specify frequency limits, reserve requirements and dispatch procedures.

Thus:

General regulatory obligation + specialised implementing regulation = embedded regulatory structure.

3. Main Characteristics

A. Hierarchical embedding

A lower-level regulatory instrument derives its authority from a higher-level instrument.

For example:

• Parliament establishes a statutory obligation.
• The regulator creates regulations under delegated authority.
• A grid code implements those regulations.
• A licence condition imposes the requirements on a particular utility.

The validity of the lower layer therefore depends partly upon the legal authority of the higher layer.

B. Functional embedding

Sometimes one regulation does not merely authorise another; it incorporates another regulatory regime into its own operation.

For example, an electricity licence may require the licensee to comply with:

• the Grid Code;
• environmental regulations;
• safety regulations;
• metering standards; and
• renewable-purchase obligations.

The licence therefore becomes a regulatory container incorporating multiple regulatory requirements.

C. Cross-referencing

Modern regulation frequently uses provisions such as:

“The licensee shall comply with the regulations specified by the Commission.”

or

“The generating station shall comply with the applicable Grid Code.”

This creates a legal relationship between two regulatory instruments.

D. Dynamic embedding

Embedded regulation can change over time without rewriting the parent statute.

A regulator may update technical standards, grid codes or procedures while the underlying statutory framework remains unchanged.

This is particularly significant in rapidly changing energy technologies such as:

• battery storage;
• smart grids;
• distributed generation;
• electric vehicles;
• artificial intelligence;
• demand response; and
• renewable-energy forecasting.

4. Embedded Regulation in Energy Law

Energy law provides an excellent illustration because electricity systems cannot be regulated through one statute alone.

A typical Indian electricity-regulation structure can be conceptualised as:

Electricity Act, 2003
↓
CERC/SERC Regulations
↓
Grid Code / Supply Code / Tariff Regulations
↓
Licence Conditions
↓
Operational Standards
↓
Actual conduct of utilities

The regulatory obligation therefore becomes increasingly specific as it moves downward.

For example, the Electricity Act establishes broad institutional and statutory duties, while regulations issued by the appropriate commission determine detailed matters such as tariff methodology, grid operation, transmission, open access and renewable-energy obligations.

5. Why Regulation Becomes Embedded

There are several reasons.

5.1 Technical complexity

Legislatures cannot realistically specify every technical requirement concerning electricity networks.

Consequently, legislation delegates technical rule-making to specialised regulators.

5.2 Need for flexibility

Energy technology changes much faster than primary legislation.

Embedded regulations allow regulators to modify technical requirements without repeatedly amending the parent statute.

5.3 Specialisation

Different regulatory layers can address different dimensions:

5.4 Coordination

Electricity regulation involves multiple institutions. Embedded rules allow different regulatory systems to interact.

6. Delegated Legislation and Embedded Regulation

The doctrine of delegated legislation is central to understanding embedded regulation.

A legislature may establish the framework while delegating limited rule-making authority to an administrative agency.

However, delegation cannot normally amount to an unrestricted transfer of legislative power.

Indian constitutional jurisprudence has repeatedly recognised this principle.

In re Delhi Laws Act, 1951

The Supreme Court considered the constitutional limits of legislative delegation.

The case established the importance of retaining essential legislative functions within the legislature while permitting delegation of subordinate matters.

This principle is directly relevant to embedded regulation because a subordinate regulatory instrument must remain within the authority granted by the parent legislation.

7. Case Law: Indian Examples

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

This is one of the most important cases for understanding regulatory hierarchy in Indian electricity law.

The Supreme Court examined the nature of regulations framed by CERC under the Electricity Act, 2003, particularly in the context of the regulatory framework governing electricity trading.

The Court recognised the significant statutory role of regulations made by the Commission.

Relevance to embedded regulation

The case demonstrates that:

Parliamentary statute → delegated regulations → regulated electricity activity

is not merely an administrative convenience. Regulations made under statutory authority can form a significant part of the legal architecture governing the electricity sector.

It also demonstrates why the legal source of a regulation matters: subordinate legislation must remain connected to the authority granted by the parent statute.

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

This case concerned power-purchase agreements, changes in circumstances and regulatory treatment of electricity generation.

The Supreme Court considered the interaction between:

• contractual arrangements;
• statutory electricity regulation;
• regulatory powers of CERC; and
• the contractual allocation of risks.

Importance

The case illustrates that electricity regulation does not operate in isolation from contracts.

A PPA may contain contractual obligations, while the electricity regulatory framework determines the legal and regulatory environment within which that contract operates.

This is a form of embedded regulation, because contractual rights and regulatory requirements can operate simultaneously.

7.3 Gujarat Urja Vikas Nigam Ltd. v. Essar Power Ltd., (2008) 4 SCC 755

The Supreme Court examined the regulatory powers of the State Electricity Regulatory Commission concerning disputes arising from electricity supply arrangements.

The case illustrates the broad regulatory environment created under the Electricity Act and the relationship between contractual arrangements and statutory regulatory authority.

Principle

A contractual relationship within the electricity sector may be subject to a statutory regulatory framework that exists above and around the contract.

Thus:

Contract → regulatory jurisdiction → statutory authority

may operate simultaneously.

7.4 U.P. Power Corporation Ltd. v. National Thermal Power Corporation Ltd., (2011) 12 SCC 400

The Supreme Court considered issues relating to electricity regulation, statutory powers and the regulatory framework established under the Electricity Act.

The case is useful for understanding how statutory regulatory institutions exercise powers within the larger legislative framework.

The broader lesson is that a regulator's authority is not self-created. It must be traceable to the statutory framework.

8. Administrative Law and Embedded Regulation

Embedded regulation raises important administrative-law questions.

Question 1: Who created the rule?

A rule may appear to be a technical standard, but if it creates legally binding obligations, its statutory source becomes important.

Question 2: Was there delegated authority?

The regulator must possess legal authority to make the subordinate rule.

Question 3: Is the subordinate rule consistent with the parent regulation?

A lower-level regulatory instrument cannot ordinarily contradict the higher-level legal framework from which its authority derives.

Question 4: Was procedural fairness followed?

Where regulations affect rights, interests or economic obligations, questions concerning consultation, procedure, transparency and natural justice may arise.

9. Case Law on Limits of Subordinate Regulation

State of Tamil Nadu v. P. Krishnamurthy, (2006) 4 SCC 517

The Supreme Court discussed the grounds upon which subordinate legislation may be challenged.

The Court recognised grounds including:

• lack of legislative competence;
• violation of fundamental rights;
• violation of constitutional provisions;
• failure to conform to the enabling statute; and
• manifest arbitrariness in appropriate circumstances.

Relevance

This case is particularly important to embedded regulation.

If Regulation B is embedded within Regulation A, Regulation B cannot simply assume unlimited authority.

Its legality can depend upon:

Parent Act → Parent Regulation → Subordinate Regulation

Each level must remain legally connected to the level above it.

10. Indian Constitutional Control

Embedded regulation remains subject to constitutional review.

The hierarchy can therefore be understood as:

Constitution
↓
Parliamentary/State legislation
↓
Delegated legislation
↓
Regulations
↓
Codes and standards
↓
Administrative decisions

The lower the regulatory instrument, the more important it becomes to identify its legal source and ensure consistency with superior law.

11. Embedded Regulation and the Electricity Grid

The electricity grid demonstrates the concept particularly clearly.

Suppose the primary legislation requires secure and reliable electricity supply.

The regulator may establish:

Reliability Regulation

That regulation may require compliance with:

Grid Code

The Grid Code may contain:

Frequency Standards

The system operator may then implement:

Dispatch Procedures

Thus a single statutory objective becomes progressively embedded into operational rules.

Example

Statutory duty: Maintain grid security
↓
Regulation: Establish reliability obligations
↓
Grid Code: Establish frequency and balancing requirements
↓
Operating procedure: Determine real-time response
↓
Control-room action: Dispatch or curtail generation

The final operational decision is therefore the endpoint of several layers of regulation.

12. Embedded Regulation and Tariff Regulation

Tariff regulation also illustrates this concept.

A statute may authorise an electricity commission to determine tariffs.

The commission may issue tariff regulations containing:

• cost components;
• depreciation methodology;
• return on equity;
• fuel-cost adjustment;
• performance standards;
• efficiency norms.

A tariff order then applies those regulations to a specific utility.

The structure becomes:

Statute → Tariff Regulation → Tariff Order → Consumer Bill

Here, the tariff order is effectively an application of embedded regulatory norms.

13. Embedded Regulation and Renewable Energy

Renewable-energy regulation increasingly involves several overlapping layers.

For example:

Electricity legislation
→ renewable-energy regulation
→ renewable purchase obligation
→ compliance mechanism
→ renewable-energy certificates
→ reporting and verification.

The legal obligation to procure renewable energy may therefore be implemented through another regulatory mechanism.

This creates an embedded structure in which the second layer makes the first layer operational.

14. Embedded Regulation and Environmental Law

Energy projects are also governed by environmental regulation.

A generating station may simultaneously be subject to:

• electricity legislation;
• environmental legislation;
• pollution-control requirements;
• land-use regulation;
• forest regulation;
• water regulation; and
• occupational safety requirements.

Consequently, obtaining an electricity licence does not necessarily eliminate obligations arising from other regulatory regimes.

This is better understood as regulatory layering rather than a single regulatory command.

15. Difference Between Embedded Regulation and Overlapping Regulation

These concepts should not be confused.

Overlapping regulation

Two independent regulatory regimes regulate the same activity.

Example:

Electricity regulation + environmental regulation

Embedded regulation

One regulatory requirement is incorporated into another regulatory instrument.

Example:

Licence condition → mandatory compliance with Grid Code

Therefore:

Overlap concerns multiple regulatory regimes operating alongside one another; embedding concerns one regulatory layer being incorporated into another.

16. Problems Created by Embedded Regulation

A. Regulatory complexity

Businesses may struggle to determine which requirement applies.

B. Hidden obligations

A licence may incorporate another document by reference, making the full regulatory burden difficult to identify.

C. Delegation concerns

A regulator may attempt to create obligations beyond the authority granted by the parent statute.

D. Accountability problems

When a technical standard causes legal consequences, it may become unclear whether responsibility lies with the legislature, regulator, system operator or licence authority.

E. Conflicting rules

Two embedded regulatory instruments may impose inconsistent requirements.

F. Excessive regulatory discretion

Highly technical regulations may provide regulators or system operators with significant discretion.

17. Judicial Review of Embedded Regulation

Courts can examine embedded regulatory structures through several doctrines:

17.1 Ultra vires

The subordinate rule must remain within the authority granted by the parent statute.

17.2 Legislative competence

The rule-making authority must possess constitutional competence.

17.3 Reasonableness

Regulatory requirements may be examined for legality and, where applicable, arbitrariness.

17.4 Procedural legality

Mandatory statutory procedures must be followed.

17.5 Natural justice

Where an administrative decision affects rights or interests, applicable procedural-fairness requirements may arise.

18. International Perspective

The same phenomenon exists outside India.

United Kingdom

Energy regulation involves interaction among:

• primary legislation;
• regulations;
• Ofgem regulatory decisions;
• licences;
• industry codes;
• network codes; and
• contractual arrangements.

European Union

EU energy governance demonstrates particularly complex embedded regulation because:

EU Treaty → Directive/Regulation → National legislation → National regulator → Network codes → Market rules

creates several regulatory levels.

United States

Energy regulation may similarly involve:

Federal statute → FERC regulations → regional transmission rules → tariffs → operating procedures.

The common principle is that modern infrastructure regulation is increasingly multi-layered.

19. Theoretical Significance

“Regulation embedded within regulation” reflects a transition from simple command-and-control regulation toward complex regulatory ecosystems.

Traditional model:

Government tells regulated entity what to do.

Embedded model:

Law establishes a regulatory framework → regulator creates rules → rules incorporate standards → standards govern operational systems → operational systems generate further compliance requirements.

The regulated entity therefore operates inside a nested regulatory environment.

This is especially important for:

• smart grids;
• AI-based energy management;
• automated electricity markets;
• distributed energy resources;
• energy-storage systems;
• digital metering;
• carbon markets; and
• cross-border electricity trading.

20. Conclusion

Regulation embedded within regulation describes a nested legal structure in which a regulatory instrument contains, incorporates, activates or depends upon another regulatory instrument.

In energy law, the structure may be represented as:

Statute → Regulations → Codes → Licence Conditions → Technical Standards → Operational Decisions

The concept is important because modern energy systems are too technically complex to be governed by primary legislation alone. Regulators therefore construct multiple layers of rules.

Indian cases such as PTC India Ltd. v. CERC, Energy Watchdog v. CERC, Gujarat Urja Vikas Nigam Ltd. v. Essar Power Ltd., In re Delhi Laws Act, and State of Tamil Nadu v. P. Krishnamurthy demonstrate important principles concerning delegated authority, regulatory powers, statutory interpretation, contractual interaction and judicial review of subordinate legislation.

The central legal principle is:

A regulation embedded within another regulation remains subordinate to the legal authority from which its regulatory power ultimately derives.

Thus, embedded regulation provides flexibility and technical precision, but it must remain subject to legality, statutory authority, constitutional limits, transparency and judicial review.
