1. Introduction

Connection queue reforms refer to legal and regulatory changes designed to manage the large number of electricity-generation, storage, demand-response and other projects waiting to obtain grid connection. Traditional systems often operate on a “first-come, first-served” basis. However, rapidly increasing applications—particularly from renewable-energy and battery-storage projects—have created queues in which projects can remain for years without reaching construction or connection.

Reforms therefore seek to replace or modify traditional queue arrangements through mechanisms such as:

“first-ready, first-served” systems;

cluster studies;

financial deposits and readiness requirements;

withdrawal penalties;

milestones and deadlines;

automatic removal of inactive projects;

prioritisation of strategically important projects;

revised transmission-cost allocation;

queue-management or “use-it-or-lose-it” rules.

These reforms create significant legal challenges because they alter the relative position of projects that may already have spent substantial amounts of money and may have acquired an expectation of receiving grid access.

The central legal problem is therefore a balance between grid efficiency and reliability on one side, and fairness, legitimate expectations, property interests, non-discrimination and regulatory certainty on the other.

Recent litigation concerning the United States Federal Energy Regulatory Commission's Order No. 2023 provides an especially important illustration. In July 2026, the U.S. Court of Appeals for the D.C. Circuit upheld the principal challenged elements of that reform, including withdrawal penalties, study deadlines and energy-service modelling. (Justia Law)

2. Why Connection Queues Create Legal Problems

A connection queue determines who obtains access to scarce grid capacity and on what terms. Consequently, changing the queue is not merely an administrative exercise.

A developer entering a queue may have:

paid application and study fees;

purchased or leased land;

obtained environmental approvals;

signed power-purchase agreements;

secured financing;

ordered equipment;

incurred transmission-development costs; and

relied upon a particular regulatory framework.

When the regulator subsequently changes the queue rules, the developer may argue that the reform unfairly changes the legal conditions under which its investment was made.

The regulator, however, may respond that queue position cannot constitute an unconditional entitlement to grid connection, particularly where the network has limited physical capacity and connection depends upon technical studies.

This conflict produces several major legal questions.

3. Challenge Based on Retrospective Application

One of the most important challenges is whether new queue rules can legally apply to projects that entered the queue under the previous regime.

Example

Suppose:

Project A entered the queue in 2022.

Project B entered in 2025.

The original rules used first-come, first-served.

In 2026, the regulator introduces a first-ready, first-served system.

Project A may argue that it acquired a valuable procedural position when it entered the queue.

The regulator may argue that no final right to connection existed until technical and regulatory conditions were satisfied.

Legal issue

Courts may therefore need to determine whether:

a queue position constitutes a vested legal right or merely a procedural opportunity subject to continuing regulation.

The distinction is particularly important because electricity systems are heavily regulated and connection depends upon system security.

4. Legitimate Expectation

Connection queue reforms can also trigger the doctrine of legitimate expectation.

A developer may claim that representations made by a regulator or transmission operator created an expectation that:

its application would be processed in a particular order;

certain study procedures would apply;

connection costs would be calculated according to existing rules;

its queue position would be preserved.

However, legitimate expectation generally does not mean that a regulatory regime can never be changed.

The legal question is whether the expectation was sufficiently clear and reasonable and whether overriding public-interest considerations justify the regulatory change.

This is particularly significant in electricity markets because grid operators must continuously respond to:

new generation technologies;

changing electricity demand;

network congestion;

reliability concerns;

climate policy;

cybersecurity;

storage deployment; and

changing transmission requirements.

5. Equality and Non-Discrimination

Queue reforms can be challenged if they give preferential treatment to particular categories of projects.

For example, a reform might prioritise:

projects with secured financing;

renewable-energy projects;

projects located in designated energy zones;

projects serving strategic demand;

storage projects;

projects that can connect quickly.

The legal challenge is whether such distinctions have an objective and rational basis.

Indian position

This issue is particularly relevant under Article 14 of the Constitution of India, which prohibits arbitrary discrimination.

A recent Karnataka High Court decision involving Central Transmission Utility of India Ltd. v. Rays Power Infra Ltd. concerned the interaction between renewable-energy-park authorisation and queue-based connectivity under the General Network Access framework. The court considered whether special treatment for renewable-power-park developers was constitutionally permissible. It concluded that the classification was based on an intelligible differentia and had a rational connection with the regulatory objective of orderly transmission development and avoiding speculative blocking of transmission capacity. (Indian Kanoon)

The case demonstrates an important principle:

Different treatment of applicants is not necessarily unlawful discrimination if the regulatory classification has a legitimate objective and rational relationship to that objective.

6. Property and Investment Rights

Developers may also argue that removal from a queue or substantial alteration of connection conditions interferes with their economic interests.

Possible claims include:

deprivation of property;

interference with contractual rights;

regulatory taking;

destruction of investment-backed expectations;

compensation claims.

These arguments are particularly significant where developers have incurred millions of dollars or substantial infrastructure costs.

However, obtaining a queue position ordinarily does not mean that the developer owns a specific portion of transmission capacity.

The legal character of the interest therefore becomes critical:

Application → Queue Position → Study → Conditional Connection → Interconnection Agreement → Actual Connection

The stronger the developer's legal rights have become along this chain, the stronger the argument may be that regulatory alteration requires procedural or substantive protection.

7. Withdrawal Penalties

A major reform mechanism is the introduction of financial penalties for withdrawal.

The objective is straightforward: speculative applications can occupy valuable queue capacity and force transmission operators to repeatedly perform studies.

FERC Order No. 2023 provides a prominent example. It replaced the traditional serial approach with a first-ready, first-served clustered process, introduced substantial deposits, and established withdrawal penalties that increase as a project progresses through the interconnection process. (Justia Law)

Developers challenged these penalties on several grounds, including:

lack of statutory authority;

excessive financial burden;

due process;

arbitrary treatment;

uncertainty in network-cost estimates.

The D.C. Circuit rejected those challenges in Advanced Energy United v. FERC (2026) and held that FERC acted within its statutory authority and reasonably explained the reform. (Justia Law)

This is an important precedent because it demonstrates judicial acceptance of the proposition that queue discipline can legitimately be enforced through financial incentives and penalties, provided the regulator has statutory authority and provides a reasoned explanation.

8. Study Deadlines and Regulatory Accountability

Another major challenge concerns imposing deadlines on transmission operators.

Traditional rules sometimes required transmission providers to make “reasonable efforts” to complete studies within specified periods.

Queue reform can instead impose:

mandatory deadlines;

automatic financial penalties;

compensation for delays;

reporting requirements;

regulatory enforcement.

FERC Order No. 2023 replaced the previous reasonable-efforts approach with firm study deadlines and late fees for certain delays. (Justia Law)

Transmission providers argued that such penalties could exceed regulatory authority and unfairly penalise operators for circumstances outside their control.

The D.C. Circuit nevertheless upheld the challenged framework, finding that FERC had adequately justified its approach. (Justia Law)

The broader legal principle is that regulators may impose performance obligations on network operators where delay has systemic consequences, but the regulatory framework should contain appropriate safeguards for circumstances genuinely beyond the operator's control.

9. Due Process and Procedural Fairness

Queue reform can affect projects economically even where the reform does not formally cancel their licences.

Developers may therefore challenge:

inadequate notice;

insufficient consultation;

absence of an opportunity to object;

automatic removal;

automatic penalties;

failure to provide appeal mechanisms.

Procedural fairness becomes particularly important where a project is removed because it allegedly failed to satisfy a milestone.

A legally robust system should therefore establish:

clear milestones;

objective evidence requirements;

notice of non-compliance;

reasonable opportunity to cure;

extension procedures;

force-majeure protections;

review or appeal mechanisms.

FERC's Order 2023 framework illustrates this approach by incorporating limited opportunities for penalty-free withdrawal and an appeals mechanism concerning certain late fees. (Justia Law)

10. Regulatory Authority and Ultra Vires Challenges

A regulator cannot reform a connection queue merely because the reform appears desirable.

It must possess statutory authority.

Consequently, a transmission operator or developer may argue that the regulator has:

exceeded its statutory jurisdiction;

imposed penalties not authorised by legislation;

changed contractual rights without legislative authority;

regulated matters reserved to another regulator;

interfered with state or local jurisdiction.

This issue was central to litigation surrounding FERC Order 2023.

The D.C. Circuit examined whether FERC possessed authority under the Federal Power Act to reform interconnection procedures. The court upheld FERC's authority, concluding that interconnection practices affecting wholesale electricity markets fell within its statutory regulatory responsibilities. (Justia Law)

11. Cost Allocation as a Legal Challenge

Connection reforms often change who pays for network upgrades.

Possible models include:

shallow connection charging;

deep connection charging;

participant-funded upgrades;

socialised transmission costs;

proportional allocation among cluster participants;

beneficiary-pays principles.

A developer may challenge a cost allocation method as:

discriminatory;

arbitrary;

economically unreasonable;

inconsistent with the applicable statute;

incompatible with previously agreed contractual arrangements.

Cost allocation is particularly difficult because an individual project may trigger network reinforcement that also benefits future projects.

Thus, queue reform must address the difficult question:

Should the first project pay for an upgrade that ultimately benefits many future users?

12. The “First-Ready, First-Served” Model

The movement from first-come, first-served to first-ready, first-served represents one of the most significant developments in queue regulation.

Under first-come, first-served:

earlier application = earlier queue position.

Under first-ready, first-served:

demonstrated project maturity = stronger priority.

The advantage of the latter approach is that speculative projects are less capable of occupying scarce capacity.

But it generates legal questions concerning:

how “readiness” is defined;

whether readiness requirements are objective;

whether small developers can satisfy them;

whether financial requirements discriminate against less-capitalised developers;

whether existing projects should be grandfathered.

The European Commission has similarly identified speculative applications and sequential first-come, first-served systems as significant contributors to grid-connection queues. EU guidance emphasises that connection refusal must be based on objective and technically/economically justified criteria, while EU electricity law does not itself mandate a first-come, first-served system. (EUR-Lex)

13. Indian Legal Context

India's electricity sector is increasingly confronting queue-management problems as renewable generation expands and transmission connectivity becomes more valuable.

The legal framework involves institutions such as:

Central Electricity Regulatory Commission (CERC);

Central Transmission Utility of India Ltd. (CTUIL);

State Electricity Regulatory Commissions;

State Transmission Utilities;

Grid-India;

generating companies and renewable-energy developers.

The Electricity Act, 2003, CERC regulations and General Network Access framework provide the principal legal architecture.

A particularly important concern is the prevention of speculative reservation of transmission capacity.

The Indian government reported in December 2025 that CTUIL had revoked connectivity for 24 grantees representing 6,343 MW since 2022 because of developer delays, while multiple petitions challenging or seeking protection from revocation remained pending before CERC. (Press Information Bureau)

This demonstrates the practical tension between:

efficient use of scarce transmission capacity

and

protection of developers who argue that delay or non-compliance should not automatically result in loss of connectivity.

14. Relevant Indian Case Law

A. Reliance Energy Ltd. v. Maharashtra State Road Development Corporation Ltd. (2007)

This Supreme Court decision is relevant to the broader principle of fairness and a level playing field in regulated infrastructure decision-making.

The case has been relied upon in later electricity-connectivity litigation concerning situations where administrative uncertainty could affect applicants' ability to obtain access before available capacity is exhausted. (Indian Kanoon)

Its relevance to queue reforms lies in the principle that administrative and regulatory systems should not create arbitrary barriers that effectively prevent similarly situated participants from competing for access.

B. Power Grid Corporation of India Ltd. v. Green Infra Renewable Energy Ltd. (CERC, 2017)

In this proceeding, Power Grid sought regulatory intervention concerning underutilisation of bays associated with connectivity granted to wind and solar projects. CERC considered the problem under its statutory and regulatory powers, including provisions concerning removal of difficulties and inherent regulatory powers. (CaseMine)

The case is particularly useful for understanding the legal basis for intervention where connectivity has been granted but infrastructure remains underutilised.

It illustrates an important regulatory principle:

Granting connectivity without ensuring timely utilisation can itself create systemic problems for the transmission network.

C. Central Transmission Utility of India Ltd. v. Rays Power Infra Ltd. (Karnataka High Court, 2026)

This case is directly relevant to queue-based connectivity.

The litigation involved renewable-power-park developers and questions concerning reservation and grant of connectivity under the GNA framework. The court considered arguments that preferential treatment could disturb the statutory queue and affect other applicants.

The court nevertheless upheld the regulatory distinction, finding that the requirement of government authorisation for renewable-power-park treatment had a rational relationship with orderly development of the national transmission network and prevention of speculative blocking of transmission capacity. (Indian Kanoon)

The case demonstrates that queue priority may legally be differentiated where the distinction is supported by the statutory scheme and a rational regulatory objective.

15. European Union Perspective

EU electricity law provides another important perspective.

The European Commission has identified:

speculative connection requests;

projects that fail to mature;

inadequate administrative capacity;

sequential first-come, first-served processing;

as factors contributing to connection queues. (EUR-Lex)

The EU framework emphasises non-discriminatory third-party access and requires that refusal of network access be supported by objective and technically/economically justified grounds.

The 2024 electricity-market reforms also introduced measures addressing growing grid-connection queues. (EUR-Lex)

The European approach therefore illustrates that queue reform does not necessarily conflict with open network access. Instead, the central legal requirement is that prioritisation and rejection mechanisms be transparent, objective and non-discriminatory.

16. Constitutional and Administrative-Law Dimensions

Connection queue reforms can be challenged through several administrative-law doctrines.

16.1 Arbitrariness

A reform may be challenged if the regulator cannot demonstrate a rational connection between:

the problem identified → the regulatory solution adopted.

16.2 Legitimate expectation

Existing applicants may argue that they reasonably relied upon the previous queue structure.

16.3 Proportionality

A court may examine whether the regulatory burden imposed on developers is proportionate to the objective of eliminating speculative applications.

16.4 Equality

Different treatment of project categories must have a rational basis.

16.5 Natural justice

Applicants facing removal or penalties may require notice and an opportunity to respond.

16.6 Judicial review

Courts generally do not substitute their technical judgment for that of electricity regulators. Instead, judicial review commonly focuses on:

statutory authority;

procedural legality;

rationality;

evidence;

discrimination;

reasoned decision-making.

The 2026 D.C. Circuit decision concerning FERC Order 2023 is a useful example: the court examined whether the Commission had acted within its authority and adequately explained its regulatory choices, ultimately upholding the challenged provisions. (Justia Law)

17. Major Legal Challenges Summarised

18. Key Legal Principles Emerging

Several principles can be extracted from the developing jurisprudence.

First

A queue position is not necessarily an unconditional right to grid connection.

Connection remains subject to technical, regulatory and system-security requirements.

Second

Regulators possess significant authority to reform dysfunctional queue systems, particularly where congestion and speculative applications undermine the electricity market.

The 2026 D.C. Circuit decision concerning FERC Order 2023 strongly supports this proposition. (Justia Law)

Third

Queue reform must be objectively structured.

Readiness requirements, deposits, penalties and cancellation mechanisms should be based on transparent criteria.

Fourth

Existing applicants require particular attention.

Even where reforms are legally permissible, transitional provisions may be necessary to reduce disputes involving investments made under the previous regulatory framework.

Fifth

Non-discrimination does not necessarily mean identical treatment.

Different treatment can be lawful where it is supported by the statutory framework and a rational regulatory objective, as illustrated by the Rays Power litigation. (Indian Kanoon)

19. Conclusion

Legal challenges to connection queue reforms arise because grid capacity is a scarce and regulated public infrastructure resource, while electricity developers require predictable access to that infrastructure to make long-term investments.

The fundamental legal tension is between:

regulatory flexibility necessary to manage an evolving electricity system

and

legal certainty necessary to protect investors and maintain fairness among competing applicants.

Modern queue reforms increasingly favour project readiness, financial commitment, milestone compliance and efficient use of network capacity over simple chronological priority. FERC Order 2023 represents a major example, replacing serial processing with clustered, first-ready, first-served procedures and introducing deposits, withdrawal penalties and study deadlines. The D.C. Circuit's July 2026 decision upheld the principal challenged features of that framework. (Justia Law)

In India, the same legal problem is emerging through GNA connectivity, renewable-energy-park reservations, revocation of connectivity and disputes concerning the use of transmission capacity. Indian decisions demonstrate that regulators and courts are increasingly concerned with preventing speculative blocking of scarce transmission capacity, while still preserving equality, procedural fairness and the statutory rights of competing developers. (Indian Kanoon)

Thus, legally sustainable connection queue reform requires a combination of clear statutory authority, transparent priority criteria, non-discrimination, procedural safeguards, proportionate penalties, transitional arrangements and effective review mechanisms. These elements allow regulators to address queue congestion without unnecessarily undermining legitimate investment expectations or the rule of law.
