1. Introduction

Public tendering is a central mechanism through which governments, public-sector undertakings, electricity utilities, regulators, and other public authorities procure goods, works, and services in the energy sector. It is particularly important for power generation, transmission, distribution, renewable-energy projects, fuel procurement, infrastructure construction, equipment supply, engineering-procurement-construction (EPC) contracts, and operation and maintenance services.

The fundamental objective of public tendering is to ensure that public resources are used through a process that is transparent, competitive, non-discriminatory, economical, and accountable. In India, public tendering is closely connected with constitutional principles under Articles 14 and 21, principles of administrative law, public-finance rules, sector-specific legislation, and judicial review.

Energy procurement presents special challenges because projects often involve very large investments, long-term contracts, technical qualifications, tariff implications, and public-interest considerations such as energy security and affordability.

2. Meaning of Public Tendering

A public tender is a formal procurement procedure in which a public authority invites eligible entities to submit bids for a specified requirement.

The normal process includes:

1. Identification of the energy-sector requirement.
2. Preparation of technical specifications.
3. Preparation of tender documents.
4. Publication of the tender notice.
5. Pre-bid consultations or clarification.
6. Submission of technical and financial bids.
7. Technical evaluation.
8. Financial evaluation.
9. Selection of the successful bidder.
10. Issue of letter of award.
11. Execution of the contract.
12. Performance monitoring and enforcement.

In competitive electricity procurement, the process may also involve tariff-based bidding, particularly for renewable-energy projects.

3. Legal Foundation in India

A. Article 14 of the Constitution

Article 14 requires the State to act fairly and not arbitrarily.

This is particularly significant in public tendering because a government authority cannot formulate tender conditions or evaluate bids in a manner designed to favour a particular bidder without a rational and lawful basis.

The Supreme Court has repeatedly held that State contracts cannot be awarded through arbitrary or discriminatory decision-making.

B. Article 19(1)(g)

Companies and individuals generally have a constitutional right to carry on lawful trade or business. Tender conditions can therefore affect market participation.

However, participation in a government tender is not an absolute fundamental right. The State can prescribe reasonable eligibility and technical requirements in the public interest.

C. Article 21

Where energy infrastructure directly affects essential services, public safety, health, and environmental interests, Article 21 can become relevant. Courts have increasingly considered environmental and public-interest dimensions of infrastructure decisions.

D. Public Trust and Public Interest

Energy resources and infrastructure frequently involve public assets, land, natural resources, and public money. Public authorities therefore have heightened obligations of transparency and accountability.

4. Major Principles Governing Public Tendering

4.1 Transparency

Tender conditions, eligibility requirements, evaluation methodology, timelines, and award decisions should be sufficiently clear.

Transparency reduces:

• favouritism;
• corruption;
• information asymmetry;
• arbitrary decision-making;
• manipulation of bid evaluation.

A tender authority should normally evaluate bids according to the criteria stated in the tender documents.

4.2 Equality and Non-Discrimination

A public authority cannot arbitrarily treat similarly situated bidders differently.

For example, if a renewable-energy tender specifies a particular technical qualification, the authority should not ordinarily waive that requirement for one bidder while enforcing it against another without a legally defensible reason.

4.3 Competitive Bidding

Competition helps the public authority obtain better value for money.

In electricity procurement, competition may help achieve:

• lower tariffs;
• efficient project development;
• better technology;
• improved contractual terms;
• efficient allocation of project risks.

However, competition must be balanced against legitimate technical and financial qualification requirements.

4.4 Reasonableness of Tender Conditions

Tender conditions cannot be completely unrestricted.

At the same time, courts recognise that the procuring authority usually possesses considerable expertise in determining:

• technical specifications;
• financial capacity;
• experience requirements;
• equipment standards;
• project timelines;
• performance guarantees.

Therefore, courts generally exercise restraint when reviewing technical tender conditions.

4.5 Level Playing Field

A public tender should provide bidders with a reasonably equal opportunity to compete.

A procuring authority should not substantially alter the competitive conditions after bids have been submitted in a manner that unfairly advantages a particular participant.

5. Tendering in the Electricity Sector

Public tendering has particular importance under India's electricity regulatory framework.

The Electricity Act, 2003 promotes competition and restructuring in the electricity sector. Competitive procurement is especially important for procurement of electricity by distribution licensees and for renewable-energy development.

For example, renewable-energy procurement may involve:

• solar power;
• wind power;
• hybrid renewable projects;
• firm and dispatchable renewable power;
• battery-storage projects;
• transmission-linked renewable projects.

Competitive bidding may determine the tariff at which electricity is supplied under a long-term Power Purchase Agreement (PPA).

6. Renewable-Energy Tendering

Renewable-energy procurement has become one of the most important applications of public tendering.

Government agencies and public-sector entities may conduct tenders for:

• solar PV projects;
• wind projects;
• solar-wind hybrid projects;
• renewable energy with storage;
• green hydrogen;
• green ammonia;
• battery energy storage systems;
• transmission infrastructure.

The tender may establish:

Bidder qualification → capacity allocation → tariff discovery → PPA → project implementation → commissioning.

Because renewable projects often receive policy support and involve long-term public or regulated procurement, transparent bidding is particularly important.

7. Tariff-Based Competitive Bidding

In electricity procurement, the successful bidder may be selected on the basis of the tariff offered.

For example:

Bidder A — ₹3.10/kWh
Bidder B — ₹3.25/kWh
Bidder C — ₹3.40/kWh

Subject to the tender's technical and commercial conditions, the lowest evaluated tariff may become relevant to selection.

However, L1 does not automatically mean that every tender must be awarded to the lowest numerical bid. The tender conditions, evaluation methodology, technical compliance, and applicable procurement rules determine how the successful bidder is selected.

8. Public Procurement and Judicial Review

One of the most important features of Indian tender law is that courts generally do not sit as appellate authorities over commercial decisions of government procurement agencies.

Judicial review normally focuses on questions such as:

• Was the decision arbitrary?
• Was there mala fide conduct?
• Was the decision discriminatory?
• Were the tender conditions manipulated?
• Was the authority acting outside its legal power?
• Was there a violation of natural justice where applicable?
• Was the decision irrational or perverse?
• Was the tender process fundamentally unfair?

Courts normally avoid replacing the procurement authority's technical or commercial judgment with their own.

9. Important Supreme Court Case Laws

9.1 Tata Cellular v. Union of India, (1994) 6 SCC 651

This is one of the leading Indian cases on judicial review of government contracts.

The Supreme Court recognised that government has considerable freedom in commercial matters but must comply with constitutional requirements of fairness, reasonableness, and non-arbitrariness.

The Court identified important grounds of judicial review, including:

• illegality;
• irrationality;
• procedural impropriety.

Importance for energy tendering

The principle applies directly to procurement by:

• electricity boards;
• public-sector energy companies;
• government departments;
• transmission utilities;
• distribution companies.

A court will generally examine the legality of the decision-making process rather than determine which commercial bid should have been accepted.

9.2 Ramana Dayaram Shetty v. International Airport Authority of India, (1979) 3 SCC 489

This case established a foundational principle that the State cannot distribute public benefits or contracts through arbitrary and discriminatory methods.

The Court emphasised that public authorities must act according to fair and transparent standards.

Energy-sector significance

The principle is applicable where a government energy agency:

• creates eligibility conditions;
• awards generation contracts;
• allocates public resources;
• selects EPC contractors;
• awards transmission or infrastructure contracts.

A public authority cannot formulate one standard and secretly apply another.

9.3 Reliance Energy Ltd. v. Maharashtra State Road Development Corporation Ltd., (2007) 8 SCC 1

The Supreme Court emphasised the concept of a level playing field in public contracting.

The Court connected competitive tendering with equality under Article 14.

Significance

In energy procurement, bidders should have a fair opportunity to compete. Tender conditions should not unnecessarily distort competition unless the restriction has a legitimate and rational basis.

9.4 Michigan Rubber (India) Ltd. v. State of Karnataka, (2012) 8 SCC 216

This is a leading authority concerning judicial review of tender conditions.

The Supreme Court stated that the tendering authority has substantial freedom in determining its requirements and conditions.

Interference is justified only where the action is:

• mala fide;
• arbitrary;
• discriminatory;
• unreasonable in the legal sense; or
• contrary to public interest.

Energy relevance

Energy projects frequently require specialised technical qualifications. Courts therefore generally allow procurement agencies considerable latitude in determining technical eligibility.

9.5 Jagdish Mandal v. State of Orissa, (2007) 14 SCC 517

The Supreme Court stressed judicial restraint in tender matters.

Courts should be cautious about interfering merely because another decision might appear commercially preferable.

Energy relevance

Suppose an electricity utility rejects one technical bid and accepts another. A court ordinarily will not substitute its own technical assessment unless the procurement decision suffers from a serious legal defect.

9.6 Afcons Infrastructure Ltd. v. Nagpur Metro Rail Corporation Ltd., (2016) 16 SCC 818

The Supreme Court reiterated that the author of a tender document is generally the best person to understand and interpret its requirements.

Courts should exercise restraint concerning interpretation of technical tender conditions.

Energy relevance

This is particularly important for:

• transmission projects;
• power plants;
• substations;
• grid projects;
• battery storage;
• renewable-energy infrastructure.

9.7 Silppi Constructions Contractors v. Union of India, (2020) 16 SCC 489

The Supreme Court reaffirmed the principle of judicial restraint in contractual and tender matters.

The Court recognised that procurement authorities often possess greater technical and commercial expertise than courts.

Importance

An unsuccessful bidder cannot normally obtain judicial intervention merely because it disagrees with the evaluation.

There must generally be a legally significant defect in the process.

10. Energy-Specific Judicial Considerations

Public tendering in the energy sector raises additional concerns beyond ordinary procurement.

A. Energy Security

The government may consider reliability and continuity of electricity supply.

B. Grid Stability

Technical requirements may be necessary to ensure that renewable or conventional generation does not undermine system stability.

C. Consumer Interest

Electricity procurement costs can ultimately affect consumer tariffs.

D. Environmental Protection

Tender specifications may incorporate environmental standards and emission requirements.

E. Domestic Manufacturing

Certain procurement policies may encourage domestic manufacturing, subject to applicable law and procurement rules.

F. Financial Viability

Energy projects frequently require long-term financing. Tender conditions may therefore require substantial net worth, experience, or financial capability.

11. Public Tendering and Power Purchase Agreements

A successful tender often results in a Power Purchase Agreement (PPA).

The PPA may address:

• tariff;
• capacity;
• commissioning;
• payment security;
• transmission;
• scheduling;
• force majeure;
• change in law;
• termination;
• default;
• dispute resolution.

The tender and subsequent PPA are therefore closely connected.

A dispute may arise when the winning bidder argues that the procuring entity subsequently changed the commercial assumptions on which the bid was based.

12. Role of Electricity Regulatory Commissions

Electricity regulators such as the Central Electricity Regulatory Commission (CERC) and State Electricity Regulatory Commissions can play important roles in matters concerning electricity procurement, tariffs, and regulatory approval.

Competitive procurement can intersect with regulatory functions concerning:

• tariff adoption;
• procurement costs;
• PPAs;
• transmission charges;
• renewable-energy obligations;
• market competition.

The precise regulatory role depends upon the statutory framework and nature of the transaction.

13. Public Tendering and Corruption Prevention

Because energy contracts can involve very large financial values, procurement systems must address corruption risks.

Important safeguards include:

• electronic tendering;
• published tender documents;
• predetermined evaluation criteria;
• conflict-of-interest rules;
• bid-security requirements;
• performance guarantees;
• audit trails;
• independent evaluation committees;
• disclosure requirements;
• grievance mechanisms.

A procurement process that lacks transparency can create both legal and financial risks.

14. Cancellation of Tenders

A procuring authority may sometimes cancel a tender.

For example:

• insufficient competition;
• defective tender specifications;
• change in project requirements;
• budgetary changes;
• regulatory changes;
• discovery of irregularities;
• significant changes in market conditions.

However, cancellation cannot ordinarily be used as a mechanism for arbitrary favouritism.

If the tender conditions reserve a right to cancel, that power must still be exercised consistently with constitutional and administrative-law principles.

15. Blacklisting and Debarment

Energy procuring authorities may seek to exclude contractors who have:

• committed fraud;
• submitted false documents;
• engaged in corrupt practices;
• seriously breached previous contracts;
• abandoned projects.

However, blacklisting has serious consequences.

The Supreme Court in Erusian Equipment & Chemicals Ltd. v. State of West Bengal, (1975) 1 SCC 70 recognised that blacklisting can have significant civil consequences and that procedural fairness is important.

Therefore, an energy-sector authority should ordinarily provide an affected contractor an appropriate opportunity to respond before imposing serious debarment, subject to the applicable procurement framework.

16. Public Interest versus Commercial Freedom

A recurring tension exists between two principles:

Government's commercial freedom
and
constitutional accountability.

Government agencies need flexibility because energy projects are technically complex and commercially sensitive.

But that flexibility cannot become unrestricted discretion.

The legal balance can be represented as:

Commercial discretion + transparency + equality + reasonableness + public interest = lawful public procurement

17. Challenges in Energy-Sector Tendering

Several problems can arise:

1. Bid manipulation

Tender conditions may allegedly be structured to favour particular participants.

2. Aggressive bidding

Bidders may quote extremely low prices and later face difficulty executing projects.

3. Project delays

Land, transmission connectivity, financing, and regulatory approvals may delay implementation.

4. Changing technology

Rapid technological development can make tender specifications outdated.

5. Tariff uncertainty

Changes in taxes, duties, financing costs, or equipment prices can affect project economics.

6. Litigation

Unsuccessful bidders may challenge the tender process, potentially delaying infrastructure development.

7. Limited competition

Highly restrictive qualification requirements can reduce the number of bidders.

18. Principles for Better Energy Tendering

An effective energy tender should generally incorporate:

1. Clear eligibility criteria
2. Objective evaluation methodology
3. Transparent technical specifications
4. Reasonable qualification requirements
5. Equal access to tender information
6. Electronic procurement
7. Adequate bid timelines
8. Transparent clarification procedures
9. Independent evaluation
10. Reasoned decision-making
11. Effective contractual safeguards
12. Appropriate dispute-resolution mechanisms

19. Conclusion

Public tendering is fundamental to the governance of the energy sector because energy infrastructure frequently involves public money, essential services, natural resources, regulated markets, and long-term contractual commitments.

Indian constitutional law does not prevent the government or public utilities from exercising commercial discretion. However, that discretion must operate within the requirements of Article 14, transparency, equality, fairness, reasonableness, and public interest.

The Supreme Court's decisions in Ramana Dayaram Shetty, Tata Cellular, Reliance Energy, Michigan Rubber, Jagdish Mandal, Afcons Infrastructure, and Silppi Constructions establish a consistent principle: courts should ensure legality and fairness in public procurement while exercising restraint over technical and commercial judgments of specialised authorities.

For the energy sector, the objective is therefore not merely to select the lowest bidder. A lawful tendering system must create a fair competitive process, protect public resources, maintain energy-system reliability, safeguard consumers, and ensure that the resulting project can actually be implemented.
