1. Introduction

Municipal Renewable Energy Procurement refers to the legal, regulatory and administrative process through which a municipality, municipal corporation, urban local body or municipal electricity utility obtains electricity from renewable sources such as solar, wind, small hydro, biomass and waste-to-energy for municipal buildings, street lighting, water and sewage systems, public transport infrastructure and other civic services.

In India, municipal procurement sits at the intersection of municipal law, the Electricity Act, 2003, electricity-regulatory law, public procurement law, environmental law and renewable-energy policy. The municipality may procure renewable electricity directly for its own consumption, through a distribution licensee, through competitive bidding, through open access, through renewable-energy certificates, or through arrangements involving municipal waste-to-energy projects.

The issue has become particularly significant because renewable procurement is no longer merely an environmental policy choice. Renewable Purchase Obligations (RPOs), competitive procurement mechanisms and regulatory requirements can create legally enforceable obligations for electricity-sector entities.

2. Meaning of Municipal Renewable Energy Procurement

Municipal renewable procurement can take several forms:

Direct purchase of renewable electricity from a generator.

Long-term Power Purchase Agreements (PPAs) for solar, wind or other renewable projects.

Competitive bidding for renewable electricity.

Open-access procurement from renewable generators.

Municipal rooftop solar and net-metering arrangements.

Municipal waste-to-energy procurement, particularly where municipal solid waste is used as fuel.

Renewable Energy Certificate (REC) procurement for satisfying applicable renewable obligations.

Green power procurement through distribution licensees or other authorised mechanisms.

The legal structure depends on whether the municipality is merely a consumer of electricity, a distribution licensee, an obligated entity, or an entity developing and procuring power from a municipal renewable-energy project.

3. Statutory Framework

A. Electricity Act, 2003

The principal legislation is the Electricity Act, 2003.

Section 86(1)(e) empowers State Electricity Regulatory Commissions to specify, for distribution licensees, a minimum percentage of electricity consumption to be procured from renewable sources, taking account of resource availability and tariff impact.

Therefore, the municipal dimension becomes especially important where a municipal electricity undertaking itself functions as, or is treated as, a distribution licensee.

Section 63 is also important because electricity procurement through competitive bidding can involve tariff adoption by the appropriate regulatory commission.

4. Municipalities as Electricity Consumers

A municipality normally purchases electricity for:

street lighting;

municipal offices;

schools and hospitals;

water-supply pumping;

sewage-treatment plants;

solid-waste facilities;

public transport;

parks and public facilities;

emergency infrastructure.

The municipality can therefore become a substantial electricity consumer.

Renewable procurement may reduce dependence on conventional electricity and can be integrated into municipal climate and sustainability planning.

However, the municipality must distinguish between:

municipal procurement authority and electricity-sector regulatory authority.

A municipality cannot simply bypass the Electricity Act or State electricity regulations merely because the procurement is connected with a municipal project.

5. Municipalities as Distribution Licensees

The legal position becomes more significant where a municipal undertaking actually distributes electricity.

A leading example is Brihanmumbai Electric Supply & Transport Undertaking (BEST). The Appellate Tribunal dealt with BEST's status as a municipal corporation/local authority and electricity distribution utility and considered its renewable purchase obligations under the Maharashtra regulatory framework. (Indian Kanoon)

The case demonstrates an important principle:

Municipal status does not automatically remove an electricity-distribution undertaking from the regulatory framework applicable to distribution licensees.

Consequently, where a municipal electricity undertaking is legally responsible for electricity distribution, renewable procurement can become part of its statutory regulatory obligations.

6. Renewable Purchase Obligation

RPO is one of the central mechanisms connecting renewable energy with electricity procurement.

An RPO generally requires an obligated entity to procure a specified quantity or percentage of electricity from renewable sources.

The Supreme Court's decision in Gujarat Urja Vikas Nigam Ltd. v. Renew Wind Energy (Rajkot) Pvt. Ltd. (2023) is important in understanding the legal framework surrounding renewable procurement. The case concerned Gujarat's renewable-source regulations, under which distribution licensees, captive users and open-access consumers were required to meet specified renewable procurement requirements. (Sci API)

The case illustrates that renewable procurement requirements are capable of being implemented through electricity regulations made under statutory authority.

7. Municipal Waste-to-Energy Procurement

Municipalities have a particularly important role in waste-to-energy.

Municipal solid waste can be processed through technologies such as:

incineration;

biomethanation;

refuse-derived fuel;

landfill-gas recovery; and

other waste-processing technologies.

The resulting electricity may qualify within applicable renewable-energy frameworks.

A significant recent case is Municipal Corporation of Delhi v. Gagan Narang (2025).

The dispute concerned the Municipal Corporation of Delhi's proposed waste-to-energy project at Narela-Bawana. MCD had undertaken a tariff-based bidding process and contemplated allocation of the resulting electricity among Delhi distribution licensees in accordance with their renewable purchase obligations. (Indian Kanoon)

The Supreme Court's consideration of the matter demonstrates that municipal authorities can have an important role in structuring procurement of electricity from municipal waste-to-energy facilities, while remaining subject to the statutory electricity-regulatory framework.

This is particularly relevant because waste-to-energy procurement simultaneously involves:

municipal solid-waste law + environmental regulation + electricity regulation + public procurement + tariff regulation.

8. Competitive Bidding

Municipal renewable procurement should ordinarily be structured through a transparent procurement mechanism.

Competitive bidding may involve:

preparation of technical specifications;

determination of renewable-energy capacity;

preparation of tender/RFP documents;

qualification of bidders;

technical evaluation;

financial bidding;

selection of successful bidder;

tariff adoption or regulatory approval where required;

execution of PPA;

project construction;

commissioning;

scheduling and settlement of electricity.

The Central Electricity Regulatory Commission maintains competitive-bidding guidelines covering several renewable procurement models, including solar PV, wind, wind-solar hybrid, renewable-plus-storage and firm/dispatchable renewable power. (CERC)

For municipal procurement, the tender must also comply with applicable municipal procurement rules and financial-control requirements.

9. Power Purchase Agreements

The PPA is the principal contractual instrument governing renewable procurement.

Important clauses generally include:

contracted capacity;

tariff;

tariff escalation;

commissioning date;

generation obligations;

scheduling;

forecasting;

transmission arrangements;

grid connectivity;

payment security;

change in law;

force majeure;

curtailment;

renewable-energy attributes;

REC ownership;

environmental attributes;

default;

termination;

dispute resolution.

A municipality should clearly determine who owns the renewable attributes associated with the electricity.

Otherwise, disputes can arise over whether the municipality or generator can claim the renewable electricity for compliance purposes.

10. Renewable Energy Certificates

RECs provide another mechanism for satisfying renewable procurement requirements.

Under the CERC REC framework, one certificate generally represents 1 MWh of renewable electricity generated and injected, or deemed injected in specified circumstances, into the grid. The framework also provides technology-specific certificate multipliers. (CERC)

For municipalities, RECs can be relevant where:

physical renewable procurement is insufficient;

the municipality qualifies as an obligated entity;

applicable regulations permit REC-based compliance; or

municipal electricity consumption is being matched with renewable attributes.

However, REC procurement should not be confused with physical delivery of renewable electricity.

11. Open Access and Municipal Renewable Procurement

Large municipal consumers may consider renewable electricity through open access.

This may allow electricity to be procured from renewable generators located outside the municipality, subject to:

eligibility requirements;

open-access regulations;

transmission/distribution charges;

wheeling charges;

cross-subsidy surcharge where applicable;

additional surcharge where applicable;

banking rules;

scheduling and deviation settlement requirements.

Therefore, a municipality considering open-access renewable procurement must conduct both legal and economic due diligence.

12. Municipal Rooftop Solar

Rooftop solar is another important procurement mechanism.

Municipal authorities can install solar systems on:

administrative buildings;

schools;

hospitals;

water-treatment plants;

parking facilities;

bus depots;

sewage-treatment facilities;

markets.

The municipality may use:

CAPEX model

The municipality purchases and owns the solar system.

RESCO model

A private developer installs and operates the system and sells electricity to the municipality under a long-term arrangement.

Hybrid model

The municipality and private developer share investment, ownership or savings.

The legal structure must address procurement rules, property rights, grid connection and applicable electricity regulations.

13. Renewable Procurement and Public Procurement Law

Because municipal funds are public funds, procurement must satisfy principles of:

transparency;

equality;

non-arbitrariness;

competition;

accountability;

value for money;

proper delegation of authority.

The Supreme Court has repeatedly emphasised that governmental contracts and public procurement cannot be administered arbitrarily.

In Tata Cellular v. Union of India (1994), the Supreme Court explained the principles governing judicial review of government contractual decisions, particularly concerning fairness, rationality and procedural propriety.

In renewable-energy procurement, judicial review may therefore arise where:

tender conditions are discriminatory;

eligibility requirements are irrational;

bids are evaluated contrary to the tender;

authorities favour a particular bidder without lawful basis;

procurement is cancelled arbitrarily;

statutory approval is bypassed.

14. Regulatory Approval and Tariff

Where procurement involves a distribution licensee, regulatory approval may be required depending upon the applicable legal framework.

Section 63 of the Electricity Act is especially significant for tariff-based competitive bidding.

The regulatory framework distinguishes between:

tariff determination under Section 62

and

tariff adoption following competitive bidding under Section 63.

The MCD waste-to-energy litigation illustrates how municipal procurement can become connected with regulatory tariff approval and competitive bidding. (Indian Kanoon)

15. Case Law on Renewable Procurement

1. Gujarat Urja Vikas Nigam Ltd. v. Renew Wind Energy (Rajkot) Pvt. Ltd. (2023)

The Supreme Court considered renewable purchase obligations under Gujarat's renewable-energy regulations. The framework required specified entities to procure renewable electricity and provided mechanisms for compliance.

Principle: Renewable procurement obligations can be created and enforced through regulations made under the Electricity Act. (Indian Kanoon)

2. M/s Brihanmumbai Electric Supply & Transport Undertaking v. Maharashtra Electricity Regulatory Commission (APTEL, 2013)

The case concerned BEST's position as a municipal corporation/local authority and electricity distribution undertaking, including renewable purchase obligations.

Principle: A municipal electricity undertaking operating as a distribution licensee remains subject to the applicable electricity-regulatory framework, including renewable procurement requirements. (Indian Kanoon)

3. Hindustan Zinc Ltd. v. Rajasthan Electricity Regulatory Commission (2015)

The Supreme Court considered renewable-energy obligations imposed upon captive generators and open-access consumers and the regulatory authority to impose consequences for non-compliance.

Principle: Renewable-energy obligations can extend beyond traditional distribution licensees where the relevant regulatory framework lawfully identifies other obligated entities. (Indian Kanoon)

4. Timarpur-Okhla Waste Management Co. Ltd. v. Delhi Electricity Regulatory Commission (APTEL, 2015)

The dispute concerned waste-to-energy generation and whether electricity generated under an agreement could be utilised for fulfilment of a distribution licensee's renewable purchase obligation.

Principle: The contractual and regulatory conditions governing renewable-energy procurement and REC/RPO treatment must be carefully distinguished; the existence of a power-sale agreement does not automatically establish that electricity qualifies for another entity's RPO compliance. (Indian Kanoon)

5. Municipal Corporation of Delhi v. Gagan Narang (Supreme Court, 2025)

The case involved MCD's tariff-based procurement process for a waste-to-energy project and the relationship between municipal procurement, distribution licensees and renewable purchase obligations.

Principle: Municipal waste-to-energy procurement can operate within the statutory electricity framework and may involve competitive bidding, regulatory tariff processes and allocation of renewable electricity to distribution licensees. (Indian Kanoon)

16. Major Legal Issues

Municipal renewable procurement may generate disputes concerning:

A. Procurement jurisdiction

Whether the municipality or electricity regulator has authority over the procurement.

B. Tender validity

Whether the tender process satisfies public-procurement principles.

C. RPO attribution

Whether electricity generated by a municipal project can be counted toward the RPO of a distribution licensee.

D. Tariff approval

Whether the tariff requires determination or adoption by the regulatory commission.

E. PPA enforceability

Whether the municipality can terminate, renegotiate or modify a renewable PPA.

F. Grid connectivity

Whether the project satisfies technical and regulatory connectivity requirements.

G. Environmental approvals

Whether the renewable project requires environmental clearance, consent or waste-management approvals.

H. Renewable attributes

Who owns RECs and other environmental attributes.

I. Payment security

How the municipality protects the generator against delayed payment.

J. Change in law

How changes in taxes, regulations, renewable-energy obligations or grid charges affect the contractual tariff.

17. Governance Model for Municipal Renewable Procurement

A sound municipal procurement framework should contain:

Municipal Energy Plan → Demand Assessment → Renewable Target → Legal Authority → Procurement Strategy → Tender/RFP → Competitive Selection → Regulatory Approval → PPA → Project Development → Grid Connection → Energy Accounting → RPO/REC Verification → Audit

This creates a chain of accountability from policy formulation through actual electricity consumption.

18. Importance for Smart and Sustainable Cities

Municipal renewable procurement can support:

lower-carbon municipal operations;

energy-cost management;

energy security;

waste management;

distributed generation;

resilience of essential services;

electrification of public transport;

solar-powered water infrastructure;

climate commitments;

improved municipal energy planning.

Current CERC regulations also demonstrate the increasing sophistication of India's renewable-electricity regulatory architecture, including renewable tariffs and REC regulation. (CERC)

19. Conclusion

Municipal Renewable Energy Procurement is not simply the purchase of green electricity. It is a legally structured process involving municipal authority, electricity regulation, public procurement, environmental compliance, contractual governance and renewable-energy accounting.

The most important legal distinction is between a municipality acting merely as an electricity consumer and a municipal undertaking functioning as an electricity distributor or another legally recognised obligated entity.

The cases involving BEST, Hindustan Zinc, Timarpur-Okhla, Gujarat Urja, and particularly Municipal Corporation of Delhi v. Gagan Narang demonstrate the developing relationship between municipal governance and renewable-energy procurement. (Indian Kanoon)

Ultimately, a legally robust municipal renewable procurement system requires transparent competitive procurement, clearly allocated renewable attributes, regulatory compliance, enforceable PPAs, proper tariff treatment, environmental approvals and continuous monitoring of actual renewable-energy delivery and RPO compliance.
