1. Introduction

This case examines whether a municipal corporation (specifically, the Municipal Corporation of Delhi, "MCD") can invoke Section 63 of the Electricity Act, 2003, to seek adoption of a competitively discovered tariff for a Waste-to-Energy (WTE) project. The Respondent, Mr. Gagan Narang, had challenged the orders of the Delhi Electricity Regulatory Commission ("DERC") on the ground that the MCD, being neither a generating company nor a distribution licensee, had no locus standi to seek tariff adoption under Section 63. The Supreme Court of India, in its decision, clarified the scope of Section 63 vis-à-vis local authorities and upheld the MCD’s authority to issue bids and approach the DERC for adoption of the discovered tariff.

The case also touches upon significant statutory interpretations concerning the Solid Waste Management Rules, 2016, the National Tariff Policy, and the interplay between environmental obligations and electricity sector regulations.

Key parties involved in this dispute include:

• The Municipal Corporation of Delhi ("Appellant-MCD")
• Gagan Narang & Ors. ("Respondent No. 1" and others)
• Delhi Electricity Regulatory Commission ("DERC")
• Appellate Tribunal for Electricity ("APTEL")
• Waste to Energy Research & Technology Council ("WTERT")
• Distribution Licensees in Delhi ("Discoms")

2. Summary of the Judgment

The Supreme Court allowed the appeals filed by the Municipal Corporation of Delhi and set aside the decision of the APTEL, which had held that the MCD could not seek tariff adoption under Section 63 of the Electricity Act, 2003. The Court restored the DERC’s orders dated March 6, 2023, and March 7, 2023, affirming that:

• The MCD, acting under its statutory duty to manage municipal solid waste, may conduct a tariff-based bidding process for setting up a WTE project.
• The appropriate State Commission (DERC, in this case) can validly approve and adopt a competitively discovered tariff under Section 63 of the Electricity Act, 2003, even if the initiating party is a local authority rather than a distribution licensee or generating company.
• This interpretation supports the broader public interest of efficient waste management and harnesses renewable energy opportunities in compliance with environmental and electricity statutes.

In essence, the Supreme Court adopted a purposive approach to harmonize the provisions of municipal solid waste management obligations under the Solid Waste Management ("SWM") Rules, 2016, with the Electricity Act, 2003, and Tariff Policy, thus clarifying that Section 63 of the Act is not limited to applications by distribution licensees or generating companies.

3. Analysis

a) Precedents Cited

Several pivotal precedents and statutory provisions were relied upon and scrutinized by the Court:

• Energy Watchdog v. Central Electricity Regulatory Commission & Ors. (2017) 14 SCC 80: This case established that, in the absence of specific bidding guidelines by the Central Government, the respective Electricity Regulatory Commission can exercise its general regulatory powers under Sections 79(1)(b) or 86(1)(b) of the Electricity Act, 2003, to adopt or determine tariffs.
• Jaipur Vidyut Vitran Nigam Limited & Ors. v. MB Power (Madhya Pradesh) Limited & Ors. (2024) 8 SCC 513: Confirmed that State Commissions are not mere “post offices” but play a critical role in balancing the interests of consumers, distribution licensees, and generators.
• Pune Municipal Corporation v. Sus Road Baner Vikas Manch & Ors. (2024) 9 SCC 1: While cited more generally for municipal obligations, it helped illustrate that municipal bodies carry statutory obligations to handle projects related to public infrastructure (e.g., waste management).
• Punjab State Power Corporation Limited & Anr. v. Emta Coal Limited (2022) 2 SCC 1: Emphasized the principle of literal interpretation of statutes—plain reading of legislation is paramount unless an absurd result follows.

The Supreme Court relied heavily on the principle that statutes such as the Electricity Act and the SWM Rules, 2016, should be harmoniously construed, rather than read in isolation or conflict.

b) Legal Reasoning

The Supreme Court’s reasoning can be broken down into the following key steps:

• Harmonious Interpretation: The Court emphasized reading Section 63 of the Electricity Act in conjunction with Sections 86(1)(b) and 86(1)(e). Section 63 allows adoption of a competitively determined tariff without limiting who may initiate the process. Meanwhile, Section 86(1)(b) requires the State Commission to regulate the entire electricity procurement process, and Section 86(1)(e) obligates it to promote renewable energy, including WTE projects.
• Municipal Obligation under SWM Rules, 2016: Rule 15(v)(b) of the SWM Rules mandates local authorities to facilitate the construction, operation, and maintenance of WTE facilities. Hence, the MCD has a direct statutory obligation to initiate and complete these projects.
• Scope of Section 63: Nothing in Section 63 suggests that only distribution licensees/generating companies can apply for tariff adoption. A restrictive interpretation would defeat the legislative intent of promoting renewable energy (particularly WTE).
• Importance of Transparency and Bidding Guidelines: Under Section 63, the Commission’s key function is to ensure that the discovered tariff is the product of a transparent, competitive bidding process following any relevant Central Government guidelines. The DERC duly examined MCD’s bidding process and had satisfied itself that transparency was maintained.
• Public Interest in Waste Management and Energy Generation: The Court stressed that these projects serve the dual societal benefit of addressing municipal solid waste disposal and producing renewable energy.

c) Impact

By clarifying that local authorities can indeed invoke Section 63 for tariff adoption under the Electricity Act, 2003, the Court effectively broadens the scope for public bodies to institute WTE or similar renewable energy projects. Some of the immediate and long-term effects include:

• Encouragement of WTE Projects: Municipalities with statutory mandates to manage solid waste can directly approach Electricity Regulatory Commissions for adoption of competitively discovered tariffs, thereby integrating waste management solutions with renewable energy policy.
• Strengthened Interplay between Environmental and Energy Laws: The judgment highlights that SWM Rules, 2016, the Environment (Protection) Act, 1986, and the Electricity Act, 2003, must all be considered in tandem. It supports the proposition that environmental obligations can be operationalized through electricity sector mechanisms.
• Enhanced Role of State Commissions: State Commissions must ensure the transparency and economic viability of all procurement processes under their regulatory ambit, whether initiated by Discoms, generators, or local authorities.

4. Complex Concepts Simplified

Section 63 vs. Section 62 of the Electricity Act, 2003

• Section 62: The Commission itself determines the tariff based on a normative or cost-plus approach.
• Section 63: The Commission “adopts” or approves the tariff if it is discovered through a transparent competitive bidding process in line with Central Government guidelines (if present). Essentially, the role of the Commission under Section 63 is to verify the fairness of the bidding framework rather than to fix the tariff directly.

Distribution Licensees (“Discoms”)

These are entities authorized to distribute electricity to end-users within a specified area. Under the National Tariff Policy, they are obligated to procure renewable energy, which includes energy from WTE sources.

Waste-to-Energy (“WTE”) Projects

WTE projects convert municipal solid waste into usable energy, typically electricity. They address two policy objectives simultaneously: environmental sanitation (reducing urban waste) and promotion of renewable power generation.

SWM Rules, 2016

“Solid Waste Management Rules, 2016” place responsibility upon local authorities to establish appropriate facilities for waste disposal, including WTE plants. These rules trace their authority to the Environment (Protection) Act, 1986, demonstrating how environmental laws dovetail with energy regulations.

5. Conclusion

The Supreme Court’s decision to allow the Municipal Corporation of Delhi’s appeal and reinstate the earlier orders of the DERC has significant implications for how local bodies can interact with the electricity regulatory framework. In essence, the Court has:

• Affirmed that Section 63 of the Electricity Act, 2003, may be invoked not only by generating companies and distribution licensees but also by municipalities/local authorities that are fulfilling statutory functions under environmental and municipal laws.
• Ensured that municipal corporations can integrate their waste management obligations with energy sector mandates in a legally robust manner.
• Emphasized the fundamental policy goal of promoting renewable energy and ensuring transparency in tariff determination processes.

Ultimately, this precedent strengthens the synergy between environmental law obligations (managing and processing solid waste) and energy regulation (encouraging renewable energy purchase obligations and fair tariff procurement). It underscores that statutory provisions must be read harmoniously, rather than in isolation, to ensure that public interest—particularly waste management, environmental protection, and renewable energy promotion—remains the driving force behind judicial interpretation.
