Powering Mumbai: High Court Overcomes Green Hurdles for Critical Energy Link

In a landmark decision reflecting the delicate balance between urban infrastructure expansion and environmental stewardship, the Bombay High Court has granted approval to Adani Electricity Mumbai Infra Ltd. (AEMIL) to proceed with its High Voltage Direct Current (HVDC) transmission project. The initiative, aimed at bolstering Mumbai's buckling power capacity, requires the felling of mangroves—a move that triggered intense scrutiny under the court's own established environmental guidelines.

The Power Crisis Behind the Project

The 1,000 MW HVDC link between the Kudus EHV substation and Aarey EHV substation is not merely a commercial project; it is a vital lifeline for Mumbai’s burgeoning energy demands. Following a partial grid failure in October 2020, a High-Power Committee recommended the scheme on a priority basis. However, the path to implementation was blocked by the presence of mangroves in the Vasai and Kaman creek areas, which are protected under strict judicial oversight dating back to the 2006 Public Interest Litigation (PIL) against mangrove destruction.

Arguments: The Clash of Public Utility versus Ecology

The petitioner, AEMIL, argued that the project is a fundamental necessity, supported by the Maharashtra Electricity Regulatory Commission (MERC), to prevent future grid instability. The company committed to compensatory afforestation—planting five times the number of mangroves removed—and emphasized that laying underground cables through horizontal directional drilling (HDD) would mitigate surface ecological impact.

Conversely, the Bombay Environmental Action Group (Respondent No. 8) challenged the proposal, pointing to inconsistencies in the reported number of mangroves slated for clearing and raising concerns over the impact on vulnerable species in the Sanjay Gandhi National Park and Tungareshwar Wildlife Sanctuary. They invoked the Supreme Court’s recent focus on environmental protection in M.K. Ranjitsinh vs. Union of India , urging the court to prioritize biological integrity over industrial development.

The Court’s Reasoning: Navigating the 'Public Trust'

The bench, led by Chief Justice Alok Aradhe and Justice Bharati Dangre, clarified that while the State has an imperative duty to preserve mangroves under the 'Public Trust Doctrine,' this does not create an absolute bar on projects of manifest public importance.

The court noted that the expert committee's recommendations, including those from the National Board for Wildlife (NBWL), had already accounted for the project's ecological footprint. Critically, the court distinguished this case from the Supreme Court precedent regarding the Great Indian Bustard, noting that the protected species cited in that verdict were not present in the affected creek areas.

Key Observations

The High Court’s order emphasized that environmental protection and progress must move in tandem:

• "The mangroves cannot be permitted to be destructed by the State for private, commercial or any other use unless the Court finds it necessary for the public good or public interest."
• "In exercise of powers under Article 226 of the Constitution of India, this Court cannot sit in an appeal over the recommendation/decision taken by the various Committees comprising of Experts."
• "The project of construction of electricity transmission line is critical for the city of Mumbai as the existing capacity of transmission corridor is not sufficient to carry further power into the city."
• "The need for sustainable development and the requirement to maintain the environment must strike a balance."

Final Verdict: A Green Light under Strict Watch

The High Court concluded that the petitioner had secured all necessary statutory clearances from the MOEFCC, the MCZMA, and wildlife authorities. The court allowed the project to proceed, subject to a formal undertaking by AEMIL to strictly adhere to all mitigation conditions, including the five-fold compensatory plantation ratio.

This ruling underscores a pragmatic approach in Indian environmental jurisprudence: while the protection of mangroves remains a non-negotiable directive, courts remain willing to facilitate essential public utilities when backed by expert vetting, thorough environmental management plans, and a proven, overriding public interest.
