The National Green Tribunal (NGT) has modified its interim order, allowing TANGEDCO to proceed with construction at the Ennore SEZ Thermal Power Plant for a period of four weeks.

Key Takeaways

  • NGT granted a 4-week conditional permission to TANGEDCO for Ennore plant work.
  • TANGEDCO must seek EC and CRZ clearance extensions from MoEF&CC within this window.
  • The project was previously halted due to the expiration of environmental clearances.
  • Next hearing is scheduled for August 24, 2026.

The southern bench of the National Green Tribunal (NGT) has granted a significant reprieve to the Tamil Nadu Generation and Distribution Corporation (TANGEDCO). The Tribunal has permitted the resumption of work at the Ennore SEZ Thermal Power Plant in Vayalur, Tiruvallur district, for a limited duration of four weeks.

The bench, led by Justice Pushpa Sathynarayana and expert member Prashant Gargava, had previously halted construction because the project's environmental clearance had expired on December 31, 2025. The Tribunal has now directed TANGEDCO to use this four-week window to aggressively pursue extensions for both Environmental Clearance (EC) and Coastal Regulation Zone (CRZ) approvals from the Ministry of Environment, Forest and Climate Change (MoEF&CC).

Why This Matters

BozokMedia analysis shows that this ruling highlights the tension between rapid infrastructure development and stringent environmental compliance. For a state like Tamil Nadu, which faces growing energy demands, any delay in critical power infrastructure can lead to significant economic repercussions and power shortages.

The temporary resumption of work serves as a procedural bridge to ensure that critical public infrastructure does not stall indefinitely due to administrative delays.

During the proceedings, TANGEDCO argued for the exclusion of 'litigation time' from the validity period of their clearances, citing a Ministry Office Memorandum. They contended that the years spent in legal battles before the Supreme Court and NGT should be treated as a 'zero period' and not count against their environmental mandate.

Historical Background

The Ennore-Manali industrial belt has long been a focal point for environmental litigation in India. Thermal power projects in this coastal region face intense scrutiny due to their potential impact on marine ecosystems and the air quality of the surrounding densely populated industrial zones.

Frequently Asked Questions

1. Why was the construction work stopped initially?
The work was halted because the original environmental clearance for the project had expired at the end of 2025.

2. What is the next step for TANGEDCO?
TANGEDCO must obtain formal extensions for EC and CRZ clearances from the MoEF&CC before the next hearing on August 24, 2026.

Did You Know?: The 'Zero Period' concept allows project proponents to reclaim time lost to judicial proceedings when calculating the remaining validity of environmental permits.
