Madras High Court Reserves Judgment in ₹397 Crore Tangedco Transformer Corruption Case
The Madras High Court has concluded hearings and reserved its order on two Public Interest Litigations (PILs) that allege massive corruption amounting to ₹397 crore in the procurement of transformers for the Tamil Nadu Generation and Distribution Corporation (Tangedco). The alleged irregularities occurred during the tenure of V Senthilbalaji as the state's electricity minister.
Bench Concludes Final Hearing
The first bench, comprising Chief Justice Sushrut Arvind Dharmadhikari and Justice G Arul Murugan, wrapped up the final arguments on Wednesday and formally reserved their orders. This development marks a crucial phase in the legal proceedings surrounding these serious corruption allegations.
Petitioners' Allegations of Systematic Corruption
The PILs were filed by Arappor Iyakkam, a prominent NGO, and E Saravanan, deputy secretary of the AIADMK advocates wing. Their petitions center on accusations that Tangedco manipulated tender processes for transformer procurement between 2021 and 2023.
The petitioners presented several key allegations:
- Ten separate tenders worth ₹1,182.88 crore were floated in a biased manner for procuring 45,800 transformers
- Thirty-six different bidders quoted identical prices for transformers, suggesting collusive bidding and cartelization
- Tangedco allegedly ignored this price uniformity in seven separate tenders
- These actions reportedly violated the Tender Transparency Act and caused a ₹397 crore loss to the state exchequer
Specific Pricing Irregularities Cited
The petitioners provided detailed evidence of pricing discrepancies. They claimed that 500 kVA transformers, which should have cost approximately ₹7.89 lakh each, were procured at an inflated price of ₹12.49 lakh per unit through the tender process. This represents a substantial 58.3% price increase that cannot be justified by normal market conditions or technical specifications.
Based on these findings, the petitioners filed an official complaint on July 6, 2023, requesting the formation of a Special Investigation Team (SIT) to conduct a time-bound, court-monitored investigation into the alleged corruption.
Tangedco's Defense and Counterarguments
The Tamil Nadu Power Distribution Corporation Ltd (TNPDCL), representing Tangedco, strongly opposed the PILs during the hearings. In their submission to the court, they characterized the petitions as "ill-advised, speculative and unsupported by admissible materials."
The corporation presented several counterarguments:
- The allegations of a scam in distribution transformer procurement are completely false and baseless
- Claims of financial loss to the exchequer lack any factual foundation
- The petitioners' comparisons involve dissimilar products with different technical specifications
- There is a fundamental misunderstanding of Tangedco's procurement procedures and technical requirements
The TNPDCL emphasized that proper procurement protocols were followed throughout the tender process and that all technical specifications were appropriately considered in the transformer acquisitions.
Awaiting the Court's Decision
With the hearings now concluded, all parties await the Madras High Court's final order. The court's decision will determine whether the allegations warrant further investigation through an SIT or if Tangedco's defense successfully addresses the corruption claims. This case has significant implications for transparency in public procurement and accountability in state-run utilities.
