Alembic Pharmaceuticals Limited, an India-based pharmaceutical manufacturer, has received supplementary invoices totaling INR 42,16,82,065 (≈ $4.64 million) from Madhya Gujarat Vij Company Limited. These invoices cover charges related to the firm's rooftop PV system installation in Gujarat state. The company filed writ petitions in Gujarat High Court on December 16, 2025, naming State of Gujarat as opposing party to quash these disputed claims. On December 19, 2025, the court ordered Alembic to furnish a bank guarantee for 35% of the amount, approximately Rs. 14.76 crore. The court classified supplementary invoices as preliminary assessment rather than final billing. Alembic must file formal representation to MGVCL within 4 weeks from December 19. No coercive actions like power disconnection or solar system sealing can occur for 2 weeks post-final assessment.
