Gacl-nalco Alkalies & Chemicals

What Gacl-nalco Alkalies & Chemicals does

GACL-NALCO Alkalies & Chemicals Pvt. Ltd. (GNAL) is a private joint venture between Gujarat Alkalies and Chemicals Limited (GACL, 60% equity) and National Aluminium Company Limited (NALCO, 40% equity), incorporated on December 4, 2015, to operate a greenfield chlor-alkali complex at Dahej, Gujarat. GNAL produces caustic soda (288,000 MTPA design capacity), chlorine (255,600 MTPA), hydrogen (7,200 MTPA), hydrochloric acid (66,960 MTPA), sodium hypochlorite (12,240 MTPA), and a by-product dilute sulphuric acid (5,760 MTPA) using membrane cell technology, paired with a 130 MW (2x65 MW) captive CFBC coal-based co-generation power plant that supplies the energy-intensive electrolysis process.

The company's commercial model is anchored by a long-term offtake agreement with NALCO for approximately 200 TPD (around 73,000 MTPA) of caustic soda for alumina production, with the residual caustic soda and co-product slate (chlorine, hydrogen, HCl, sodium hypochlorite) sold B2B to industrial customers across India via pipeline (to Dahej neighbors), bulk tankers, and cylinders. Total project cost was Rs 2,300 crore, financed via Rs 690 crore promoter equity and Rs 1,610 crore bank debt (Punjab National Bank term loan, SBI GIFT City ECB since repaid, Gujarat State Financial Services loans, and Rs 500 crore of CCDs issued to IndusInd Bank in FY 2024-25).

GNAL is a relationship-driven, enterprise-only B2B supplier with no consumer marketing. Its moat rests on the captive power setup, single-site scale, long-term NALCO anchor offtake, PSU sponsorship (Government of Gujarat + Government of India), ISO/BIS certifications, and the Dahej pipeline logistics edge. Operations are supported by an ERP system implemented in July 2020, with debt being progressively deleveraged (SBI ECB fully repaid in FY 2024-25) and ongoing refinancings via GSFS and IndusInd Bank CCDs.

Revenue model

1. Caustic Soda Sales: Production and sale of caustic soda (sodium hydroxide) as 48% lye (liquid) or flakes (solid). Approximately 200 TPD of caustic soda is earmarked for supply to NALCO for its alumina production facilities, with the rest available for other customers.
2. Chlorine Sales: Chlorine is supplied as gas through pipelines and as liquid in 900 Kg, 100 Kg and 50 Kg containers. Chlorine is a co-product of caustic soda production via electrolysis of brine.
3. Hydrogen Sales: Hydrogen is supplied as gas through pipelines and as compressed gas in 5, 6, 7 Nm3 cylinders/cylinder banks. Hydrogen is a co-product of caustic soda production.
4. Hydrochloric Acid Sales: Hydrogen chloride is supplied as gas through pipelines and as acid/30% solution in bulk containers as well as 25, 50 Kg containers. Produced by burning hydrogen and chlorine together.
5. Sodium Hypochlorite Sales: Sodium hypochlorite (NaOCl), commonly known as soda bleach, is produced by adding chlorine into caustic soda solution. Used as bleaching agent, disinfectant, and water treatment chemical.
6. Power Generation (Captive Use): The 130 MW coal-based captive power plant (2 x 65 MW) generates power primarily for captive consumption by the caustic soda plant operations, ensuring self-sufficiency in power supply.
