The Board of Directors of Borosil Renewables has approved the revised expansion plan of 600 TPD at an estimated cost of INR 950 crores approximately.
The expansion is being undertaken through setting up two furnaces of 300 TPD each (SG-4 and SG-5), and are expected to be commissioned during October to December 2026, stated the company in a regulatory filing.
The company, which currently has an installed capacity of 1,000 TPD, has made the decision in anticipation of favourable market conditions post the government’s imposition of anti-dumping on imports of solar glass from China and Vietnam for five years, effective from December 04, 2024.
“The imposition of anti-dumping duty for a period of five years, effective from December 04, 2024, on the import of solar glass from China and Vietnam will establish a level playing field for domestic manufacturers. This policy measure is anticipated to foster rapid and significant growth in domestic solar glass manufacturing,” rationalised the company.
Earlier, the company planned to increase the capacity by 500 TPD with an investment of about INR 675 crore.
The project(s) will be financed by using a mix of equity, debt and/ or internal accruals, or through a mix of any or all of such means of finance, as may be appropriate or decided by the management.
The increase in capacity is expected to result in higher production volumes and sales, it said.
