INOX Air Products (INOXAP), India’s largest manufacturer of industrial, medical, and electronic gases, has signed a 20-year Build-Own-Operate (BOO) agreement with Premier Energies, one of India’s leading integrated solar cell and module manufacturers. Under this agreement, INOXAP will install and commission a cryogenic Air Separation Unit (ASU) to supply 7,000 Nm³/h of 5N-grade Gaseous Nitrogen and 250 Nm³/h of 6N-grade ultra-high purity Gaseous Oxygen, along with other liquid products, to Premier Energies’ greenfield solar cell manufacturing facility in Naidupeta, Andhra Pradesh. The ASU is scheduled for commissioning next year.

This collaboration further strengthens INOXAP’s four-year partnership with Premier Energies, which has seen multiple long-term on-site gas supply agreements and installations of cryogenic plants. INOXAP currently operates two 750 Nm³/h and one 1,000 Nm³/h Nitrogen generators at Premier’s Hyderabad facility, and has also started supplying electronic-grade gases for the company’s 3GW and upcoming 4GW solar PV cell manufacturing units.

Commenting on the agreement, Siddharth Jain, Managing Director, INOX Air Products, said, “We are proud to partner with Premier Energies to further India’s solar ambitions. This long-term agreement marks a key milestone in strengthening India’s solar manufacturing ecosystem by ensuring a reliable and sustainable supply of high-purity industrial gases. This will be India’s first integrated ASU dedicated to the solar cell manufacturing industry, capable of producing both ultra-high purity Nitrogen and Oxygen. With this development, we are enabling advanced technology adoption while reinforcing our commitment to accelerate India’s clean energy transition.”

Surender Pal Singh Saluja, Chairman, Premier Energies, added, “INOX Air Products has been our trusted partner in our journey toward clean energy leadership. As we strengthen India’s renewable energy manufacturing capabilities, this partnership underlines our shared vision for a sustainable, self-reliant future. We are confident that this new chapter in our collaboration will take our joint efforts to greater heights.”
