Location

Odisha, India

The project involves the development of a greenfield silicon ingot and wafer manufacturing facility in Odisha, India, with a nominal production capacity of 10 GW per annum. The facility forms a critical upstream segment of the solar photovoltaic manufacturing value chain.

Planned across an approximately 200-acre site, the facility brings together the manufacturing environment, utilities, infrastructure and specialised systems required to support ingot and wafer production. The engineering is being developed from the Basic Engineering Design, which defines the process configuration, design basis, utilities and plant layout.

TCE’s Scope

TCE is providing multidisciplinary detailed engineering and complete 3D model development for the facility, with engineering spanning civil and structural, architectural, mechanical, piping, electrical, instrumentation and control systems. The scope integrates the manufacturing environment with the plant infrastructure and specialised utilities required for ingot and wafer production. This includes gas supply and argon recovery, chemical distribution, process exhaust and dust collection, compressed air, HVAC, process water, fire protection, water treatment, ETP and ZLD, UPW/DI water, cutting-water recycling, high-voltage power infrastructure and plant electrical distribution. TCE’s responsibilities also extend to utility controls, field instrumentation, raw-water systems and supporting communication, fire detection and security systems.

The engineering is being developed through staged 3D model reviews, enabling coordination across disciplines, equipment interfaces, utilities and supporting infrastructure as the project progresses.

Impact

The project contributes to the development of domestic manufacturing capability in the upstream solar PV value chain, with a 10 GW facility dedicated to silicon ingot and wafer production in India.

TCE’s multidisciplinary engineering brings the manufacturing environment, utilities, electrical infrastructure and specialised process-support systems together within a coordinated plant design. The project also adds to TCE’s engineering experience in solar ingot-to-wafer manufacturing and advanced manufacturing facilities.
