TTDI was also awarded an EPC contract by Odisha Power Transmission Corporation Limited (OPTCL) to construct 220 kV substation adopting Gas Insulated Switchgears (GIS) on turnkey basis, which is scheduled to commence operation in June 2017. In India, the demand for UHV transformer is being spurred because of its efficiency when carrying massive amounts of electricity from power plant. The demand for GIS, which makes it possible to build smaller power substation, is also expected to increase in urban areas on the background of sky-rocketing property value.
