Indonesia: Working closely with PT Rekayasa Industri, an Indonesia Engineering, Procurement and Construction (EPC) company and their customer, PT Supreme Energy, ABB engineered, manufactured, supplied, installed and commissioned a prefabricated gas-insulated substation, which was delivered on-site fully assembled and factory-tested.
"ABB Power Grids delivers fully integrated modular, preassembled solutions that support customer needs," says Niklas Persson, Managing Director of ABB's Power Grids Grid Integration Business Line. "Our compact and reliable substation saves installation time and reduces execution risks, which makes it a particularly suitable solution for remote geographical areas."
ABB's prefabricated GIS substations have an exceptionally compact footprint. They include control, protection and monitoring in a robust frame, which makes them an ideal element to support rapid grid expansions. The 150 kV unit with its protective housing is tailor-made for the harsh sulfuric environment of the volcanic Sumatran uplands. The integrated GIS is designed with air over-pressure system and air filtration systems to protect the GIS from the sulfuric air condition in the volcanic area.
The Indonesian archipelago is one of the most seismically active regions in the world, prone to strong earthquakes and powerful volcanic eruptions. It is also a reservoir of geothermal power resources, holding an estimated 40 percent of the world's geothermal potential.
