At 385 meters high, Tower 1 of Thamrin Nine will become the tallest building in Indonesia

Jakarta, the capital and largest city of Indonesia, has experienced rapid urbanization in recent decades, and today the city has more than 10 million inhabitants. This makes it the most populous city in South East Asia and the population density continues to increase.

Indonesian property development and management company, PT Putragaya Wahana (PGW), rose to the challenge and is currently developing a large-scale mixed use development complex, Thamrin Nine, in the heart of the city. Thamrin Nine covers an area of approximately 570,000 square meters, which is the equivalent of more than 100 American football fields. Upon completion, the complex will comprise a total of three high-rise towers for office and commercial use, a retail podium with a music hall, cinema, supermarket, sports hall, and a plethora of dining options. In addition to this, three residential buildings, two of which are low rise and one midrise will complete the development. The first tower to be built, Tower 1, will be ready for tenant fit-out in 2021. Tower 1 has an architectural height of 385 meters, comprising of 72 floors above and 6 floors below ground.

ABB is delivering power distribution solutions to ensure the reliability of the electricity supply in what will become the highest building in the country. Thamrin Nine will be the highest building in Indonesia and the Southern Hemisphere. Building and maintaining the electric power network in high-rise buildings places great demand on ensuring uninterrupted power supply to crucial systems and equipment, such as heating, ventilation, fire protection, air conditioning, and building control systems. The equipment used must provide maximum safety, reliability and energy-efficiency, and it should be easily adaptable to also meet changes in the future.

To meet these requirements, ABB is supplying 44 panels of UniGear ZS1 medium-voltage switchgear. In power distribution systems, switchgear is used to control, protect and isolate electrical equipment to ensure the reliability of the electricity supply. ABB’s UniGear can be safely operated in confined spaces as it meets the stringent requirements set for safety and internal arc protection. On top of offering a solution that was a perfect match with the technical specifications, ABB was also able to meet the customer’s tight delivery date requirements and reduce the switchgear delivery time by 25 percent.

“ABB is pleased to deliver our state-of-the-art technologies, integral to delivering reliable power supply, to the tallest building in Indonesia,” said Marco Tellarini, Global Product Group Manager in the Distribution Solutions business line. ‘With UniGear switchgear we were able to provide the design flexibility and system protection necessary to satisfy the customer’s unique project requirements.”
