The national utility of Indonesia, PT PLN, has appointed a consortium between PT WIKA and TSK Electronica Y Electricidad to deliver a peaking power plant in North Sumatra, Indonesia.

The plant will be powered by 13 Wärtsilä 50SG natural gas engines, providing an output of around 240 MW.

Wärtsilä will deliver gensets and performance-related equipment to TSK in 2018 with the plant expected to be fully operational in the first half of 2019.

The Sumbagut-2 Peaker Power Plant will be the largest peaking plant with Wärtsilä technology in Indonesia and will be located next to the existing PLTMG Arun plant that was delivered by Wärtsilä and PT WIKA in 2015.

The plant will also be the first Wärtsilä project in Indonesia to use 50SG engines.

“This project is a significant step to establish a new business relationship with TSK for future endeavours and at the same time further nurture the long term relationship between PLN and Wärtsilä,” said Robert Stoor, Business Development Manager for South East Asia at Wärtsilä Energy Solutions. “Wärtsilä has a strong commitment to develop efficient power supply in Indonesia and enable a transfer to a more sustainable, affordable and reliable power system.”

Francisco Martín Morales de Castilla, managing director of Power & Industrial Plants at TSK Electronica Y Electricidad sais “there has been a shortage of electricity capacity in northern Sumatra for a long period”.

“As part of PLN’s long term electricity supply business plan, the utility has decided to install new peaking capacity in the region. The produced electricity will be supplied to the Sumatra grid.”
