Technology group Wärtsilä has signed a second renewal of its Guaranteed Asset Performance  agreement with Indonesian state-owned mining company PT Aneka Tambang. Wärtsilä has had a full Operation and Maintenance agreement with Antam since the power plant’s commissioning in 2005, and a GAP agreement since 2017. This latest agreement renewal order was booked by Wärtsilä in June 2023.

The captive power plant supplies 60 percent of the electricity needed to operate the Antam ferronickel mine and ore processing plant located in Pomalaa in Southeast Sulawesi. The 137 MW plant was delivered by Wärtsilä under an engineering, procurement and construction contract. It operates with eight Wärtsilä 50DF dual-fuel engines.

“We appreciate the ongoing support that Wärtsilä has delivered since the power plant was commissioned. This support is provided with both remote monitoring and onsite advisors, and it ensures that we have a reliable supply of energy, which is essential for us to reach our production targets,” said Desryantho Tandi, Diesel Power Plant Manager at Antam.

“This agreement renewal emphasises the importance of long-term customer relations. A high level of trust and understanding benefits both companies. Through working in close cooperation, we can ensure operational efficiency, while the agreement provides cost predictability,” commented Erwin Vanderkerff, Director, Regional Operations Australasia at Wärtsilä.

In addition to remote monitoring and on-site advisory services, the renewed agreement also includes a full power management system, along with a spare parts supply for the engines and auxiliaries. Furthermore, Antam benefits from the latest design and upgrade information, expert technical advisory, analysis and audits, as well as improvement recommendations for the installation.
