Wärtsilä to build 128 MW power plant in Indonesia

The plant will power the Grasberg mine.

Wärtsilä has acquired contracts for a 128 MW power plant in Indonesia, ordered by PT Freeport Indonesia (PTFI), a leading mining company.

According to a media release, the extended engineered equipment delivery order comprises 14 Wärtsilä 34DF dual-fuel generating sets.

The first eight generating sets were ordered in June 2020, then the succeeding six generating sets in September.

Wärtsilä, in partnership with PT PP, will install, construct, and commission the power plant.

To be located at Amamapare, PTFI’s port site in Papua, Indonesia, the plant’s generated electricity will power the Grasberg mine via a 100 km long transmission line, as PTFI extends operations from open pit to underground mining of one of the world’s largest copper and gold deposits

“We have completed open pit mining at the Grasberg minerals district, and are now developing large-scale, high-grade underground mines,” said George Baninni, executive vice president of PTFI. “For this, it is critical that we have a reliable and efficient energy supply, and the Wärtsilä generating sets will deliver the power we need."

Wärtsilä’s 34DF engines can operate on a variety of fuels, and such flexibility will allow the plant to switch from running on Indonesian B30 biodiesel to natural gas when it becomes locally available, Wärtsilä said in a statement.

The equipment is scheduled for delivery between July and November 2021, with the first seven engines expected to be officially handed over in March 2022, and the remaining seven to follow in July 2022.
