Indonesia: Semen Indonesia has commenced the construction of a 30.6MW waste heat recovery power generator (WHRPG) in an effort to reduce the company's electricity costs.

The facility will be located at Semen Indonesia's cement plant in Tuban, East Java and will cost US$52.9m. The power plant will make use of the heat generated from the cement plant. Construction is expected to take 26 months. Operations are expected to start in the second half of 2016.

In 2013, Semen Indonesia signed a memorandum of understanding (MoU) with Japan's JFE Engineering Corporation for the WHRPG construction. "This will be the first project in Indonesia where waste heat in the whole area is utilised to supply the power plant," said Semen Indonesia president director Dwi Soetjipto. The company has applied similar technology at its Indarung facility in Padang, West Sumatra, on a smaller scale. Indarung power plant's capacity is 8.5MW and it started operation in 2011.

Once the power plant is completed, Semen Indonesia will be able to supply about one third of the company's energy needs at the Tuban plant. It could save US$9.95m/yr in electricity costs.
