PT Makmur Sejahtera Wisesa is developing a captive mine mouth power station at Tanjung, South Kalimantan, that will provide power to Adaro Indonesia's coal mining operations, replacing expensive diesel generators, when it comes on stream in 2012, and reducing Adaro's dependency on diesel fuel.

The power station comprises 2 x 30 MW units which will be fuelled from Adaro's Wara deposit and will have a net power output guaranteed at 52.5 MW with up to 5 MW of this output being reserved for supply to the local community with the balance available for Adaro Indonesia's operational needs

Only equipment from long established and reputable manufacturers was considered. The steam turbine generators are being supplied by Siemens and the boiler by BHEL of India. Lurgi's Circulating Fluidised Bed (CFB) technology was utilized in the boiler design and this will allow the plant to achieve high levels of availability, up to 90% even when using Adaro's low energy, high moisture Wara coal.
