Supercritical expansion for Indonesia coal-fired plant

Indonesia’s state utility PLN is to build a 315 MW extension to an existing coal-fired power plant in the Kemiri district, Tangerang Regency, Banten Province.

Selected for the Lontar Extension Coal-Fired Steam Power Plant Project is a consortium composed of Japan’s Sumitomo Corp, US-headquartered Black & Veatch and Indonesia’s PT Satyamitra Surya Perkasa (PT SSP).

The Lontar expansion is to be built alongside the existing 945 MW plant (pictured), which came online in 2013.

For the project, Black & Veatch will be the principal EPC provider and technical lead. The company said it will also provide equipment supply, construction management and commissioning. Sumitomo will be responsible for the boiler and steam turbine supply, while PT SSP will construct the facility.

In a statement, Sumitomo said the boilers will be supplied by IHI Corporation, while the steam turbine and power generator will be supplied by Toshiba. “Adoption of this supercritical technology by a power plant with a capacity of 315 MW is unprecedented, and represents a new design that mainly employs Japanese technology,” the company said.
