MHI Receives Large-Scale Natural Gas-Fired GTCC Power Plant Order
Mitsubishi Heavy Industries, Ltd. (MHI) has received a full-turnkey order for a 750 MW natural gas-fired gas turbine combined-cycle (GTCC) power plant from PT. PLN (Persero), Indonesia's state-owned electricity company. The project is to construct a new GTCC power plant on the premises of existing Tanjung Priok Power Plant, located approximately 10 kilometers northeast of the central part of Jakarta, targeting expansion of the power station's generation capacity under a financing arrangement by Official Development Assistance (ODA) of Japan. The plant is slated to go on-stream in November 2011.
For the GTCC plant on order, MHI will supply two M701F gas turbines, two heat recovery steam generators (HRSG), one steam turbine and the balance of plant (BOP). Mitsubishi Electric Corporation will supply the generators, and AREVA T&D will provide the substations and power transmission facilities. Mitsubishi Corporation will handle the trade particulars.
In Indonesia, electricity demand has been increasing sharply along with economic growth, and as a result West Java, the region centered on Jakarta, in particular suffers from chronic power shortages. In response, in order to ease the tight power supply situation PLN has been focusing on new power plant constructions as well as expansion and repowering of the existing plants.
With GTCC type power generation, gas and steam turbines are used in combination to generate electricity in two stages, utilizing high- temperature exhaust gas from the gas turbine. This configuration enables GTCC power plants to achieve higher thermal efficiency than non-GTCC plants such as conventional boiler steam turbine plants. Higher efficiency means that GTCC plants reduce fuel consumption relative to electricity output and emit less CO2, thus making them more environmentally friendly.
