Mitsubishi Power says this latest Rayong milestone marks the timely delivery of seven out of eight M701JAC units across two 2650 MW combined cycle power plants, in Rayong and Chonburi (Gulf Sriracha facility, operated by Gulf SRC Company Limited), with a total installed capacity of 5300 MW. Anticipated to be fully operational by autumn 2024, all eight units of the completed power plants will support the electricity needs of key industrial and economic hubs in the eastern region of Thailand.
Mitsubishi Power says it has also successfully begun operation of one of two M701JAC gas turbines in a 1400 MW natural gas fired combined cycle power plant being developed in Thailand by Hin Kong Power Co Ltd, a special purpose company jointly established by RATCH Group Public Company Limited and Gulf Energy Development Public Company Limited. The completion and full operation of the second unit here is scheduled for January 2025.
In Hong Kong, Mitsubishi Power is to supply combined cycle power plant equipment for Lamma unit 13, a natural gas fuelled power plant to be built by Hongkong Electric Co, Ltd (HK Electric) on Lamma Island, south west of Hong Kong Island. HK Electric is the sole electricity provider to Hong Kong Island and Lamma Island. The new unit, employing an M701F gas turbine, will have an installed capacity of 380 MW and is scheduled to enter operation in early 2029. The new plant will be located adjacent to the existing Lamma units 9, 10, 11 and 12, and the power generation equipment order follows on from previous similar orders for units 10, 11 and 12 in July 2015.
As well as the gas turbine for the new Lamma unit, Mitsubishi Power’s scope will include a steam turbine, a heat recovery steam generator, and a selective catalytic reduction system. The generator will be manufactured by Mitsubishi Generator Co Ltd, a new company headquartered in Hyogo Ward, Kobe City formed on 1 April by integrating the power generator businesses of MHI and Mitsubishi Electric Corporation.
Meanwhile, in Uzbekistan, Mitsubishi Power, is providing combined cycle equipment, including an M701JAC gas turbine, for the 600 MW/200 Gcal/h Navoi 3 CCGT cogeneration plant to be built by JSC Thermal Power Plants, the state electric power corporation of the Republic of Uzbekistan. It is expected to start commercial operation in 2026.
This is the third combined cycle equipment order received by Mitsubishi Power for the Navoi site, located about 360 km south west of Tashkent. Mitsubishi Power previously supplied GTCC power generation equipment for Navoi 1 and Navoi 2, which started operation in 2013 and 2019, respectively. As well as generating electricity, Navoi 3 will supply industrial steam and district heating to the Navoi Free Economic Zone.
In addition to supplying the gas and steam turbines for Navoi 3, Mitsubishi Power will handle the design, procurement, manufacture, and commissioning of the power plant’s other core components and major auxiliary equipment, such as air-cooled condensers and gas compressors, while the generator will be manufactured by Mitsubishi Generator.
Mitsubishi Power says it has received many orders for large-scale gas turbines in Uzbekistan, including JAC and F series machines. Navoi 3 is the 13th such order and the fifth for a JAC series gas turbine, “giving Mitsubishi Power a market share of about 90% for large-scale gas turbines in the country.” The company has also supplied smaller, H-25, gas turbines for a city-based distributed natural gas fired cogeneration facility being constructed in Tashkent.
