Mitsubishi Power to Provide GTCC Equipment for Lamma Power Station

The Hongkong Electric Company (HK Electric) placed an order with Mitsubishi Power for natural-gas-fired GTCC power generation system equipment for Lamma Power Station’s 380 MW Unit 13, which is scheduled to begin operation in early 2029. Mitsubishi Power previously completed GTCC equipment orders for Units 10, 11, and 12 in July 2015.

In terms of the equipment included in HK Electric’s order, Mitsubishi Power will manufacture and supply its M701F gas turbine, a steam turbine, a heat recovery steam generator (HRSG), and a selective catalytic reduction system. The HRSG will be manufactured by Mitsubishi Generator Co.—a new company in the Hyogo Ward of Kobe City, Japan, formed on April 1 through an integration of the power-generator systems businesses of Mitsubishi Heavy Industries and Mitsubishi Electric.

“HK Electric is one of Hong Kong's leading power providers and the sole electricity provider to Hong Kong Island and Lamma Island,” said a representative of HK Electric. “Mitsubishi Power has had business relations with HK Electric for many years, having delivered numerous power generation system core components—including gas turbines, steam turbines and boilers—for the Lamma Power Station. It can be said that this latest order also reflects our assessment of the performance and proven track record of Mitsubishi Power products.”

The planned GTCC power generation facilities will be built on Lamma Island located southwest of Hong Kong Island, adjacent to the current Units 9, 10, 11, and 12. These facility build-outs are part of a large-scale project aligned with the Hong Kong government’s policy to increase the ratio of gas-fired power generation. Once in operation, the new GTCC facility will help to meet the requirements for Hong Kong Island’s significant power demand.

In February of 2024, Mitsubishi Power received a core equipment order for the third generation facility to be built at the Navoi power plant (Navoi 3) in the Republic of Uzbekistan. Operated by JSC Thermal Power Plants, Navoi 3 will now be powered with an M701 J-series air-cooled (JAC) gas turbine to generate 600 MW of electric power and 200 Gcal/h of heat. Commercial operation with Mitsubishi’s GTCC system is expected to begin in 2026.

In addition to delivering gas and steam turbines, Mitsubishi Power will design, procure, manufacture, and commission the core components for the power generation facilities and major auxiliary equipment, including air-cooled condensers and gas compressors.

Powered by a different M-series gas turbine, the M501 JAC, PowerSouth Energy Cooperative and Mitsubishi Power announced the commencement of operations at the Lowman Energy Center (LEC) in October of last year. The LEC is a 693 MW combined-cycle power plant that produces energy sufficient to power 300,000 homes per year, and is replacing the 556 MW Charles R. Lowman coal-fired power plant in Leroy, AL.

“At maximum output, the LEC offers 693 MW of reliable, around-the-clock power that will meet the needs of our distribution members for decades,” said Gary Smith, PowerSouth President and CEO. “That capability is important to our mission of reliability and affordability, which are being challenged by a rapid push toward intermittent, renewable generation.”
