A Yuchai 16VC 2400kW high-voltage containerized diesel generator set delivered and commissioned by Guangxi GCL China-Malaysia Distributed Energy Co., Ltd. in 2021 - rated 2400kW, directly connected to 10kV station service, serving as emergency standby and peak-shaving power for the park's energy station alongside its 2x75MW SGT-800 gas-steam combined-cycle CCHP plant.
1. Background: The China-Malaysia Qinzhou Park and GCL China-Malaysia
In the China-Malaysia Qinzhou Industrial Park (CMQIP) - a national-level park jointly built by China and Malaysia, facing the Beibu Gulf - stable and green energy supply is vital to nearly 300 enterprises based there.
Guangxi GCL China-Malaysia Distributed Energy Co., Ltd. ("GCL China-Malaysia"), established in 2015, is the park's sole integrated energy service provider, delivering combined cooling, heating and power (CCHP).
GCL China-Malaysia is a mixed-ownership enterprise invested by GCL Group (via GCL Energy Technology, 002015.SZ) together with the Guangxi China-Malaysia park platform company.
Its Phase I - two 75MW-class Siemens SGT-800 gas-steam combined-cycle units with total investment of about RMB 1.02 billion - achieves CCHP with comprehensive energy efficiency above 80% and annual standard-coal savings of roughly 200,000 tonnes.
2. Why This 2400kW High-Voltage Container Set Is Needed
During planned maintenance of the combined-cycle main units or short-term external grid disturbances, the continuous power supply to critical auxiliaries and control systems must not be interrupted - a loss of power would force heat-recovery boilers, circulating water pumps and instrumentation offline, threatening station safety.
In 2021 GCL China-Malaysia commissioned the Yuchai 16VC 2400kW high-voltage containerized diesel set for emergency standby and peak shaving, becoming the station's "safety anchor."

4. Operational Value Since Commissioning
Since 2021 the unit has remained in a hot-standby state:
On grid loss it self-starts rapidly to supply emergency power to critical auxiliaries such as heat-recovery boiler feed pumps and instrumentation, supporting the station's black-start capability. Maintenance is convenient, spare parts are standardized, and interfaces for future multi-unit parallel operation and capacity expansion are reserved.
From the "2x75MW combined-cycle main units" to the "2400kW high-voltage container standby set," GCL China-Malaysia's architecture exemplifies a "main force plus safety net" synergy - offering a replicable reference for similar coastal industrial-park energy stations.
