On 10 August GE announced the start of commercial operation for Chia Hui Power Corporation’s combined heat and power plant in Minxiong Township, in Chiayi County, the sixth-largest county in Taiwan. GE provided an HA turbine powered turnkey combined cycle plant covering the full plant lifecycle, including power generation equipment, analytics and controls software, and service agreements. The plant adds approximately 535 MW to the grid, and steam for district heating for the citizens of the Chiayi province. This is considered as a significant achievement in supporting Taiwan’s Renewable Energy Development Act (REDA) energy policy, which seeks to increase the gas-fired power ratio to 50% by year 2025. The Chia Hui project was also recognised with the ‘Best-in-Class for Safety and Health Management’ award in 2020 by Taiwan OSHA as a model site for Southern Taiwan and was approved by the Bureau of Energy Taiwan for commercial operation.
“The growth of gas power generation plays a critical role in facilitating Taiwan’s transition to a lower carbon future …” said Kent Chen, general manager of Chia Hui Power Corporation.
The power plant consist of a single generating block equipped with a GE’s 7HA.02 gas turbine powering an H65 generator, a STF-A650 steam turbine powering an H33 generator, and a heat recovery steam generator (HRSG). For this turnkey project, GE manufactured, delivered, and installed the equipment and will provide maintenance services for 10 years.
Overall plant performance will be monitored by GE’s Mark VIe Distributed Control System (DCS) software solution to help Chia Hui Power Corporation improve asset visibility, reliability, and availability while reducing operating and maintenance costs. Mark VIe is utilised for system-wide programming, configuration, trending, and analysing diagnostics. It provides a single source of time-coherent data at the controller and plant level to diagnose and adjust how a plant is operating in real time.
In addition, Chia Hui power plant will use ‘big data’ analytics to improve fleet performance and make smarter operational decisions. GE’s Digital Energy Predix Asset Performance Management (APM) software is there to improve predictive maintenance capabilities and the operational life of the power station. Data collected from sensors throughout the facility will be monitored and analysed 24/7 at GE’s Monitoring & Diagnostics Centre in Atlanta, GA, United States.
