Performance 2025
Operational Excellence
We continue to advance the development and improvement of energy generation efficiency, combined with application of technology. Consequently, in 2025 we achieved both efficiency and stability, with energy efficiency averaging 52.1 percent and availability factor 96.3 percent in combined-cycle cogeneration plants. Key projects are outlined below.
- The Digital Twin Project
A power plant management system, applied to combined cycle co-generation power plants, which serve as the main power source for the Smart Grid. The project objectives include:
1) Assessing cost-effectiveness and overall efficiency of electricity generation for Predictive Maintenance, to analyse machinery health and lifespan.
2) Facilitating timely maintenance planning before machinery failure occurs, preventing disruptions to the production process.
3) Collecting and organising data on production and operations.
It consists of the following systems:
- AI Machine Health Monitoring
Uses Artificial Intelligence (AI) technology to process operating data, analyse efficiency, production capacity, maintenance, and electricity sales. It supports management by increasing production efficiency and preventing equipment damage, resulting in reduced resource consumption and greenhouse gas emissions. This is in cooperation with REPCO NEX (SCG Chemicals). This year, it was expanded to a total of 22 projects, including ABP1R-2R, ABP3-5, ABPR1-5, BIP1-2, BPWHA1, BGPAT1-3, BGPM1R-2R, BPLC1R, PPTC, and SSUT1-2. - Continuous Performance Optimisation (CPO)
