Star Energy Corporation, a wholly owned subsidiary of the Taiwan Cogeneration Corporation (TCC Group), was established 28 years ago. With diversified operations and strong competitiveness, the company possesses a comprehensive EPC (Engineering, Procurement, and Construction) technical team that supports its parent company, TCC Group, in advancing power generation and engineering contracting businesses, providing customers with high-quality services. In recent years, in line with the government’s demanding goals of renewable energy policies, Star Energy has expanded into the markets of solar power, wind power, and geothermal power EPC projects as well as operation and maintenance services, further broadening its service scope.
Star Energy Corporation has been awarded the NT$1.919 billion (tax included) contract for the “Shu-Gu S/Y Civil Engineering EPC Project,” following a public tender held by the Southern Region Construction Division of TPC’s Transmission and Substation Engineering Department. The project was awarded through “Most Advantageous Tender” evaluation process, underscoring the company’s technical and commercial competitiveness in delivering large-scale infrastructure works.
The project schedule is divided into seven phases. Phase 1, with a duration of 240 calendar days, requires completion of the substation building’s elevation and floor plan review, acquisition of the building permit, and obtaining approval from the competent authority to commence construction. Phase 2 focuses on detailed design work. Phases 3 through 7 cover full-scale on-site construction and coordination of mechanical and electrical system installations.
This project aligns with the Phase I Grid Enhancement Program to lessen power flow on the 345kV Nanke–Hsingda transmission line and strengthen the power supply capacity of the Nanke Extra-High Voltage Substation (E/S), addressing the growing electricity demand in the Southern Taiwan Science Park. Due to the capacitive charging effects associated with the new long-distance 345kV underground cable, the Shu-Gu S/Y will be newly constructed and equipped with voltage compensation equipment to improve power quality.
The project site is located on the north side of Tainan Science Park (between Wuqiao 1st Road, Wuqiao Central Road, and Nanke North Road). TPC plans to construct a two-story above ground and one-story underground building, along with related internal cable tunnels. This project is part of TPC’s Phase 1 Power Grid Reinforcement Program, which includes the construction of a long-distance 345kV all-cable transmission line to strengthen the regional transmission network. It aims to reduce power flow on the existing 345kV Nanke–Hsingda line, enhance the Nanke E/S substation’s power supply capacity, and meet the future electricity demand growth of the Southern Taiwan Science Park. Considering the charging capacitance effect of underground cables, this project will include voltage compensation equipment to improve power quality. 
The project is led by Star Energy Corporation, building on the successful experience of the same team in the Guishe R/S and Nangang P/S EPC Projects. Team members include Ruentex Engineering and Construction, Ltd., a domestic leader in precast construction methods; architects Chang Chung-Yi and Huang Chun-Lung, pioneers of TPC’s precast design approach; and a collaboration with a well-known domestic construction company utilizing system formwork for on-site casting works. In actively responding to national policies promoting precast construction and circular economy, this project aims to set a new benchmark for Taiwan’s power infrastructure, shortening construction time, improving quality, advancing digitalized construction (the “four modernizations”), achieving net-zero emissions, and reducing environmental pollution.
To align with TPC’s grid connection schedule and address the current nationwide labor shortage, this project will introduce precast construction methods in substation building works. By leveraging the advantages of precast structures, the project seeks to overcome labor challenges, shorten construction duration, enhance construction quality and reliability, improve safety, reduce carbon emissions and waste, and ultimately provide TPC with significant time and quality benefits, while contributing to innovation and upgrading of substation structural design.
