J.R.W. Utility Public Company Limited was founded on 2 November 1993 with initial registered capital of THB 1,000,000 to conduct business related to telecommunication. In the beginning, the Company’s major work was subcontracting for the construction of transmission line systems, transmission towers, and renovating stations to install telecommunication equipment.
Later in 2008, the Company deviated its business structure from labor-intensive, which involved communication networking, such as subcontracting for installation of towers and cables, design and procurement, installation, commissioning, and consulting telecommunication networking and information technology (total solution)—for example, designing and procuring equipment for main switching center, contracts on switching center equipment installation, subcontracting IP Broadband equipment installation, subcontracting signaling equipment installation related to 3G and 4G systems, mobile network, and Wi-Fi network, as well as software systems related to telecommunication systems, information technology, and other communication systems.
In 2014, the Company saw an opportunity and demand in designing and installing other systems in addition to the telecommunication systems and information technology.
To become a system integrator in various businesses, the Company has started the electrical system contractor business and started with a contractor service for the 115kV substation equipment for the Future Park Rangsit shopping center project. After that, the Company continuously received more electrical contractor projects, including the construction of substations. The first project was a construction project of a 115kV substation in Hi-Tech Industrial Estate, Bang Pa-in, Ayutthaya Province. In addition, the Company also undertakes the construction of high-voltage transmission lines to connect to the Electricity Generating Authority (EGAT) and many other Industrial Users (IU) customers.
