Power Master II Holdings Co., Ltd. (6839.TWO), formerly known as Power Master International Investment Holdings Co., Ltd. and recently renamed Power Master Energy Co., Ltd., operates as a professional solar power system supplier and midstream service provider in Taiwan's renewable energy sector; the company delivers comprehensive one-stop solutions including project contract engineering, procurement, and construction (EPC) services; power plant investment and development; operation and maintenance management; energy storage systems; and trading of solar-related equipment and materials such as photovoltaic modules, brackets, and inverters. Founded in 1999 and headquartered at 8F., No. 651-3, Zhongzheng Road, Xinzhuang District, New Taipei City, Taiwan, it primarily serves customers in Taiwan with minor operations elsewhere and targets industrial, commercial, and utility-scale solar projects. In a significant recent change, the company underwent a name change in late 2023 to Power Master Energy Co., Ltd., reflecting its sharpened focus on energy technology services, alongside reporting earnings for the half-year ended June 30, 2024, and full-year ended December 31, 2023, amid a shift to lower net sales of NT$1.81 billion in 2024 from NT$2.19 billion in 2023 due to market dynamics in heavy construction and solar segments.
