Bualuang Securities estimates that investment in the data center business is the most significant among industries applying for BOI promotions, with a total investment value of over THB 700 billion. This project is expected to be a positive supporting factor for power plant stocks, due to the significant projected increase in electricity demand, which is expected to reach around 3–4 GW by 2028.
The benefits from such investments can be divided into two main parts: First, the auctioning of new power plants to support increasing electricity demand, especially in the Eastern Economic Corridor (EEC), which will help reduce transmission system costs. Featured and recommended stocks in this group are GULF and GPSC. Second, companies related to the construction and extension of power transmission systems to support network expansion, such as Gunkul Engineering PCL (SET: GUNKUL).
Furthermore, there are sectors receiving indirect benefits from data center expansion, including businesses supplying water in the EEC area due to rising water demand. Beneficiary stocks likely to gain include WHA Utilities and Power PCL (SET: WHAUP) and Eastern Water Resources Development and Management PCL (SET: EASTW).
