I just noticed that these power utility stocks still remain an interesting option for a long-term investment portfolio. This is because power plant businesses generate relatively stable income, and importantly, they consistently pay good dividends.

In Thailand, there are 8 major power utility stocks by market value, led by GULF (795.55 billion baht), followed by GPSC (109.26 billion baht), RATCH (67.97 billion baht), and EGCO (63.44 billion baht). The latest closing price of GULF is 54 baht, with a P/E ratio ranging from 8.4 to 32.1 times, which is quite attractive.

What makes power utility stocks worth investing in is that this business has stable cash flow, and its performance is not highly volatile. Moreover, these companies often pay high and consistent dividends, making them suitable for those seeking passive income from their portfolio.

Companies like GULF are involved in power generation, gas, renewable energy, and infrastructure. GPSC operates in the production and distribution of electricity, steam, and other utilities. RATCH is a major private power producer, with EGAT holding about 45% of its shares, reflecting the stability of its structure and strategic role.

The reason to consider investing in power utility stocks is that this business is supported by the government through the Power Development Plan (PDP) and the Alternative Energy Development Plan (AEDP), ensuring long-term stability. Additionally, the global green energy trend continues to grow, presenting further opportunities for power stocks investing in renewable energy.

When selecting power stocks, several factors should be considered, such as the company's expansion strategy, power purchase agreements, contract durations, and future industry trends. For example, BCPG has a high P/E ratio (81.5 times) but focuses on clean energy, while EGCO has a lower P/E (12.4 times) and invests in the Asia-Pacific and North American regions.

If looking at power stocks for a long-term portfolio, it might be worth considering additional options, as they not only offer good dividends but also have growth potential from business expansion and the transition to clean energy—an ongoing trend that shows no signs of stopping.
