Actually, when talking about stocks that offer relatively stable returns and good passive income, power plant stocks must be on the key list. Why is that? Because electricity is something everyone needs every day. Whether the economy is good or bad, demand still exists. Therefore, power generation businesses have fairly predictable income.

When looking at the market, you'll see that GULF has the highest market value at 795.55 billion baht, followed by GPSC at 109.26 billion baht, and RATCH at 67.97 billion baht. These stocks are all major electricity producers in the country, with long-term power purchase agreements with the government, which makes their income quite stable.

What’s interesting is that most power plant stocks have P/E ratios that are not too high, such as GULF, which ranges from 8.4x to 32.1x. This is considered quite reasonable. It indicates that the market does not assign a high premium to these stocks, but they have a history of consistent dividend payments, making them suitable for investors seeking regular income.

For investing in power plant stocks, there are two options. The first is to buy through a regular Thai stockbroker, trading on the stock exchange, with a minimum of 100 shares. For example, if you buy GULF at 54 baht, you need 5,400 baht. The second is to trade via foreign brokers using CFDs, which have the advantage of leverage and allow trading both upward and downward. The downside is that it carries higher risk.

For long-term perspectives, actual power plant stocks are suitable for diversification in a portfolio because they are considered "safe" stocks in the investment world. They are called Defensive Stocks. Even if the market is volatile, power plant stocks can still provide steady returns and dividends. This is why many people see power plant stocks as valuable investments regardless of the market cycle.
