The year 2026 is full of opportunities for leading Thai power plant stocks

Power utility stocks are considered an attractive investment option for those seeking a balance between performance and stability. Over the past year, these securities have continued to gain popularity among both new and experienced investors because electricity is essential in all aspects of life and the economy.

Why Power Utility Stocks Are a Safe Haven for Investors

Whether the market is thriving or in recession, the demand for electricity remains unaffected by economic cycles. This is why power utility stocks are viewed as defensive stocks, characterized by:

Stable and Predictable Income Business in power generation has recurring revenue from long-term power purchase agreements (PPAs), resulting in highly stable cash flows and consistent financial performance.

Consistent Dividend Payments Due to steady income streams, power companies can pay dividends regularly, making them suitable for investors seeking passive income from their portfolios.

Support from Government Policies The energy sector is prioritized through plans like PDP (Power Development Plan) and AEDP (Alternative Energy Development Plan), which set long-term electricity generation targets.

Shift Toward Clean Energy The world is moving toward green energy, and companies investing in renewable sources have growth opportunities aligned with ESG principles increasingly valued by institutional investors.

Basic Understanding of Power Business and Revenue Structure

Before investing in power stocks, it’s important to understand the fundamentals:

Power Purchase Agreements (PPAs) Power companies typically sign PPAs with government agencies, usually lasting 10 to 25+ years. These contracts specify electricity prices and quantities, making revenue streams predictable.

Classification by Capacity Power companies are generally categorized as:

• IPP (Independent Power Producer) – capacity over 90 MW
• SPP (Small Power Producer) – capacity between 10-90 MW
• VSPP (Very Small Power Producer) – capacity less than 10 MW

Types of Energy Power plants utilize various fuel sources such as:

• Solar energy – increasing in popularity as a green energy source
• Hydropower – stable and clean
• Natural Gas – cleaner than other fossil fuels
• Renewables – wind, biomass, tidal energy
