What is Power Purchase Agreement (PPA)?

A Power Purchase Agreement (PPA) is a long-term contract where you, as the power producer, sell the electricity you generate from solar to Thailand’s utilities (EGAT, PEA, or MEA) at a fixed, guaranteed price (Feed-in Tariff).

Instead of only saving on electricity bills, a PPA allows your roof or land to become a source of steady income for the next 15–25 years.

🔢 Numbers That Matter

  • Ground-mounted solar (no storage): 2.1679 THB/kWh

  • Ground-mounted solar + battery storage: 2.8331 THB/kWh

  • Rooftop solar (previous schemes): 6.19–6.96 THB/kWh (25-year contracts)

💡 Example: If your system produces 100,000 kWh/month, at 2.1679 THB/kWh, you would earn ~216,790 THB per month in secured revenue.

✅ Benefits of a PPA

  • Steady income → Guaranteed payments from government utilities.

  • Strong ROI → Most systems pay back in 5–8 years, then generate pure profit.

  • No fuel cost → The sun is free, making revenues predictable.

  • Long-term security → Contracts typically last 15–25 years.

  • Sustainability → Support Thailand’s Net Zero 2050 goals while boosting your brand’s green image.
