## What Is Net Metering and Why It Matters for Thailand’s Businesses
Net metering is a solar energy policy that allows businesses and homeowners to feed excess solar electricity back into the grid and receive credits for the energy they export. For factory and commercial building owners in Thailand, this policy can significantly enhance the financial viability of rooftop solar investments by:
– Maximizing solar self-consumption
– Reducing reliance on grid electricity
– Creating additional revenue streams from excess generation
– Providing long-term electricity cost stability
## Thailand’s Net Metering Policy Evolution (2024-2026)
### Key Policy Milestones
– **2024:** Thai government introduced enhanced net metering regulations under PDP2024
– **2025:** Increased system size limits for commercial installations
– **2026:** New incentives for industrial net metering projects
### Current Status (2026)
The Thai government remains committed to expanding solar energy through net metering, with specific focus on industrial and commercial sectors.
## How Net Metering Works in Thailand (2026)
### Basic Principle
Your solar system generates electricity during the day. When your consumption exceeds solar production, you draw from the grid. When solar production exceeds consumption, excess electricity flows back to the grid and you receive credits.
### Billing Mechanism
– **Solar Credits:** Calculated based on the electricity export rate
– **Credit Valid Period:** Credits are valid for 12 months from the month of generation
– **Carry Over:** Unused credits can be carried over to subsequent months within the validity period
### Example Scenario
| Month | Solar Generation | Factory Consumption | Net Export | Credits Earned |
|——-|——————|——————–|————|—————-|
| Jan | 800 kWh | 600 kWh | 200 kWh | THB 800 |
| Feb | 750 kWh | 900 kWh | -150 kWh | THB -600 |
| Mar | 850 kWh | 700 kWh | 150 kWh | THB 600 |
| **Q1 Total** | **2,400 kWh** | **2,200 kWh** | **200 kWh** | **THB 800** |
*Note: Export rate used in this example is THB 4.00 per kWh (subject to change)*
