Thailand Power Grid Interconnection

Thailand has an energy cooperation with neighboring countries in two types :

Energy Exchange (Grid to Grid) Power PurchaseA B

HVACEGAT - EDL

HVDCEGAT - TNB

Energy exchange between two countries through Grid to Grid System

Non - Firm Capacity

EGAT imports power from IPP in neighboring countries with PPA and the power is imported from the IPP project directly.

B gThailand

EGAT imports power from IPP in Lao PDR with PPA and the power is imported from the IPP project directly.

The 230 kV or 500 kV transmission system are the system voltage for power purchase.

Currently, the 500 kV transmission system is initially energized at 230 kV (Na Bong Substation). When other IPP power plants are connected to 500 kV transmission
