EGAT (Electricity Generating Authority of Thailand)
EGAT is Thailand's state-owned electricity system operator under Ministry of Energy. Three roles: (1) own-generation across Mae Moh lignite, Bang Pakong gas, EGAT hydro (~15-20 GW installed); (2) national transmission network monopoly; (3) single-buyer commercial counterparty for all IPP, SPP PPAs (~35 GW off-take). Under Energy Industry Act B.E. 2550 EGAT implements PDP2024 power-development plan, operates system dispatch. Not listed; consolidated into Thai state accounts.

What this organisation actually does
EGAT owns, operates Thailand's high-voltage transmission network, dispatch centre. Own generation includes Mae Moh lignite complex (~2.4 GW, largest Thai thermal plant, phased retirement under PDP2024), Bang Pakong, South Bangkok gas-fired plants, EGAT hydro (Sirikit, Srinagarind, Rajjaprabha, Pak Mun etc.), and selected smaller plants. Commercial counterparty for all IPP (~25-year PPAs at ~90% capacity factor), SPP (cogeneration), VSPP (renewable) off-take.[]
Strategic role: implements PDP2024 policy (50%+ renewables by 2037, coal phase-down, LNG expansion) via capacity auctions, Mae Moh retirement, transmission investment. System-reliability, cost-containment operator. Not tradable but materially shapes tariff, PPA pricing, renewable-auction pace.[, ]
Programs administered
Generation
Own generation β ~15-20 GW
Mae Moh lignite complex (~2.4 GW; PDP2024 phased retirement), Bang Pakong, South Bangkok gas-fired plants, hydro portfolio (Sirikit, Srinagarind, Rajjaprabha, Pak Mun). State-owned; costs pass through tariff, not market-priced.
Transmission
National grid monopoly
High-voltage transmission network, national dispatch centre. Grid reliability operator. Wheeling fee structure; capital investment in grid modernisation, smart-meter, renewables interconnection under PDP2024.
Off-take
Single-buyer PPA β ~35 GW IPP, SPP, VSPP
Commercial counterparty for all independent power producer PPAs (~25-year, ~90% capacity-factor), SPP cogeneration, VSPP renewable feed-in. PPA terms, capacity payments, energy payments shape listed IPP earnings (GULF, GPSC, RATCH, BGRIM).
Policy
PDP2024 implementation
Implements 2024 Power Development Plan: 50%+ renewables by 2037, coal phase-down, LNG expansion, grid stability. Renewable capacity auctions and auction pace directly affect listed IPP pipeline.
Watchpoints
Mae Moh retirement schedule
Largest Thai thermal plant; PDP2024 phase-down timing.
Renewable auction pace
Translation of PDP2024 targets to IPP/SPP/VSPP awards.
Transmission investment
