Conventional Power Plants
Aside from focusing on enterprise value creation,
RATCH also fully participates in securing
the national power grid stability
by concerning that it is a crucial infrastructure for economic and social development of the country. Therefore, the Company mostly interests in fossil fuel power projects due to its reliability and availability enabling to timely and consistently serve power demand at all circumstances.
To minimize fuel risk, RATCH also considers diversification of power plants fired with different fuel such as natural gas, coal and fuel oil. This helps strengthen our business growth and stabilize the national electricity system in Thailand and invested countries.
