The project’s objective is to construct a pure pumped storage power plant and to
strengthen Thailand’s ability to cope with peak power demand by using the existing Lam
Ta Khong Reservoir as the lower pond and constructing an upper pond with an effective
water storage volume of 9.9 million ㎥, an underground power plant (250 MW x 2), steel
conduits, and tailrace channel, etc., in Nakhon Ratchasima Province in northeastern
Thailand, thereby contributing to the stability of the electric power supply
