The Electricity Generating Authority of Thailand (Egat) plans to build a new THB20bn ($485m) gas-fired power unit at its existing North Bangkok plant this year to help meet growing demand.

The plant will address a predicted shortfall in power supplies from the delay of two gas-fired power plants in Chachoengsao province, according to the Bangkok Post.

Egat governor Sutat Patmasiriwat told the Bangkok Post that work on the 800MW facility could start next year for operation from 2015.

“If no new capacity enters the power grid at that time, total power output reserves will be about 9% of total capacity, below global reserve standards of 15%,” Patmasiriwat said.

“To ensure power security, Egat has decided to move up construction of the second North Bangkok unit by two years to offset the delayed plants.”
