BACKGROUND North Bangkok Power Plant is the first modern thermal power plant in Thailand. The history of the power plant dates back to the origin of the Electricity Generating Authority of Thailand (EGAT). At the time of the construction of Bhumibol Dam or Yanhee Dam, Yanhee Electricity Authority (YEA) was established to supervise the dam construction and the dam management after the construction was completed. During the dam construction, Yanhee Steam Turbine Power Plant alternatively known as North Bangkok Power Plant was constructed by YEA in 1959 to cope with electricity demand, and it was officially opened on May 17, 1961.
The former North Bangkok Power Plant was regarded as â€œthe role modelâ€? of modern power plants in Thailand, which had supplied electricity to Thailand for 40 years. In 2001, the power plant was decommissioned from the system and removed. Later, the present North Bangkok Combined Cycle Power Plant (NBCC) was constructed in the same area to cope with the increasing demand and to stabilize the system reliability. The present North Bangkok Power Plant is a combined cycle power plant fueled by natural gas. Commenced in December 2006, NBCC was officially operated in September 2010. Later, NBCC Block 2 was built in accordance with the National Power Development Plan of 2004-2015 in response to the demand growth. The project was approved by the Cabinet on July 10, 2012, and the commercial operation date was January 15, 2016. 118
