Mr.TepsakTitaraksa, Assistant Governor of the Metropolitan Electricity Authority (MEA), recently presided over the launch of the Chidlom outgoing tunnel excavation, which, with a diameter of 3.6 metres, will be the largest power transmission tunnel in Thailand. This latest project will extend the system from Chidlom Road to Sarasin Road (beneath the road system) and Ploenchit Road (betweenChidlomand Ploenchit Intersections). The tunnel will be 3.6 meters in diameter at a depth ofaround 40 meters and approximately 1,300 meters in length, making it the largest power transmission tunnel in Thailand. It will also improve the reliability of the power transmission system and reduce the risk of physical damage to conventional above-ground power lines as a result of accidents and storms. The overall 230-kV underground power transmission project is divided into four parts including those that have been completed, comprising the tunnel project between the Bang Kapi and Chidlomterminal power transmission stations covering a distance of 7 km and the Lad Phrao - Vibhavadi power transmission tunnel, and those currently under construction, including the Prakanong Canal project and the outgoing tunnel at Chidlomterminal station.
