The Metropolitan Electricity Authority (MEA), along with the cable installation operator and the National Broadcasting and Telecommunications Commission (NBTC), conducted a site survey to assess dismantling of old power cables along Naradhiwas Rajanagarindra Road, as the concluding part of the Conversion of Overhead Cables to Underground Project in Nontri. The Nontri Project covers 8.3 kilometres comprising seven routes, namely, Sathu Pradit Road, Soi Anuman Rajdhon, Sawang Arom Road, Ratchadapisek (Chalerm Mahanakorn Motorway), Sathon Road, Nang Linchi Road, and Naradhiwas Rajanagarindra Road.
The cable dismantling along Naradhiwas Rajanagarindra Road began on 5 May 2022, following completion of pipeline construction for underground cabling and agreement on cable installation services. The old cables are now being removed and the underground system is taking over, leaving only demolishing of the old poles and cables to complete the project. The conversion to underground cabling aims to build stability and reliability in the electricity system while supporting rising electricity demand from business and private sectors. The project also helps promote Bangkok’s Smart City scenario and increases safety for residents.
MEA has so far laid 215.6 kilometers and the project is slated for completion in 2025. The completed projects comprise 62 kilometres of underground power cabling covering the Nontri Project and parts of Silom Road, Sukhumvit Road, Phaholyothin Road, Phaya Thai Road, Rama I Road, Ratchadamri Road, Ratchawithi Road, Ratchaprarop Road, Si Ayutthaya Road, Sawankhalok Road, Sathu Pradit Road and Sawang Arom Road.
Ongoing works stretching 153.6 kilometres include Rama III Project, Ratchadapisek Project, and the ASEAN Metropolitan Project being undertaken alongside BTS skytrain extension lines. Construction is planned to mitigate inconvenience to businesses and residents in the affected areas.
