Rayong to Nonthaburi Gas Pipeline is a proposed natural gas pipeline.[1] The pipeline is also known as the Fifth Transmission Project and Fifth Transmission Project - Phase 2, a name that has also been used to describe the Chachoengsao-Nonthaburi Gas Pipeline.


The proposed pipeline would run from Rayong, Thailand to Sai Noi, Nonthaburi to the North Bangkok Power Plant and South Bangkok Power Plant. The exact route appears on p.14 of a September 2016 TRC Corporate presentation on the project.[2]
