Colongra Gas Transmission & Storage Pipeline

The Colongra Gas Transmission and Storage Pipeline was designed and built by Jemena to deliver gas to Snowy Hydro Limited's 667MW gas turbine facility near the existing Munmorah power station on the Central Coast of NSW. The pipeline not only transports gas to the power station but also stores enough gas to allow the power station to run at full capacity for five hours.

The Colongra pipeline includes 3.5 kilometres of 10 inch feeder pipeline, a 42 inch storage pipeline, a compressor station that increases gas pressure from 3.4MPa to 13MPa and a let-down station. It is the largest on-shore gas pipeline in Australia and is double looped to create nine kilometres of pipeline storage in a three kilometre stretch of land.

We look forward to discussing your gas transportation requirements.
