Colongra Power Station

In January 2015 Snowy Hydro acquired the largest gas-fired power station in New South Wales, Colongra Power Station.

Opened on 21 December, 2009 by Minister for Energy, The Hon. John Robertson, the 667 MW Colongra plant is based on four flexible and low emission dual fuel gas turbines in open cycle configuration.  Gas turbine generation produces 40% less greenhouse gas emissions than equivalent coal fired generation.  It starts up quickly at short notice to supply electricity during times of high demand.

International engineering firm Alstom designed and built the gas turbine power plant.

Information on the pipeline

The natural gas to fuel the turbines is supplied via a new underground pipeline which connects to the existing Sydney-Newcastle pipeline.   Jemena is the company which constructed and operates the pipeline.  For more information go to Jemena – Colongra pipeline.
