City moves closer to trigen

Council agreed on Monday to begin final negotiations with energy provider Cogent Energy to build and operate a ground-breaking, low-carbon, trigeneration energy network to power central Sydney and slash greenhouse gas emissions

Trigeneration runs on natural gas and produces low carbon electricity, heating and air-conditioning for clusters of surrounding buildings. It is nearly three times more energy efficient than coal-fired power stations and can reduce greenhouse gas emissions by 40 to 60 per cent compared to coal-fired power.

Our aim is to take most, if not all, of city buildings off the coal fired grid as part of our 2030 goal to cut carbon emissions by 70 per cent.

Stand alone trigeneration plants are already being used by a number of companies in Sydney including GPT Group, Stockland, Investa and Westfield. However, the City's plan goes much further, with trigeneration networks to supply precincts or clusters of buildings similar to Europe, the USA and Asia.

The package we are now negotiating with Cogent Energy includes not only City of Sydney council buildings, but the first of four "low-carbon-zones" across central Sydney, as set out in the City's Trigeneration Master Plan:

  • CBD North (Martin Place/George Street)
  • CBD South (Town Hall Precinct)
  • Pyrmont/Ultimo and
  • Green Square.

A study by the University of Technology Sydney estimates this project could save up to $1.5 billion in avoided capital investment in new coal-fired power stations and grid upgrades.
