Delta has gained approval to build a gas-fired power facility, and associated infrastructure, in Bamarang, near Nowra. The gas power facility would create electricity from natural gas and help meet future electricity needs in NSW.
Delta Electricity purchased a site off Yalwal Road, Bamarang, approximately 8km southwest of Nowra, for the proposed development. The central portion of the site was previously cleared and developed as an abattoir, although the facility was never operated.
The proposed site and transmission corridors (for gas supply and to deliver electricity) are shown on the map below. The gas supply pipeline will run underground and will connect the facility to the main Eastern Gas Pipeline. The electricity transmission line will run above ground along the existing cleared transmission corridor through the Bamarang Nature Reserve to Flat Rock Creek. From there, it will run underground through the urban area and connect to the existing main substation, near the corner of Yalwal Road and Albatross Road.

Development of an open cycle ‘peaking’ facility to meet peak electricity demands
- Installation of two open cycle gas turbines
- Operation during peak demand periods (for example, on hot summer days)
- Operation for approximately 50 days a year, for up to 8 hours a day
- Producing approximately 300 megawatts of electricity during periods of peak demand.
Conversion to a combined cycle ‘base load’ power facility, when electricity demands increase, to provide a constant supply of electricity
- Addition of steam generators and steam turbines to increase the amount of electricity produced
- Continuous operation to meet ‘base load’ needs
- Producing up to 400 mega watts of electricity
The incorporation of environmental controls and management systems in the design of the facility would ensure that potential environmental impacts are minimised during both stages.
In a typical combined cycle facility, electricity is generated by combining the energy from two power generating machines (in this case, a gas turbine and a steam turbine). Natural gas is burned in a gas turbine that turns an electricity generator. The hot exhaust gas from the gas turbine is used to produce steam, which turns a steam turbine and another electricity generator. This increases the amount of energy recovered from the gas, and the efficiency of the facility.
