Transforming the way Australia produces and uses energy must be a cornerstone of a national response to addressing greenhouse gas emissions. Natural gas can deliver significant greenhouse gas emission reductions at a fraction of the cost of alternative technologies. To drive this forward, industry is looking for policy certainty and a level playing field. Furthermore, there exists the opportunity to leverage other low emission technologies from gas—for example, the integration of natural gas combined cycle generation with a solar thermal array offers an opportunity to enable the early deployment of solar thermal technology in Australia. Integration can deliver a power outcome at lower cost and with higher conversion efficiencies than an equivalent stand-alone solar thermal facility.

Technical and economic metrics of electricity generation from a Waste to Energy (WTE) plant are compared to coal, natural gas combined cycle, biomass, and landfill gas generation alternatives for Austin, Texas under a range of greenhouse gas emissions prices. The WTE technology and history is described, as well as details relevant to a WTE plant in Austin. Technical and economic values for WTE from the literature are discussed. The upper limit of electricity generation from Austin’s MSW stream is 5% of Austin’s 2007 annual electricity consumption. Selection of appropriate values for capital, operating, and fuel costs indicates that WTE is more expensive than all of the alternative generation technologies considered (coal, natural gas combined cycle, landfill gas, and biomass). If greenhouse gas emissions are priced and offsets from fugitive landfill gas emissions are allowed, WTE becomes more cost-competitive by taking credit for offset landfill gas emissions. Under this scenario WTE becomes cost-competitive with biomass at $33 per ton CO2 equivalent, coal at $92 per ton CO2 equivalent, and natural gas at $115 per ton CO2 equivalent.
