20pc growth in Queensland generation capacity since start of NEM
First 52 of 52 paragraphs shown Queensland had recorded a 20 per cent growth in generation capacity since the start of the National Electricity Market (NEM), ACIL Consulting said in a draft Public Benefit Test report on the operation of the State's electricity legislation and regulations.
Great leap forward: The report recorded over the five years to 2000, total installed generating capacity rose by almost 20 per cent. This growth in generation capacity had changed the supply-demand balance in Queensland from one of low reserve to one of excess capacity, where reserve was now seen as more than adequate.
Queensland an exporter of electricity in the NEM. In 1999-2000, 370GWh of electricity was exported from Queensland and this was expected to grow now that the QNI had opened and when a number of low-cost coal fired generators, such as Callide C, Tarong North and Millmerran, begin generation.
Coal still king: Coal was the dominant fuel source for electricity generated in Queensland, accounting for 76 per cent of total generating capacity. The dominance of coal-fired power stations connected to the eastern grid was due to the abundant supplies of low-cost coal in the coastal hinterland from South to North Queensland. Many power stations (for example Callide A, B & C, Collinsville, Tarong, Tarong North and Millmerran) were located adjacent to their coal suppliers to reduce coal transport costs.
Main power stations: The combined capacity of the plants now operating was 8635MW. Plants under construction had total capacity of 2135MW. In addition, cogeneration capacity in Queensland was approximately 456MW at 30 June 2000, principally using bagasse. In addition to these plants, there was significant generating capacity not connected to the grid that supplied consumers in regional and remote areas. Coal-fired power stations accounted for most of the electricity supplied in Queensland, a result of access to low-cost thermal coal resources. Additional power was generated using gas turbines, diesel engines, water turbines, wind turbines, and systems burning biomass (bagasse, woodchips etc). Solar systems using photo-voltaic cells were used mainly in small, remote power systems.
Total existing capacity 8635MW
Total under construction 2125MW
