When the NEM’s Largest Generating Unit Trips …

A follow-on to my earlier article of a couple weeks ago, looking at another instance where a team effort was required to counter a drop in system frequency following the loss of generation at a large power station (this time the single unit Kogan Creek power station – the largest single unit in the NEM).




Short term forecasting of wind power plant generation for the provision of ancillary services

As NEM wind power plants progressively work towards implementing FCAS, the criticality of ensuring that the power system either a) takes account of the variability in the wind forecasts coming from the wind power plants in the coming 5-7 minutes and follows the wind direction, or b) sets an appropriate dispatch level to ensure wind variability is minimized, becomes even more important for market and power system operators.



Grandfathers Axe or Low Hanging Fruit?

Upgrading our existing coal thermal fleet to increase efficiency and flexibility could provide a cost-effective opportunity to add dispatchable capacity and lower the overall carbon intensity of our electricity sector.

Cost Confusion

Our guest author, Allan O’Neil, posts an overview of the strengths and weaknesses of an increasingly popular metric – the LCOE (or Levellised Cost of Energy)


Energy Supply Disruption – Understand the Customer Drivers

The energy supply industry is now a case study of major disruption and this is causing chaos. We are now witnessing the simultaneous high prices in electricity and gas – importantly at the commodity level – not network driven this time – although that just changed with the AER loss – more petrol on the fire.
