The wholesale cost of electricity has risen (too fast, too high) in recent years. However let’s not let ourselves be conned into believing that this has arisen, now, because of the creation of the NEM back in 1998.
The National Electricity Market (NEM) is designed to operate at 50 Hz. Frequency deviation occurs when generation and load are mismatched. It is important in a lightly meshed and long network such as the NEM to maintain tight frequency control and that frequency response is available throughout the network.
When markets operate normally, a sharp rise in the price of any commodity triggers a boom in exploration, development and new supply. But this is not seeming to happen in response to high domestic gas prices. In this article, guest author (Graeme Bethune) examines why.
