Fast Frequency Service – Treating the symptom not the cause?

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.


Let’s talk about FCAS

Ancillary Services Matter! No longer just realm of electrical engineer or energy trading boffins, ancillary services (and particularly Frequency Control Ancillary Services or FCAS which will concentrate on today) have become front and centre in so many ways that barely a day goes by without market observers referring to grid stability, inertia or frequency management.


Where is the east coast domgas development boom?

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.




How tight demand/supply situations can make solar forecasting important

NSW demand rose to a near-record high on Friday the 10th of February, and QLD soared to a new record demand on that Sunday, amidst an intense heatwave. While this heat-stressed our electricity markets and infrastructure, the nation’s rooftop solar PV systems were providing critical load reduction under plentiful sunshine.


Five fixes for the NEM

Load shedding in South Australia on Wednesday 8 February and successive ‘close shaves’ in NSW and Queensland as the heatwave spread north have exposed serious weaknesses in the national electricity market (NEM).












Review of the NEM in 2016

Electricity consumption in the National Electricity Market (NEM) increased by 0.8% in 2016, this is on top of a 1.1% increase in 2015. Queensland and NSW experienced increases in consumption with all other states experiencing a reduction.



The new energy ecosystem

Transformation in the electricity industry is occurring at an astounding rate. What’s more, it’s happening globally and Australia is pretty much ground zero. As a result, a new energy ecosystem is emerging. Accenture has recently released three reports which cover different aspects of this new ecosystem. These are the ‘New Energy Consumer’ report, ‘Digitally Enabled Grid’ report and the combined report for the ENA and CSIRO titled ‘Insights from Global Jurisdictions and Evolving Business Models’.
