Generators used to consider the Australian National Electricity Market (NEM) FCAS causers pays factors (CPF), used to allocate FCAS regulation costs across the market, as an obscure and unimportant technically challenging curiosity. Since 2014,...
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...
Some quick thoughts about Tesla's promise to "fix South Australia's power woes". Which specific problem is Tesla promising to fix?
Because of (technical and commercial) interconnectedness in the National Electricity Market, the possibility of unintended consequences should be kept in mind
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...
The three main flaws that put boundaries on the usefulness of all forecasting/modelling
Can you help me understand this apparent (and large) disconnect between words and actions in the GreenPower space?
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...
Some thoughts about the possible uplift to Infigen Energy revenues, stemming from higher forward contract prices in the South Australian region of the NEM
In today’s energy sector, it is rare to get electricity networks, retailers, generators and system controllers in the same room at the same time. In a deconstructed market about to be transformed by distributed...
A starting list of factors that I'd look further into, if I was sucked into the "rabbit hole" of assessing all of the contributing factors leading to the Remarkable Prices seen in Q2 2016...
Some initial analysis about the remarkable pricing outcomes seen across all regions of the NEM through Q2 2016
Over on our Demand-Response focused site, I posted an article yesterday providing a high-level comparison between contract prices for calendar 2015 and final spot prices (for the 4 mainland regions). This was in response...
Our guest author, Mike Williams, has posted some analysis (over on the specially-focused Demand Response site) looking at the benefits of spot exposure and Demand Response in Queensland
Back on 8th October, I spoke at All Energy in Melbourne on this topic. Given the questions posed after the session, it seemed that it might be of value to some WattClarity readers if...
A quick look at how ramp rates would vary (for "Unserved Consumption") in the hypothetical "10x" high intermittency grid.
Continuing our analysis of these hypothetical future scenarios to understand the shape of "unserved energy" and hence the potential contribution of Demand Response - today I post about energy spilled in a future with...
Laying out the framework for the analysis I'm doing for my presentation at All Energy 2015 - about the role Demand Response might play in a future market dominated by intermittent generation
Sitting on the outside, looking in, this article sums up what seems to be the main areas of contention in the great Network Debate that's been running the past couple years.
The University of Queensland has called for applicants for the next round of the E.S.Cornwall Memorial scholarship (closes Friday 31st July). A great opportunity for a young engineer to gain international experience at this...
