Guest author, Warwick Forster, provides an explanation of some of the common ways that retailers hedge their risk exposure in the National Electricity Market
Some operations at Stanwell Power Station unit 1 in the past couple weeks caught our attention, and are presented as a useful illustration of some concepts related to flexibility of power generators (in this case, coal-fired power).
Guest author Allan O’Neil provides this handy explainer on how generators’ contract positions affect their bidding decisions and can make negative spot prices pay off, at least in the short term. Very useful for those readers not actively involved in wholesale trading in helping to understand why some conspiracy theories might not match reality.
Guest author, Allan O’Neil, contributes to our series of articles explaining how prices are set the the NEM (as part of how dispatch works). In this article, Allan explains some of the details in the AEMO’s “Price Setter” file.
Highlighting the different approaches taken to cost/price based dispatch in an interconnected electricity system (or market).
Walking through 5 (much simplified) “Dispatch Intervals” to illustrate some starting principles of marginal price based dispatch arrangements, such as used in the National Electricity Market
Conversations in the week following my post about “Villain #4” (being the deficit in required Energy Literacy) prompted some analysis relating to Marginal Loss Factors
Following from a steady stream of questions we receive in relation to a range of our products (but in particular with respect to “the RenewEconomy Widget”) we’ve invested some time to put this post together to explain some of what we understand about electricity demand.
Understanding the difference between blackouts, generator trips and intermittent generation and how these events are managed.
[PART 1 of] a post by guest author, Bruce Miller – which was initially posted on LinkedIn as one piece, but which has been broken into two on WattClarity as each part serves different purposes.
A brief explainer of what “Unserved Energy” (or USE) actually means, in the context of the AEMO “Electricity Statement of Opportunities 2017” (ESOO) released this week.
AEMO data for the National Electricity Market shows business consumption of electricity is more than twice that of residential consumption of electricity
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)
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.
