With summer 2019-20 fast approaching, we’ll use the refresher on the two core components of risk (probability and consequence) to unpick what the real issue is with respect to concerns about overheating electricity supplies this summer, especially in the Victorian region.
A simple refresher on two core components that combine in order to define risk – probability and consequence.
A first (and perhaps only – as this took longer than initially planned) walk through some of the interesting points of what happened yesterday (Sat 16th Nov 2019) when South Australia islanded from the rest of the NEM with the trip of the Heywood interconnector.
There are a number of reasons why we’re completing the analysis we are sharing via WattClarity – here are two big ones.
Third case study in a growing series – on this occasion looking at the (extreme – and possibly excessive?) lengths taken by Tailem Bend Solar Farm to avoid being dispatched at times of negative spot prices in South Australia. This analysis is specifically focused on Wednesday 6th November 2019.
Readers at WattClarity might recall that we have asked the question above a couple of times in recent weeks – and a big thanks to those who responded already! We’re blessed with opportunities at present (have been for a while,…
RepuTex Energy builds on the Generator Report Card 2018 to provide insights into how different weather patterns impact wind production and the implications for system diversity and portfolio risk.
Guest Author, Warwick Forster, looks at designing a combined solar & storage business model for the NEM
Lowest point seen today since the start of the NEM (excluding the SA System Black) for the South Australian region.
Yesterday, Tuesday 29 October 2019, AEMO issued a Market Notice requesting Generator Recall information from participants in the NSW region. This was issued at 15:27 on Tuesday 29 October 2019, and came after numerous Lack of Reserve notices, the first…
Our second Case Study in a recent series, aimed to help us explore ways to continue the pushing the development of ez2view forward, but also shared with readers here on WattClarity. This time about Daydream Solar Farm on Tuesday 3rd September 2019.
Guest Author, Nathan Potter, analyses the challenges and complexities of new generator development in the market and outlines common traps that can be avoided.
A quick look at what would have been a new “lowest ever” point for SA Scheduled Demand today at 12;30 … if the AEMO forecast had held to be valid.
Guest author (and power system control specialist), Kate Summers, looks at what’s changed since she published a paper on frequency control in the NEM back in January 2017.
Better late than never (perhaps?) today I post a few thoughts about the AEMC’s proposed draft rule change for the incorporation of NegaWatts into centralized dispatch.
An email alert from NEMwatch (noting Scheduled Demand under 500MW in South Australia today) distracts us, and prompts us to dig a little deeper at the longer-term trend.
Our guest author Maria Cahill, offers insights and details lessons learnt over the past two years since moving to Melbourne from the UK to set up K2 Management’s Australian office.
Thursday 10th October 2019 presented another day of many negative price events in the QLD region. In this Case Study (prepared for dual purposes) we look at how one particular solar farm operated through this period – Ross River Solar Farm.
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).
