This started as a consideration of how applicable ‘change of electricity demand’ is as a general metric for communicating the impact of coronavirus (and measures taken to address it). However it is morphed into some considerations much broader than the energy sector…
Guest author, Allan O’Neil tries to piece together further detail of what is intended with the apparent tightening of the Reliability Standard (which has sat at 0.002% USE for many years).
Like everyone else, we’re grappling with how COVID-19 will impact on us personally – and also in terms of what we do at work. Here’s a few initial thoughts about the types of impacts (and risks to manage) in relation to the National Electricity Market.
An article published by AEMC on the ‘value of dispatchability’ provided the spur to return to our intention of freely sharing insights gleaned from the Generator Statistical Digest 2019. Today’s article highlighting the value of dispatchability.
Alarms in one of our NEMwatch dashboards alerted me to the plunging level of Scheduled Demand seen this afternoon in the the Victorian and South Australian regions of the NEM – a new record low point for South Australia.
Last week saw more in a growing series of exits, and asset write-downs, amongst new entrants in the supply of renewable energy within the NEM. Today on WattClarity I ponder whether we have been setting them up to fail due to the nature of support provided to these new entrants. What is your perspective?
Another islanding event separated the SA region from the rest of the NEM yesterday (Monday, 2nd of March). Allan O’Neil investigates what happened before the event and possible causes.
As time has permitted, I’ve invested some time to prepare this first stage of a review of what went on during the period from 31st Jan 2020 to 17th Feb 2020 – a period during which the South Australian region formed its own frequency island following the transmission line damage. A period we’ve called an ‘accelerated accidental experiment’.
Two weeks ago (Monday 17th February) a ‘temporary fix’ was put in place to reconnect SA with VIC following the transmission line outage that began on 31st January 2020. Well, we’ve islanded again today….
