Based on some preliminary analysis of the Powerlink’s ‘Qdata’ set (available in ez2view) we present our current hypothesis as to the sequence of the events yesterday in the QLD region, where 600MW of solar generation was lost, causing the price to spike to MPC.
Considerations on how key aspects of the upcoming wholesale mechanism might dictate how much response capability will be realised once the mechanism goes live before Summer 2021-22
Alerted to a price spike at 09:45 this morning in the QLD region, we discovered some reduction in load (spot-exposed Demand Response probably) and also a large collective trip in Solar Farm output (reasons unclear).
A couple glimmers of hope spotted recently, that there might be some (belated) awareness that the current methods of support for ‘anytime/anywhere energy’ are not scalable, or sustainable.
Records continue to tumble in the off-season, with the rise of rooftop PV. Both South Australia and Whole-of-NEM hit new low points Sun 11th October 2020.
Ben Skinner from the Australian Energy Council examines how transmission is currently funded in the NEM.
Only 52 days after I initially envisaged being able to have this article published, a couple things today have prompted me to post this drain-dump of concerns that have been jangling around in my head – related to possible risks that COVID might pose in the NEM.
This 20th Case Study (the other side of the weekend to the 19th Case Study) in the series investigates one dispatch interval showing extreme Aggregate Under-Performance across all Semi-Scheduled units on Monday 8th April 2019.
Following the consultation process conducted by the AER (stemming from their Issues Paper 3 months ago) the AER has today submitted a rule change request to the AEMC relating to Semi-Scheduled generation.
This 19th Case Study in the series investigates one dispatch interval showing extreme Aggregate Under-Performance across all Semi-Scheduled units on Friday 5th April 2019.
A month on from the prior low point seen for Scheduled Demand (and Operational Demand) across Queensland in the middle of the day, the low point mark is driven lower still on Sunday 27th September 2020.
University of Queensland PhD candidate, Nicole Lashmar, is conducting a research project which aims to identify the motivations, risks and opportunities for businesses when deciding to participate in demand response programs.
This 18th Case Study in the series investigates two separate dispatch intervals showing extreme collective under-performance across all Semi-Scheduled units on Monday 25th March 2019.
A short article today, highlighting the release of this Amperon report for AEMO looking at the way in which the performance of some Large Solar Farms in the NEM were affected by bushfire smoke through summer 2019-20.
Short note to follow presentation by Marcelle Gannon and Jonathon Dyson on Thursday 17th Sept 2020 to an audience organised by Clean Energy Council (CEC).
A short article providing access to the much-talked-about report.
Hot on the heels of a new record low point for Scheduled Demand (a week ago) in VIC, today sees Scheduled Demand in SA plunge to 315MW in the 11:50 dispatch interval on Sunday 13th September 2020.
A quick look at this dispatch interval – as the 17th Case Study in the series looking at extreme results for Aggregate Raw Off-Target for all Semi-Scheduled DUIDs.
