NEM-Review used on the ABC’s 7.30 report to explain how electricity prices have changed over summer

Hugh Saddler from the Australian National University, has used NEM-Review to help explain the state of the electricity market on the ABC’s 7.30 report which was broadcast on the the 13th of February 2017. In the report, several industry experts provide insights on the multi-state energy crisis over the summer that had been developing for several months.

Various media outlets look to Global-Roam for clarity during heat wave

In early February, numerous news websites including the Adelaide Advertiser and the Sydney Morning Herald embedded our NEM-Watch Live Generation Widget (as seen on RenewEconomy) to help explain the generation mix of each state of Australia during the recent heat waves affecting the South Australian and New South Wales electricity network. In addition to the situational awareness that the widget provided, Allan O’Neil made several posts on WattClarity during the week including this initial analysis attempting to explain the root causes of the blackouts experienced in South Australia.

 

About media quote on solar panels being “mostly useless” late in the day

During the national heatwave of February 2016, we fielded many calls from journalists and saw an increasing number of parties use (or embed) a variety of our bite-sized widgets, all focused at making some aspects of complexity more understandable.

One of the conversations I had with a journalist let to being quoted over the weekend saying that solar PV was “mostly useless” late in the day.  Hence, over the weekend I added this note of clarification on WattClarity for those who are interested in more than just soundbites.

Animation on WattClarity helps explain what happened during yesterday’s blackout throughout South Australia

Our CEO, Paul McArdle spent the best part of last night piecing together the animation below in an attempt to understand what went on leading up to and during yesterday’s blackout throughout South Australia. Using ez2view, the animation explains what happened in generation and demand levels in South Australia between 06:00 and 17:00 on Wednesday the 28th of September, 2016.

An initial post and an update on the situation has already been posted on WattClarity, but time permitting, more analysis of what’s happened will be published over the coming days and weeks.

Image of NEM-Watch used to illustrate 7:30 Report story on Basslink outage of 2016

One of our team members was surprised, last night (i.e. Friday 3rd June 2016) to see an old image of an old version of NEM-Watch (from way back in 2007) used to illustrate how Tasmania would normally be interconnected to the mainland by the sub-sea HVDC (high-voltage direct current) link connecting into the Latrobe Valley in Victoria.

Here’s the image that surprised us:

NEM-Watch used to illustrate what normally would be the interconnected nature of Tasmania to the mainland regions of the National Electricity Market

For those interested in the Tasmanian crisis, the ABC story here is worth a watch.

Coincidentally it was also yesterday that I’d published these updated thoughts on WattClarity ® about the magnitude of the cost incurred, in aggregate, by various stakeholders in the Tasmanian region of the NEM as a result of the Basslink outage, now about 6 months old.

 

Energy generator uses WattClarity and ez2view to highlight demand side response in consultation paper for rule change request

The Snowy Hydro Corporation have submitted a rule change request that would see a change to the National Electricity Rules to oblige price sensitive demand greater than 30MW to bid into central dispatch.

An excerpt from this WattClarity article posted in January 2014 was used in the ‘Statement of issue’ section of the consultation paper, including a screenshot taken from ez2view.

What role might Demand Response play in a (possible) future grid featuring high levels of intermittency?

Last week Paul McArdle posted this article to WattClarity after speaking at All-Energy in early October. His presentation (with narration included) from the conference is available here:

Explaining why large energy users are concerned about last week’s machinations in South Australia

A week of unusual occurrences in the South Australian energy space fascinated many onlookers, particularly large energy users.

After fielding a number of calls from large energy users in South Australia who were wanting to know what was going on, our CEO, Paul McArdle wrote this article on WattClarity to explain why they were concerned, to note observations about what happened and to state the possible implications for the future.
