On Saturday 25th August 2018, the NEM experienced what has been called by others a “near miss” event, with both Queensland and South Australia being islanded from the rest of the NEM as a result of the tripping of QNI and Heywood interconnectors (respectively). I saw this happened on the day, so had time to…
Over the prior week (Monday 4th June to Friday 8th June 2018), the NSW region – and, to a lesser extent, the broader NEM – experienced a tight supply/demand balance. In response to what was happening during the week, we saw a range of activity ourselves, including: (1) One-on-one questions with clients Our prime focus…
In his article “Rush to renewables as coal cools” in the Australian on Thursday 7th September, Andrew White used a reproduction of the RenewEconomy-sponsored NEM-Watch Fuel Type Widget to help his readers understand the fuel mix that was occurring for one 5-minute period (the 16:30 “dispatch interval”) the previous day. The widget also has been…
Monday 31st July 2017 was a day (one of an increasing number in recent years) when dispatch prices for energy in South Australia dropped below $0/MWh – and, in this case, down to the Market Floor of -$1,000/MWh for the 13:30 dispatch interval. We posted two images from NEM-Watch v10 on WattClarity here, to help…
On Thursday 6th July 2017, I posted this analysis on WattClarity ® about some “off the chart” movements in average prices, and pricing patterns, across all 5 regions of the NEM – but most pronounced in VIC, TAS and SA. This analysis was performed using NEMreview v6. Following from this, we saw the analysis referenced…
On Friday 30th June 2017, I posted this analysis on WattClarity ® about the low levels of aggregate wind production seen across the NEM through June 2017. Matt Chambers, resources reporter at The Australian picked up this article and added additional comments in his article “Lack of wind blows out South Australia power costs” on…
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…
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….
The electricity supply industry is currently the subject of much conjecture about how the future might unfold. One such scenario involves the possibility that the cost of solar and storage will continue past patterns of decline to the point where the cost of each becomes negligible. Software industry veteran Mike Cannon Brooks commented on this…
Our new internationally-focused LiveGenTM widget has been live for a short period of time, and can be accessed here: http://data.RenewEconomy.com/LiveGen We’re pleased to be able to work with the people at RenewEconomy to help make global complexity more understandable – in this case, in terms of the contributions of various generation fuel types across a…
