We’re taking a much, much deeper dive into generator performance at high temperatures (for all DUIDs operational across the NEM) to see how each one of them, individually, is affected by high temperatures. Guess which one this “mystery DUID” is and we’d look forward to providing some form of prize…Read More
Despite growing diversity of Large Solar farms (NEM-wide), large weather events still have major dampening effects
Sharing a trend of daily capacity factor across all Large Solar plant (post commissioning) in the NEM (preliminary analysis for our Generator Report Card).
With another upsurge in interest in the effect of Hazelwood closure on price outcomes in the NEM, we’ve invested some time to provide these thoughts.
Guest author, Drew Donnelly, compares case studies of Argentine and Australia to highlight risks in under and over-investment in network infrastructure
A note of caution, that Demand Response is not a magic wand – it *can* achieve a lot, but if can’t be assumed to automatically appear to bridge any gap between supply and demand in a market model, for instance.
One more example of not focusing on the real problems seems to be a tendency for some to obsess about one narrow type of Demand Response (i.e. dispatch of NegaWatts) whilst seeming to lose focus of what the overall objective is (a more active and responsive demand side).
Now that summer 2018-19 has passed, we can reflect on our experiences as a new entrant energy services company facilitating spot exposure for residential energy users – and hence expanding the scope for Demand Response in the NEM.
Some thoughts (triggered by the latest wave of focus on “cost” on social media this week) about why we need to rapidly shift our focus to what customers “value” and the market needs.
The growth of Large Solar in the NEM has been phenomenal, and a sign that things are changing quickly in the Australian energy industry. The chart attached is the maximum…
We’ve noted what seems to be an increasing tendency of all of us to reach for some form of “magic wand” as a cure-all for the vexed challenges confronting us in this energy transition.
Recently there have been a number of media reports of energy industry people talking about too much solar. One of our guest authors takes a look.
Fifteen months after first speaking at Clean Energy Summit about the train wreck that’s ongoing in terms of our mismanaged energy transition (and coincident with another industry gathering in the form of the AFR National Energy Summit), we note about Villain no5 as the next contributor to our transition running off the rails…
Through our consulting business, Greenview Strategic Consulting, we have had the pleasure of working with a variety of new entrants and NEM-veteran organisations alike in the generation sector of the…
A year after I first spoke about “Villains” playing a role in the train wreck of our energy transition, I’ve finally found some time to post about Villain #4.
Some further thoughts on what we’ve termed a “Solar Correlation Penalty” which point-view of some specific dispatch intervals seems to suggest is occurring
Our guest author, Dave Guiver from ERM Power, outlines some new options for hedging in relation to the influx of many new large-scale solar PV projects
An advertisement seen on TV in recent days from a (relatively) new entrant in the energy sector reinforces, to me, the need for the energy sector more broadly to do a much better job of respecting its prospective customers.
The East Coast power system of Australia has the worst frequency regulation in the developed world. This puts the system at risk whenever an event occurs which requires the generators to respond quickly – they can’t respond quickly if they have to wait for the system frequency to go outside its control system dead band.
As NEM wind power plants progressively work towards implementing FCAS, the criticality of ensuring that the power system either a) takes account of the variability in the wind forecasts coming from the wind power plants in the coming 5-7 minutes and follows the wind direction, or b) sets an appropriate dispatch level to ensure wind variability is minimized, becomes even more important for market and power system operators.
Following on from the Let’s Talk About FCAS post, the focus of this post is the business case and subsequent optimisation challenge for getting involved in FCAS, now that the technical performance components have been mostly addressed.
