42 months after I posted some initial thoughts about “the opacity of rooftop PV” it seems that – when viewed in certain ways, discussed here – the problem is actually getting worse, not better.
Rapidly growing solar PV output has been widely tagged as the cause of low and even negative prices in Queensland. But in any market it’s the behaviour of ALL participants that determines price outcomes. Guest author Allan O’Neil takes a closer look at recent NEM bidding.
A synopsis of the presentation provided by guest author, Jonathon Dyson, at the Solar Asset Management conference earlier today in Sydney.
A quick article highlighting how the trend in aggregate number of unit starts, across the whole of the NEM, highlights the scale of one of the core underlying changes (and challenges) facing us in the NEM’s energy transition.
Guest author, Tristan Edis, takes a look at the changing pattern of generation by fuel type in 2018
A quick look at the effect that the monsoonal rains in northern Queensland are having on several power generation options in northern Queensland.
Replacement of yet another blown LED at home on the weekend prompted me to dive into some historical voltage readings (made accessible through our Solar Analytics subscription). I present some results here, and hope some knowledgeable readers can help me out with 4 Questions I pose…
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
The start of some analysis that helps to identify the variety of factors that combined to give a shaky balance between supply and demand in NSW last week.
Already we are seeing the highly correlated output of solar PV deliver interesting challenges for the NEM – both to the project proponents themselves, and also to the “everything else” that supplies what’s left of the underlying demand from electricity from any source.
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.
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.
Afternoon demand on Christmas Day as low as overnight demand as a result of several factors
With Genex releasing an ASX announcement of first revenue at Kidston Solar Farm, we use NEMreview v7 to have a quick look.
Following on from my earlier post about my own experiences as a small power generator (with solar PV at home), I’ve taken a broader look at solar PV production NEM-wide, including over the corresponding “stormy weather” period of October highlighted in the prior article.
There’s already been a large uptake of distributed energy generation data, and there promises to be much more to come in this energy transition. With this comes some significant challenges – along with opportunities (with respect to the electricity production itself, and also in terms of the data that’s produced). So in the interest of doing things better, here’s a detailed look at our own rooftop solar experiences at home.
Following Wednesday’s article by Paul McArdle on WattClarity, we’ve reviewed the (very cloudy) weather patterns for Friday 19th May 2017, and the accuracy of Solcast’s predictions of a day of low solar PV output
Some thoughts about challenges with intermittent solar PV, triggered by this week’s Solar Eclipse in North America
The recent demise of start-up retailer, Urth Energy (suspended from the market by the AEMO on 1st February) was an unfortunate development on this path of the energy transition.
