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.
To clarify a quotation today in the Fairfax media about solar PV performance on heatwave Friday in NSW.
Looking at 13th, 14th and 15th January and the contribution of solar PV to peak demand reduction
NEM-wide demand roared to life today, for the first time this summer, with hot weather pretty much everywhere.
Hot weather drives Queensland demand higher than 9,000MW for the first time this summer – even with many people still out on holidays…
Demand rose in NSW today off the back of some hot weather
New Years Eve and New Years Day have provided 2 excellent examples of the “Duck Curve” in South Australia
A quick look at first output of Barcaldine Solar Farm – as a segue into consideration of what we see as an “audacious” 50% by 2030 ambition.
The three main flaws that put boundaries on the usefulness of all forecasting/modelling
