Collections of events that we see happening in the NEM, categorised in terms of the seasons in which they occur.
Through the week we’ve seen new highs for wind production (NEM-wide) and also some low levels of production, as well – mirroring the political debate. The challenge has serious implications, however, and the AEMO sessions mentioned might be one way to learn more.
Following today’s announcement of the closure of Alinta’s Northern Power Station in South Australia
Some quick notes Tuesday evening about liquid-fuelled peaking generators getting a run in a South Australian region that’s missing Northern station (amongst other factors)
A quick look at how the Nyngan solar plant stepped up its output over the weekend, reaching full load.
A quick look at how the early winter chills are driving demand in Tasmania to levels not seen for 4 years
Windy conditions persist – and bring with them their own challenges for the AEMO in managing the security of the system
(PS wind contributes to, but there are other factors discussed in the post)
Looks like wind output, aggregated across the NEM, hit a new record in output overnight.
Royalla solar farm (opened 6 months ago) now has metered generation data published by AEMO – here’s the first view.
Completing our walk-around-the-NEM, today we look at peak demand in Queensland over summer 2014-15
Continuing the theme of investigating peak metrics over summer 2014-15, today we look at peak wind output (aggregate across the NEM).
One of our guest authors, a meteorologist, lends his expertise to helping us understand one of the reasons why peak demand for summer 2014-15 was what it was.
Today we have a look at what mark Tasmania reached with peak demand over “extended summer” 2014-15
Continuing the theme started last week, today we look at what the peak NEM-wide demand was for “extended summer” 2014-15.
Continuing our walk around the NEM, today we analyse what happened with South Australian electricity demand over the extended summer period 2014-15 – with a particular focus on peak demand
Following our assessment of NEM-wide demand this summer, we turn our attention to Victoria today to see how similar the story is for that region in particular.
Quick notes about three types of solar PV systems, at University of Queensland’s Gatton Solar Research Facility.
Some analysis of what happened with NEM-wide demand this summer
The Nyngan large-scale solar PV plant started production in March – but, as shown here, large-scale solar has a lot of catching up to do to match current levels of small-scale solar PV production.
Some back-of-the-envelope calculations being a starting point to help me understand how much real contribution electric vehicles might make in feeding back into the grid when intermittent generation is absent.
Some initial analysis of the interplay between wind and solar in Australia’s National Electricity Market
