Big Battery Revenues in the NEM Presentation from All-Energy 2024
Alex Leemon of Gridcog delivered this presentation about Big Battery Revenues in the NEM at All-Energy in Melbourne last week.
Analysis of the recent destructive supercell storm in Broken Hill
Anthony Cornelius of WeatherWatch shares insights and graphical displays that demonstrate the extent of the supercell storm that toppled seven transmission towers in Broken Hill last week.
Watt scarcity?
Guest author Allan O’Neil examines some recent episodes of price volatility (particularly 30th July to 5th August 2024) and whether they were driven by a shortage of supply, or other factors.
With the benefit of hindsight – or who’d be an auto-bidder?
Following on from earlier articles about price volatility on Tue 30th July 2024 (particularly in South Australia), guest author Allan O’Neil takes a closer look at the operation of battery units in South Australia.
Unusual wind direction to elevate wind power
Ashleigh Madden of Weatherzone reports on some unusual weather activity scheduled to impact QLD, NSW, and SA wind generation – stemming from a high pressure system moving towards the Tasman sea.
Welcome to the Power Station of the Future – But Take Care
Ellise Janetzki posts this overview about operating hybrid plants, following her presentation at the Clean Energy Council’s ALSSSS event in Brisbane earlier this week.
How severe thunderstorms impact energy infrastructure
Ashleigh Madden of WeatherZone explores how thunderstorms damage transmission and whether a trend of these related weather events exists.
We can’t say yet if grid-breaking thunderstorms are getting worse – but we shouldn’t wait to find out
Reflecting on the transmission tower failures in Victoria in February, a group of researchers from the University of Melbourne have put together this summary of what the long-term wind data is showing, and what it means for the power system.
Generation gone with the wind
Ashleigh Madden of WeatherZone reports that a cold front has marched across southern Australia, breaking the week-long wind lull.
Summer reflections
Guest author, Carl Daley from EnergyByte, provides this summary of summer 2024 – covering price volatility, consolidation of the twin peaks dynamic, and BESS performance.
Optimising a highly renewable NEM from scratch, Part 2
In Part 2 of their modelling and analysis project, David Leitch and Paul Bandarian discuss the modelled results of their sharpe ratio-maximised VRE system, including additional considerations regarding transmission.
Missing megawatts and phantom generation
Seven days ago, AEMO notified the market of a Scheduling Error from 24th Jan 2024 to 7th March 2024. A client asked us what it meant – so guest author Allan O’Neil has helped to explore and explain.
Further thoughts (part 2) about the design paper for the implementation of the proposed Capacity Incentive Scheme
Guest author, Ben Skinner, returns with the second instalment on his thoughts about the Design Paper for the Capacity Investment Scheme – with submissions due next Monday 25th March 2024.
Some thoughts (part 1) about the design paper for the implementation of the proposed Capacity Incentive Scheme
This is the first of a two part discussion on the Capacity Investment Scheme (CIS) Implementation Design Paper (The Paper) released on 1 March 2024. This part will cover its broad objectives and implications. The second part will discuss some…
Yesterday’s Record-Breaking Native Demand for Australia’s NEM and Victoria (22nd Feb 2024)
Geoff Eldridge provides a list of some the key records that were broken in the NEM yesterday, thanks particularly to high demand coming from Victoria.
Fires linger in Victoria, Tasmania as heat shifts to NSW
Ben Domensino of WeatherZone provides an update on the bushfire danger in Victoria and Tasmania, whilst temperature forecasts are projected to be elevated in northern NSW.
Four reasons why rooftop solar will grow to dominate the electricity market
Tristan Edis of Green Energy Markets argues how system longevity, battery-coupling, distribution network capability, and increasing capacity will shore up rooftop PV’s position in the market.
Optimising a highly renewable NEM from scratch
David Leitch and Paul Bandarian present and discuss the model they’ve created which uses a maximum Sharpe ratio wind and solar portfolio for the 2025 calendar year, drawing upon data from the AEMO’s 2024 ISP.
Convective downdrafts and high-voltage transmission lines
In light of another transmission tower collapse caused by convective wind gusts, we’ve invited wind loading expert Dr John Holmes to explain this phenomena.
