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.

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.

Perhaps unrealised by many, but Tuesday afternoon’s events in Victoria resulted in a new record low in terms of number of coal units being online in the region, Geoff Eldridge explores.
A major blackout left 500,000 Victorian homes without power – but it shows our energy system is resilient
Dr Roger Dargaville from the Monash Energy Institute argues that Tuesday’s events in Victoria were a showing of a system resilience, and not fragility.

Summer 2023-24 demand – high or low?
Inspired (or provoked) by Paul’s earlier article noting ‘NEM-wide demand has been quite low through summer 2023-24 (at least to date)’, guest author Allan O’Neil takes a look at how aggregate consumption stacks up for this summer, compared to prior.
Policy implications now and for the transition
