Cataloguing various pieces of analysis with respect to VRE (variable renewable energy).
Given what's happened for Monday, Tuesday and Wednesday evening this week (and even tighter supply-demand balance forecast for Thursday evening) we take a look at the correlation between low IRPM and low Capacity Factor...
An (initial and) short review of the solid block of high aggregate wind yield over the ~3 day date range (late Tuesday 28th May 2024 to late Friday 31st May 2024) ... and how...
Coincidentally today, David Osmond has posted about 'another challenging week' for VRE NEM-wide (a week beginning Wed 8th May 2024 - the day NSW hit the Cumulative Price Threshold).
Dan Lee takes a deeper dive into network and economic curtailment, and shares some charts and data maps that demonstrate seasonal effects, and the geographic spread of units affected.
Almost 2.5 years since we released GenInsights21, today we're publishing this article that contains a precis of the analysis included as Appendix 27 under the title 'Exploring Wind Diversity'.
Taking a quick look at the dispatch interval through this period of low aggregate wind harvest that also saw lowest aggregate VRE (Wind + Large Solar).
A chart of the the month-by-month semi-scheduled economic and network curtailment totals, along with the top 3 worst hit units over 2023.
With Challicum Hills Wind Farm recently celebrating its 20th anniversary, Dan Lee takes a look into the long-term trend of technical and commercial performance of the oldest wind farms in the NEM.
The second part of an ongoing case study examining two successive days of low VRE generation in early July 2023. This part examines IRPM, earlier forecasts of available generation and maps the availability by...
With Q2 drawing to a close, we're gearing up to produce GenInsights Quarterly Update for this quarter. Timely to look back at Q1 at what was reported about curtailment of wind and solar in...
Inspired by the recent article by Tristan Edis (who referenced the GSD2022 in analysis of curtailment of some wind and solar farms), Allan O'Neil follows on with more analysis of the two main types...
Tristan Edis from Green Energy Markets takes a deep dive into generator performance across the NEM. He provides his take on which wind and solar farms have outperformed and underperformed, through the recent renewable...
Today, more than 14 months after the publication of GenInsights21 we're sharing Key Observation 15 of 22, relating to self-forecasting for Semi-Scheduled units.
On Thursday 17th March, Jonathon Dyson presented at the CEC Wind Industry Forum in Melbourne about the increasing role of auto-bidding and self-forecasting in the modern-day NEM. In this article, he shares some of...
Curtailment seems like a simple concept, until you look closely at the details. In this article, Marcelle looks at how to estimate curtailment at wind and solar farms and explores some of the traps.
In terms of diversity of intermittent supplies, we need to understand that we're not just comparing data series on a scale that runs from "highly correlated" to "random"...
