On WattClarity there have been many articles written, referencing curtailment of VRE (variable renewable energy). This might be:

Here’s a few articles that might prove especially useful on this topic.
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.

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 that earlier Quarterly Update.
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 of curtailment. Allan differentiates these as ‘forced curtailment’ and ‘economic offloading’
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 investment boom.
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.
