Interruptions in electricity supply – ‘the lights going out’ – make for arresting headlines and capture public attention. Yet it is strikingly rare for any kind of electricity generation shortfall to trigger blackouts: major reliability events are nearly always the result of grid failure incidents such as wires frying or being damaged by trees.
Furthermore, none of the recent events that have occurred in markets with high shares of renewables have been caused by over-reliance on renewables to provide sufficient electricity supplies. In spite of this, the fossil energy industry has a track record of seizing on any opportunity to promote the narrative that more fossil generation is needed and that the growing shift to renewables is undermining and driving up the cost of secure supplies.
To dispel many of the myths surrounding the causes of recent significant power outages, the toolkit looks at four case studies: Texas 2021, California 2020, Great Britain 2019 and South Australia 2016.
These case studies prove it is important that advocates for a clean energy transition can set the record straight quickly, credibly and substantively. This package equips advocates with information and tools to respond quickly to the misinformation that spreads rapidly in the wake of power grid reliability events, and in particular:
- introduces the advocate to reliability events, and their causes and consequences;
- provides a checklist for advocates to understand and analyse emerging reliability events (a separate, interactive checklist can be downloaded here: Power Grid Rapid Response Checklist);
- provides holding lines for advocates during the information vacuum that normally proceeds a reliability event;
- explains why large-scale reliability events are almost always caused by network failures and not renewable electricity generation.
