“…Some evidence for this can be seen in the experience of the USA and the UK over the last 30 years [134,135]. Increasingly weather related risks are becoming very significant in planning resource adequacy as highlighted for the US by Domah and Pollitt [136]. Approaches to improving resilience to the impact of extreme weather include upgrading components to make them more robust, employing effective operational procedures to improve supply restoration time and investing in transmission redundancy and smart grid solutions [132,133].…”

“…Just as there are sometimes years of drought, there may be certain events, for example, where wind speeds or solar irradiance is lower than normal for extended periods of time. A recent NREL study examined the impact of extreme weather on power system operations, identifying several events that may benefit from a deeper understanding by system operators (Novacheck et al 2021). Several key findings suggest that renewable energy does not markedly change the reliability during extreme events, such as cold or heat waves.…”

A Product of the South Asia Group for Energy 1 Electrification is used throughout this paper to indicate technologies using electricity as the source of energy or as the act of switching from another energy source, such as direct fuel use, to electricity. 2 For the purposes of this report, renewable energy will refer to wind and solar generation unless otherwise noted. 3 CEA's definition includes wind, solar, small hydro, and biomass.

“…While various implications of renewable variability have been explored in the literature, attention has recently shifted to the occurrence of prolonged periods with extremely low wind and/or solar availability, also referred to as "Dunkelflauten". This applies to both the research and the energy policy discourse in many countries [8][9][10][11][12][13].…”

As variable renewable energy sources increasingly gain importance in global energy systems, there is a growing interest in understanding periods of variable renewable energy shortage (''Dunkelflauten''). Defining, quantifying, and comparing such shortage events across different renewable generation technologies and locations presents a surprisingly intricate challenge. Various approaches exist in different bodies of literature, such as hydrology, wind and solar energy analysis, or energy system modeling. The subject of interest in previous analyses ranges from single technologies in specific locations to diverse technology portfolios across multiple regions, focusing either on supply from variable renewables or its mismatch with electricity demand. We provide an overview of methods for quantifying variable renewable energy shortage. We explain and critically discuss the merits and challenges of different approaches for defining and identifying shortage events and propose further methodological improvements for more accurate shortage determination. Additionally, we elaborate on comparability requirements for multi-technological and multi-regional energy shortage analysis. In doing so, we aim to contribute to unifying disparate methodologies, harmonizing terminologies, and providing guidance for future research.
