Drought events involving only sources of energy production are known as energy production droughts . Energy supply droughts involve use of load, typically determined from the net load or the load after subtracting wind and solar production.

How long do wind and solar energy droughts last?

Standardized benchmark of historical compound wind and solar energy droughts across the Continental United States. Renewable Energy, ; 220: 119550 DOI: 10./j.renene..119550 DOE/Pacific Northwest National Laboratory. "'Energy droughts' in wind and solar can last nearly a week." ScienceDaily.

What is a compound energy drought?

These coincident, or compound energy droughts can be defined for any two or more variables, though typically wind and solar are of the most interest due to their extensive adoption and growing integration into grids across the world , , , , , , .

How do energy droughts affect the power grid?

As intermittent renewables continue their rapid expansion towards a decarbonized grid, the impacts of energy droughts on the power grid’s reliability, economic performance, and greenhouse gas emissions is increasing and thus needs further study .

What are persistent energy droughts (PEDs)?

Second, we examine ‘Persistent Energy Droughts (PEDs)’ 21, 32. These drought events occur when the daily residual load remains consistently above a predefined threshold for consecutive days. Additionally, we differentiate between summer and winter events by defining PED thresholds relative to the respective seasonal residual loads.
