This dataset is published in relation to the article titled "Impact of the COVID-19 Lockdown on the Electricity System of Great Britain: A Study on Energy Demand, Generation, Pricing and Grid Stability" which is accepted to the Energies journal and also exists as a preprint(doi: |10.20944/preprints202011.0348.v1).

The dataset is separated into 4 categories following the structure of the paper: 
(1) Demand, 
(2) Generation, 
(3) Forecast and Grid Stability,
(4) Pricing.

The abbreviations used in the file names are explained below. More information can be found on https://www.bmreports.com/bmrs/?q=help/glossary.
