Electrical generation data is at the geographical level of Great Britain (Northern Ireland is not included) and at 30 minute intervals. It is publicly available data from National Grid’s and Elexon’s websites.

SOLAR is National Grid’s estimate of solar generation

WIND is a combination of measured generation from transmission connected wind and National Grid’s estimated distribution connected (embedded) wind

HYDRO is measured generation from hydro that is not pumped storage e.g. run of river

PUMPED STORAGE is measured generation from hydro pumped storage

OC NATURAL GAS is measured generation from open cycle natural gas turbines

CC NATURAL GAS is measured generation from combined cycle natural gas turbines

OIL is measured generation from oil fuelled power plants

IMPORTS are the total of measured imports and exports of electricity for a 30 minute period (if negative this will show up under the title EXPORTS)

COAL is measured generation from coal fired power plants

OTHER is measured generation from power plants that include landfill and biomass

NUCLEAR is measured generation from nuclear power plants

EXPORTS are the total of measured imports and exports of electricity for a 30 minute period (if the value is positive this will show up under the title IMPORTS)

WIND+SOLAR+HYDRO is the combination of these three weather dependent renewables

RENEWABLE is WIND+SOLAR+HYDRO+0.85 x OTHER (as an estimate for the BIOMASS component of OTHER)

LOW-CARBON is RENEWABLE + NUCLEAR
