Elexon
Historical data - Past
Historical data is available from the Elexon Insights Solution website. This site provides detailed data on the source of power.
If you would like to check our historical data - or to find some more - click on the link to Generation.
PLEASE NOTE: Sometimes there are data missing from the Elexon historical data. This doesn't happen often, but it does happen. If you review the Elexon data you will see that occasionally the data for one or more half hour periods are missing, or obviously incorrect. When this happens, we use linear interpolation to estimate the missing values. This only happens occasionally, and when it does there seems no better alternative to this element of interpolation/estimation. It is only done when the data are clearly "missing", rather than in situations where (for example) a generation source has suddenly stopped generating! As far as we are aware, all other analyses based on Elexon data use the same or a similar approach. The missing data typically covers a small number of half hour periods.
Ofgem Renewable Obligation Certificate (ROC) records
Historical data - Past
Use the Ofgem reporting facility to get details of monthly generation data for any generation facility that is subject to the ROCs scheme.
One way of doing this is to use the Accredited Station feature first to determine the Accreditation No. of the facility you are interested in, then to use this with the Certificates option to determine the generation data for any period of time. In both cases make sure that you set the Technology Group value to the appropriate value, e.g. On-shore Wind.
