====== UK Power ======

This page serves to document some information I found regarding the UK power grid and the data available in relation to it.

===== Data providers =====

The national grid itself provides some real-time (ish; delayed by 2 minutes) data, but there is additional data provided by other parties.

  * Elexon - I have no idea who they are, but they provide per-megawatt usage of individual power sources.

===== Data sources and formats =====

==== Elexon ====

There are a number of data sources available from Elexon's "API", in varying formats. The data permitted to be automatically downloaded is listed at [[https://www.elexonportal.co.uk/SCRIPTING]]

Elexon also provide data through a more formal API, as well as through message queueing systems including AMQP, but I haven't explored that and don't have the energy to.
