Skip Rate - Summary

This is the summary skip rate and skipped volume data for each 30min period for each stage of exclusion described in the LCP methodology.

19/12/2024: in the data published today, we have corrected the handling of an edge case and updated the previous days’ data to reflect this change.

CKAN Data API

Access resource data via a web API with powerful query support.
Further information in the main CKAN Data API and DataStore documentation.

The Data API can be accessed via the following actions of the CKAN action API.

Query
`https://api.neso.energy/api/3/action/datastore_search`
Query (via SQL)
`https://api.neso.energy/api/3/action/datastore_search_sql`

Query example (first 5 results)
`https://api.neso.energy/api/3/action/datastore_search?resource_id=2a9f992d-8513-412a-9527-2f17a5638a00&limit=5`
Query example (via SQL statement)
`https://api.neso.energy/api/3/action/datastore_search_sql?sql=SELECT * from "2a9f992d-8513-412a-9527-2f17a5638a00" LIMIT 5`

A simple ajax (JSONP) request to the data API using jQuery.

var data = {
  resource_id: '2a9f992d-8513-412a-9527-2f17a5638a00', // the resource id
  limit: 5 // get 5 results
};
$.ajax({
  url: 'https://api.neso.energy/api/3/action/datastore_search',
  data: data,
  dataType: 'jsonp',
  success: function(data) {
    alert('Total results found: ' + data.result.total)
  }
});
