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.nationalgrideso.com/api/3/action/datastore_search`
Query (via SQL)
`https://api.nationalgrideso.com/api/3/action/datastore_search_sql`

Query example (first 5 results)
`https://api.nationalgrideso.com/api/3/action/datastore_search?resource_id=9120ae56-f4b5-4512-baaa-e20f8b31a014&limit=5`
Query example (via SQL statement)
`https://api.nationalgrideso.com/api/3/action/datastore_search_sql?sql=SELECT * from "9120ae56-f4b5-4512-baaa-e20f8b31a014" LIMIT 5`

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

var data = {
  resource_id: '9120ae56-f4b5-4512-baaa-e20f8b31a014', // the resource id
  limit: 5 // get 5 results
};
$.ajax({
  url: 'https://api.nationalgrideso.com/api/3/action/datastore_search',
  data: data,
  dataType: 'jsonp',
  success: function(data) {
    alert('Total results found: ' + data.result.total)
  }
});

Title	Month
Type	yearmonth
Description	The month Balancing Services Use of System (BSUoS) forecasted for.

Energy_Imbalance_£m

Title	Energy_Imbalance
Type	number
Description	Energy imbalance is the difference between the amount of energy generated in real time, the amount of energy consumed during that same time, and the amount of energy sold ahead of the generation time for that specific time period. The monthly energy imbalance cost can be negative or positive depending whether the market was predominantly long or short.

Positive_Reserve_£m

Title	Positive Reserve
Type	number
Description	Positive reserve is required to operate the transmission system securely and provides the reserve energy required to meet the demand when there are shortfalls, due to demand changes or generation breakdowns.
Comment
Example	15.0
Unit	£m

Negative_Reserve_£m

Title	Negative Reserve
Type	number
Description	A Negative Reserve service can provide the flexibility to reduce generation or increase demand to ensure supply and demand are balanced. The service is held in reserve to cover unforeseen fluctuations in demand, or generation from demand side PV and wind.
Comment
Example	3.0
Unit	£m

Frequency_Control_£m

Title	Frequency Control
Type	number
Description	This is the sum of the Fast reserve and the Response costs. Fast Reserve provides the rapid and reliable delivery of active power through an increased output from generation or a reduction in consumption from demand sources, following receipt of an electronic dispatch instruction from National Grid. Fast Reserve service must commence within two minutes following instruction, at rates of 25MW or greater per minute and providing a minimum of 50MW. Response is a service we use to keep the system frequency close to 50Hz. Fast acting generation and demand services are held in readiness to manage any fluctuation in the system frequency, which could be caused by a sudden loss of generation or demand. There are three types of frequency response known as “primary”, “secondary” and “high”. The difference between primary and secondary is the speed at which they act recover the system frequency. Both primary and secondary react to low frequency conditions, and high response.

Constraints_£m

Title	Constraints
Type	number
Description	Actions taken by the ENCC for non energy system management reasons
Comment
Example	15.0
Unit	£m

Other_£m

Title	Other
Type	number
Description
Comment	This includes minor components which are any actions that don’t meet the defined rules to categorise costs. This also includes costs any costs required to manage voltage. We manage voltage levels across the grid to make sure we stay within our operational standards and avoid damage to transmission equipment. Voltage levels are controlled by reactive power, and we pay providers to help manage voltage levels on the system by controlling the volume of reactive power that they absorb or generate.
Example	10.0
Unit	£m

Restoration_£m

Title	Restoration
Type	number
Description
Comment	Restoration is the procedure we use to restore power in the event of a total or partial shutdown of the national electricity transmission system
Example	5.0
Unit	£m

Balancing Costs (Central) £m

Title	Balancing Costs
Type	number
Description
Comment	Total Balancing Costs
Example	220.5
Unit	£m

Estimated Internal BSUoS & ESO Incentive £m

Title	Estimated Internal BSUoS & ESO Incentive
Type	number
Description	The internal charges incurred by NGESO to fulfil system operator obligations plus recovery of the estimated revenue paid to NGESO under the incentive scheme. Profit is positive and a loss is represented as a negative.
Comment
Example	24.2
Unit	£m

Winter Security of Supply Cost (£m)

Title	Winter Security of Supply Cost (£m)
Type	number
Description	Winter security of supply cost is in anticipation of any potential requirement to put additional enhanced actions in place for Winter and will be recovered across the whole year. This cost could cover the need to make additional non-gas generation available to the ESO outside of the market, a shift of some coal procurement costs from prior years and the continuation of a mechanism to access demand flexibility.
