Q: Why has National Grid implemented the Connected Data Portal and what purpose does it serve and what are the benefits?

A: The site will act as a centralised repository for all data that can be shared openly (initially) to drive further forwards our Presumed Open data culture and wider Energy Data Taskforce Report recommendation. The benefits of the Portal include offering powerful ways to easily search our data without the need for download, consume data via Application Programming Interface (API) and providing detailed descriptions (metadata and data dictionaries) to get a clear understanding of the datasets.

Q: How does National Grid Connected Data Portal fit in with the other avenues of WPD data provisions such as the website?

Q: Will National Grid be publishing new datasets?

A: We have already added several new datasets and will continue to work with our internal and external stakeholders to identify potential new datasets for publication on the Portal, utilising our Presumed Open Data approach.
