The 'Orkney Smart Meter Volumes' data set has been created by cross referencing the number of smart meter installs as of 26.02.2025 at a dataset_id level via the total_mpan_count column in the open data portal, Smart Meter LV Feeder Data 'LOOKUP' tab and cross referencing this with the associated postcode data available through the full export file available via the open data portal Smart Meter LV Feeder Data page. The list of Orkney postcodes have been taken from doogal.co.uk

ssen-distribution-data-roadmap

The Data Roadmap was created looking at 5 main areas:

*  Retrospective – what existing data does SSEN have that stakeholders would benefit from?
*  Prospective – what data is SSEN going to produce in the near term  that stakeholders would benefit from?
*  Stakeholder requests/feedback – obtained through direct requests via the data portal as well as stakeholder feedback from surveys, roundtables, etc 
*  Legal requirements – e.g., from a regulatory standpoint 
*  Future looking – what are customers or partners asking for in the future?

Register Definitions and explanations within the Embedded Capacity Register.
For each site that meets the criteria to be included in its Embedded Capacity Register, each DNO/IDNO Party shall use reasonable endeavours to populate all relevant fields in the Embedded Capacity Register. Where the DNO/IDNO Party does not hold data for a specific field for a specific site, then the DNO/IDNO Party will populate the relevant field with the words ‘data not available’. If a specific field is not applicable to a specific site, then the DNO/IDNO Party will populate the relevant field with the words ‘data not applicable’.
