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?

The graph also shows the total live Orkney Islands renewable generation as a proportion of the total renewable capacity. The generation can be greater than the live demand, which means that the excess will be exported to the Scottish Mainland. The additional renewable generation attributable to the Orkney ANM system is shown as a proportion of the total renewable generation. The total renewable generation does not include the significant amount of microgeneration (< 50 kW) installed on the network.

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’.
