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’.

generation-availability-and-network-capacity

Generation Availability and Contracted demand map for both north and south giving the constraint level for GSPs and BSPs. Our map provides an indication of the networks capability to connect large-scale developments to major substations. The data is updated monthly.

Generation Availability and Network Capacity Maps

Generation Heat Map. The heat map for both our network regions provides Grid Supply Point (GSP) details, GSP and substation transformer ratings, Fault level information, and contracted and quoted generation projects at each GSP.

SEPD Generation Heat Map Update - September 2023

SEPD Demand Heat Map Update - September 2023.
The Demand Heat Map provides information on ongoing constraints and reinforcement works against GSP, BSP and Primary substations, and projects for new demand both contracted and quoted.

Percent_Loading

The view displayed here, is based on 2023 baseline loading with the projected forward DFES out to 2050. While many assets are showing as becoming overloaded over time, in reality we have extensive reinforcement & replacement planned on the network which is not represented in this view.

Baseline demand is fixed across the entire duration & does not reflect expect long term macro-economic or underline volume trends.
