I want to connect to the network, and I am not sure where to start.
I am connected to the network, and I want to learn more about utilising my assets and connection.
I want to collaborate with other stakeholders e.g. NESO, DNOs / DSOs, Local Authorities etc.
I want to conduct research into the network to improve our knowledge, develop new products or help understand my usage.
The Embedded Capacity Register (ECR) has been developed to provide better information to electricity network stakeholders on connected resources and network requirements. Each Distribution Network Operator (DNO) will host a register which will provide accessible information at a local and national level. The register uses a format agreed through the Energy Networks Association's Open Networks project, an industry initiative aimed at transforming the operation of energy networks and delivering a smart grid. Our register provides information on generation and storage resources (>=50kW) that are connected, or accepted to connect, to the electricity distribution networks owned and operated by us and it will be updated on a monthly basis. The register also includes information on the flexibility services that are being provided by connected resources, assisting to control or schedule demand and/or generation to reduce network constraints.
The Long Term Development statements provide information for anyone connecting to our distribution system at extra high voltage (EHV) level (including HV busbar of primary substations). It is designed to help to identify and evaluate opportunities for entering into arrangements with us relating to use of system or connection. Our statements include the following: network data; the likely development of our distribution system; plans for modifying the distribution system; and identification of parts of the distribution system that are likely to reach capacity limit in the next years. A long term development statement is available for each of our distribution network areas in central southern England and northern Scotland. Each statement has two sections, a summary (Part 1) and a detailed section (Part 2) both of which are available for download below.
Details of SSEN Substations, their type and identification and location coordinates for both SEPD and SHEPD licence areas. Derived from the Shapefile data and presented separately here for convenience.
Our Generation Availability and Contracted demand map for both north and south. Our map provides an indication of the networks capability to connect large-scale developments to major substations. Accompanying the map, the heat map spreadsheets for both of 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.
The map-based Powertrack tool allows our customers to get access to near-realtime outage data on the SSEN Distribution Network. This includes Planned and Unplanned Outages as well as some supporting information on affected postcodes and reasons for the outage.
