Introduction The Embedded Capacity Register (ECR), formerly known as the System Wide Resource Register (SWRR), lists all generation, storage and flexible demand resources where the installed generation capacity, export capacity or the import capacity is greater than or equal to 1MW. The ECR dataset provides comprehensive information about generation, storage, and flexible demand resources connected to the electricity distribution network. This dataset is crucial for understanding the capacity and distribution of these resources across different licence areas. It includes key characteristics: Export MPAN/MSID: Unique identifier for the export meter point administration number or meter serial identifier. Import MPAN / MSID: Unique identifier for the import meter point administration number or meter serial identifier. Customer Name: Name of the customer associated with the resource. Location Coordinates: Eastings and Northings coordinates for the resource location. Primary: The primary substation associated with the resource. Energy Source and Conversion Technology: Details about the energy source (e.g., solar, wind) and the conversion technology used (e.g., photovoltaic, wind turbine). Transformer ratings Methodological Approach Data Collection: The data is sourced from various internal systems, including the data warehouse and other operational databases. This ensures comprehensive coverage of all relevant resources. Data Integration: The collected data is integrated and organized to provide a clear view of the capacity and distribution of these resources across different license areas. This includes details such as location coordinates, energy source, conversion technology, and associated substations. Quality Control Statement The data is provided "as is". Assurance Statement We are aware that not all cells are fully populated on the ECR, we are working hard to gather and check data so that we can provide the missing information as soon as possible.
