Introduction The Embedded Capacity Register (ECR) lists all generation, storage, and flexible demand resources where the installed generation capacity, export capacity, or import capacity is 50kW to 1MW.Note: Please note, in the November 2025 publication, an additional 230 records were included. This data has been provided by MCS (Microgeneration Certification Scheme) where installers have not previously notified us of installations.  In publishing the data we aim to provide greater visibility of the number of installations. More information can be found here: Embedded Capacity Register 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; and 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. If you notice any errors or omissions, please email us at DG-Q&A@ukpowernetworks.co.uk.
