Introduction Volume of Low Carbon Technologies (LCT) for both generation and demand (under 1MW) connected or accepted to connect to UK Power Networks Secondary Substations where: There are greater than 5 LCT connections (or accepted to connect) by Type; and The secondary site transformer serves more than 5 customers. This is done in the interest of protecting customer privacy.Update 22/10/2026: The Low Carbon Technology (LCT) dataset has recently undergone a comprehensive data quality review and enhancement programme, including the adoption of new and improved data sources, resulting in improved accuracy, completeness, and overall reliability. These improvements have resulted in changes to some of the aggregated data published on the Open Data Portal. Key improvements include: The inclusion of historical requests received outside of the Smart Connect Portal following its launch in March 2021 (for example, requests and notifications submitted via email). The removal of duplicate entries resulting from multiple enquiries for the same installation. Improved tracking of capacity changes between the initial request stage and final installation. More regular reconciliation against MCS certificate data to identify and address gaps in the data Enhanced connectivity and network location data. Methodological Approach LCT application data (which captures, amongst other things, the location, LCT type, and capacity) is taken from our Smart Connect portal at https://www.ukpowernetworks.co.uk/smart-connect and via email enquiries; Using the MPAN (Meter Point Administration Number), we look up our connectivity model to ascertain the upstream connecting secondary and primary substations; and Data is then aggregated to the secondary site where there are greater than 5 connections. Quality Control Statement Quality Control Measures include: Verification steps to match features only with confirmed functional locations; Manual review and correction of data inconsistencies; and Use of additional verification steps to ensure accuracy in the methodology. Assurance Statement The Open Data Team has checked to ensure data accuracy and consistency.
