The Energy Networks Association, which is running the Open Networks Project, has announced the completion of its project to publish System Wide Resource Registers, detailing connected generation over 1MW on the distribution networks.
Each Distribution Network Operator (DNO) has published details of generation projects, storage facilities and flexibility services of 1MW and greater on their networks. Over 5,000 connected assets are recorded.
The project forms one of the outputs of the Open Networks project, which brings together electricity transmission companies with trade associations, BEIS, and energy regulator Ofgem, to lay the foundations for the smart grid and the DNO's transition to become Distribution System Operators (DSOs).
The new registers present a standardised set of data, highlighting demand and presenting opportunities for stakeholders - such as community groups, renewables projects and aggregators - to offer generation, storage or other services.
The improved transparency and data access are expected to help accelerate the transition to net-zero, as well as helping DNOs to avoid physical reinforcement works.
The information will also provide a more complete network overview of network generation capacity to National Grid ESO.
Harnessing the power of data, improving transparency, and harmonising processes across the country is another step forward to help us deliver the low carbon, smart grid that the public need
David Smith, chief executive, ENA
The register contains information on resource types, locations, and capacities resources that are already connected to the distribution networks, or that have accepted connection agreements in place.
Information on flexibility services provided to the distribution network companies is also included.
The new registers are produced in a standard format across the country, helping to harmonize local markets and making it easier for third parties to explore opportunities.
They will be updated on a monthly basis by each of the DNOs. Later this year, the registers' scope will be extended with information about the network reinforcements required to connect new resources.
Commenting on the release, David Smith, ENA chief executive, said: "Innovation and investment from the electricity network companies have already helped to make the UK a superpower of renewable energy.
"Harnessing the power of data, improving transparency, and harmonising processes across the country is another step forward to help us deliver the low carbon, smart grid that the public need.
"The publication of the System Wide Resource Registers will make connecting to the networks easier across the country, highlighting new opportunities for clean energy projects, delivering value for the public and securing our energy into the future."
