Common Information Model LTDS

The Common Information Models (CIM) provide a complete and consolidated view of our network assets and their connectivity. The models bring together a huge range of datasets from different types of energy network infrastructure equipment, sensors and assets, including transformers, circuit breakers, wires and cables.

Notes on the models and their use 1. A Winter Peak Demand and Summer Peak Generation model are provided, where the Summer Peak model assumes 30% of the Winter Peak demand.

1. It is possible to run load flow analysis for a single case within a power system model, but this is only available for the intact model.

2. Network data is currently represented schematically, further work is being undertaken to represent this data geographically.

3. Some data within datasets is known to be incomplete – work is underway to improve and complete these datasets.

4. These models have not been validated for fault level studies or any other studies beyond intact load flow.

5. Models are in CGMES version 2.4.15 format.

6. Whilst this data represents our current view of the network, for full design and planning activity our Long Term Development Statement (LTDS) data should be used, which is accessible here
