Statistical quality

Through combining administrative datasets and contact information, the study aims to achieve complete coverage of energy generation in Wales.

For a small number of low carbon energy projects it is not possible to identify the local authority. In the case, the projects are included under an 'unknown' category, but are included within the Wales total.
