Distribution Network Options Assessment

Information
Introduction

Introduction

The DNOA output shows future network constraints, the recommended solution, and the current status in the solution progress. It indicates when, where, and at what volume flexibility services will be required in the next few years.

This dataset will be updated annually by the end of the first quarter each year.

Due to the differences in the publication date of databases such as the LTDS, DFES NSHR, and the DNOA, there can be differences in published data.

Methodological Approach

  • DNOA Methodology: Our methodology document can be found here.
  • FLOC association: Using FLOCs, we associate the DNOA data to our grid and primary substation FLOCs, which allows us to generate geopoints.

Quality Control Statement

Quality Control Measures include:

  • Verification steps to match features only with confirmed functional locations.
  • Manual review and correction of data inconsistencies
  • Use of additional verification steps to ensure accuracy in the methodology

Assurance Statement

The Open Data Team and Network Options Team worked together to ensure data accuracy and consistency.
