  • Network Innovation Allowance Annual Summaries

  •  NIA web iconThe Network Innovation Allowance states that the Network Licensee must produce an annual summary of its NIA activity to cover each Formula Year. This summary should:

    • Summarise the progress of the Network Licensee’s NIA activities in the Formula Year;
    • Summarise how the NIA activities link to the Network Licensee’s innovation strategy; and
    • Highlight areas of significant new learning.


    In accordance with regulatory requirements all current and previous Annual Summaries for National Grid can be found below. The ENA Smarter Network Portal hosts the Annual Summaries for all Energy Network Licencees.
