The ‘Carry-over Network Innovation Allowance’ (the CNIA) is a licence condition included in the RIIO-2 licences which allows electricity transmission, gas transmission, and gas distribution licence holders to carry any unspent 2020-2021 RIIO-1 NIA allowance over into the first year of RIIO-2 in 2021/2022. The CNIA licence condition in the Electricity Distribution licence allows licence holders to carry forward unspent 2022/23 RIIO-ED1 NIA funds into 2023/24 (the first year of RIIO-ED2).



As this requires additional reporting guidelines we consulted on amendments to the existing RIIO-1 NIA Guidance documents to reflect this time extension.



We published Version 4 of the RIIO-1 Gas NIA Governance and Version 4 of the RIIO-1 Electricity NIA Governance on 30 March 2021, alongside track change versions of both of these documents that highlight where changes have been made.



We have now published Version 5 of the RIIO-1 Electricity Network Innovation Allowance Governance Document, alongside the modifications to the Electricity Distribution licence ahead of the start of RIIO-ED2.
