Approval of NESO's tCSNP2 Refresh Methodology
We have reviewed the National Energy System Operators’ (NESO) submission of the Second Transitional Centralised Strategic Network Plan Refresh Methodology and have decided to approve it.
NESO’s second transitional Centralised Strategic Network Plan Refresh (tCSNP2 Refresh) will plan the electricity transmission network needed in the 2030s. As part of this, it will reassess the network recommended by the second transitional Centralised Strategic Network Plan (tCSNP2) which was published in 2024, as projects have been developed further, to provide greater certainty on design, costs and delivery timescales. It will also consider the impact of Connections Reform and changes to offshore network designs and potentially support the development of the delivery pipeline for the CSNP which is due to be published by December 2028.
In this publication, we set out our decision to approve NESO’s tCSNP2 Refresh Methodology.
