These solutions have much longer lead times but engagement on them has begun now as part of the Regulators’ Alliance for Progressing Infrastructure Development (RAPID) process. It should be noted that they are both in the early stages of development and delivery is more than 10 years in the future. The maturity of the information reflects this early stage development, and that it may change as the options are developed further.
We’ll update these pages with more information as the proposals progress.
