A model project: the Thames Tideway Tunnel and the Regulated Asset Base model

Described by UK Chancellor George Osborne as a project the world can learn from, the Thames Tideway Tunnel (TTT) in London has attracted great interest from the market and media, both locally and globally. This is not only because of its size – with a value of £4.2 billion and spanning 25 kilometres under the River Thames – and complexity. Much of the interest has centred on its unique use of a Regulated Asset Base (RAB) model, a concept that gives pricing certainty to the private sector utility operators and their customers, to the benefit of both.

London-based Projects Partner Charlotte Morgan, who led the TTT project, has been in Australia to share her insights and lessons learned, especially around its use of the RAB model. The model has clear application to other infrastructure projects – particularly in the transport sector – with many Australian companies and governments keen to learn more about its benefits. This is a timely development for Australia, as we undergo our own asset recycling program, with opportunities for the private sector to invest in long-term and sustainable infrastructure being key.

Watch Allens Infrastructure & Transport Sector Leader Leighton O'Brien speak to Charlotte about the TTT project, the RAB model and her insights from this landmark project.
