The concept of a Swansea Bay tidal lagoon has been developed over recent years demonstrating its engineering feasibility, contribution to decarbonisation of energy production and economic development based upon the creation of new industrial capabilities. In parallel the realisation of a City Deal for the Swansea Bay City Region (involving key public sector partners with the Welsh and UK Governments) has created a joint approach for major infrastructure initiatives, including an “Internet of Energy”. It is intended to build upon the initial designs, but to promote a re-formatting of the lagoon project to enable delivery by a private sector partner and to work with Swansea and the City Region to create a new stand-alone and independently financed multi-asset class development with the lagoon as its centrepiece. The project will involve a strategic review of the overall project, design work; development of business plans; securing of necessary investment, construction and operation.
