Tidal Lagoon Power Ltd (TLP) is planning to undertake the construction of the Swansea Bay Tidal Power Plant in the UK.

The project involves the construction of a 320MW tidal power plant. The project will include an oyster-shaped offshore visitor center and national triathlon and water sports facilities.

The project includes the installation of 16 turbine housings, sluice gates, flood doors, rails, electrical controls and hydraulics, the construction of precast concrete components, 9.5km seawall, 10km sea reef, education center, art center, a visitor center, ancillary buildings and other related infrastructure facilities.

In April 2013, Intertek Energy & Water consultancy services has been appointed as a Study Consultant for the project. KGAL has been appointed as the M&E design specialist.

LDA Design and Porta Planning has been appointed as Master Planner.

In June 2013, Alstom signed a Memorandum of Understanding with TLP to design and build the generating units. Alstom will work in partnership with TLP to create an optimal solution for the low head tidal lagoon.

In July 2013, Costain, Atkins, and Van Oord reached agreements to partner with TLP to design, build and deliver the project. Costain will work alongside all partners to coordinate and manage delivery.

Tencate will supply the Geotubes, which are filled with dredged material from within the lagoon footprint, largely sands and gravels, which are pumped in hydraulically. The water from this hydraulic pumping process is then forced out through the permeable geotextile membrane leaving very strong, compact sand-filled tubes which form the core structure of the wall.

FaulknerBrowns LLP has been appointed as an Architect for International watersport & hatchery center and Juice Architects for Visitor Centre.

In February 2014, TLP submitted planning application to National Infrastructure Planning for approvals.
