Mott MacDonald has been appointed owner’s engineer by Gas Natural SDG SA for the development of two new private power stations to be built in Spain. The 800 MW combined cycle plants will be built in Arr?bal in the north and La Plana del Vent close to Tarragona in the north-east. Both plants will feed into the local grids providing much needed additional power.

Each plant will comprise 2 x 400 MW units incorporating gas turbines in single shaft, combined cycle configuration with assocIated cooling towers and auxiliary plant. Fuelled by imported natural gas, they will use the latest generation gas turbine technology to maintain efficiency at some 56%. The work is being carried out by a local project team which includes Idom and Inypsa as Spanish sub-consultants. Specialist support is being provided from Mott MacDonald’s Brighton office.
