Abstract

With the operational lifetime of a tidal barrage stretching up to 120 years, it is important to be able to change the level of energy generation with varying trends in energy demand. Unlike other technologies, the energy generation level and sequence of a tidal barrage can be significantly altered without any physical change to the barrage by varying only the operational parameters. In order to explore this, a computational model which calculates the energy generation for a barrage across the Mersey estuary was developed. The model uses cutting edge double regulated turbine technology and bathymetric data and explores how this can be achieved without changing the physical parameters of the barrage. The derived results were compared to previous studies and found to match and exceed the results of past predictions.
