Mersey Estuary� Mean tidal range: 6.5m
� Basin area: 61km2
� Previous studies in the 1980’s (Mersey Barrage Company report in 1993: 700MW barrage)
In 2006 Peel Environmental Ltd and the North West R egional Development Agency (NWRDA) launched a pre-feasibili ty study –phase 1 (Consortium of consultants led by Bruno Hap pold + RSK + Univ. Liverpool)
