The Swansea Green Power Barrage

just some numbers

• Cost of lagoon – £1.3bn (projected not actual)
• Electricity produced – 532 GWh pa, which is 0.15% of UK generation (projected not actual)
• This is enough to supply on average 40,000 homes
• Therefore the cost per household is £32,500
• There are an estimated 107,500 households in Swansea, so the lagoon could not supply half of the town.
• Even after the capital costs, ongoing costs will be substantial, for instance dredging and maintenance and replacement of turbines.
