Seabased's system is scalable. A wave energy park built using Seabased's concept can be expanded in stages. Electricity can be generated and delivered to the grid with only a few units installed. Consequently cost recovery can begin long before the entire wave energy park is completed. Seabased's generators have a nominal power of 10-50 kW. The installed power of a medium large wave energy park with 2000 generators, with an average power of 10 kW per generator, is 20 MW with an expected production of 50 GWh per year. Using Seabased's system electrical energy is expected to be generated at very competitive costs with no need for long term subventions or tax reductions. The global potential for wave energy is calculated to be 10 000-15 000 TWh per year. This is comparable to the economic potential for hydro power across the world.
