The project is backed by multinational oil company Royal Dutch Shell and the UK government, though Kite Power Solutions business development director David Ainsworth says the project will be "tariff-free." For one, the cost of mooring the kites is far less than mooring wind turbines, since the kite system essentially floats. The kites fly up to 450 meters in a figure-eight pattern and pull a tether attached to a turbine to produce electricity. Two kites alternately rising and falling ensures continuous power.

A single 40-meter-wide kite generates two to three megawatts of electricity and a field of roughly 1,000 kites "would produce as much electricity as the planned Hinkley Point C nuclear power station if the wind blew constantly," according to Independent.

The Stranraer region is inundated with wind and Kite Power Solutions expects just 10 days a year when the system won't generate power. In these cases, the company will use a small fan to keep the kites afloat as they wait for more wind.

Kite Power Solutions already established a small kite-power system in England's Essex county, and there's a large research project in Italy that uses kites to generate energy.
