Offshore Wind Farms Could Supply Power to Millions of Homes

The Channel Islands could become major players in renewable energy, with experts suggesting offshore wind farms around Jersey and Guernsey have the capacity to power millions of homes across the islands, France, and the UK.

Energy firm Dyna, based in the islands, has highlighted the scale of opportunity, estimating that Jersey alone could support up to 60 turbines capable of generating as much as 1.5 gigawatts of electricity. Guernsey is thought to have even greater potential, with the capacity to double those figures.

Alongside the environmental benefits, advocates argue the economic rewards could be significant. Former States of Guernsey deputy Carl Meerveld believes large-scale offshore projects could generate hundreds of millions of pounds annually, providing a major boost to the island’s public finances. Guernsey’s government has already expressed interest in leasing seabed areas for windfarm development and exporting surplus energy to nearby markets.

In Jersey, policymakers are weighing up similar ambitions. States members voted earlier this year to explore the feasibility of wind power, with many pointing to the twin benefits of decarbonisation and energy security. However, ministers have urged caution, stressing the need for careful planning before committing to such a transformative project.

Industry leaders also warn of competition from neighbouring countries. If France accelerates its own offshore projects, it could reduce the islands’ export potential due to so-called “wind shadowing,” where nearby turbines lessen available energy.

Despite the challenges, momentum is building across both islands. Supporters say offshore wind could mark a turning point, not only in the transition to clean energy but also in shaping the economic future of the Channel Islands.
