The UK marine gross electricity production is projected to increase steadily from 2024 to 2028, growing from an estimated 17.27 Gigawatt-hours in 2024 to 21.24 Gigawatt-hours in 2028. This represents a compound annual growth rate (CAGR) of approximately 5.28% over this period. The year-on-year growth rates indicate an average increase of around 4.89% annually compared to the previous years, where actual data preceding 2024 showed varied trends.

Key future trends to watch for in the UK marine electricity sector include:

Further technological advancements in marine energy technologies which could enhance efficiency.
Government policies and regulatory changes that may either boost or hinder the deployment of new marine energy projects.
Investment in infrastructure and grid integration to support increased electricity production.
Environmental considerations and public acceptance which can impact the pace and scale of project development.
