There is a lot of energy present in waves and tides of the oceans that’s called tidal wave power yet currently the energy derived from oceans is minuscule as the total energy currently comes in at just about 513 megawatts installed that comes mostly from two tidal barrage facilities located in South Korea and France.
How Much Energy Has Been Added?
With only about 1.6 megawatts added in 2024, MeyGen in Scotland is considered the largest tidal wave power stream project and in February 2026 the UK gave out contracts for an additional 20.9 megawatts pushing the pipeline total above 140 megawatts. Thus far there have been no contracts granted to wave energy projects in the UK.
What Is The Potential?
According to a report by IEA ocean energy program the potential installed capacity for wave and tidal wave power energy can reach up to 300 gigawatts by year 2050 and tides can give predictable energy unlike the wind energy which makes tidal energy more appealing for many users but analysts still think that tidal energy becomes economically feasible only having installed capacity around 1 gigawatt.
What Are Issues Concerning Ocean Energy?
Main hindrance of current ocean energy projects in the UK is the price, namely the UK tidal projects are asking for subsidies of about £172 for megawatt-hours, triple wholesale prices. Harsh seas and grid links add delay, so ocean power for now complements renewable power such as geothermal.
