UK Offshore Wind In 2030 – Calculated September 2026

The next general election is likely to be held in 2029, so how much wind energy will be added before the next Parliament?

The Current Position

The Wikipedia entry for the list of operational wind farms in the UK, says this.

In July 2025, there were offshore wind farms consisting of 2,809 turbines with a combined capacity of 16,035 megawatts.

Due To Be Commissioned In 2026

It would appear these wind farms will come on-line in 2026.

• Dogger Bank A – 1235 MW – Fixed
• East Anglia 3 – 1372 MW – Fixed
• Sofia – 1400 MW – Fixed

This would add 3 wind farms and 4,007 MW to give a total of 20,042 MW.

Due To Be Commissioned In 2027

It would appear these wind farms will come on-line in 2027.

• Dogger Bank B – 1235 MW – Fixed
• Dogger Bank C – 1218 MW – Fixed
• Inch Cape – 1080 MW – Fixed
• Llŷr 1 – 100 MW – Floating
• Llŷr 2 – 100 MW – Floating
• Norfolk Boreas – 1380 MW – Fixed

This would add 6 wind farms and 5,113 MW to give a total of 25,155 MW.

Due To Be Commissioned In 2028

It would appear these wind farms will come on-line in 2028.

• East Anglia 2 – 963 MW – Fixed
• Hornsea 3 – 2852 MW – Fixed

This would add 2 wind farms and 3,815 MW to give a total of 28,970 MW.

Due To Be Commissioned In 2029

It would appear these wind farms will come on-line in 2029.

• Green Volt – 400 MW – Fixed
• Norfolk Vanguard East – 1545 MW – Fixed
• Norfolk Vanguard West – 1545 MW – Fixed

This would add 3 wind farms and 3,490 MW to give a total of 32,460 MW.

Due To Be Commissioned In 2030

It would appear these wind farms will come on-line in 2030.

• Caledonia – 2000 MW – Fixed
• Erebus – 100 MW – Floating
• Five Estuaries – 1080 MW – Fixed
• MarramWind – 3000 MW – Floating
• Mona – 1500 MW – Fixed
• Morecambe – 480 MW – Fixed
• N3 Project – 495 MW – Mixed
• North Falls – 504 MW – Fixed
• Outer Dowsing – 1500 MW – Fixed
• Pentland – 92.5 MW – Floating
• Ramplion 2 – 1200 – Fixed

This would add 11 wind farms and 11,951.5 MW to give a total of 44,411.5 MW.

Due To Be Commissioned In 2031

It would appear this wind farms will come on-line in 2031.

• Awel y Môr – 775 MW – Fixed
• Berwick Bank Phase B – 1380 MW – Fixed
• Dogger Bank SE – 1500 MW – Fixed
• Dogger Bank SW – 1500 MW – Fixed
• Spiorad na Mara – 840 MW – Fixed

This would add 5 wind farms and 5,995 MW to give a total of 50,406.5 MW.

UK Offshore Wind Summary 2026 And 2031

I can now summarise UK offshore wind for the next few years.

• 2025 – 16,035 MW
• 2026 – 3 – 4,007 MW – 20,042 MW
• 2027 – 6 – 5,113 MW – 25,155 MW
• 2028 – 2 – 3,815 MW – 28,970 MW
• 2029 – 3 – 3,490 MW – 32,460 MW
• 2030 – 11 – 11,951.5 MW – 44,411.5 MW
• 2031 – 5 – 5,995 MW – 50,406.5 MW

Note.

1. The first figure after the year is the number of wind farms to be commissioned that year.
2. The middle figure is the expected capacity of the wind farms to be commissioned that year.
3. The last figure is the expected total offshore wind capacity at the end of that year.
4. Typically, we need about 30 to 35 GW to power the UK.
5. The next general election must be held by the 15th August 2029.

So whoever wins the election will inherit a windfall of just under 12 GW of offshore wind.
