The 1.4 GW project is being delivered as a 50:50 joint venture between ScottishPower and Masdar.

The Siemens Gamesa 14 MW turbine is around 262 metres tall with a rotor diameter of 236 metres. A single revolution of one turbine can generate enough electricity to power a UK home for more than four days.

The project is the first in the UK to feature 115-metre blades, which are seven metres longer than the previous offshore wind record of 108 metres, also set by Siemens Gamesa.

All 285 blades for East Anglia THREE are being manufactured in the UK at the company’s factory in Hull.

The project is expected to become operational at the end of 2026.

Global wind installations rise 40% 
Meanwhile, new data from the Global Wind Energy Council (GWEC) shows that 165 GW of wind capacity was installed globally last year, a 40% increase compared with the previous year.

The 2026 Global wind report indicates that this total includes 155.3 GW of onshore wind (up 42%) and 9.3 GW of offshore wind (up 16%). Global cumulative wind capacity has now reached 1,299 GW across 138 countries, with 28,395 turbines installed in 57 markets during the year.

China and India remained the largest contributors in Asia, adding more than 126 GW combined in 2025. China accounted for over 120 GW, while India installed a record 6.3 GW, nearly doubling its annual additions.

Europe added 19.1 GW of new capacity (up 16%), its second-highest annual total, supported by growth in Germany and Türkiye. The EU-27 installed 15.1 GW (up 17%), although this remains below the growth required to meet 2030 energy and climate targets, according to the report.

In the US, onshore wind installations increased by nearly 7 GW compared with the previous year.

Looking ahead, GWEC Market Intelligence projects that 969 GW of new wind capacity will be commissioned globally over the next five years, averaging 194 GW annually through 2030, equivalent to a compound annual growth rate of 5.2%.

While China is expected to account for around 63% of new installations in 2026, growth is projected to broaden geographically by the end of the decade, with increasing contributions from Southeast Asia, Central Asia, and Africa and the Middle East.

Global wind capacity is projected to exceed 2 TW by 2029, six years after surpassing the 1 TW mark in 2023.

US wind installations set to grow as market grows
A closer look at the US reflects this broader momentum, with new forecasts pointing to a near-term recovery alongside more measured growth through the rest of the decade, according to Wood Mackenzie’s US wind energy monitor report.

In comparison to GWEC, the report was even more positive, finding that installations rose to 8.2 GW in 2025, a 49% year-on-year increase, and are expected to reach around 11 GW in 2026, marking the strongest year for new capacity in five years.

In total, 48 GW of new wind capacity is forecast to be added by 2030, supported by a 15.4 GW pipeline of projects that have already cleared key commercial hurdles, providing a relatively high level of visibility in the near term.

Onshore wind is expected to dominate additions over the next few years, while offshore deployment is beginning to accelerate, with around 6 GW projected to come online by 2027.

However, the outlook remains uneven, the report warns. Policy uncertainty and permitting constraints – particularly involving federal approvals for land-based projects – continue to create bottlenecks, while elevated turbine and financing costs are adding pressure to project economics. Although recent clarity on tax incentives has improved near-term visibility, these factors could slow deployment beyond the current pipeline, even as rising electricity demand underpins the longer-term case for expansion.
