Huge new turbines could let biggest UK wind farm do more with less
The UK's largest onshore wind farm is set to be repowered with new, state-of-the-art turbines that will increase its power generation capacity while reducing the number of turbines.
The Whitelee wind facility, near Glasgow, is undergoing a significant upgrade that will see the installation of 124 new turbines, each measuring 787 feet tall and producing around 7 MW of power. This will increase the wind farm's total power generation capacity to over 1 gigawatt, making it one of the most powerful onshore wind farms in the world.
Repowering benefits
The repowering of the Whitelee wind farm is a significant example of how the wind energy industry is evolving to become more efficient and cost-effective. The new turbines will be able to generate more power than the old ones, while also reducing the number of turbines needed. This will not only increase the wind farm's power generation capacity but also reduce its visual impact on the surrounding landscape.
The main appeal of repowering is to access the much greater clean power generation, but there are other benefits too. For example, installing a new turbine gives project owners an easy opportunity to add state-of-the-art sensors that can detect birds and bats and slow the blades' rotation to protect them. New sensors can also spot potential mechanical issues before they become catastrophic.
Technical advancements
The new turbines being installed at Whitelee are a significant improvement over the old ones. They are taller, more efficient, and produce more power. The old turbines, which were installed in 2008, stood at 360 feet tall and produced 2.3 MW of power each. The new turbines, on the other hand, will stand at 787 feet tall and produce around 7 MW of power each.
| Turbine Model | Height | Power Generation |
|---|---|---|
| Old Turbines | 360 feet | 2.3 MW |
| New Turbines | 787 feet | 7 MW |
| 2013 Expansion Turbines | 459 feet | 3 MW |
Future prospects
The repowering of the Whitelee wind farm is not only a significant development for the UK's wind energy industry, but it also has implications for the global wind energy market. The use of larger, more efficient turbines is becoming increasingly common, and this trend is expected to continue in the coming years. In the US, for example, the average onshore wind turbine capacity has steadily increased from 0.8 MW in 2000 to 3.5 MW in 2024.
The US is also expected to see a significant increase in repowering activity in the coming years, with 10 GW of new wind capacity expected to come from repowering over the next decade. The Northwest and Midwest are expected to build the most repowered wind capacity, with significant capacity also expected in Texas, California, and the mid-Atlantic.
