Vestas reveals offshore turbine with world's largest sweep

Each turbine is expected to deliver around 80 GWh of energy per year, depending on site-specific conditions, which is said to work out as being enough to power 20,000 European homes.

The V236-15.0 MW also offers the potential to reduce the number of turbines deployed at offshore windfarm level – with Vestas calculating that the "offshore turbine offers 65 percent higher annual energy production than the V173-9.5 MW, and for a 900-MW wind park it boosts production by five percent with 34 fewer turbines."

The company expects the first V236-15.0 MW prototype to be built in 2022, with serial production following two years later. It has a design lifetime of 25 years.

“With the V236-15.0 MW, we raise the bar in terms of technological innovation and industrialization in the wind energy industry, in favor of building scale," says Anders Nielsen, Vestas CTO. "By leveraging Vestas’ extensive proven technology, the new platform combines innovation with certainty to offer industry-leading performance while reaping the benefits of building on the supply chain of our entire product portfolio. The new offshore platform forms a solid foundation for future products and upgrades.”

Eoin Treacy's view

Boosting production and needing to build fewer towers suggests there should be cost savings in construction. The big change in renewable energy occurred in late 2019 when economies of scale improved enough that the wind and solar sectors could survive without subsidies. That has led to a complete reappraisal of the rationale for investing in the sector. More recently it has allowed the renewable energy sector focus on the subsidies provided to fossil fuel companies across the energy supply chain.
