With a 20 percent Feed-in Tariff degression planned for April 2015, the new rotor – available at no additional cost to new buyers - will help landowners considerably lessen the impact of this anticipated revenue loss and further bring down energy costs on site.
“The new 24 metre rotor size will help us to maximise the financial and practical benefits we provide to landowners,” said Ivo Arnús, Director of UK Business Development, Norvento.
“Crucially, it does this whilst maintaining the certified design features that make nED100 one of the safest, most efficient and reliable medium-scale turbines on the market – and at no extra cost to the buyer," Arnús continued.
“As the UK distributed wind sector prepares to enter a post-tariff phase, the only realistic way for landowners to guarantee long-term returns is to invest in a turbine that is still performing close to capacity in 20 years’ time.”
By lengthening each blade by one metre, Norvento has enlarged the overall rotor diameter to 24m, two metres longer than the existing 22m model, thereby increasing the swept area of the blades by more than 72m2. This swept area increase allows nED100 to harness significantly more energy and boost its efficiency in all wind speeds.
Despite this enlargement, the impact of nED100 with regards to planning remains very small. The subtle increase in blade length does not significantly alter the turbine’s overall visual impact.
Furthermore, the new rotor diameter has been designed to spin at slightly lower revolutions than the 22m model in order to maintain an identical tip speed ratio, which, in practice, means that both models have the same operational noise levels. The new rotor size also operates nED’s unique low noise mode designed for noise sensitive locations, Norvento said.
