Endurance X35 225kW
The most productive wind turbine in its class
The 225kW X35 incorporates a 35m diameter rotor. The large swept area makes it the most productive turbine in its class for sites with a wind speed lower 7.5m/s.
The original X-series design by Danish company Norwin, has now been generating clean energy around the globe for over 25 years. Having stood the test time, Endurance have added the latest technological refinements building on the proven design. The X-series is now manufactured in Endurance’s UK factory in the Midlands.
Despite an impressive power yield capability, with 30m & 40m tower height options, the X-35 still falls within farm-scale planning parameters, unlike larger 500kw+ turbines which usually require higher strategic level planning applications.
The X35 is best suited to farms, commercial and industrial sites with a lower average annual wind speed and high energy requirements.
“Being in the Midlands we have relatively low wind speeds at our site but the big blades of the X35 made our site financially viable”
David Spendlove, Derbyshire Farmer
Power Production
The Endurance X-35 is a 225kW wind turbine with a 35m rotor diameter. The large swept area – along with the efficiency of the generator – means that the X-35 offers a surprisingly high return even in areas with only a modest wind speed. The large rotor and low-level resistance generator allow the turbine to start producing energy at a wind speed of just 3.5 m/s.
A 225kW wind turbine is an ideal solution for landowners wishing to reap a higher power yield. Despite an impressive power yield capability, the X-35 still falls within farm-scale planning parameters, unlike larger 500kw+ turbines which usually require higher strategic level planning applications.
The AEP table allows you to see what the annual energy production is likely to be – based on the wind speed of your site. If you aren’t sure what your wind speed is you can find out by requesting a complimentary site assessment.
“The high electricity cost of running a dairy has prevented us from expanding. But the wind turbine will allow us to invest in doubling our capacity, hiring more local labour and buying more local supplies. ”
