Endurance X35Q 180kW

Making more sites work

The 180kW X35Q incorporates the same large rotor design as the X35 making the turbine well suited to areas with a lower average annual wind speed.

The ‘Q’ stands for quiet. A slower turning rotor enables the distance required between the turbine and neighbouring properties to be drastically reduced, rendering more sites viable for development.

Most local distribution network operators (DNOs) classify grid connections under 200kW as ‘small-scale’. This renders the smaller 180kW generator of the X35Q easier to successfully obtain a grid connection in constrained areas.

Despite an impressive power yield capability, the X-35Q still falls within farm-scale planning parameters, unlike larger 500kw+ turbines which usually require higher strategic level planning applications.

The X35Q can often be connected using a low voltage (LV) connection, which removes the need for an expensive ground mounted transformer and substation and drastically reduces the overall cost of connecting to the grid.

The X35Q is ideal for grid constrained areas, sites with a small acoustic setback distance and areas with a low average annual wind speed.

“We chose the X35Q as it is remarkably quiet. The 180kW generator made it possible to reduce our original grid quote for a larger connection from millions of pounds to something financially viable”

Andrew Pick, Yorkshire Farmer

Power Production

The Class 3 Endurance X-35Q is the perfect answer to smaller sites with lower wind speeds. With a large rotor diameter of 35m and a swept area of 962m2 the X-35Q cuts in and generates more power at sites with a lower average wind speed than class 1 & 2 turbines.

With a 180kW generator, the X-35Q connects to the grid with an LV connection, rather than a HV connection required by +200kW machines. This means grid connections are often much cheaper to secure for an X35Q and the smaller generator allows a greater chance of securing a connection in grid constrained areas. 

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 through Earthmill.

 

“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. ”
