NPS 100C-21 100kW
Perfect for higher wind speeds
The NPS 100C-21 is a class IIA wind turbine designed for optimal performance in higher wind speeds. The turbine can withstand gusts of up to 59.5m/s.
The NPS uses direct-drive technology and requires no gear box. It therefore uses fewer moving parts, and according to Northern Power Systems is amongst the most reliable turbines in its class.
With 22m, 29m and 37m tower options available, the NPS 100C has a range of solutions to meet maximum tip height planning requirements in your area. A new colour has been used on the tower and nacelle to minimise visual impact.
Maximise your income
The 100kW generator takes full advantage of the maximum output capacity within the <100kW Feed-in-Tariff bracket, creating the best returns possible over its 20 year lifespan.
Simple grid connections
NPS turbines come with a 400-volt transformer and RTU data logger as standard as well as a utility grid protective relay interface (G59/2). The turbine produces electricity at an even frequency, simplifying your grid connection.
10-Year Performance Guarantee Programme (PGP)
Northern Power offer a 10 year PGP. The programme covers O&M costs, spare parts, labour and expenses for the NPS 100C.
The cost of the guarantee is calculated based on the performance of the turbine, and is backed by availability and power curve guarantees. This means that NPS have a vested financial interest in ensuring your machine is operating at optimum performance for the duration of its lifespan.
Also included in PGP:
• As well as being monitored by the Earthmill team, the turbine will have 24/7 management from the NPS operations teams in the UK, Italy and the U.S.
• Global Spares Management Programme: NPS offers a rapid spare-part delivery service for same or next day delivery which minimises ‘down time’ in instances when maintenance is required.
The NPS 100C-21 is a class IIA machine with a 21m rotor diameter designed for maximising annual energy production (AEP) at sites with an average annual wind speed of over 7.5m/s.
The NPS 100C-21 is a direct-drive machine which uses magnets instead of a gear box to enable the output to be ‘dialled back’ to a lesser amount. The model has proven ideal for areas with grid restraints.
The output can readjusted back to its full potential at anytime if upgrades are made to the grid infrastructure at a later date.
The graphs on the right show the power curve and AEP for the NPS 100C-21 at full output.
“From start to finish throughout planning, installation and the turbine’s performance afterwards I have been delighted with the Earthmill team”
