NPS 100C-24 100kW
Perfect for lower wind speeds
The NPS 100C-24 has a cut in speed of just 3 m/s and provides maximum generation at 12-15 m/s.
Reliable
Using direct drive technology and requiring no gear box, the NPS uses fewer moving parts. Northern Power Systems claim it is amongst the most reliable machines in its class.
Planning friendly
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 which 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 NPS have a vested financial interest in ensuring your machine is operating at optimum performance for the duration of the turbines 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.
Power Production
The NPS 100C-24 is a class IIIA machine with a 24m rotor diameter designed for maximising annual energy production (AEP) at sites with an average annual wind speed of 7.5m/s and below.
The direct-drive machine 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-24 at full output.
“From start to finish throughout planning, installation and the turbine’s performance afterwards I have been delighted with the Earthmill team”
