The low noise profile and new colour minimise the acoustic and visual impact for easier planning applications » Generate profitable income • Maximise the UK’s Feed-in-Tariff (FiT) using the largest allowed turbine (100 kW) within the tariff band • With low ownership costs over the lifetime of the turbine, the NPS 100C-24 pays for itself quickly and will generate a healthy income stream over its 20+ year life » Plug and play Installation is straightforward as the standard configuration for the NPS 100C-24 is grid ready. Supplied with an approved 400-volt transformer, an RTU data logger and a utility grid protective relay interface (G59/2) all built into the tower of the wind turbine. Our state of the art power converter design provides smooth, clean power to local grids, which simplifies grid connection 10-Year Performance Guarantee Programme (PGP) The 10-Year PGP covers 10 years of operation and maintenance costs, including parts, labour and expenses for the NPS 100. This is the only such warranty offered by a manufacturer for a small wind turbine in Britain. The annual cost is based on the performance of the NPS 100. This is backed by an availability guarantee and performance to power curve guarantee. 95 kW, 3 Phase, 400 VAC, 50 Hz Power Factor Set point adjustable between 0.9 lagging and 0.9 leading Reactive Power +/- 45 kVAR Grid Interconnect Utility approved protective relay included Noise Apparent Noise Level 50 dBa at 50 metres from nacelle Environmental Specifications Temperature Range Operational -20°C to 40°C Temperature Range Storage -30°C to 50°C Lightning Protection Receptors in blades, nacelle lightning rod and electrical surge protection During the programme NPS will be the sole service provider. This gives peace of mind that the wind turbine will produce maximum energy and return on investment while offering the lowest total cost of ownership for the turbine’s 20+ year life. With the 10-Year Performance Guarantee Programme, Northern Power Systems is financially invested in the success of your wind turbine. Other services in the Northern Power PGP include: • 24x7 monitoring and reporting: Operation teams in the UK, Italy and the United States oversee the performance and operation of your wind turbine to ensure maximum availability • Global Spares Management Programme: New parts for the NPS 100 dispatched for same-day or next-day deliver y
