NAIK_Image_UKDKtrip060608RF041_360x271NaiKun envisions an offshore wind project off the northwest coast of British Columbia providing a range of electricity generation capabilities from 400 megawatts in the first phase up to a possible 2,000 or greater megawatts.

Since project planning began a decade ago, there have been major advances in offshore wind technology and engineering, ensuring that NaiKun’s project today can be delivered as efficiently as possible and at a greatly reduced cost.

“Our goal is clearly to reduce the cost of electricity from offshore to less than ten cents per kilowatt-hour…”Markus Tacke, CEO of Siemens Wind Division

Experts in Engineering, Design and Construction

NaiKun’s partners include Siemens and other internationally renowned experts in procuring, financing, building and operating large-scale renewable energy projects. This combined expertise will ensure the most cost effective and innovative solutions are available for the construction and operation of the NaiKun Project.

Project Layout

NaiKun is at an advanced state of development and has completed a detailed engineering design, operating plan, and turbine layout. The NaiKun Project would be located off the coast of Haida Gwaii in Hecate Strait, an area known for strong, consistent and reliable wind, where up to 110 wind turbines will be installed to provide provide 400 megawatts of clean, renewable energy to serve more than 200,000 B.C. homes.

NaiKun has entered into a Preferred Supplier Agreement with Siemens to use its new SWT-4.0-130 4MW turbines. The new wind turbine is based on the proven technology of Siemens SWT-3.6, the world’s most popular offshore wind turbine. The new technology includes upgrades to generator and rotor allowing for up to a 27% increase in annual energy production. These ongoing technology advances continue to improve productivity and the cost of electricity. For example, the 6 MW turbine under development has 50% fewer moving parts.

NaiKun has completed geophysical surveys of the project site, which includes detailed mapping of the seabed, water depth, topography and other related information that has supported the development of the most efficient project layout and engineering.

“During its entire lifecycle the wind power plant produces 23 times more energy than it consumes.”Siemens, 2014

Location – Why Offshore?

Wind over the water is generally stronger and more consistent than wind over land. With fewer obstructions such as hills, man-made structures or even trees, offshore wind produces more energy, more efficiently than onshore wind.

Wind, wave and climate data collected from NaiKun’s state-of-the-art meteorological station in Hecate Strait, together with data from the nearby Rose Spit weather station has yielded more than 19 years of data. All data confirms the Hecate Strait’s wind resource to be “world-class in nature”.

How Will Electricity Generated get to Homes and Businesses?

Submarine cables are used to transmit electricity from the offshore wind turbines to a transformer station on land. Here the voltage is converted and electricity is transmitted to homes and businesses within the existing electricity transmission grid. In British Columbia, BC Hydro is the main purchaser of power for redistribution to residential and business customers.
