100 kW Vertical Axis Wind Turbine

Name: 100 kW vertical axis wind turbine
Brand: WINDTURBINE
SKU: GH-H100K
Availability: InStock

The GH-H100K is the top of the H-type range: a 15 m diameter, 20 m tall rotor, 300 m² of swept area, on a 20, 24 or 30 m free-standing tower. Five aluminium-alloy blades in three sections each, three layers of inner blades, and a permanent-magnet synchronous generator at ground level through a vertical shaft. Cut-in 2.2 m/s, rated 11 m/s, survival 45 m/s, 45 dB(A) at 10 m, IP55 from -50 °C to +60 °C.

A 5.5 m/s site gives about 190,000 kWh a year; a 7 m/s coastal site closer to 260,000. That is a village, an island grid or a mine camp — and in each case the comparison is a diesel genset at 0.30–0.45 USD/kWh, not a grid tariff. The structural argument for choosing it over a 100 kW horizontal axis machine is maintenance: at 100 kW the nacelle of a HAWT is 30 m up and needs a crane or a climb, while this machine's entire service envelope is at the base.

Design details

15 m × 20 m rotor, 300 m² swept area

Five blades, three sections each, bolted on site. The rotor turns at 20–28 rpm, so tip speed stays under 45 m/s and noise stays at 45 dB.

Everything serviceable at ground level

Generator, brake, slip-ring-free shaft coupling and switchgear sit in a base housing. No crane for routine maintenance, no working-at-height permit.

300 m² of swept area in a 15 m footprint

The rotor occupies a 15 m circle instead of a 30 m one — the reason this machine gets permitted where a 100 kW HAWT would not.

45 m/s survival with locked rotor

Designed for gusty coasts and ridges; typhoon-exposed sites are quoted the GH-D100KW instead. Blades are aluminium alloy, so no leading-edge erosion in sand or salt.

Where it is used

Island and remote community grids

One unit with 80 kW of PV and a 300 kWh battery carries a 40–60 kW baseload and cuts diesel run-hours by 60–70 %.

Mining and construction camps

Displaces fuel on sites where the wind is gusty, the load is flat and the nearest crane is a day away.

Industrial self-consumption

Feeds a 380 V bus behind the meter at a factory or cold store with a 45 dB boundary limit and limited land.

Frequently asked questions

How much does a 100 kW vertical axis wind turbine cost?

USD 82,000–108,000 ex-works with generator, controller and brake; USD 180,000–240,000 installed with tower, foundation, cabling and grid interface. Tower and civil works are 35–40 % of that.

Is this really the largest H-type you build?

Yes. The H-type range runs 1, 2, 3, 5, 10, 20, 30, 50 and 100 kW. Above 100 kW we supply the GH-D horizontal axis series to 200 kW, because a larger H-rotor needs a rotor diameter that stops making structural sense.

How is a 20 m blade shipped?

In three sections per blade, 15 units per machine, packed into two 40 ft containers with the arms and the base housing. Site assembly takes 5–7 days before erection.

What wind class does it need?

It is designed for a 45 m/s survival gust. On a site with a 50-year gust above 45 m/s — typhoon belts, exposed Caribbean or Pacific coasts — specify the GH-D100KW, which is designed to 59.5 m/s.

Does the low rotor speed mean a bigger generator?

The generator is direct-drive and sized for 11 m/s rated wind at 20–28 rpm, so it is larger and heavier than a geared equivalent. That is the trade for having no gearbox to service at height.
