GHREPOWER Powering Your Future

The GHREPOWER 50kW wind turbine has a gearless design, offering the advantages of:

• Greater simplicity and reliability

• Quieter operation

• Greater efficiency

GHREPOWER can supply a complete wind energy system, which includes the turbine, controller, inverter and associated cabling. All components of the system come with a 5 year manufacturer’s warranty. GHREPOWER can also offer a five-year maintenance contract.

The GHREPOWER 50kW wind turbine is currently undergoing MCS testing, with certification expected imminently.

Current Installations

There are three GHREPOWER 50kW wind turbine installations in Scotland, in addition to 23 others worldwide, in countries including the USA, Sweden, Italy and Belgium. In Scotland, one GHREPOWER 50kW wind turbine is at the TUV testing centre, undergoing MCS testing, and two are installed at Bathgate Sports Centre in West Lothian. It is possible to arrange a visit to these turbines, if desired.

Noise

The noise characteristics for a turbine with a 25m hub are as follows:

Wind speed at hub 6 m/s 10 m/s 15 m/sNoise at base (dB(A)) 58 60 62

This data is based on results of internal testing provided by GHRE China to GHRE UK on 11th February 2011.

Note that the sound power level of a wind turbine depends on several factors such as but not limited to regular maintenance and day-to-day operation. Therefore, this information does not constitute a warranty towards the customer that the wind turbine will meet the exact sound power level values provided in this document at any project specific site.

Crane and Access Requirements

The turbine components will be delivered in standard 40 foot shipping containers. The turbine requires a 25 tonne crane for construction. A suitable access route for these vehicles will need to be identified.

At the site, an access track will need to be constructed to the turbine locations. This would be composed of hardcore and is expected to be 4m wide with a depth of 300mm, subject to survey. A crane hard-standing of 10m x 10m will also be required, constructed to the same specification as the access track.

Foundation Design

The foundation is made up of high-strength concrete, steel reinforced mesh, and high tension foundation bolts. Adjustable piping, and tubing for the earthing and cabling will be buried within the concrete. Before the foundation construction takes place a geotechnical survey is required, and the exact foundation specification altered with respect to this.

The expected foundation size is 6 m x 6 m and between 1.8 and 2.4 m deep.
