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.

Wind Speed at Hub (m/s)
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.
