The Shepherds Flat Wind Farm project was a significant development in the region. It was the largest wind farm in the world at the time of its completion.
Located in Oregon, USA, the project spanned over 30 miles and consisted of 338 wind turbines. The turbines were installed on a 320-square-mile site.
The wind farm was developed by Caithness Development, a leading renewable energy company. The project was completed in 2012, after a series of construction phases.
The project's construction involved the installation of roads, foundations, and turbines, as well as the construction of a substation and transmission lines.
Location and Details
The Shepherds Flat Wind Farm is located in Oregon, USA, but the article doesn't specify the exact location.
The wind farm is equipped with 338 GE 2.5-100 series wind turbines, which feature permanent magnet generators that ensure high-efficiency even at low wind speeds.
Each of the three facilities has its own substation and operations and maintenance facility.
The wind turbines are divided among the three facilities, with 106 at Shepherds Flat North and 116 at each of the other two facilities.
The project involved the construction of 85 miles of road, which is a significant infrastructure development.
The underground collection system spans 136 miles, which is a massive undertaking requiring careful planning and execution.
The transmission line is 16 miles long and operates at 230kV, a notable feat of engineering.
Nine permanent meteorological evaluation towers (METs) were constructed to monitor the wind conditions, providing valuable data for the wind farm's operation.
The project's infrastructure is impressive, with multiple facilities, roads, and transmission lines all working together to generate clean energy.

Project Development
The Shepherds Flat Wind Farm is a massive project, with 303 wind turbines that can create 909 megawatts of power, enough to light up about 225,000 homes.
The project has faced significant challenges, including a months-long stand-off with the Pentagon over concerns about interfering with a nearby radar system.
The project will be the largest land-based wind energy project in the world, producing 845 megawatts of power, which is equivalent to a nuclear power plant.
Part #2:

The Shepherds Flat Wind Farm is a massive project with 303 wind turbines that can create 909 megawatts of power, enough to light up about 225,000 homes.
The project features 78 turbines from GE Energy2.5-100, which have a power output of 2,500 kW and a diameter of 100 m.
Here's a breakdown of the project's details:
- Location: Gilliam, Morrow
- Developer: Caithness/Blattner Energy
- Operator: Caithness
- Total nominal power: 195,000 kW
- Operational status: Operational
- Type: Onshore wind farm
This project is a significant investment in renewable energy, and its completion will be a major milestone in the development of clean energy in the region.
Contractors in Caithness
Caithness wind farm contractors played a crucial role in the project's success. GE's factories in Pensacola, Florida and Tehachapi, California manufactured the turbine components.
GE is also responsible for providing operation and maintenance services for the wind farm for ten years. This long-term commitment shows the company's confidence in the project's viability.
Winergy supplied its PZFB 3494 gearboxes and ARPEX ARV4 couplings for the project. These components are essential for the turbines' smooth operation.

The engineering, procurement and construction (EPC) contractor for the project was Blattner Energy. They handled the project's logistics and construction with ease.
GL Garrad Hassan performed the final independent engineering and wind resource assessment reports. Their expertise ensured that the project met the highest standards.
Daws Manufacturing provided the heat exchangers for the turbines, which were hot-dip galvanised to protect them from corrosion. This added layer of protection will extend the life of the turbines.
Project Scope
The Shepherds Flat Wind Farm is a massive project with a total of 338 wind turbines. Each of these turbines is a GE 2.5-100 series model, featuring permanent magnet generators that ensure high efficiency even at low wind speeds.
The project is divided into three facilities, with 106 turbines in the Shepherds Flat North facility and 116 turbines in each of the other two facilities. This setup allows for efficient operation and maintenance.
The wind farm generates a whopping 909 megawatts (MW) of power, which is enough to light up about 225,000 homes. This is a significant amount of electricity that can power a substantial number of households.

To support the turbines, a network of roads, collection systems, and transmission lines was constructed. Specifically, 85 miles of road and 136 miles of underground collection system were installed.
The project also included the installation of a 16-mile 230kV transmission line and the construction of one ring bus and nine permanent meteorological evaluation towers (METs).

Project Finances
Shepherds Flat Wind Farm was developed with an estimated investment of $1.9bn.
The US Department of Energy provided a partial loan guarantee of $1.3bn, which was arranged by 26 financial institutions led by Citibank, Bank of Tokyo-Mitsubishi UFJ, WestLB and RBS Securities.
Caithness Energy’s partners in the project invested $500m.
The loan guarantee was provided as part of the Recovery Act, with Shepherds Flat being the sixth project to receive financial assistance under this act.
Google announced its decision to invest $100m in the project in April 2011, making it the largest investment made by Google in renewable energy.
ITOCHU and Sumitomo Corporation are jointly investing $400m in the project.
