Gemma Renewable Power has won an engineering, procurement and construction (EPC) contract worth approximately $51m from Bishop Hill Energy, a wholly-owned subsidiary of Invenergy Wind North America, to design and build a 200MW wind farm in Illinois.

The Bishop Hill wind farm in Henry County is expected to consist of up to 134 units of GE turbines.

Gemma Renewable Power will design and construct foundations and electrical collection systems in addition to erecting towers, turbines and blades for the project.

The power project is anticipated to be completed in late 2011 and electricity generated from the wind farm will be sold to the Tennessee Valley Authority.

Gemma Renewable Power is a wholly-owned subsidiary of Gemma Power Systems, an EPC contractor providing a range of services to the power and alternative fuel industries.
