Prairie Wind Transmission has started construction work on 108 miles of new double-circuit, 345kV transmission lines in south-central Kansas, US.
The project, estimated to cost $180m, will stretch from Colwich to a new substation at Medicine Lodge and then south to Hardtner at the Kansas-Oklahoma border.
Prairie Wind Transmission is a joint venture, which includes American Electric Power, MidAmerican Energy Holdings Company and Westar Energy.
AEP president and chief executive officer Nicholas K Akins said that the project would provide significant benefits for the transmission system in Kansas.
"Our nation needs new transmission infrastructure investment to ensure that we continue to have a reliable grid to support both changes in how we generate electricity and future economic growth," Atkins said. "Transmission investment also can support job growth throughout our economy.
"We have transmission companies approved in Indiana, Michigan, Ohio, Oklahoma and Virginia and are working through pending approvals in Arkansas, Kentucky, Louisiana and West Virginia.
"Our Electric Transmission Texas joint venture with MidAmerican has 55 projects under construction in the Electric Reliability Council of Texas, with a pipeline of projects totalling more than $2 billion by 2014."
The project is expected to reduce transmission congestion and will be the first high-voltage transmission line linking east and west Kansas.
Expected to be complete in late 2014, the project will improve reliability and support the growth of wind energy in the state.
