The company, under the contract, will be designing, supplying, installing and commissioning two 34.5/138 kilovolt (kV) substations, one 138/500kV substation, step-up power transformers and air- and gas-insulated switchgear.

ABB will also provide SCADA and telecommunication systems as well as IEC 61850 compliant substation automation, control and protection equipment.

The scope of the contract also includes supply and installation of two 138kV overhead transmission lines to connect a new 400 MW wind power plant.

ABB Power Systems division head Brice Koch said the substations will help to integrate wind energy and boost power supplies to meet growing industrial, commercial and residential demand.

"They will also reinforce the transmission grid and help improve reliability, efficiency and power quality," Koch added.

The step-up transformers aid in increasing the voltage of the electricity generated from wind project to integrate into the transmission grid while the substations transform the voltage levels and facilitates safe and efficient transmission and distribution of power.

Substations include equipment that control and protect electricity flow.

The project is scheduled for completion by 2014.
