German industry giant Siemens has secured a wind turbine delivery order from Apex Clean Energy for the Grant Wind project in Oklahoma, US.

Located in Grant County, the renewable project will feature 66 Siemens SWT-2.3-108 wind turbines.

Each of the turbines to be installed at the facility will have a power rating of 2.3MW, and feature 53m blades, Siemens has said.

Once operational, the firm will be able to meet the energy requirements of around 50,000 average US households.

The firm will also offer remote monitoring and diagnostic services for the turbines in order to boost their performance throughout their operational life, as well as for the project.

Under the terms of the contract, Siemens will also supply a main step up transformer for the project and offer long term service and maintenance for the turbines.

Turbine installation for the facility has been scheduled to start in October this year, while commissioning of the power plant is expected in the spring of 2016.

"With this second order in one year, Apex Clean Energy continues our successful collaboration."

The order follows another contract awarded to the German company earlier in the year to deliver turbines, service and financing for Apex Clean Energy’s Kay wind project in Kay County, Oklahoma.

Siemens wind power and renewables division onshore CEO Thomas Richterich said: "With this second order in one year, Apex Clean Energy continues our successful collaboration.

"We are proud to meet the customers demand with our full spectrum of resources, including equipment, service and financing."

Once operational, the 299MW Kay wind project is expected to meet the electricity demands of 100,000 average US homes annually.
