CPV Renewable Energy Company, LLC, a privately held company owned by Competitive Power Ventures, has chosen to strengthen its ties with Siemens in the energy business.

CPV has purchased 44 2.3 MW wind turbines from Siemens Power Generation. The two companies didn't share the financial details.

The turbines will be allocated to the Keenan wind project in Woodward County, Oklahoma.

Counting this order, Siemens has received six US wind turbine orders totaling more than 1,500MW to date in fiscal 2008.

Andreas Nauen, CEO, Siemens wind power business unit, said the US is the largest market for its wind turbines business. He added that Competitive Power Ventures selected Siemens for its first wind farm in Oklahoma, which will also be his company's first wind project in that state.

As per the information available, the Siemens scope of supply for the wind farm consists of delivery, installation and commissioning of 44 SWT-2.3-93 wind turbines with a capacity of 2.3MW each. A service and warranty agreement is also included in the order.

The delivery is scheduled for 2009. The Keenan wind farm is expected to increase Oklahoma's existing 700MW wind power capacity by 101MW, enough power to meet the electricity demand of approximately 30,000 households.

With projects underway in 12 states, CPV's portfolio of wind projects now totals over 5,000 MW. The initial phase of the Keenan project is expected to enter commercial operation in 2009.
