As part of the deal, Siemens will supply 28 SWT-2.3-108 type wind turbines for the project, which is expected to begin commercial operation in fall 2014.
The project is expected to provide clean energy to around 20,000 American households, with a total power output of about 67.6MW, according to Siemens.
Siemens also signed a service agreement to ensure reliability, availability and performance of the wind turbines.
Siemens Energy wind power division Markus Tacke said the equipment supplied by the company will be manufactured in the firm’s US plants in Iowa and Kansas to support domestic employment.
"We are proud to work with BlackRock and OwnEnergy on this project as it provides clean, renewable energy to the citizens of Texas," Tacke added.
Recently, OwnEnergy has divested a majority stake in the Windthorst-2 project to a fund managed by BlackRock, and plans to maintain a minority ownership interest and manage its construction.
